The National Data Buoy Center (NDBC) established the Coastal-Marine Automated Network (C-MAN) for the National Weather Service in the early 1980's. NDBC has installed approximately 50 C-MAN stations on lighthouses, at capes and beaches, on near shore islands, and on offshore platforms. NDBC has deployed over 100 moored (a.k.a., weather) buoys in coastal and offshore waters from the western Atlantic to the Pacific Ocean around Hawaii, and from the Bering Sea to the South Pacific. C-MAN and moored buoy data typically include barometric pressure, wind direction, speed and gust, and air temperature; however, some C-MAN stations are equipped to also measure seawater temperature, water level, waves, and relative humidity. Moored buoys measure wave energy spectra from which NDBC derives significant wave height, dominant wave period, and average wave period. In addition, many moored buoys measure the direction of wave propagation. In collaboration, NDBC and the National Oceanographic Data Center (NODC) are archiving these data from C-MAN and moored buoys. This NODC Accession is part of the collaboration and it contains netCDF (version 4) files with the data collected during December 2011.

XBT data were collected from the KNORR in support of the Integrated Global Ocean Services System (IGOSS). Data were collected by Woods Hole Oceanographic Institution (WHOI) from 14 October 1973 to 08 November 1973. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

This data set, 2 of 5 archived at the NODC, contains digital orthophotography. The data set presents information that represented conditions for the specified Digital Orthophoto Quarter Quads (DOQQ) regions of interest as specified by PhotoScience Task No. 01012C0053 for coastal areas of South Carolina. The project area was selected specifically to cover those sections of the South Carolina coastal critical zone where oysters had historically been mapped by SC Department of Natural Resources, Marine Division. Additional data from this collection is archived at the NODC under accession numbers 0084621, 0084750, 0084751, 0084752. The extent of the DOQQs for the project area ranges from the Hilton Head area in the southern part of South Carolina to the Myrtle Beach area in the northern part of the state. The digital orthophotos in this series have a theoretical ground resolution of 0.25 meter. The digital orthophotos are 4-band in nature (red, green, blue, near infrared) and are delivered as flown in four-band .img file format with associated .png, .jpg, and indexing files. The four-band imagery is delivered in mosaics equaling one eighth of a DOQ. All data were captured during specific imaging windows per contract. The total DOQQ area is approximately 1,527 square miles.

Multibeam backscatter imagery extracted from gridded bathymetry of Maro Reef, Northwestern Hawaiian Islands, USA. These data provide coverage between 20 and 5000 meters. The backscatter dataset includes data collected using Simrad EM300, Simrad EM3002d, Simrad EM120, and Reson 8101 multibeam sonars. The sonars frequencies are 30 kHz, 300 kHz, 12 kHz, and 240 kHz respectively and the backscatter data from each sonar are processed and gridded separately. These metadata are for the 1 m grid cell size Reson 8101 multibeam backscatter data only.

Bathythermograph data were collected from the MUNRO within a 1-mile radius of Ocean Weather Station D (4400N 04100W) and in transit. Data were collected by the United States Coast Guard from 17 July 1972 to 17 August 1972. The platform was equipped and staffed to observe weather and sea conditions. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT file format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

Wave spectra, meteorological, and other data were collected from FIXED PLATFORMS. Data were collected by the National Ocean Service (NOS) from 26 October 1982 to 06 December 1982. Data has been processed by NODC to the standard NODC F191-Meteorology and Wave Spectra format. Data in this accession do not completely conform to the F191 format. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov/. 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.

This dataset contains a unified GeoTiff with 50x50 meter cell size representing the slope of the Charleston Bump off of the South Atlantic Bight, derived from singlebeam SoNar data collected in 2000 by the NOAA Ship Whiting. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with the South Carolina Department of Natural Resources, as well as the NOAA Ship Whiting, and private sector partners, acquired singlebeam bathymetry data off the Charleston Bump from 03/25/2000 to 03/28/2000. Data was acquired with a hull-mounted Kongsberg Simrad Singlebeam echosounder. It was processed by interpolating a bathymetrical surface from feature class points using the spatial analyst natural neighbor tool with 9 neighbor cell radius. The raster surface was exported as a 50m GeoTiff and the slope was derived by using the ESRI ArcMap10 Spatial Analyst Slope tool.
