This data set contains time series measurements of ocean currents. These data are obtained from current meter moorings and represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth and meter characteristics are reported for each station. The data record includes values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north. Data values may be subject to averaging or filtering and are typically reported at 10 - 15 minute time intervals. Water temperature, pressure and conductivity or salinity may also be reported. A text record is available for optional comments.

Data has been processed by NODC to the NODC standard Wave/Current Observations (F181) format. The F181 format is designed to support studies made by automated ocean sensoring devices. The format consists of ten record types. Record types A and B describe the basic environmental information to understand the data. Record types C, D, E, F, G, H, I, and J are used to report current meter, water level, pressure gauge, wave height, and wave direction, spectra, fourier coefficients, and current meter respectively.

This data set contains time series measurements of seawater pressure from anchored or bottom-mounted sensors. Measurements of variations at depth of seawater pressure provide information on tidal and storm flows, ocean circulation and other phenomena that cause changes in sea surface elevation or slope and that can be detected from their pressure signature. Position, bottom depth and gauge depth are reported for each station. The data record comprises values of total pressure at specified date and time. Data values may be subject to averaging or filtering and are typically reported at time intervals of 10 - 15 minutes. Seawater temperature may also be reported. Comments may be reported in a text record.

Current meter - direction and other data were collected from FIXED PLATFORMS from 10 May 1976 to 19 June 1976. Data were collected by the National Ocean Service (NOS) and were processed by NODC to the NODC standard F005 - Current Meter Data (Resultants) format. 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.

This dataset contains physical-chemical oceanographic data recorded at discrete depth levels, in NODC Standard Oceanographic Station Data (SD2 or C100) format. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity- temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters are temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels.

Current meter - direction and other data were collected from FIXED PLATFORMS. Data were collected by the National Ocean Service (NOS) from 27 June 1972 to 10 October 1972. Data were processed by NODC to the NODC standard F005 - Current Meter Data (Resultants) format. 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.).

This data set contains time series coastal ocean wave and current data collected during the Atlantic Remote Sensing Land/Ocean Experiment (ARSLOE). ARSLOE was sponsored jointly by the Coastal Engineering Research Center (CERC) of the US Army Corps of Engineers and the National Ocean Survey (now Service) of NOAA; it was conducted from 6 October to 30 November 1980 in the area off Duck, NC, near the CERC Field Research Facility. The data were collected using modern electronic sensors such as EM current meters, waveriders, wave staffs and pressure gauges. Each series of measurements may include instrument type and characteristics, position, mean sea level, initial time, time span of the data sample and sampling period. Depending on the type of instrument used and data collected, data are reported in eight alternate data records. These contain: 1) EM current meter data (east and north components); 2) Baylor gauge data (water level); 3) pressure gauge data (water pressure); 4) waverider data (wave displacement); 5) wave direction buoy (wave displacement, east and north wave slope components); 6) wave spectra (co- and quadspectra); 7) wave data (angular Fourier coefficients); and 8) three-axis current meter data (east and north components). A text record is available for providing additional documentation.
