Data was collected from R/V COLUMBUS ISELIN in South Atlantic Ocean and North American Coast line-South during the Amazon Shelf Sediment Study (AMASSEDS) between May 23, 1990 to June 13, 1990. The data parameters were: pressure, temperature, salinity, oxygen, fluorescence and sediment concentration. A Neil Brown Instrument Systems Model MKIII CTD was used as the primary profiling instrument. A Sea Tech 5 cm path length Transmissometer and a Sea Tech Fluorometer were mounted near the CTD fish. On some stations the Fluoro- meter was replaced with an optical backscatter sensor to observe suspended sediment concentrations above the light transmissometer limit of 0.5 gm/l. Data was submitted in two diskettes by Dr. Richard Limeburner of Woods Hole Oceanographic Institution, Woods Hole, MA. Data has been processed and is currently available in F022-CTD-Hi-Resolution file format of NODC.

The Conductivity, Temperature and Depth (CTD) data were collected as part of Amazon Shelf Sediment Study (AMASSEDS) project. Data was collected from NW Atlantic (limit-40 W) using ship COLUMBUS ISELIN. The data was collected over a 10 day period between August 4 to August 13, 1989. Data was submitted on a floppy disk containing 86 CTD files by Dr. Richard Limeburner, Woods Hole Oceanographic Institution (WHOI), Woods Hole, MA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.

The data in this accession was collected as part of Joint Global Ocean Flux Study/ North Atlantic Bloom Survey (JGOFS/NABS) using Ships ENDEAVOR and ATLANTIS II. JGOFS North Atlantic Bloom Experiment Data; CTD Data plus Beam Attenuation and Fluorescence Data were collected by Scripps Institution of Oceanography and Moss Landing Marine Laboratory between April 20, 1989 and July 6, 1989. The originators data has been processed and is available in F022-CTD-Hi-Res file format of NODC.

Physical and meteorological data were collected using sediment sampler and other instruments from COLUMBUS ISELIN in the North Atlantic Ocean. Data were collected from 28 October 1975 to 05 November 1975 by Virginia Institute of Marine Science in Gloucester Point with support from the Outer Continental Shelf - Mid Atlantic (OCS-Mid Atlantic) project. Data has been processed by NODC to the NODC standard Bacteriology (F009) format. The F009 format is designed to support bacteriological studies of the water column and ocean bottom. Information on environmental conditions, physical measurements of the water and sediment, and density of heterotrophic, hydrocarbonoclastic, and halophilic bacteria are presented. The format contains five data record types, each 80 characters in length, sorted by station ad sequence numbers. The first nine columns for all records are to be used for file name (columns 1-3) and file identifier (columns 4-9). The file identifier, to be assigned by the originator, is a unique originator id for each data submission. After submission, the NODC reassigns to this field a unique NODC identifier for internal use.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) and High-Resolution CTD/STD (F022) formats. The C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points ("inflection points") required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB. 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.

The data presented in this submission was for the Delaware Sea Grant project R/HCE-37 titled "Fingerprinting the sources or organic matter using fluorescence spectroscopy: a feasibility study in the Broadkill River estuary." There were three types of samples included, the first was insitu samples from the Broadkill River watershed, located in southern Delaware, USA. Samples were collected at three different times of the year to represent seasonality. The second type of sample was source samples that represented the different land uses found within the watershed. The third type was the source mix samples, which mixed the varying sources to try to mimic the natural environment. Dissolved organic carbon (DOC) concentrations were measured on each sample as well as ultra-violet/visible and fluorescence spectroscopy in the form of the specific ultra-violet absorbance at the wavelength 254 nm (SUVA254) and excitation-emission matrices (EEMs).

The Conductivity, Temperature and Depth (CTD) and other data were collected as part of Office of Naval Research (ONR). CTD Data was collected from NW Atlantic (limit-40 W). Replacement data is provided for data collected using Ship CONRAD between May and June 1988. New data was collected using ship COLUMBUS ISELIN over a period spanning from November 22, 1990 to December 1, 1990. Data was submitted by Dr. Eli Katz, Lamont-Doherty Earth Observatory, Palisades, NY. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.
