Description 
Summary

The aim of this study was to obtain data on seasonal biomass variations and changes in taxonomic composition of the macroplankton and near- bottom fauna. Macroplankton was collected with a 500 microm Bongo net hauled at about 3 knots. At stations 92A and R6, single hauls were performed by submerging the net to a depth of about 25m. At station Z two hauls were made, one at 30m depth and the second one at 50m depth. At station G2 three hauls were performed at 30, 60 and 90m depths, respectively. An Ostroumov dredge of 300 microm mesh size was used for collecting the near-bottom fauna by dredging close to the bottom for a distance of about 200m. A total of 169 samples was analyzed. Samples were preserved with 4% formaldehyde-sea water solution, buffered with borax. The organisms were enumerated and measured under a binocular.
