Night biomass of dominant mesozooplankton groups within the Bismark Polygon (Northeast Atlantic) in June 2001 and June-August 2002

Vertical zooplankton distribution at the northeastern periphery of the North Atlantic subtropical gyre was studied with the use of 113/140 BR nets and Mir manned submersibles. Vertical distribution of selected dominant taxonomic, ecological, and trophic groups was considered. Results were compared with data obtained at the same location in 2001 that allowed to estimate interannual variability of the planktonic community.

Abundance and chemical and mineral compositions of nodules from the Pacific Ocean

The monograph highlights extensive materials collected during expeditions of P.P. Shirshov Institute of Oceanology. We consider facial conditions of nodule formation, regularities of their distribution, stratigraphic position, petrography, mineral composition, textures, geochemistry of nodules and hosting sediments. Origin of iron-manganese nodules in the Pacific Ocean is considered as well.
