The Bjerknes Climate Data Centre (BCDC) serves the data and syntheses obtained and assembled by researchers within the Bjerknes Centre for Climate Research (BCCR). All data from the different disciplines at BCCR (e.g. geology, oceanography, biology, model community) will be archived, interconnected and made publicly available in this long-term repository, by the BCDC. BCDC will become an Associated Data Unit (ADU) under IODE, International Oceanographic Data and Information Exchange, a worldwide network that operates under the auspices of the Intergovernmental Oceanographic Commission of UNESCO and aims to become a part of ICSU World Data System.
