Fish survey, fishing duration, and other data from beach seines and other gear from the MARYSVILLE as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 26 June 1984 to 28 July 1985 (NODC Accession 8600252)

Fish survey, fishing duration, and other data were collected from beach seines and other gear from the MARYSVILLE from 26 June 1984 to 28 July 1985. Data were collected by Dames and Moore, Inc. as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC F123 Fish/Shellfish Surveys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f123.html. An analog file for this accession is available from NODC user services.

The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comment.

1984年6月26日至1985年7月28日期间，调查团队从“MARYSVILLE”号作业平台的岸曳网及其他渔具中采集了鱼类调查、捕捞时长及其他相关数据。该数据由戴姆斯与摩尔公司（Dames and Moore, Inc.）作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分开展采集工作。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理，转换为NODC F123鱼类/贝类调查数据集格式。完整的格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f123.html获取。本入藏数据集的模拟文件可通过NODC用户服务渠道获取。

F123格式专为海洋鱼类与贝类的野外采样数据设计。此类数据源于对中层拖网或底拖网渔获物的分析，可提供种群密度与分布相关信息。每份调查记录均包含航次信息、作业位置、日期、时间、渔具类型、作业距离与时长以及拖网次数。环境数据可涵盖气象条件、表层与底层水温及盐度、海流方向与流速等参数。同时还将记录底拖网或其他渔具的尺寸与性能特征。渔获统计信息（如总重量、体积、单位体积鱼类数量等）可分别按单次拖网总渔获量及单个物种进行统计。此外，数据集还可包含选定样本的生物学特征、捕食者/猎物相关信息（源自胃容物分析）以及生长数据。本数据集附带可供注释的文本记录。
