Popis

This data set contains lidar point data (Geodetic Coordinates) from a strip of Southern California coastline (including water, beach, cliffs, and top of cliffs) from Dana Point to Point La Jolla. The data set was created by combining data collected using an Optech Inc. Airborne Laser Terrain Mapper (ALTM) 1225 in combination with geodetic quality Global Positioning System (GPS) airborne and ground-based receivers. The Bureau of Economic Geology, the University of Texas at Austin owns and operates an ALTM 1225 system (serial number 99d118). The system was installed in a twin engine Partenavia P-68 (tail number N6602L) owned and operated by Aspen Helicopter, Inc. The lidar data set described by this document was collected on 28-29 March 2003; Julian Days 08703 and 08803 (see Lineage, Source_Information, Source_Contribution for pass information). Conditions on both days were clear skies, no fog or low clouds. 99d118 instrument settings for these flights were; laser pulse rate: 25kHz, scanner rate: 26Hz, scan angle: +/- 15-20deg, beam divergence: narrow, altitude: 900-1160m AGL, and ground speed: 90-132kts. Two GPS base stations (Scripps pier and Dana Point, see Lineage, Source_Information, Source_Contribution for coordinates) were operating during the survey. Data represented is all points including terrain, vegetation, and structures. This data also contains returns from the water surface. No processing has been done to remove returns from terrain, vegetation, structures or water surfaces.

Popis

This data set contains sensitive biological resource data for threatened/endangered sea turtles in coastal Hawaii. Vector points in this data set represent sea turtle nesting sites, and sea turtle occurrences for species that are considered rare in Hawaii. 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 Hawaii. 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 REPTILES data layer, part of the larger Hawaii ESI database, for additional sea turtle information.

Popis

Environmental Sensitivity Index (ESI) maps are an integral component in oil-spill contingency planning and assessment. They serve as a source of information in the event of an oil spill incident.ESI maps contain three types of information: shoreline habitats (classified according to their sensitivity to oiling), sensitive biological resources, and human-use resources. Most often, this information is plotted on 7.5 minute USGS quadrangles, although in the Alaska ESI maps, USGS topographic maps at scales of 1:63,360 and 1:250,000 are used, and in other ESI maps, NOAA charts have been used as the base map. Collections of these maps, grouped by state or a logical geographic area, are published as ESI atlases. Digital data have been published for most of the U.S. shoreline, including Alaska, Hawaii, and Puerto Rico.

Popis

Meteorological, oceanographic, wave spectra, and other data were collected from FIXED PLATFORMS in the North Atlantic Ocean and other locations. Data were collected by the National Data Buoy Center (NDBC) from 01 February 1992 to 29 February 1992. Data were processed by NODC to the standard NODC F291-Meteorology, Oceanography, and Wave Spectra from Buoys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f291.html. Links to digital data are not available at this time. An analog file is available from NODC user services. The F291 format is used to report meteorological, oceanographic, and wave spectra data from NDBC moored buoys and fixed land stations. The format contains thirteen data record types to: 1) Identify the buoy position and other descriptive information; 2) report the meteorological measurements; 3) report wave energy spectra and wave direction; 4) report subsurface physical, biological and chemical oceanographic measurements; and 5) report detailed information on continuously measured wind speed and direction. Each record is 120 characters in length, sorted by station and record type. Record type is omitted where data defined in that type and not measured. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (columns 4-9). The file identifier, assigned by the originator, is a unique originator id for each data submission. After submission, the NODC reassigns to this field a unique and NODC identifier for internal use.

Popis

This dataset contains a 9m ESRI Grid representing the rugosity of a selected portion of seafloor for Isla de Mona in Puerto Rico, derived from data collected in 2008. Rugosity is defined as the ratio of surface area to planar area and is used as a measure of benthic terrain complexity or "roughness". Rugosity values near 1 represent flat, smooth terrain, while higher values reflect increasing rugosity or terrain roughness. For rugosity grid interpretation, it is recommended that the grid be reclassified according to standard deviation divisions. NOAA's NOS/NCCOS/CCMA Biogeography Branch, in collaboration with NOAA vessel Nancy Foster and territory, federal, and private sector partners, acquired multibeam bathymetry data in Puerto Rico from 2/25/08 to 3/8/08. Data was acquired with a hull-mounted Kongsberg Simrad EM 1002 multibeam echosounder (95 kHz) in 2008. 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 imported to ESRI ArcMap 9.2 using the Convert XYZ to Raster tool developed by CCMA for this purpose. The Benthic Terrain Modeller (BTM) tool, a collection of ArcGIS terrain visualization tools developed by the Oregon State University (OSU) Department of Geosciences and the National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center, was used to calculate the rugosity of that bathymetric grid. More information on the specific algorithms used can be found in the BTM's documentation. 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.

Popis

Line point intercept (LPI) surveys and benthic composition assessments were conducted during Rapid Ecological Assessments (REA) as part of the Pacific Reef Assessment and Monitoring Program (RAMP) cruise HA1201 in American Samoa from 20120401 to 20120426. Surveys are conducted by the Coral Reef Ecosystem Division (CRED) of the NOAA Pacific Islands Fisheries Science Center (PIFSC) at periodic intervals between one and three years to support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems. During the cruise, 22 REA sites were surveyed at Tutuila in American Samoa. Benthic biologists from NOAA's Coral Reef Ecosystem Division conducted Line Point Intercept surveys to quantitatively document the benthic cover at pre-determined long-term monitoring REA sites. Two linear 25 m transects were surveyed with a 5 m inter-transect region between the end of Transect 1 and the start of Transect 2. The LPI diver determines the benthic composition at 20 cm intervals for a total of 125 data points per transect. All living benthic elements (e.g., coral, algae, and other invertebrates) were identified to the lowest taxonomic level possible, often substituting functional group categories for turf algae and crustose coralline algae when identification in the field was extremely difficult. In cases where the substrate is bare or covered with turf algae, the substrate composition is also noted as either sand, rock, rubble, carbonate pavement, or dead coral. The data allows for the assessment and monitoring of species composition and abundance and provide the basis for computing quantitative estimates of percent cover at higher taxonomic levels like functional group (live coral, macroalgae, turf algae) or on a finer taxonomic resolution such as genus level.
