The flow of non-living carbon (detritus) is considered an important process because it connects ecosystems and fuels benthic communities. In Norwegian kelp forests, 90% of the kelp production is exported to adjacent ecosystems where it can play a significant role in shaping benthic communities. We quantified the major structural and functional traits of an Arctic deep-sea ecosystem associated with kelp exports and assessed the ecological role of kelp export into the deep-sea system. We first developed a food-web model using the Ecopath with Ecosim (EwE) approach to represent the state of the deep (450 m) ecosystem of the Malangen fjord (Northern Norway) in 2017. Subsequently, we used the temporal dynamic model Ecosim to explore the structure and functioning traits of a theoretical deep-sea ecosystem projecting a decrease of kelp detritus biomass reaching the deep-sea ecosystem. Overall, our findings reveal that kelp detritus from shallow coastal areas has a small but noticeable role structuring the deep-sea ecosystem of Malangen. The temporal simulations show important differences depending on the application of mediating effects, which allow considering the detritus as a mediating group in prey-predator interaction, in addition to its direct role in trophic relationships. When mediating effects are applied, biomass increases for benthopelagic shrimps and suprabenthos groups and decreases for rays and skates, velvet belly, rabbitfish and other commercial demersal fishes under the low kelp detritus scenarios. Biomass-based and trophic-based indicators reveal a noticeable impact on the deep-sea ecosystem structure due to depletion of kelp detritus. To further assess future changes of the Arctic deep-sea ecosystems, dependencies with adjacent ecosystems, such as kelp detritus production, should be included This work was funded by MARINFORSK Norwegian Research Council through the KELPEX project (NRC Grant no. 255085/E40).

This study aims to: (i) analyse the trophic functioning of the Celtic Sea and the Bay of Biscay, (ii) investigate ecosystem changes over the 1980–2013 period and, (iii) explore the response to management measures at the food web scale. Ecopath models were built for each ecosystem for years 1980 and 2013, and Ecosim models were fitted to time series data of biomass and catches. EcoTroph diagnosis showed that in both ecosystems, fishing pressure focuses on high trophic levels (TLs) and, to a lesser extent, on intermediate TLs. However, the interplay between local environmental conditions, species composition and ecosystem functioning could explain the different responses to fisheries management observed between these two contiguous ecosystems. Indeed, over the study period, the ecosystem's exploitation status has improved in the Bay of Biscay but not in the Celtic Sea. This improvement does not seem to be sufficient to achieve the objectives of an EAFM, as high trophic levels were still overexploited in 2013 and simulations conducted with Ecosim in the Bay of Biscay indicate that at current fishing effort the biomass will not be rebuilt by 2030. The ecosystem's response to a reduction in fishing mortality depends on which trophic levels receive protection. Reducing fishing mortality on pelagic fish, instead of on demersal fish, appears more efficient at maximising catch and total biomass and at conserving both top-predator and intermediate TLs. Such advice-oriented trophic models should be used on a regular basis to monitor the health status of marine food webs and analyse the trade-offs between multiple objectives in an ecosystem-based fisheries management context.

This study relates sea surface temperature (SST) to the upwelling conditions off the southwest coast of Portugal using statistical analyses of publically available data. Optimum Interpolation (OI) of daily SST data were extracted from the United States (US) National Oceanic and Atmospheric Administration (NOAA) and data for wind speed and direction were from the US National Climatic Data Center. Time series were extracted at a daily frequency for a time horizon of 26 years. Upwelling indices were estimated using westerly (Q(x)) and southerly (Q(y)) Ekman transport components.In the first part of the study, time series were inspected for trend and seasonality over the whole period. The seasonally adjusted time series revealed an increasing slope for SST (0.15 degrees C per decade) and decreasing slopes for Q(x) (84.01 m(3) s(-1) km(-1) per decade) and Q(y) (-25.20 m(3) s(-1) km(-1) per decade), over the time horizon. Structural breaks analysis applied to the time series showed that a statistically significant incremental increase in SST was more pronounced during the last decade.Cross -correlation between upwelling indices and SST revealed a time delay of 5 and 2 days between Q(x) and SST, and between Qv and SST, respectively. A spectral analysis combined with the previous analysis enabled the identification of four oceanographic seasons. Those seasons were later recognised over a restricted time period of 4 years, between 2008 and 2012, when there was an extensive sampling programme for the validation of ocean colour remote sensing imagery. The seasons were defined as: summer, with intense and regular events of upwelling; autumn, indicating relaxation of upwelling conditions; and spring and winter, showing high inter annual variability in terms of number and intensity of upwelling events.

