Physical and other data from bottle and CTD casts in the Bering Sea from the OCEANOGRAPHER as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 31 December 1974 to 13 February 1975 (NODC Accession 7601551)

Physical and other data were collected from bottle and CTD casts in the Bering Sea from the OCEANOGRAPHER. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 31 December 1974 to 13 February 1975. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output Format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f022.html. An analog file for this accession is available from NODC user services.

The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

本数据集的物理及其他相关数据采集自"OCEANOGRAPHER"号科考船于白令海开展的采水器与CTD（Conductivity-Temperature-Depth）施放作业。数据由阿拉斯加大学费尔班克斯分校海洋科学研究所（UAK/IMS）于1974年12月31日至1975年2月13日期间采集，作为外大陆架环境评估计划（OCSEAP）的一部分。数据经美国国家海洋数据中心（National Oceanographic Data Center, NODC）处理，符合NODC标准F022高分辨率CTD/STD（Salinity-Temperature-Depth）输出格式。完整格式说明可通过NODC官网www.nodc.noaa.gov/General/NODC-Archive/f022.html获取。本次入库数据的模拟文件可通过NODC用户服务渠道获取。

F022格式包含通过CTD与STD仪器采集的高分辨率数据。此类电子设备在水下布放与回收过程中，可获取温度、盐度及其他参数的准连续剖面数据。数据值可经过平均、滤波处理或通过插值得到，其输出深度间隔可精细至1米。每个站位均记录有航次与仪器信息、站位坐标、日期、时间及采样间隔。施放作业时的环境数据（气象与海面状况）亦可一并记录。数据记录包含指定深度或压力层级下的温度、盐度或电导率、密度（计算得到的sigma-t），以及可能存在的溶解氧或透射率数据。数据可按等间距或不等间距的深度或压力间隔输出。此外，还提供文本记录用于添加注释说明。
