Presented are physical and biological data for the region extending from the Barents Sea to the Kara Sea during 158 scientific cruises for the period 1913-1999. Maps with the temporal distribution of physical and biological variables of the Barents and Kara Seas are presented, with proposed quality control criteria for phytoplankton and zooplankton data. Changes in the plankton community structure between the 1930s, 1950s, and 1990s are discussed. Multiple tables of Arctic Seas phytoplankton and zooplankton species are presented, containing ecological and geographic characteristics for each species, and images of live cells for the dominant phytoplankton species.

Cyst assemblages from Sites 548, 549, and 550 were examined and gave evidence of early Eocene to late Miocene age. These assemblages were compared with other North Atlantic DSDP sites and with onshore sections in Denmark, southern England, Spain, and Italy. Some environmental interpretation is attempted for the Miocene assemblages; pollen, spores, and dinoflagellate cyst species were used to interpret the proximity of the shoreline. Key species are illustrated, along with some forms that are not discussed.