Puillat; P. Farcy; D. Durand; B. Karlson; G. Petihakis; J. Seppälä; S. Sparnocchia;Coastal systems are of the most productive ones although they are the most impacted by direct pressures from human activities. These ecosystems exhibit a high level of complexity with many different and interconnected processes operating at various spatial and temporal scales and providing a range of ecosystem services. Coastal observations are tremendous importance in order to understand those complex marine processes. Moreover, they support the use and further development of coastal ocean numericalmodels, including physicalmodels and coupled physical-biogeochemical models. Coastal data have also many applications in the domain of coastal engineering such as for instance in the design of a coastal structure, or in the prevention of extreme events (e.g. flooding). As a consequence, the number of marine observing systems has quickly increased around European coastal seas, under the pressure of both monitoring requirements and marine research. Present demands for such observing systems include reliable, high-quality and comprehensive observations of key environmental parameters, automated platforms and sensors systems for continuous observations, as well as autonomy over long time periods. In-situ data collected can be combined with remote sensing and/or models to detect, understand and/or forecast the most crucial coastal processes over extensive areas within the various marine environments. In Europe, significant heterogeneity exists when it relates to marine observing systems, would it be technological design, measured parameters, practices for maintenance and quality control, as well as quality standards for sensors and data exchange. This can partly be explained by the fact that, most "coastal observatories" have been designed following national/regional research priorities and mainly undertaken through a series of short-term research projects. A main challenge for the European marine research community is therefore to harmonise the technologies, increase the consistency and the sustainability of these infrastructures by sharing know-how, establishing best practices and s agreeing on a consensual roadmap for the future of coastal observatories within a shared pan-European framework. These considerations led about thirty institutions in Europe to organise their coastal observation systems in a pan European Research Infrastructure: the JERICO-RI (www.jerico-ri.eu), and to build up this integrated infrastructure following a long-term approach This article and the following in this special issue of Journal of Marine Systems are focusing on some results of the FP7 JERICO project (2011-2015), which is briefly presented in the next section. Section 3 introduces the articles of this special issue, presenting the most relevant results supported by the use and the further development of the JERICO-RI. Some general conclusions are drawn in Section 4.

The analysis of deep-water glider hydrographic and fluorescence data, together with satellite measurements provides a new insight into eddy-induced anomalies within the South-Eastern Bay of Biscay, during summer. Two cyclonic eddies and a SWODDY have been observed in different glider transects and by means of different sources of satellite data. Vertical profiles reveal complex structures (characteristic of the second baroclinic mode): upward/downward displacement of the seasonal/permanent thermocline in the case of X13 and the opposite thermocline displacements in the case of the cyclones. This is a typical behaviour of mode-water and “cyclonic thinny” eddies. A qualitative analysis of the vertical velocities in the anticyclone indicates that though geostrophy dominates the main water column, depressing the isopycnals, near the sea-surface the eddy-wind interaction affects the vertical currents, favouring Ekman pumping and upwelling. The analysis of the Θ-S properties corroborates that inside cyclones and between the 26 and 27 isopycnals, net downwelling occurs. These two types of intra-thermocline lenses appear to deeply impact the Chl-a fluorescence profiles, since the maximum Chl-a fluorescence is located just below the seasonal thermocline. The mean Chl-a fluorescence was higher in the anticyclone than within the cyclones and the mean for the entire study period; the highest values were observed in the centre of the anticyclone. These results are in agreement with previous findings concerning the SWODDY F90 and surrounding cyclones, located in the South-Western Bay of Biscay. Significant differences in the Θ-S properties of the two cyclonic mesoscale structures have been observed: higher temperatures and lower salinity in the easternmost cyclone. Finally, time variation of the salinity content of the shallowest water masses of the anticyclone (salinity decreasing over time), probably indicates advective mixing processes occurred during the mission. The work was supported by the JERICO project (2011-2015) from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 262584. This study has been also undertaken with the financial support of the Spanish Ministry of Economy and Competitiveness (National Plan for Scientific and Technical Research and Innovation, CTM2013-45423-R project) and the Department of Environment, Regional Planning, Agriculture and Fisheries of the Basque Government (Marco Program). The glider was provided and piloted by the INSU-CNRS; the mission was carried out with the inestimable help of Laurent Beguery in piloting the glider and advising us in the design of the mission. Support from the EGO COST ActionES0904 and the FP7 GROOM project (Grant agreement no. 284321) is acknowledged. Peer Reviewed

