Donn�es de chalut du Bell M. Shimada de la NOAA pendant l'exp�dition hivernale en haute mer 2022 de l'Ann�e internationale du saumon dans le Pacifique

This dataset contains the trawl and specimen data collected aboard the R/V Bell M. Shimada for the IYS survey in 2022 in the North Pacific Ocean. This package contains three components; event, catch, and specimen data. The event data contains all of the sampling event information, including time, location, and duration. All dates and times are in UTC. The catch data contains all of the catch records, as counts, weights, and lengths, for each species/taxa at each station. The sampling method for every catch weight should be total weight, and all weights are in kilograms. The specimen data contains individual lengths (in cm) and weights for sampled individuals from each station.

本数据集收录了2022年北太平洋海域IYS调查期间，随"贝尔·M·岛田号"（R/V Bell M. Shimada）科考船采集的拖网数据与标本数据。本数据集包含三个核心组成部分：采样事件数据、渔获数据与标本数据。
采样事件数据涵盖所有采样事件的完整信息，包括时间、位置与持续时长，所有日期及时间均采用协调世界时（UTC）。
渔获数据记录了各站位下每个物种类群（taxa）的渔获信息，具体包括个体数量、体重与体长。所有渔获体重均采用总重量法计量，且体重单位统一为千克。
标本数据包含各站位所采样本个体的体长（单位：厘米）与体重。
