A time-series observation of Asterionellopsis glacialis (Castracane) Round 1990 bloom in the surf zone of east coast of India and associated physico-chemical parameters, was carried out during pre-monsoon period (May 2018). This study also reviews the species status as a surf-zone diatom and its temporal characteristics. Referring to the earlier study, the temporal characteristic of A. glacialis bloom in Indian context can be classified as ―sporadic‖ due to the alteration of blooming community and may be also further investigated for its seasonality as the bloom mostly observed during the pre-monsoon season. Among the nutrients, silicate is identified as a major factor controlling the bloom of A. glacialis. The present study highlights the introduction of biogenic silica attributed to precipitation induced land runoff and the effect of wind as important environmental factors responsible for A. glacialis proliferation in nearshore waters of east coast of India.

1990年孟加拉湾西海岸硅藻Asterionellopsis glacialis (Castracane) Round 1990频繁开花环境因素的初步研究

在季风前时期(2018 年 5 月)对印度东海岸冲浪区的 Asterionellopsis glacialis (Castracane) 1990 年盛开和相关的物理化学参数进行了时间序列观测。本研究还回顾了作为冲浪带硅藻的物种状态及其时间特征。参考较早的研究,由于开花群落的改变,A. glacialis 开花在印度环境中的时间特征可以归类为“散发性”,也可以进一步研究其季节性,因为开花主要发生在季风前季节。在养分中,硅酸盐被确定为控制 A. glacialis 开花的主要因素。