The evaluation of marine carbonate system variability and the impacts of ocean acidification (OA) on coastal marine ecosystems increasingly rely on monitoring platforms capable of delivering near real-time in situ carbonate system observations. These observations are also used for developing models and scenarios of OA, including potential impacts on marine ecosystem structure and function. An embedded flow-through spectrophotometric pH detection system has been developed alongside an underway seawater sampling system – termed a FerryBox – operating on ships of opportunity (SOOP), and can deliver a continuous data stream of mixed layer seawater pH with an in situ uncertainty of < 0.003. We report metrological approaches behind the pH detection procedure and the evaluation of dye addition perturbation with analytical precision as low as 0.0005. In addition, we present field-based observations from a deployment of the pH detection system along the Norwegian Coastal Current in winter, spring, and summer periods of 2015. Spring and summertime pH was generally ~ 0.1 higher, and up to ~ 0.255 higher, in comparison to winter pH observations. Here we show the necessity for a regular, high density monitoring approach, and the suitability of this pH detection technique for unmanned observational platforms.

Such monitoring is required by the European Marine StrategyFramework Directive (MSFD) in order to ensure the Good Environmental Status (GES) of Europeancoastal and offshore marine ecosystems. Time and cost-effective, automatic, techniques are of highinterest in this context. An imaging-based protocol has been applied to a high frequency time series(every second day between April 2003 to April 2004 on average) of zooplankton obtained in a coastalsite of the NW Mediterranean Sea, Villefranche Bay. One hundred eighty four mesozooplankton netcollected samples were analysed with a Zooscan and an associated semi-automatic classificationtechnique. The constitution of a learning set designed to maximize copepod identification with morethan 10,000 objects enabled the automatic sorting of copepods with an accuracy of 91% (true positives)and a contamination of 14% (false positives). Twenty seven samples were then chosen from the totalcopepod time series for detailed visual sorting of copepods after automatic identification. This methodenabled the description of the dynamics of two well-known copepod species, Centropages typicus andTemora stylifera, and 7 other taxonomically broader copepod groups, in terms of size, biovolume andabundance–size distributions (size spectra). Also, total copepod size spectra underwent significantchanges during the sampling period. These changes could be partially related to changes in thecopepod assemblage taxonomic composition and size distributions. This study shows that the use ofhigh throughput imaging systems is of great interest to extract relevant coarse (i.e. total abundance,size structure) and detailed (i.e. selected species dynamics) descriptors of zooplankton dynamics.Innovative zooplankton analyses are therefore proposed and open the way for further development ofzooplankton community indicators of changes International audience

In the Bay of Biscay and the English Channel, the diversity of involved processes (e.g. tidally-driven circulation, plume dynamics) requires to adapt observing systems to the specific targeted environments. Also important is the requirement for those systems to sustain coastal applications. Two observational network design experiments have been implemented for the spring season in two regions: the Loire River plume (northern part of the Bay of Biscay) and the Western English Channel. The method used to perform these experiments is based on the ArM (Array Modes) formalism using an ensemble-based approach without data assimilation. The first experiment in the Loire River plume aims to explore different possible glider endurance lines combined with a fixed mooring to monitor temperature and salinity. Main results show an expected improvement when combining glider and mooring observations. The experiment also highlights that the chosen transect (along-shore and North-South, cross-shore) does not significantly impact the efficiency of the network. Nevertheless, the classification from the method results in slightly better performances for along-shore and North-South sections. In the Western English Channel, a tidally-driven circulation system, added value of using a glider below FerryBox temperature and salinity measurements has been assessed. FerryBox systems are characterised by a high frequency sampling rate crossing the region 2 to 3 times a day. This efficient sampling, as well as the specific vertical hydrological structure (which is homogeneous in many sub-regions of the domain), explains the fact that the added value of an associated glider transect is not significant. These experiments combining existing and future observing systems, as well as numerical ensemble simulations, highlight the key issue of monitoring the whole water column in and close to river plumes (using gliders for example) and the efficiency of the surface high frequency sampling from FerryBoxes in macrotidal regions.

