Abstract

Anomalous phenomena in the development of phytoplankton in the Black Sea for the period of 2000–2020 have been recorded on the basis of satellite data. Anomalous summer blooms of diatoms were detected in the field of chlorophyll a for the blooming periods of 2001, 2010, and 2015. These blooms were unusual for the summer periods and developed under conditions of a negative anomaly in the surface layer temperature caused by active wind mixing. The highest level of development of summer blooms of coccolithophore was recorded in 2006, 2012, and 2017. These phenomena have been observed after abnormally cold winters. It has been shown that in some years, under conditions of low summer temperatures and active wind mixing, the summer vegetation of coccolithophores is poorly manifested and can be replaced by the development of diatoms. Satellite data over a twenty-year period demonstrated numerous signs of mass development of coccolithophores during the cold season. Winter blooms of coccolithophorids occur in warm winters with low wind activity. It has been noted that after the winter blooms of coccolithophores, their summer vegetation is largely smoothed. The influence of hydrometeorological factors on the seasonal and interannual variability of phytoplankton is discussed.

基于遥感数据的黑海浮游植物发育异常现象

摘要

根据卫星数据，记录了2000-2020年黑海浮游植物发展的异常现象。在叶绿素a领域检测到硅藻的夏季异常开花在2001年，2010年和2015年的盛花期。这些盛花在夏季不常见，并且是在活跃风混合引起的表层温度为负异常的条件下发展的。2006年，2012年和2017年记录了球石藻夏季开花的最高水平。在异常寒冷的冬季之后，观察到了这些现象。研究表明，在某些年份中，在夏季温度低和活跃的风混合的条件下，球墨镜的夏季植被表现得很差，可以被硅藻的发育所取代。二十年来的卫星数据表明，在寒冷季节，大量的球瓢虫鳞片出现了迹象。在低风活动的温暖冬季，会发生球花珊瑚的冬季开花。有人指出，在冬花椰菜花开之后，它们的夏季植被在很大程度上得到了抚平。讨论了水文气象因素对浮游植物季节和年际变化的影响。
