Abundance and biomass of phytoplankton in the water column in the northern subtropical Pacific

Species composition, cell number and biomass of pico-, nanno- and microalgae were estimated for open waters of the northern subtropical zone of the Pacific Ocean and coastal waters off the North America. Total phytoplankton abundance was also evaluated. Productivity of these waters was newly estimated. Distribution of phytoplankton, its size, and taxonomic groups were compared with chlorophyll distribution estimated during the same cruise. Dissimilarities between distribution of small and large forms result from their adaptation to various peculiarities of the environment.

Some parameters of distribution of hydrocarbon paraffin fraction in bottom sediments of the Kara Sea and the Yenisey estuary

During Cruise 49 of R/V Dmitry Mendeleev in the Kara Sea (August-September, 1993) chemical-bitumenological studies of bottom sediments were carried out. Hydrocarbons were analyzed by gas-liquid chromatography. It was found on the basis of distribution of n-alkanes and isoprenoids (pristan and phytan) that organic matter is mainly terrigenous consisting of higher plant remains.