By combining synoptic measurements of the carbonate system with in situ determinations of the primary production (14C incorporation technique) and secondary prokaryotic carbon production (3H-leucine incorporation) along a river–sea gradient, we showed that the conservative mixing between river endmember and off-shore waters was the main driver of the dissolved inorganic carbon (DIC) distribution and seasonal variation. However, during spring and summer seasons also the influence of biological uptake and release of DIC was significant. In the surface water of June 2012, the spreading and persistence of nutrient-rich freshwater stimulated the primary production (3.21 μg C L− 1 h− 1) and net biological DIC decrease (− 100 μmol kg− 1), reducing the dissolved CO2 concentration and increasing the pHT. Below the pycnocline of August 2012, instead, an elevated bacterial carbon production rate (0.92 μg C L− 1 h− 1) was related with net DIC increase (92 μmol kg− 1), low dissolved oxygen concentration, and strong pHT reduction, suggesting the predominance of bacterial heterotrophic respiration over primary production. The flux of carbon dioxide estimated at the air–sea interface exerted a low influence on the seasonal variation of the carbonate system. A complex temporal and spatial dynamic of the air–sea CO2 exchange was also detected, due to the combined effects of seawater temperature, river discharge, and water circulation. On annual scale the system was a sink of atmospheric CO2. However, in summer and during elevated riverine discharges, the area close to the river's mouth acted as a source of carbon dioxide. Also the wind speed was crucial in controlling the air–sea CO2 exchange, with strong Bora events (a typical ENE wind of the Gulf of Trieste) that drastically increased the absorption (− 32.2 mmol m− 2 day− 1) or the release (5.34 mmol m− 2 day− 1) of carbon dioxide.

The flow of non-living carbon (detritus) is considered an important process because it connects ecosystems and fuels benthic communities. In Norwegian kelp forests, 90% of the kelp production is exported to adjacent ecosystems where it can play a significant role in shaping benthic communities. We quantified the major structural and functional traits of an Arctic deep-sea ecosystem associated with kelp exports and assessed the ecological role of kelp export into the deep-sea system. We first developed a food-web model using the Ecopath with Ecosim (EwE) approach to represent the state of the deep (450 m) ecosystem of the Malangen fjord (Northern Norway) in 2017. Subsequently, we used the temporal dynamic model Ecosim to explore the structure and functioning traits of a theoretical deep-sea ecosystem projecting a decrease of kelp detritus biomass reaching the deep-sea ecosystem. Overall, our findings reveal that kelp detritus from shallow coastal areas has a small but noticeable role structuring the deep-sea ecosystem of Malangen. The temporal simulations show important differences depending on the application of mediating effects, which allow considering the detritus as a mediating group in prey-predator interaction, in addition to its direct role in trophic relationships. When mediating effects are applied, biomass increases for benthopelagic shrimps and suprabenthos groups and decreases for rays and skates, velvet belly, rabbitfish and other commercial demersal fishes under the low kelp detritus scenarios. Biomass-based and trophic-based indicators reveal a noticeable impact on the deep-sea ecosystem structure due to depletion of kelp detritus. To further assess future changes of the Arctic deep-sea ecosystems, dependencies with adjacent ecosystems, such as kelp detritus production, should be included This work was funded by MARINFORSK Norwegian Research Council through the KELPEX project (NRC Grant no. 255085/E40).

