Physical, meteorological, and other data from surface sensors, bottle casts, and CTD casts in the Gulf of Alaska from the ACONA as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 09 April 1977 to 10 April 1977 (NODC Accession 7700680)

Physical, meteorological, and other data were collected from surface sensors, bottle casts, and CTD casts in the Gulf of Alaska from the ACONA. 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 09 April 1977 to 10 April 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.本数据集涵盖从阿拉斯加湾ACONA项目中获取的物理、气象及其他相关数据，数据采集方式包括表面传感器观测、采水瓶采样与CTD（Conductivity-Temperature-Depth，电导率-温度-深度）剖面采样。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1977年4月9日至1977年4月10日期间采集，作为外大陆架环境评估计划（OCSEAP）的组成部分。数据经国家海洋数据中心（National Oceanographic Data Center，NODC）处理，采用NODC标准F022高分辨率CTD/STD（Salinity-Temperature-Depth，盐度-温度-深度）输出格式。完整的格式说明可通过NODC官网https://www.nodc.noaa.gov/General/NODC-Archive/f022.html查阅。本入藏数据集的模拟文件可通过NODC用户服务渠道获取。 F022格式包含采用CTD与STD仪器采集的高分辨率数据。这类电子设备在海洋中下放与回收的过程中，可输出温度、盐度及其他参数的近乎连续剖面数据。数据值可经过平均、滤波处理，或通过插值方式生成，也可按照精度最高达1米的深度间隔进行记录。每个采样站位均会记录航次与仪器信息、站位坐标、日期、时间及采样间隔。采样下放时刻的环境数据（气象与海面状况）也可同步记录。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）数据，以及可能存在的溶解氧或透射率数据。数据可按照等间距或不等间距的深度或压力间隔进行存储。附带文本记录可用于填写相关注释。
