Current direction, wind wave spectra, and CTD data from moored current meter and CTD casts in the North Atlantic Ocean from 1982-09-15 to 1983-09-15 (NODC Accession 8500148)

Current direction, wind wave spectra, and CTD data were collected using moored current meter and CTD casts in the Gulf of Mexico from September 3, 1982 to September 15, 1983. Data were submitted by National Ocean Service (NOS). Data has been been processed by NODC to the standard NODC standard F005- Current Meter Data, F022- CTD High Resolutions, and F191- Wave Wind Spectra formats. Full format and format code descriptions are available at http://www.nodc.noaa.gov/General/NODC-datafmts.html.

The F005 format is used for time series measurements of ocean currents obtained using moored current-measuring instruments, principally Aanderaa current meters (manufactured by Aanderaa Instruments Inc.). These data represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed mooring point and measure flow past the sensor. Position, water depth, and sensor depth are reported for each station. The data record comprises values of current direction and speed at specified date and time. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Other environmental parameters may also be reported. These include: water temperature, salinity, conductivity, and transmissivity; wind direction and speed; and dominant wave direction, height, and period. A text field is available for optional comments.

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). 3) Report time series frequency, density and resolution of waves. Each record is 120 characters in length, sorted by station and record type. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (column 4-9). The file identifier, to be assigned by the orignator, is a unqiue originator id for each data submission. After submission, the NODC reassigns to this field an unqiue NODC identifier.

1982年9月3日至1983年9月15日期间，研究人员于墨西哥湾通过锚定海流计与CTD（Conductivity-Temperature-Depth，电导-温度-深度仪）采集获取了海流方向、风浪谱以及CTD数据。该数据集由美国国家海洋服务局（National Ocean Service, NOS）提交，美国国家海洋数据中心（National Oceanographic Data Center, NODC）已将数据处理为标准格式：F005-海流计数据、F022-高分辨率CTD数据以及F191-风浪谱数据。完整格式与格式代码说明可查阅http://www.nodc.noaa.gov/General/NODC-datafmts.html。

F005格式用于锚定海流测量仪器获取的海流时间序列数据，主流设备为安德拉仪器公司（Aanderaa Instruments Inc.）生产的安德拉海流计。此类数据采用欧拉海流测量方法：将仪器部署于固定锚点，测量流经传感器的流体流速与流向。每个测站均记录站位位置、水深以及传感器布设深度。数据记录包含指定日期与时间下的海流方向与流速数值。数据值可经过平均或滤波处理，通常以10至15分钟为时间间隔上报。此外还可上报其他环境参数，包括水温、盐度、电导率、透射率；风向与风速；以及主波向、波高与波周期。数据中预留文本字段用于填写可选备注。

F022格式包含通过CTD（Conductivity-Temperature-Depth，电导-温度-深度仪）与STD（Salinity-Temperature-Depth，盐度-温度-深度仪）采集的高分辨率数据。这类电子设备在海洋中升降作业时，可获取温度、盐度及其他参数的近乎连续的剖面数据。数据值可经过平均、滤波处理，或通过插值获得，通常可实现最高1米的精细深度间隔上报。每个测站均记录航次与仪器信息、站位位置、日期、时间以及采样间隔。同时可上报采水时的环境数据（气象与海面状态）。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，即密度距平），以及可能存在的溶解氧或透射率数值。数据可按等间距或不等间距的深度或压力间隔上报。数据中预留文本记录字段用于填写备注。

F191格式用于上报来自NDBO的气象数据与海浪谱数据。该格式包含七种数据记录类型：1) 标识浮标的位置、观测时长、采样速率与航向；2) 标识气象参数（气温、气压、天气状况、太阳辐射与海面波浪）；3) 上报海浪的时间序列频率、密度与分辨率。每条记录长度为120字符，按测站与记录类型排序。所有记录的前九列用于填写文件类型（第1至3列）与文件标识符（第4至9列）。文件标识符由数据提交方指定，为每份数据提交的唯一提交方标识。数据提交后，美国国家海洋数据中心（NODC）会将该字段重新分配为唯一的NODC内部标识。
