Physical, meteorological, and other data from surface sensors, bottle casts, and CTD casts in the Bering Sea from the SURVEYOR as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 17 April 1977 to 01 May 1977 (NODC Accession 7800310)

Physical, meteorological, and other data were collected from surface sensors, bottle casts, and CTD casts in the Bering Sea from the SURVEYOR. Data were collected by the University of Alaska as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 17 April 1977 to 01 May 1977. 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.

本数据集包含在白令海通过“勘探者号”（SURVEYOR）调查船搭载的表层传感器、采水器站位采样及CTD（conductivity-temperature-depth，电导率-温度-深度仪）站位采样获取的物理、气象及其他相关数据，由阿拉斯加大学作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的一部分，于1977年4月17日至5月1日期间采集完成。数据由国家海洋数据中心（NODC）按照其官方标准F022高分辨率CTD/STD输出格式进行标准化处理。完整的格式说明文档可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f022.html查阅。本次入库数据集的模拟文件可通过NODC用户服务渠道获取。

F022格式收录了通过CTD（conductivity-temperature-depth，电导率-温度-深度仪）与STD（salinity-temperature-depth，盐度-温度-深度仪）设备采集的高分辨率数据。此类电子设备在海洋中下放与回收的过程中，可近乎连续地输出温度、盐度及其他相关参数的剖面观测数据。数据值可经过平均、滤波处理，或通过插值方式生成，也可按精度最高达1米的深度间隔进行记录报告。每个采样站位均会记录航次与仪器信息、站位地理坐标、观测日期、时间及采样间隔。采样作业时刻的环境数据（包括气象及海表状态）亦可一并收录至数据集中。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σ-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/压力间隔进行记录报告。另有专用文本记录可供附加注释说明。
