中国第38次南极科学考察(2021-2022年)罗斯海磷虾生物学观测数据

南极磷虾指广泛分布在南大洋水域内的一类海洋浮游高等甲壳动物，是南大洋生态系统中的关键物种，南极磷虾的资源变动直接关乎南大洋生态系统的健康和稳定，掌握南极磷虾资源状况将有助于对整个南大洋生态系统在全球气候变化背景下的响应研究有重要意义。
本数据为中国第38次南极科学考察罗斯海生物学拖网取样数据。
1.数据内容
数据包含内业测量数据，包含各站位磷虾种类数据以及获取的南极磷虾的生物学信息，生物学信息具体包括：体长、体重、头胸甲长的情况。根据CCAMLR采样要求，每网样品不同种类的磷虾至少测量100尾磷虾数据，不足100尾则全部进行测量。相关数据可用于后续南极磷虾资源评估及南极磷虾种群结构分析研究。

Antarctic krill refers to a group of marine pelagic higher crustaceans widely distributed in the waters of the Southern Ocean, and is a keystone species in the Southern Ocean ecosystem. Fluctuations in Antarctic krill resources directly affect the health and stability of the Southern Ocean ecosystem. Mastering the status of Antarctic krill resources is of great significance for research on the response of the entire Southern Ocean ecosystem under the context of global climate change.

This dataset is the biological trawl sampling data collected during the 38th Chinese National Antarctic Research Expedition in the Ross Sea.

1. Data Content
The dataset includes laboratory measurement data, covering krill species data from each station and biological information of collected Antarctic krill. The biological information specifically includes body length, body weight and carapace length. Per CCAMLR sampling requirements, at least 100 individuals of each krill species per trawl sample shall be measured; if the total number of individuals is less than 100, all individuals shall be measured. The relevant data can be used for subsequent studies on Antarctic krill resource assessment and population structure analysis.