This study aims to: (i) analyse the trophic functioning of the Celtic Sea and the Bay of Biscay, (ii) investigate ecosystem changes over the 1980–2013 period and, (iii) explore the response to management measures at the food web scale. Ecopath models were built for each ecosystem for years 1980 and 2013, and Ecosim models were fitted to time series data of biomass and catches. EcoTroph diagnosis showed that in both ecosystems, fishing pressure focuses on high trophic levels (TLs) and, to a lesser extent, on intermediate TLs. However, the interplay between local environmental conditions, species composition and ecosystem functioning could explain the different responses to fisheries management observed between these two contiguous ecosystems. Indeed, over the study period, the ecosystem's exploitation status has improved in the Bay of Biscay but not in the Celtic Sea. This improvement does not seem to be sufficient to achieve the objectives of an EAFM, as high trophic levels were still overexploited in 2013 and simulations conducted with Ecosim in the Bay of Biscay indicate that at current fishing effort the biomass will not be rebuilt by 2030. The ecosystem's response to a reduction in fishing mortality depends on which trophic levels receive protection. Reducing fishing mortality on pelagic fish, instead of on demersal fish, appears more efficient at maximising catch and total biomass and at conserving both top-predator and intermediate TLs. Such advice-oriented trophic models should be used on a regular basis to monitor the health status of marine food webs and analyse the trade-offs between multiple objectives in an ecosystem-based fisheries management context.

This study relates sea surface temperature (SST) to the upwelling conditions off the southwest coast of Portugal using statistical analyses of publically available data. Optimum Interpolation (OI) of daily SST data were extracted from the United States (US) National Oceanic and Atmospheric Administration (NOAA) and data for wind speed and direction were from the US National Climatic Data Center. Time series were extracted at a daily frequency for a time horizon of 26 years. Upwelling indices were estimated using westerly (Q(x)) and southerly (Q(y)) Ekman transport components.In the first part of the study, time series were inspected for trend and seasonality over the whole period. The seasonally adjusted time series revealed an increasing slope for SST (0.15 degrees C per decade) and decreasing slopes for Q(x) (84.01 m(3) s(-1) km(-1) per decade) and Q(y) (-25.20 m(3) s(-1) km(-1) per decade), over the time horizon. Structural breaks analysis applied to the time series showed that a statistically significant incremental increase in SST was more pronounced during the last decade.Cross -correlation between upwelling indices and SST revealed a time delay of 5 and 2 days between Q(x) and SST, and between Qv and SST, respectively. A spectral analysis combined with the previous analysis enabled the identification of four oceanographic seasons. Those seasons were later recognised over a restricted time period of 4 years, between 2008 and 2012, when there was an extensive sampling programme for the validation of ocean colour remote sensing imagery. The seasons were defined as: summer, with intense and regular events of upwelling; autumn, indicating relaxation of upwelling conditions; and spring and winter, showing high inter annual variability in terms of number and intensity of upwelling events.

Puillat; P. Farcy; D. Durand; B. Karlson; G. Petihakis; J. Seppälä; S. Sparnocchia;Coastal systems are of the most productive ones although they are the most impacted by direct pressures from human activities. These ecosystems exhibit a high level of complexity with many different and interconnected processes operating at various spatial and temporal scales and providing a range of ecosystem services. Coastal observations are tremendous importance in order to understand those complex marine processes. Moreover, they support the use and further development of coastal ocean numericalmodels, including physicalmodels and coupled physical-biogeochemical models. Coastal data have also many applications in the domain of coastal engineering such as for instance in the design of a coastal structure, or in the prevention of extreme events (e.g. flooding). As a consequence, the number of marine observing systems has quickly increased around European coastal seas, under the pressure of both monitoring requirements and marine research. Present demands for such observing systems include reliable, high-quality and comprehensive observations of key environmental parameters, automated platforms and sensors systems for continuous observations, as well as autonomy over long time periods. In-situ data collected can be combined with remote sensing and/or models to detect, understand and/or forecast the most crucial coastal processes over extensive areas within the various marine environments. In Europe, significant heterogeneity exists when it relates to marine observing systems, would it be technological design, measured parameters, practices for maintenance and quality control, as well as quality standards for sensors and data exchange. This can partly be explained by the fact that, most "coastal observatories" have been designed following national/regional research priorities and mainly undertaken through a series of short-term research projects. A main challenge for the European marine research community is therefore to harmonise the technologies, increase the consistency and the sustainability of these infrastructures by sharing know-how, establishing best practices and s agreeing on a consensual roadmap for the future of coastal observatories within a shared pan-European framework. These considerations led about thirty institutions in Europe to organise their coastal observation systems in a pan European Research Infrastructure: the JERICO-RI (www.jerico-ri.eu), and to build up this integrated infrastructure following a long-term approach This article and the following in this special issue of Journal of Marine Systems are focusing on some results of the FP7 JERICO project (2011-2015), which is briefly presented in the next section. Section 3 introduces the articles of this special issue, presenting the most relevant results supported by the use and the further development of the JERICO-RI. Some general conclusions are drawn in Section 4.

