The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Cloud amount/frequency, NITRATE and other data from AIRCRAFT, USS DE STEIGUER (AGOR 12) and other platforms in the North Pacific Ocean from 1985-10-31 to 1986-08-05 (NCEI Accession 8700017) |
| Abstract: | Data has been processed by NODC to the NODC standard Bathythermograph (XBT Aircraft) (C118), 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 C116/C118 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments.

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. |

| Supplementary information: | Note: Metadata for this accession were extracted from a legacy database maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description. To develop more accurate metadata, NCEI reviews metadata for all accessions on an ongoing basis. Points of contact for this data set include: Contact info: Agency: US NAVY; NAVAL POSTGRADUATE SCHOOL PI: N/A Address: address: 833 DYER ROAD city: MONTEREY state: CA postal: 93943 country: UNITED STATES In this accession, NCEI has archived multiple versions of these data. The latest (and best) version of these data has the largest version number. |
