Databases are “platforms” of high use and importance in the further work and analyses of the data. Many databases exist, but few are linked. Most databases are often hard to access without a high level of expertise. However, work is ongoing in this field, both toward higher accessibility and to better linkage among the databases.
Of special interest can be mentioned the newly developed hydrographic Atlas for the Barents Sea (quarterly values), and the fish stomach databases at IMR and PINRO (contained approximately 380 thousand stomachs by the end of 2006, Dolgov et al., 2007).
Several international hindcast databases (e.g.. NCEP, ERA40) are available. They use a combination of numerical models and available observations to estimate several climate variables, covering the whole world.