The analysis of deep-water glider hydrographic and fluorescence data, together with satellite measurements provides a new insight into eddy-induced anomalies within the South-Eastern Bay of Biscay, during summer. Two cyclonic eddies and a SWODDY have been observed in different glider transects and by means of different sources of satellite data. Vertical profiles reveal complex structures (characteristic of the second baroclinic mode): upward/downward displacement of the seasonal/permanent thermocline in the case of X13 and the opposite thermocline displacements in the case of the cyclones. This is a typical behaviour of mode-water and “cyclonic thinny” eddies. A qualitative analysis of the vertical velocities in the anticyclone indicates that though geostrophy dominates the main water column, depressing the isopycnals, near the sea-surface the eddy-wind interaction affects the vertical currents, favouring Ekman pumping and upwelling. The analysis of the Θ-S properties corroborates that inside cyclones and between the 26 and 27 isopycnals, net downwelling occurs. These two types of intra-thermocline lenses appear to deeply impact the Chl-a fluorescence profiles, since the maximum Chl-a fluorescence is located just below the seasonal thermocline. The mean Chl-a fluorescence was higher in the anticyclone than within the cyclones and the mean for the entire study period; the highest values were observed in the centre of the anticyclone. These results are in agreement with previous findings concerning the SWODDY F90 and surrounding cyclones, located in the South-Western Bay of Biscay. Significant differences in the Θ-S properties of the two cyclonic mesoscale structures have been observed: higher temperatures and lower salinity in the easternmost cyclone. Finally, time variation of the salinity content of the shallowest water masses of the anticyclone (salinity decreasing over time), probably indicates advective mixing processes occurred during the mission. The work was supported by the JERICO project (2011-2015) from the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement no. 262584. This study has been also undertaken with the financial support of the Spanish Ministry of Economy and Competitiveness (National Plan for Scientific and Technical Research and Innovation, CTM2013-45423-R project) and the Department of Environment, Regional Planning, Agriculture and Fisheries of the Basque Government (Marco Program). The glider was provided and piloted by the INSU-CNRS; the mission was carried out with the inestimable help of Laurent Beguery in piloting the glider and advising us in the design of the mission. Support from the EGO COST ActionES0904 and the FP7 GROOM project (Grant agreement no. 284321) is acknowledged. Peer Reviewed

The evaluation of marine carbonate system variability and the impacts of ocean acidification (OA) on coastal marine ecosystems increasingly rely on monitoring platforms capable of delivering near real-time in situ carbonate system observations. These observations are also used for developing models and scenarios of OA, including potential impacts on marine ecosystem structure and function. An embedded flow-through spectrophotometric pH detection system has been developed alongside an underway seawater sampling system – termed a FerryBox – operating on ships of opportunity (SOOP), and can deliver a continuous data stream of mixed layer seawater pH with an in situ uncertainty of < 0.003. We report metrological approaches behind the pH detection procedure and the evaluation of dye addition perturbation with analytical precision as low as 0.0005. In addition, we present field-based observations from a deployment of the pH detection system along the Norwegian Coastal Current in winter, spring, and summer periods of 2015. Spring and summertime pH was generally ~ 0.1 higher, and up to ~ 0.255 higher, in comparison to winter pH observations. Here we show the necessity for a regular, high density monitoring approach, and the suitability of this pH detection technique for unmanned observational platforms.

