ADF&G Prince William Sound Salmon Aerial Survey Data, 1948-2018

Data in this collection include counts of salmon in Prince William Sound (PWS) streams (including bay, mouth and stream counts) 1948-2018. Data were generated from visual counts of salmon from airplane-based observers during low-level flyovers. Data were collected as part of ADF&G efforts to estimate salmon escapement by stream for management of commercial fisheries. Data are presented as CSV files that contain bay, mouth, and stream counts for each species and survey stream by day. Data include other observations including environmental conditions and presence of bears.

本数据集收录了1948年至2018年间阿拉斯加威廉王子湾（Prince William Sound，PWS）各溪流（涵盖海湾、入海口及溪流本体的计数范畴）的鲑鱼种群数量统计数据。该数据由低空飞越作业期间的机载观测员通过目视计数方式获取所得，是阿拉斯加鱼类与狩猎部（Alaska Department of Fish and Game，ADF&G）为估算各溪流的鲑鱼逃逸量以支撑商业渔业管理所推进工作的一部分成果。数据集以CSV文件形式呈现，其中按日记录了各物种类群、调查溪流对应的海湾、入海口及溪流的鲑鱼计数数据，同时还包含环境条件、熊类活动踪迹等其他观测信息。
