Description

The Integrated Science Data Management (ISDM) office processes oceanographic profiles reported for the world oceans in near real-time from the Global Telecommunications System (GTS) for the Global Temperature and Salinity Profile Program (GTSPP). These data also support the activities of the Ship-of-Opportunity Programme Implementation Panel (SOOPIP) and the WOCE Upper Ocean Thermal Program (WOCE UOT).

Description

This data set contains sensitive biological resource data for waterfowl, seabirds, gulls and terns for the North Slope of Alaska. Vector points in this data set represent bird nesting sites. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for North Slope, Alaska. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the BIRDS (Bird Polygons) data layer, part of the larger North Slope, Alaska ESI database, for additional bird information.

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.

Description

Point-count surveys at 50-cm intervals were conducted along 2 consecutively placed, 25m line transect lines, as part of Rapid Ecological Assessments conducted at 11 sites around Kingman Reef in Pacific Remote Island Areas from 4 April to 7 April 2008, aboard the NOAA ship Hi'ialakai during the Reef Assessment and Monitoring Program (RAMP) Cruise HI0803. Raw survey data consisted of counts of benthic elements, including but not limited to live coral, dead coral, carbonate pavement, sand, coral rubble, fleshy macroalgae, crustose coralline algae, turfalgae, as well as other sessile invertebrates along the two transects. All live benthic elements were identified to the lowest taxonomic level possible. These data provide the basis for computing quantitative estimates of percent live coral cover, as well as percent cover of the different benthic constituents.

Description

Autonomous underwater vehicles (AUVs) are increasingly being used to collect physical, chemical, and biological information in the marine environment. Recent efforts have been made to merge AUV technology with acoustic telemetry to provide information on the distribution and movements of marine fish. During 2010, we conducted a study in coastal waters near Juneau, Alaska to determine the feasibility of using AUVs to locate marine species under rigorous field conditions, and to compare this approach with traditional vessel-based tracking. Tracking surveys were conducted with a REMUS 100 AUV equipped with an integrated acoustic receiver and hydrophone. The AUV was programmed to navigate along predetermined routes to detect acoustic transmitters within the area. Comparable surveys were conducted with a boat equipped with acoustic tracking gear. Moorings with transmitters at 20-500 m were deployed to provide acoustic targets at known locations and depths. Marine fishes and crabs were tagged to provide mobile targets. Transmitter depth had a major impact on tracking performance. The AUV was equally effective or better detecting reference transmitters in shallow water, and significantly better than the boat for transmitters at deeper depths. Similar results were observed for the tagged animals. Crabs at moderate depths were recorded by both tracking methods, while only the AUV detected fish at depths exceeding 500 m. The AUV periodically had difficulty navigating and maintaining course due to the strong currents and extreme depths in the area. AUVs with greater cruising speeds, increased operating depths, and improved navigation would enhance AUV performance in marine environments.

Description

The object was to probe in greater detail than has been possible in the past, the dynamical balances of Gulf Stream meanders and their change with time. Specifically, by repeatedly surveying a meander with a variety of measurement techniques, we hope to reconstruct the density and velocity fields with sufficient accuracy to quantify the fluxes of mass, momentum and voricity through the meander and how these affect the structure of the meander during the observation period.

Summary

Description

This dataset contains a unified ESRI Grid with 10 meter cell size representing the slope (degrees) of selected portions of seafloor around Abrir La Sierra Bank, Bajo De Cico, and Isla De Mona, derived from data collected in 2007. 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 Reson 8124 (200 kHz) multibeam echosounder (for shallow areas of Abrir La Sierra Bank only) and with a hull-mounted Kongsberg Simrad EM 1002 (95 kHz) multibeam echosounder (for all other areas). 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.
