Water physics and chemistry data were collected using moored current meter and bottle casts in the Coastal Waters of New Jersey from March 8, 1974 to May 13, 1974. Data were submitted by Atlantic Oceanographic Meterological Laboratory as part of the Mesa New York Bight (MESA - NYB) project. Data were processed by NODC to the NODC standard Water Physics and Chemistry Data (F004) format. Full water physics and chemistry descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/f004.html. The F004 format is used for data from measurements and analyses of physical and chemical characteristics of the water column. Among chemical parameters that may be recorded are salinity, PH, and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll, and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity, and current velocity (east-west and north-south components). Cruise and station information, including environmental conditions of the study site at the time of observations, is also included.

XBT data were collected from the BARTLETT in support of the Integrated Global Ocean Services System (IGOSS). Data were collected by the US Navy; Naval Oceanographic Office (NAVOCEANO) from 12 January 1974 to 07 March 1974. 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.

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.

The project area is composed of 16 counties in the State of South Carolina - Cherokee, Union, Laurens, Greenwood, Newberry, Chester, Fairfield, Lancaster, Chesterfield, Marlboro, Darlington, Dillon, Marion, Williamsburg, Clarendon, and Orangeburg. The project area consists of approximately 10,194 square miles including a buffer of 50 feet along the edges of the project area and an additional buffer in some areas. The project design of the lidar data acquisition was developed to support a nominal post spacing of 1.4 meters. The Fugro EarthData, Inc. acquisition team of Fugro Horizons, Inc. and North West Group acquired 721 flight lines in 44 lifts from January 15, 2008 through February 10, 2008. The data was divided into 5000' by 5000' foot cells that serve as the tiling scheme. Lidar data collection was performed with a Cessna 310 aircraft, utilizing a Leica ALS50-II MPiA sensor, collecting multiple return x, y, and z data as well as intensity data. Lidar data was processed to achieve a bare ground surface (Classes 2 and 8). Lidar data is remotely sensed high-resolution elevation data collected by an airborne collection platform. Using a combination of laser range finding, GPS positioning and inertial measurement technologies, lidar instruments are able to make highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures, and vegetation.

The following is the text of the abstract provided by BCO-DMO: GLOBEC 2000: Factors Affecting the Distribution of Juvenile Salmon in the Gulf of Alaska J. Helle (NMFS/AFSC, Auke Bay Laboratory) E. D. Cokelet (Pacific Marine Environmentla Laboratory), E. V. Farley, Jr. (NMFS/AFSC, Auke Bay Laboratory), A. B. Hollowed (NMFS/AFSC), P. J. Stabeno (Pacific Marine Environmental Laboratory) "Remarkable changes in atmospheric, oceanic and biological conditions have occurred in recent decades in the North Pacific Ocean including declines in the marine survival of some salmon stocks. Fishery scientists generally agree that in the first few months after leaving freshwater, salmon survival and growth are linked to oceanic variability. The purpose of this research is to focus National Marine Fisheries Service studies on the GLOBEC region, augment oceanographic measurements and determine what biological and physical factors influence the distribution of juvenile salmon. Three general hypotheses are explored in this proposal: (1) juvenile salmon prefer the buoyancy-driven Alaska Coastal Current (ACC) at the head of the Gulf of Alaska, (2) they associate with oceanic temperature, salinity, current and prey fields, and (3) they migrate landward of Kodiak Island in the ACC rather than seaward in the Alaskan Stream. Annual, summer cruises aboard a chartered fishing vessel will catch juvenile salmon on 10 transects between Yakutat Bay and Kodiak Island. The vessel will be outfitted with a thermosalinograph to measure sea-surface temperature and salinity, and with an Acoustic Doppler Current Profiler (ADCP) - each operating continuously for fine-scale resolution. Modeled tidal currents will be removed from ADCP measurements to reveal the mean flow fields. At each trawl site, temperature and salinity profiles will provide water-column properties, and bongo-net hauls will give zooplankton distributions. Stomach samples from juvenile salmonids will be analyzed in the laboratory for diet composition and compared with zooplankton distributions. Analysis of salmon otoliths for hatchery thermal marks and Genetic Stock Identification techniques will be used to determine the home stream of hatchery and wild stocks in the Gulf of Alaska and their distribution with respect to oceanographic regimes. Retrospective analysis of catch per unit effort versus oceanographic and prey factors will reveal what affects the distribution of pink, chum, coho and sockeye salmon in the study region. Proxies for bio-physical factors will be developed and compared with salmon-run size."(project proposal) Data Collection Details Types: CTD profiles, ADCP profiles of ocean current, juvenile salmonid catch statistics from trawls, salmonid stomach samples analyzed for diet composition, salmonid otolith analyses, Genetic Stock Identification, zooplankton distributions from bongo-net hauls. Platform: Chartered fishing vessel Spatial extent: 10 transects perpendicular to the coast between Yakutat Bay and Kodiak Island Temporal extent: ~2 weeks each July-August of 2001-2004.

Summary

Description

Physical, meteorological, and other data were collected from surface sensors, bottle casts, and CTD casts from the DISCOVERER. Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) as part of Outer Continental Shelf Environmental Assessment Program (OCSEAP) from 09 November 1977 to 16 November 1977. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output Format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f022.html. An analog file for this accession is available from NODC user services. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
