Abstract

The causes and features of the variability of the bioluminescence intensity of the plankton community in the spring and autumn periods along the coast of Crimea are analyzed based on expedition and satellite data. It is noted that synoptic and mesoscale vortex processes exert a significant impact on the vertical profile of the bioluminescence intensity in hydrobionts and must be taken into account in the analysis of the seasonal variability of bioluminescence parameters. The concept of integral hydrobiont bioluminescence intensity (IHBI) is introduced; it allows one to estimate the total biomass of hydrobionts inhabiting the depth range under consideration. It is found that the average IHBI in the northern part of the Black Sea in the autumn period is higher than in spring by more than ten times. It is noted that mesoscale vortex formations exert the greatest effect on the IHBI in the region of the continental slope.

春秋战国时期黑海近岸浮游生物群落生物发光强度的变化特征

摘要

基于远征和卫星数据，分析了克里米亚沿海春季和秋季的浮游生物群落生物发光强度变化的原因和特征。要注意的是，天气尺度和中尺度涡旋过程对水生生物体内生物发光强度的垂直分布有重大影响，在分析生物发光参数的季节变化时必须考虑到这一点。介绍了整体水生生物发光强度（IHBI）的概念。它使人们能够估计居住在所考虑深度范围内的水溶生物的总生物量。结果发现，秋季黑海北部地区的平均IHBI比春季高出十倍以上。
