Popis

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.

Popis

Benthic grab samples were collected using a Shipek grab at pre-determined locations in the harbor. Taxonomic enumerations and biological community parameters were estimated from grab samples and used to assess habitat conditions in conjunction with sediment profile images taken at the same stations. All data were entered into a database, and habitat classes were defined for each station. The database was then used in a Geographic Information System (GIS) to characterize benthic habitat types for New York/New Jersey Harbor.

Popis

Habitat maps of the main Hawaiian Islands were created by visual interpretation of aerial photos and hyperspectral imagery using the Habitat Digitizer extension. Aerial photographs are valuable tools for natural resource managers and researchers since they provide an excellent record of the location and extent of habitats. However, spatial distortions in aerial photographs due to such factors as camera angle, lens characteristics, and relief displacement must be accounted for during analysis to prevent incorrect measurements of area, distance, and other spatial parameters. These distortions of scale within an image can be removed through orthorectification. During orthorectification, digital scans of aerial photos are subjected to algorithms that eliminate each source of spatial distortion. The result is a georeferenced digital mosaic of several photographs with uniform scale throughout the mosaic. Features near land are generally georeferenced with greater accuracy while the accuracy of features away from land is generally not as good. Where no land is in the original photographic frame only kinematic GPS locations and image tie points were used to georeference the images. After an orthorectified mosaic is created, photointerpreters can accurately and reliably delineate boundaries of features in the imagery as they appear on the computer monitor using a software interface such as the Habitat Digitizer.

A Phantom DH2+2 remotely operated vehicle (ROV) outfitted with video equipment (and other devices) was deployed fromthe NOAA Ship McAurthurII (AR04-04) in an attempt to document the presence of critical hard bottom benthic habitats believedto exist in the waters of the Olympic Coast national marine sanctuary (OCNMS). Video data from specific dives falling withinthe bounds of the HMPR-113-2004-01d survey area were reviewed to examine the benthic characteristics as a tool for validatingsonar imagery.

Popis

File 100-022b is a 60-m ASCII grid of depth data collected near 1955 Eruption Site & Seamount in the Northwestern Hawaiian Islands as of May 2003. This grid has been produced as part of the "Bathymetric Atlas of the Northwestern Hawaiian Islands -- A Planning Document for Benthic Habitat Mapping -- Draft -- May 2003. Data sources for the downloadable grids include: multibeam bathymetry from Simrad EM1002 and EM120 sonars aboard the R/V Kilo Moana collected in October/November 2003; multibeam bathymetry data from a SeaBeam 210 sonar aboard the R/V Kai'imikai-O-Kanaloa collected in 2000-2002; LIDAR data obtained using the LADS MK II lidar system; and depth data derived from IKONOS satellite imagery. No tidal corrections have been applied to the data. The data source location for each type of data is indicated in the "dot plot" browse objects. Additional single-beam bathymetric data are available in this area and are indicated on the 100-022b Plot C browse object, but these less accurate depths are not included in the downloadable grid. Multibeam data were processed using SABER editing software and MBSystem and multibeam, LIDAR and IKONOS data were integrated using MBSystem, and GMT. Grid spacing is 60-m, horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation.

Popis

The NEFSC bottom trawl survey is a fisheries independent, multi-species survey that provides the primary scientific data for fisheries assessments in the U.S. mid-Atlantic and New England regions. Two bottom trawl surveys are conducted each year, one in the spring and one in the autumn. The survey is a standardized, stratified random design, with stratification based on bathymetry and multiple trawl sites within each stratum. Trawl sites are selected randomly, but the overall ship path is south to north. The survey covers the continental shelf and U.S. exclusive economic zone (EEZ) from Cape Hatteras, North Carolina into the Canadian EEZ. The primary gear is a bottom trawl, with CTD, multifrequency echosounder, and a host of other scientific sensor data collected ancillary to the bottom trawl catches.

In October 2012, WSI (Watershed Sciences, Inc.) was contracted by the Puget Sound LiDARConsortium (PSLC) to collect Light Detection and Ranging (LiDAR) data for the EntiatRiver site in central Washington. The area is adjacent to several other LiDAR projectscollected in the greater Wenatchee area since 2008. Data were collected to aid inassessing the topographic and geophysical properties of the study area to supportfault line and geologic instability within the area. The Entiat site covers 67,067 acres,collected June 23, 26, 28, 29 and 30, 2013.
