CSIRO, North West Shelf Demersal Marine Resources Study 1980-1997

The North West Shelf study was set up to examine the population dynamics and biology of demersal marine resources of the North West Shelf of Australia, in relation to their physical, chemical and biological environment. The first phase of the study comprised 10 cruises by the vessel Soela between 1982 and 1984 to investigate aspects of the ecosystem, followed by an experimental management phase from 1985 to 1992 during which parts of the fishery were closed and the resulting changes monitored. Data gathered during the study included the distribution, reproduction, diet, growth and mortality of the shelf ecosystem biota as well as information about the water column, sediments, and bottom environment. Over 1000 different fish species were recorded during the course of the study. Return cruises to the North West Shelf were made annually from 1986 to 1991 and also in 1995 and 1997. This data has been republished (2022-09-05 with additional details of each occurrence where they can be one of three types: catch composition (counts per taxa and optional aggregated weights by trawl event), catch measurements (length and/or weight) of individual taxa and/or catch specimens and their stored location. The occurrence type is recorded in occurrenceremarks.

澳大利亚西北陆架（North West Shelf）研究项目旨在探究澳大利亚西北陆架海域底层海洋生物资源的种群动态与生物学特征，及其与物理、化学和生物环境的关联。本研究第一阶段为1982年至1984年间由"Soela"号科考船执行的10次科考航次，用于探究该生态系统的多个维度；随后在1985年至1992年进入实验性管理阶段，期间对部分渔业区域实施禁捕，并对由此产生的变化进行监测。研究期间收集的数据涵盖该陆架生态系统生物群落的分布、繁殖、食性、生长与死亡率，同时包含水柱、沉积物及底栖环境的相关信息。研究期间共记录到超过1000种不同的鱼类。1986年至1991年每年均会开展西北陆架回访航次，此外1995年与1997年也各执行了一次该类航次。该数据集于2022年9月5日重新发布，补充了每一条采样记录的详细信息。采样记录可分为三类：渔获组成（按分类单元统计的数量，以及拖网作业可选的累计重量）、单个分类单元的渔获测量数据（体长及/或体重），以及渔获标本及其存储位置。采样记录的类型将在occurrenceremarks字段中予以标注。
