The water depth and temperature data was collected as part of Equatorial Pacific Ocean Climate Studies from NOAA Ship Discoverer and NOAA Ship Oceanographer. The data was collected from the TOGA (Tropical Ocean Global Atmosphere) Area in the Pacific (30 N to 30 S) from April 23, 1979 to May 21, 1982. The originator's bathythermograph (XBT) data was submitted in a tape by Margie McCarty of Pacific Marine Environmental Laboratory, Seattle, WA. The data has been converted and is now available on line in C116 file format of NODC.

Biological data from the Deep Ocean Mining Environmental Study (DOMES) was submitted by R.J. Ozretich from the University of Washington. The data were collected in the North Pacific ocean on three cruises of the OCEANOGRAPHER from April 26, 1978 to March 22, 1979. The cruises can be identified by the following reference numbers: RP01OC78 - L01008; RP13OC78 - L01009; and RP09OC79 - L01010. The parameters reported are temperature, salinity, oxygen, apparent oxygen utilization (AOU), nutrients (PH, Si, NO3, NO2, NH4), ATP, chlorophyll and phaeopigment concentrations. Original DOMES hydro data submitted on tape has been converted into the current NODC data storage format.

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.

This dataset contains XBT temperature profiles that have been edited to exclude erroneous data. Depths are from the fall rate equation of Hanawa et al. (1995, Deep-Sea Research I 42:1423-1451). Data are in CSV format.
