Physical, meteorological, and other data from surface sensors and CTD casts in the Beaufort Sea from helicopters as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 20 February 1976 to 29 February 1976 (NODC Accession 7601640)

Physical, meteorological, and other data were collected from surface sensors and CTD casts in the Beaufort Sea from helicopters. Data were collected by the University of Washington - Seattle (UW) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 20 February 1976 to 29 February 1976. 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.本数据集包含通过直升机搭载的海面传感器与CTD（conductivity-temperature-depth，电导率-温度-深度）剖面仪在波弗特海采集得到的物理、气象及其他相关数据。数据采集工作由西雅图华盛顿大学（University of Washington-Seattle, UW）主导，作为外大陆架环境评估计划（Outer Continental Shelf Environmental Assessment Program, OCSEAP）的组成部分，实施时段为1976年2月20日至1976年2月29日。后续由国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准F022高分辨率CTD/STD输出格式完成数据处理。该格式的完整说明文档可通过NODC官网链接https://www.nodc.noaa.gov/General/NODC-Archive/f022.html查阅，本数据集的模拟文件可向NODC用户服务部门申请获取。 F022格式存储了通过CTD与STD（salinity-temperature-depth，盐度-温度-深度）仪器采集的高分辨率海洋数据。当此类电子设备在海洋中布放并回收时，可连续获取温度、盐度及其他相关参数的剖面序列。数据值可经过平均、滤波处理，或通过插值方式生成，其报告的深度间隔最小可精确至1米。每个测站均附带航次与仪器信息、站位坐标、采集日期、时间及采样间隔等元数据。此外还可包含CTD剖面作业时刻的环境数据，如气象与海面状态信息。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/压力间隔进行报告。数据集同时附带文本记录用于备注说明。
