1982-1983渤海海洋环境海洋生物数据集

本数据集是自1982年6月至1983年11月，在渤海共设76站（其中辽东湾24站，渤海湾31站，莱州湾21站，渤海中部33站），逐月进行包括微型浮游生物在内的浮游植物现存量（浮游植物叶绿素a含量）和中、小型浮游植物个体数量变动的调查。春季以渤海南部（包括渤海湾和莱州湾）的鱼、虾类产卵场和育幼场为主要调查区，其余月份还调查了辽东湾，渤海中部调查的次数较少。并对浮游植物现存量（叶绿素a含量）的平面分布、季节变化，浮游植物个体数量动态及优势种的季节演替等进行了分析、研究和总结。

This dataset is derived from monthly surveys conducted in the Bohai Sea from June 1982 to November 1983, with a total of 76 sampling stations (24 in Liaodong Bay, 31 in Bohai Bay, 21 in Laizhou Bay, and 33 in the central Bohai Sea). The surveys targeted the standing stock of phytoplankton (including microphytoplankton) as indicated by chlorophyll a concentration, as well as the abundance fluctuations of meso- and small-sized phytoplankton. In spring, the primary survey region was the spawning and nursery grounds of fish and shrimp in the southern Bohai Sea (encompassing Bohai Bay and Laizhou Bay); surveys were also implemented in Liaodong Bay during other months, while the central Bohai Sea was surveyed less frequently. Additional analyses, research and summaries were performed on the horizontal distribution and seasonal variation of phytoplankton standing stock (chlorophyll a concentration), the abundance dynamics of phytoplankton, and the seasonal succession of dominant phytoplankton species.
