PLEASE NOTE there is discrepancy between the content of actual data in this accession and the abstract information that was present in Thaila folder for this accession. Following abstract is based on the information from Thaila folder. MECCAS II (Microbial Exchanges and Coupling in Coastal Atlantic Systems) cruise data collected by the R/V Gyre at the mouth of the Chesapeake Bay. Each of four MECCAS cruise data sets is divided into 3 files: File 1 contains underway surface mapping data. 12 parameters measured included location, temperature, salinity, ammonium, nitrate, nitrite, phosphate, and silicate at +/- 0.03-0.1 uM. File 2 contains vertical profiles at stations along mapping routes; the same 12 parameters as described above were measured. File 3 contains vertical profiles at drogue stations; 96 parameters were measured. Parameters include CTD data, zooplankton data (biomass, heterotrophic and autotrophic grazing rates, and production rate estimates), bacteria data (cell count, estimated volume, nutrient assimilation, and production rate estimates), and nanoplankton data (abundance of pigmented and non-pigmented eukaryotes and estimates of bacterial removal rates). Nutrient data contained in File 3 includes dissolved free amino acids (carbon content in free glutamic acid, serine, glycine, and alanine). Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format. 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.

Zooplankton data were collected from mid-water trawls from the NE Pacific Ocean (limit-180). Data were collected from NOAA Ship GEORGE B. KELEZ from 03 May 1963 to 22 November 1963. Data are in a comma separated value (.csv) format.

Zooplankton data were collected using zooplankton net casts and other instruments in the Delaware Bay and North Atlantic Ocean from November 3, 1976 to November 18, 1977. Data were submitted by Virginia Institute of Marine Science - Gloucester Point as part of the Ocean Continental Shelf (OCS - Mid Atlantic) project. Data were processed by NODC to the NODC standard Zooplankton (F004) format. The F124 format is used for data from sampling and analysis of marine zooplankton. Information on zooplankton abundance, distribution, and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: cruise information, position, date, and time of sampling; bottom depth, sampling depths, temperature, and salinity; gear type, volume of water filtered, total dry and wet weight, and other data for total haul; and data for subsamples by species. Data on zooplankton catch by species may include subsample size, zooplankton concentration, life history code, and numbers of adults, juveniles, eggs, and larvae. Estimated density of holoplankton and meroplankton and data on ichthyoplankton may also be reported. A text record is available for comments. Note: there are two options for reporting subsample counts of individuals at different life history stages. If life history codes are used, only number of adults should be reported on that record. Additional separate records should then be used to report number of juveniles and so on. Alternatively, life history codes may not be used and number of adults, juveniles, and so entered in the proper fields of a single record.

Zooplankton and other data were collected using net casts from T-441 in the Coastal Waters of California. Data were collected from 19 April 1967 to 13 September 1967 by University of California; Institute of Marine Science.
