Description

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 contains the 1946-era and 2005-era classifications of Rota, Commonwealth of the Northern Mariana Islands and can be used to analyze change. This data set utilized Scanned Black and White Aerial Photography and Quickbird scenes which were analyzed according to the Coastal Change Analysis Program (C-CAP) protocol to determine land cover.

This dataset contains a comma-delimited ASCII XYZ text file with easting, northing, and depth in meters values for the bathymetry of Bajo De Cico, Puerto Rico. XYZ values are derived from a 3 m resolution gridding process. NOAA's NOS/NCCOS/CCMA Biogeography Team, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 4/14/07 to 4/24/07. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 (95 kHz) multibeam echosounder. It was processed by a NOAA contractor using CARIS HIPS software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides and zoning from NOAA COOPS. Data is in UTM zone 19 north, datum NAD83. The processed CARIS data was used to generate a CARIS BASE surface based on swath angle. An ASCII XYZ file was exported from the BASE surface and opened in ESRI ArcMap 9.x using an XYZ to raster tool. The project was conducted to meet IHO Order 1 and 2 accuracy standards, dependant on the project area and depth. All users should individually evaluate the suitability of this data according to their own needs and standards.

Fish larvae counts and standardized counts for larvae captured in CalCOFI icthyoplankton nets (primarily vertical [Calvet or Pairovet], oblique [bongo or ring nets], and surface tows [Manta nets]). Surface tows are normally standardized to count per 1,000 m3 strained. Oblique tows are normally standardized to count per 10 m2 of surface sampled. This table includes all tows by species, even if zero larvae were captured for the species, i.e., negative tows. The "Larvae Counts Positive Tows" table includes only tows where one or more larvae were captured for the species selected by the user.

Description

Integrated acoustic and trawl surveys are used to assess the distribution, biomass, and biology of Pacific hake along the Pacific coasts of the United States and Canada. Scientists from the Northwest Fisheries Science Center (NWFSC) and Department of Fisheries and Oceans-Canada are responsible for conducting the survey. The survey consists of a series of transects that are oriented generally east-west, and are spaced at a nominal 10-nautical mile interval. Sea depth at the nearshore end of individual transects is typically 50 m; offshore extents are typically at a depth of 1,500 m. Geographical coverage extends from near Morro Bay, CA north to Dixon Entrance. Acoustic data are collected during daylight hours with a Simrad EK60 scientific echo sounder coupled with the ER60 software system. Trawl samples from pelagic and bottom trawls are used to classify the observed backscatter layers to species and size composition and to collect specimens of Pacific hake and other organisms. Analysis of acoustic data involves identification and delineation of backscatter layers that are attributed to Pacific hake. The biomass estimate and length-at-age composition of Pacific hake generated from this survey are used in analysis and management of the stock. This survey is conducted on a biennial basis. There is a firm deadline for producing the biomass estimate in the middle of the December following the survey. Raw acoustic backscatter (ER 60.raw) and Echolog 60 (Echoview.ek6) data files are logged.

Benthic habitat maps of the nearshore marine environment of St. John, U.S. Virgin Islands were created by visual interpretation of remotely sensed imagery. The objective of this effort, conducted by NOAA's Center for Coastal Monitoring and Assessment - Biogeography Branch in partnership with the U.S. National Park Service (NPS), was to provide spatially-explicit information on the habitat types, biological cover and live coral cover of St. John's coral reef ecosystem. One-meter panchromatic and four-meter multi-spectral data from the IKONOS satellite sensor were purchased for the mapping area. Photo-interpreters accurately and reliably delineated boundaries of features from this IKONOS imagery as they appeared on the computer monitor using a software interface.

XBT data were collected from the NOAA ship Researcher in support of the Integrated Global Ocean Services System (IGOSS) project. Data were collected by the US DOC; NOAA; National Ocean Service - Miami from 28 October 1973 to 11 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.

Oceanographic station data were collected from the JARVIS within a 1-mile radius of Ocean Weather Station N (3000N 14000W) and in transit. Data were collected by the United States Coast Guard (USCG) from 17 June 1973 to 05 July 1973. Data were processed by NODC to the NODC standard Station Data II Output Format (SD2). Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/sd2.html. The SD2 format contains physical-chemical oceanographic data recorded at discrete depth levels. 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 and 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.
