Modified Herring Trawl Fish Catch Data, Gulf of Alaska Fjords, 2004-2011

This dataset contains catch data from trawls at the sampling stations. We deployed a modified herring trawl in coastal waters within glacier fjords of Alaska. Sampling stations in each fjord were chosen randomly from a 2.5 x 2.5 km grid overlaid on navigable waters in the fjord. The number of stations in each fjord was chosen to achieve a sampling frequency of about 1 sample per 15 km^2, and was based on available resources and logistical constraints (weather, navigational hazards and vessel time).

本数据集涵盖采样站位的拖网渔获数据。我们在阿拉斯加冰川峡湾的近岸海域部署了改良型鲱鱼拖网。每个峡湾内的采样站位均从覆盖该峡湾通航水域的2.5×2.5公里网格中随机选取。各峡湾的站位数量以实现约每15平方公里1个样本的采样频率为目标设定，该数量依据可用资源及后勤限制条件（天气、通航危险与船舶作业时长）确定。
