Current direction, benthic organisms, wind wave spectra, and other data from moored current meter casts and other instruments in the Gulf of Mexico during the Brine Disposal project, 12 January 1978 - 01 June 1980 (NODC Accession 8000465)

Current direction, benthic organisms, wind wave spectra, and other data were collected using moored current meter casts and other instruments from the CAPT JACK and GUTS III in the Gulf of Mexico from January 12, 1978 to June 1, 1980. Data were submitted by Texas A&M University as part of the Brine Disposal project. Data has been been processed by NODC to the NODC standard F005- Current Meter Data, F132- Benthic Organisms, F123- Fish Shellfish Resource, and F191- Wind Wave 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 F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comments. The F132 format contains data from field sampling or surveys of bottom dwelling marine organisms. The data provide information on species abundance, distribution, and biomass; they may have been collected by point sampling (grab or core), by tow (dredge, trawl or net), by photographic surveys, or by other methods. Cruise information such as vessel, start and end dates, investigator, and institution/agency; station numbers, positions and times; and equipment and methods are reported for each survey. Environmental data reported at each sampling site may include meteorological and sea surface conditions; surface and bottom temperature, salinity and dissolved oxygen; and sediment characteristics. Number of individual organisms and total weight of organisms is reported for each species. 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 for internal use.1978年1月12日至1980年6月1日期间，研究团队于墨西哥湾CAPT JACK与GUTS III作业海域，借助锚定海流计投放装置及其他配套仪器，采集了海流方向、底栖生物、风浪谱等相关数据。本次数据由得克萨斯农工大学（Texas A&M University）作为盐水处置项目（Brine Disposal project）的一部分提交。美国国家海洋数据中心（National Oceanographic Data Center，NODC）已将这批数据按照NODC标准格式进行标准化处理，对应格式分别为F005-海流计数据、F132-底栖生物数据、F123-鱼类及贝类资源数据以及F191-风浪谱数据。完整的格式及格式代码说明可通过http://www.nodc.noaa.gov/General/NODC-datafmts.html查阅获取。 F005格式用于存储锚定海流测量仪器获取的海流时间序列数据，该类仪器主要为安德拉仪器公司（Aanderaa Instruments Inc.）生产的Aanderaa海流计。此类数据采用欧拉法进行海流测量，即仪器部署于固定锚点，测量流经传感器的流体运动。每个测站均记录了站位位置、水深及传感器埋设深度。数据记录包含指定日期与时间下的海流方向与流速数值，数据通常经过平均或滤波处理，典型采样间隔为10至15分钟。此外还可记录其他环境参数，包括水温、盐度、电导率、透射率；风向与风速；以及主浪方向、波高与周期。同时预留了文本字段用于填写可选备注。 F123格式用于存储海洋鱼类及贝类的野外采样数据。数据源自中层拖网或底拖网捕捞样本的分析结果，可提供种群密度与分布相关信息。每份调查均记录了航次信息、站位位置、日期与时间、渔具类型、捕捞距离与时长以及拖网次数。环境数据可包含气象条件、表层与底层水温及盐度，以及海流方向与流速。同时还会记录底拖网或其他渔具的尺寸与特性。可提供单次拖网及单个物种的捕捞统计数据（如重量、体积、单位体积鱼类数量）。此外还可收录选定样本的生物学特征、捕食者/猎物相关信息（源自胃容物分析）以及生长数据。预留了文本记录用于填写备注。 F132格式存储了底栖海洋生物的野外采样或调查数据，可提供物种丰度、分布及生物量相关信息。数据采集方式可分为点位采样（抓斗式或岩芯采样）、拖网作业（扒网、拖网或网具）、摄影调查或其他方法。每份调查均记录了航次信息，包括作业船舶名称、起止日期、调查人员以及所属机构/单位；测站编号、位置与时间；以及所用设备与采集方法。每个采样点记录的环境数据可包括气象与海表状况、表层与底层水温、盐度及溶解氧含量，以及沉积物特性。每个物种的个体数量及总生物量均会被记录。预留了文本记录用于填写备注。 F191格式用于存储来自国家数据浮标办公室（National Data Buoy Office，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）浮标信息标识，涵盖位置、采样时长、采样频率与航向；2）气象参数标识，包括气温、气压、天气状况、太阳辐射以及表层海浪；3）报告海浪的时间序列频率、密度与分辨率。每条记录长度为120个字符，按站位与记录类型排序。所有记录的前九列分别用于填写文件类型（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自行设定，为每份数据提交分配唯一的提交方标识。数据提交后，NODC将为该字段重新分配唯一的内部NODC标识符。
