Composition of bottom sediments from Mediterranean anoxis basins

Biomass and size structure of planktic infusoria communities were investigated in March 1987 at nine stations on a 370 mile transect across the coastal upwelling zone, the California current, and subtropical waters. Infusoria compose up to 71-92% of total biomass of heterotrophic micro- and nannoplankton; their biomass was 0.6-2.0 g/m**2 in the 0-200 m layer. Distinctive characteristics of taxonomic and size structures were of great diversity of microplanktic Stormbilidiwn forms, comparatively low abundance of tintinnids, and high abundance of nannoplanktic infusoria that accounted for 26-54% of biomass.

Geochemical parameters of sediments and waters in areas of ocean barrier zones

Geochemical barrier zones play an important role in determining various physical systems and characteristics of oceans, e.g. hydrodynamics, salinity, temperature and light. In the book each of more than 30 barrier zones are illustrated and defined by physical, chemical and biological parameters. Among the topics discussed are processes of inflow, transformation and precipitation of the sedimentary layer of the open oceans and more restricted areas such as the Baltic, Black and Mediterranean Seas.
