Physical, meteorological, wave spectra, and other data from CTD casts and current meters aboard NOAA Ship McARTHUR in the Columbia River (Wash./Oregon) from 1981-05-06 to 1981-11-25 (NODC Accession 8300033)

Physical, meteorological, wave spectra, and other data were collected from CTD casts and current meters from NOAA Ship McARTHUR and other platforms in the Columbia River (Wash./Oregon). Data were collected by the National Ocean Service (NOS) from 06 May 1981 to 25 November 1981. Data were processed by NODC to the NODC standard F022-High-Resolution CTD/STD Output and the F191-Meteorology and Wave Spectra formats. Full format and format code descriptions are available at http://www.nodc.noaa.gov/General/NODC-datafmts.html.

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.

The F191 format is used to report meteorological data and ocean wave spectra data from NDBO. The format contains seven data record types to: 1) identify the buoy for position, duration, rate of sampling and heading, 2) identify the meteorological parameters, (temperature, pressure, weather, solar radiation, and surface waves), and 3) report time times series frequency, density and resolution of waves. Each record is 120 character in length, sorted by station and record type.

本数据集涵盖物理、气象、波谱等多类数据，采集自哥伦比亚河（华盛顿州/俄勒冈州段）内CTD（conductivity-temperature-depth，电导率-温度-深度）测次与海流计的观测结果，数据来源包括NOAA舰麦克阿瑟号（NOAA Ship McARTHUR）及其他观测平台。上述数据由美国国家海洋服务局（National Ocean Service, NOS）于1981年5月6日至1981年11月25日期间采集完成，后由美国国家海洋数据中心（National Oceanographic Data Center, NODC）按照NODC标准格式F022-高分辨率CTD/STD输出格式与F191-气象与波谱格式进行标准化处理。完整格式及格式代码说明可通过网址http://www.nodc.noaa.gov/General/NODC-datafmts.html查询获取。

F022格式包含通过CTD（conductivity-temperature-depth，电导率-温度-深度）与STD（salinity-temperature-depth，盐度-温度-深度）仪器采集的高分辨率观测数据。当此类电子设备在海洋中布放并回收时，可连续获取温度、盐度及其他参数的剖面观测序列。数据值可经过平均、滤波处理，或通过插值方法生成，也可按照细至1米的深度间隔进行上报。每个测站均需记录航次与仪器信息、站位坐标、观测日期、时间及采样间隔。测次作业时刻的环境数据（含气象与海面状况）也可一并上报。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），以及可能包含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上报，同时附带文本记录用于填写备注信息。

F191格式用于上报来自NDBO的气象数据与海洋波谱数据。该格式包含7类数据记录，分别用于：1）标识浮标的站位信息、观测时长、采样频率与航向；2）记录各类气象参数（含温度、气压、天气状况、太阳辐射及海面波浪）；3）上报波浪的时间序列、频率、密度与分辨率。每条记录长度为120字符，数据将按照测站与记录类型进行排序。
