(Table 1) Biomass of plankton in the Sea of Japan at Station VITYAZ6674

Vertical distribution of zooplankton biomass from the surface to bottom layers (3400 m) is examined. Material was collected layer by layer by a BR 113/140 net at 41°59' N and 133°37' E on July 2 and 3, 1970. Quantity of plankton below 1000 m was found to be much less than at corresponding depths in the adjacent regions of the ocean. This impoverishment is due to absence of oceanic bathypelagic animals in deep layers of the Sea of Japan. Absence of specialized predators (plankton-feeders) deep in the Sea of Japan results in underconsumption of interzonal animals that sink to great depths. Upon dying they should reach the floor in larger quantities than in the ocean.

Composition of benthic taxa collected during POLARSTERN cruise ANT-XXI/5 (BENDEX) at Bouvet Island and Spiess Seamound

Bouvet (Bouvetøya) is a geologically young and very remote island just south of the Polar Front. Here we report samples taken during the RV "Polarstern" cruise ANTXXI/2 on 3 days in November 2003 and January 2004. This work was part of SCAR's EASIZ programme and intended, by providing data on the marine fauna of this "white gap" in the Atlantic sector of the Southern Ocean, to contribute to identifying the role of Bouvet in the faunal exchange between the Sub- and high Antarctic. While this goal demands extensive molecular analysis of the material sampled (future work), a checklist of the samples and data at hand widens the faunal and environmental inventory substantially. We suggest some preliminary conclusions on the relationship of Bouvet Island's fauna with that of other regions, such as Magellanic South America, the Antarctic Peninsula, and the high Antarctic Weddell Sea, which have been sampled previously. There seem to be different connections for individual higher taxa rather than a generally valid consistent picture.

Biological Atlas of the Arctic Seas 2000: Physical oceanography, hydrochemistry, meteorology, and plankton of the Barents and Kara Seas

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.
