This digital elevation model (DEM) is a part of a series of DEMs produced for the National Oceanic and Atmospheric Administration Office for Coastal Management's Sea Level Rise and Coastal Flooding Impacts Viewer. The DEMs created for this project were developed using the NOAA National Weather Service's Weather Forecast Office (WFO) boundaries. Because the WFO boundaries can cover large areas, the WFO DEM was divided into smaller DEMs to ensure more manageable file sizes. The Los Angeles/Oxnard (CA) WFO DEM was split into two smaller DEMs. They are divided along county lines and are: 1. Los Angeles/Oxnard (CA) WFO - Los Angeles and Ventura Counties 2. Los Angeles/Oxnard (CA) WFO - Santa Barbara and San Luis Obispo Counties This metadata record describes the DEM for Los Angeles/Oxnard (CA) WFO - Santa Barbara and San Luis Obispo Counties. The DEM includes the best available lidar data known to exist at the time of DEM creation for the coastal areas of Santa Barbara and San Luis Obispo counties, that met project specifications. The DEM is derived from LiDAR data collected for the California Coastal Conservancy between 2009 and 2011. Hydrographic breaklines used in the creation of the DEM were obtained from the California Coastal Conservancy. The DEMs are hydro flattened such that water elevations are less than or equal to 0 meters. The DEM is referenced vertically to the North American Vertical Datum of 1988 (NAVD88) with vertical units of meters and horizontally to the North American Datum of 1983 (NAD83). The resolution of the DEM is approximately 5 meters.

The three files contain trace metal data from North, Central and South Atlantic observed in bottom sediment samples along the East Coast Continental Slope and Rise region. Samples were collected from a large number of surveys from May 1983 to July 1986. These data were collected by National Marine Fisheries Service, Woods Hole for the US East Coast Continental Rise/Slope region. The documentation includes the field variables (including region, box core number, location, and type of metal recorded) and a listing of cruises.

This project is a cooperative effort among the National Ocean Service, National Centers for Coastal Ocean Science, Center for Coastal Monitoring and Assessment; the University of Hawaii; and Analytical Laboratories of Hawaii, LLC. The goal of the work was to develop coral reef mapping methods and compare benthic habitat maps generated by photointerpreting georeferenced color aerial photography, hyperspectral and IKONOS satellite imagery. The enhanced spectral resolution of hyperspectral and control of bandwidths of multispectral data yield an advantage over color aerial photography particularly when coral health and time series analysis of coral reef community structure are of interest. Depending on the type of instrument, a spectral imaging system can be utilized to see multiple colors from ultraviolet through the far infrared range. The AURORA hyperspectral imaging system collected 72 ten nm bands in the visible and near infrared spectral range with a 3 meter pixel resolution. The data was processed to select band widths, which optimized feature detection in shallow and deep water. 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.

Bathythermograph data were collected from the CHINCOTEAGUE within a 1-mile radius of Ocean Weather Stations D (4400N 04100W) and H (3800N 07100W) and in transit. Data were collected by the United States Coast Guard from 18 June 1962 to 19 July 1962. 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.

This image represents a 0.5 meter resolution backscatter mosaic of Grammanik Bank, south of St. Thomas, US Virgin Islands.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 the US Virgin Islands from 2/1/05 to 2/12/05. Data was acquired with a pole-mounted Reson 8101 ER multibeam echosounder (240 kHz) and processed by a NOAA contractor using CARIS HIPS v5.4 software. Data has all correctors applied (attitude, sound velocity) and has been reduced to mean lower low water (MLLW) using final approved tides from NOAA COOPS. Data is in UTM zone 20 north, datum WGS84. The backscatter component of the bathymetry data were processed by the Hawaii Mapping Research Group (HMRG), University of Hawaii using the HAWAII MR1 Sidescan Sonar Software Suite. The data were corrected for angle varying gain, transmit power and pulse width. Electronic and acoustic noise, such as striping due to across track variations in amplitude and speckling due to transducer motion, were removed.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.

Wind Wave Spectra and other data were collected at the fixed platforms in the Gulf of Mexico, South Pacific Ocean, East/West Coast of US, and Great Lakes from August 1, 2000 to August 31, 2000. Data were collected using moored buoys at the fixed locations. Data were submitted and collected by the National Data Buoy Center.

Data from Coral Reef Ecosystem Division (CRED), NOAA Pacific Islands Fisheries Science Center (PIFSC) Wave and Tide Recorders (WTR) provide a time series of temperature, wave and tide data at coral reef sites. Data is typically collected for a duration of 2 years using a SBE26 or SBE26plus SEAGAUGE Wave and Tide Recorder (Sea-Bird Electronics, Inc., www.seabird.com). Sensors include: Real-time clock, thermistor, and Digiquartz temperature-compensated pressure sensor. When a WTR is recovered, a new one is typically deployed in the same place. Time series data combining multiple deployments from a given site may also be available. Please contact CRED with any questions.
