Fish length, weight, and abundance data from trawl surveys in the Chukchi Sea, Arctic Marine Biodiversity Observing Network (AMBON) research cruise on the vessel Norseman II from 2015-08-11 to 2015-09-03 (NCEI Accession 0208100)

This dataset contains fish haul and specimen data collected in the Chukchi Sea, U.S. Arctic during the 11 August - 3 September 2015 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. The dataset is one comma separated values (csv) file containing the length, weight, and life stage of the fish collected using a plump-staff beam or Isaacs-Kidd midwater trawl. This dataset was used to derive catch per unit effort (CPUE) by weight and species richness (number of taxa per haul) using analyses generated in the R software environment. The data was transformed from the native format into a table structure using Darwin Core term names as column names.

该数据集包含2015年8月11日至9月3日期间，在美国北极楚科奇海（Chukchi Sea）开展的北极海洋生物多样性观测网络（AMBON）科考航次中采集的渔获与样本数据。数据集为一个逗号分隔值（comma separated values, csv）文件，记录了通过粗杆桁杆拖网（plump-staff beam）或艾萨克斯-基德中层拖网（Isaacs-Kidd midwater trawl）捕获鱼类的体长、体重及生活史阶段信息。该数据集用于在R软件环境中进行分析，以推导单位努力渔获量（catch per unit effort, CPUE，按重量计）和物种丰富度（每次渔获的分类单元数量）。数据已从原生格式转换为采用达尔文核心术语（Darwin Core term）命名列名的表格结构。
