METHOD TO RESEARCH SMALL-SCALE STRUCTURE AND PHYSIOLOGICAL CONDITION OF MARINE PLANKTONIC COMMUNITIES

摘要

FIELD: measurement equipment.;SUBSTANCE: by multiple probing of a photic layer by two instruments ("SALPA" and "PLANKTON-3"), which are rigidly engaged at one frame, research is provided for small-scale space-time variability of bioluminescent and hydroacoustic characteristics and physiological condition of marine plankton groups.;EFFECT: due to synchronism of vertical probings of a photic layer by two instruments, which are in a rigid engagement on the same frame, considerable economic effect is achieved due to reduction of time, which is provided on drifting stations for bioluminescent and hydroacoustic measurements.
