Abundance and biomass of macrobenthos in the western part of the Black Sea during Mare Nigrum cruise S-RO2

Dataset containing macrobenthos data for samples collected during September 2008 in the North-West Black Sea (between 44°46' - 43°45' N latitude and 30° 11' - 29°35' E longitude). Macrobenthos sampling was done in 4 stations using a 0.14 m**2 Van Veen grab. Washing of the sample through two sieves - 1 mm and 0.25 mm mesh size; the material retained by the two sieves was examined at the binocular microscope; all animals were extracted, using fine tweezers and the species or group of species were identified and counted (in order to determine the density of populations); the larger organisms were measured and weighed (structure and biomass); for smaller organisms, the average wet weights inscribed in standard tables were used to calculate the biomass. Taxonomic identification was done at the GeoEcoMar by A. Teaca and T. Begun using the relevant taxonomic literature ( "Key-book for the identification of the Black Sea and Sea of Azov Fauna, 1968 -1972, Kiev - in Russian, V 1-4; BACESCU, M.C., MÜLLER, G. I., GOMOIU, M.-T., 1971). BACESCU, M.C., MÜLLER, G. I., GOMOIU, M.-T., 1971-Benthic ecological research to Black Sea. Comparative quantitative and qualitative analyse of pontic benthic fauna.

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.