Such monitoring is required by the European Marine StrategyFramework Directive (MSFD) in order to ensure the Good Environmental Status (GES) of Europeancoastal and offshore marine ecosystems. Time and cost-effective, automatic, techniques are of highinterest in this context. An imaging-based protocol has been applied to a high frequency time series(every second day between April 2003 to April 2004 on average) of zooplankton obtained in a coastalsite of the NW Mediterranean Sea, Villefranche Bay. One hundred eighty four mesozooplankton netcollected samples were analysed with a Zooscan and an associated semi-automatic classificationtechnique. The constitution of a learning set designed to maximize copepod identification with morethan 10,000 objects enabled the automatic sorting of copepods with an accuracy of 91% (true positives)and a contamination of 14% (false positives). Twenty seven samples were then chosen from the totalcopepod time series for detailed visual sorting of copepods after automatic identification. This methodenabled the description of the dynamics of two well-known copepod species, Centropages typicus andTemora stylifera, and 7 other taxonomically broader copepod groups, in terms of size, biovolume andabundance–size distributions (size spectra). Also, total copepod size spectra underwent significantchanges during the sampling period. These changes could be partially related to changes in thecopepod assemblage taxonomic composition and size distributions. This study shows that the use ofhigh throughput imaging systems is of great interest to extract relevant coarse (i.e. total abundance,size structure) and detailed (i.e. selected species dynamics) descriptors of zooplankton dynamics.Innovative zooplankton analyses are therefore proposed and open the way for further development ofzooplankton community indicators of changes International audience

In the Bay of Biscay and the English Channel, the diversity of involved processes (e.g. tidally-driven circulation, plume dynamics) requires to adapt observing systems to the specific targeted environments. Also important is the requirement for those systems to sustain coastal applications. Two observational network design experiments have been implemented for the spring season in two regions: the Loire River plume (northern part of the Bay of Biscay) and the Western English Channel. The method used to perform these experiments is based on the ArM (Array Modes) formalism using an ensemble-based approach without data assimilation. The first experiment in the Loire River plume aims to explore different possible glider endurance lines combined with a fixed mooring to monitor temperature and salinity. Main results show an expected improvement when combining glider and mooring observations. The experiment also highlights that the chosen transect (along-shore and North-South, cross-shore) does not significantly impact the efficiency of the network. Nevertheless, the classification from the method results in slightly better performances for along-shore and North-South sections. In the Western English Channel, a tidally-driven circulation system, added value of using a glider below FerryBox temperature and salinity measurements has been assessed. FerryBox systems are characterised by a high frequency sampling rate crossing the region 2 to 3 times a day. This efficient sampling, as well as the specific vertical hydrological structure (which is homogeneous in many sub-regions of the domain), explains the fact that the added value of an associated glider transect is not significant. These experiments combining existing and future observing systems, as well as numerical ensemble simulations, highlight the key issue of monitoring the whole water column in and close to river plumes (using gliders for example) and the efficiency of the surface high frequency sampling from FerryBoxes in macrotidal regions.

By combining synoptic measurements of the carbonate system with in situ determinations of the primary production (14C incorporation technique) and secondary prokaryotic carbon production (3H-leucine incorporation) along a river–sea gradient, we showed that the conservative mixing between river endmember and off-shore waters was the main driver of the dissolved inorganic carbon (DIC) distribution and seasonal variation. However, during spring and summer seasons also the influence of biological uptake and release of DIC was significant. In the surface water of June 2012, the spreading and persistence of nutrient-rich freshwater stimulated the primary production (3.21 μg C L− 1 h− 1) and net biological DIC decrease (− 100 μmol kg− 1), reducing the dissolved CO2 concentration and increasing the pHT. Below the pycnocline of August 2012, instead, an elevated bacterial carbon production rate (0.92 μg C L− 1 h− 1) was related with net DIC increase (92 μmol kg− 1), low dissolved oxygen concentration, and strong pHT reduction, suggesting the predominance of bacterial heterotrophic respiration over primary production. The flux of carbon dioxide estimated at the air–sea interface exerted a low influence on the seasonal variation of the carbonate system. A complex temporal and spatial dynamic of the air–sea CO2 exchange was also detected, due to the combined effects of seawater temperature, river discharge, and water circulation. On annual scale the system was a sink of atmospheric CO2. However, in summer and during elevated riverine discharges, the area close to the river's mouth acted as a source of carbon dioxide. Also the wind speed was crucial in controlling the air–sea CO2 exchange, with strong Bora events (a typical ENE wind of the Gulf of Trieste) that drastically increased the absorption (− 32.2 mmol m− 2 day− 1) or the release (5.34 mmol m− 2 day− 1) of carbon dioxide.
