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: Current, physical profile, and meteorological data collected as part of the Exploratory Study of Deepwater Currents in the Gulf of Mexico by Science Applications International Corporation (SAIC), 2003-02-28 to 2004-04-11 (NCEI Accession 0031345)
Abstract: This dataset includes measurements of the following parameters: Profile Currents, currents, Temperature (water), salinity, pressure, profile CTD, PALFOS profile CTD and currents, PIES (estimates of vertical profiles of temperature, salinity, density and referenced geostrophic velocities), remote sensing (SST, SSH). The data were collected on the following cruises: LH845-03, LH846-03, LH847-03, PE04-10, PE04-12, PE04-17, TM080-04, PE04-34, PE04-35, TM084-04.

During this study fixed position moorings supporting acoustic doppler current profilers (ADCPs), fixed level current meters, and a variety of sensors to measure conductivity, temperature and pressure. Additionally, inverted echo sounders with pressure (PIES) were placed on the bottom at specific locations over the study area. This placement was coordinated with both current measurements and the coordinated remote sensing component of this study - in particular sea surface height. The final observations were provided by both profiling (PALFOS) and fixed level (RAFOS) drifters placed in the study area but allowed to drift and provide lagrangian information as well as C/T profiles where PALFOS floats rose to the surface every ten days. The primary objectives of the study were to develop an improved understanding of the conditions and processes that resulted in the documented circulation patterns in the study area and how these related to forcing mechanisms important to the overall upper and lower-layer Gulf circulation and transport. Results showed that in the relatively anomalous study interval, upper layer circulation patterns dominated Loop Current related eddies (cyclonic and anticyclonic). Relatively weak correlation could be defined between upper and lower layer circulation patterns. Lower-layer currents were apparently strongly affected by the presence of the Sigsbee Escarpment. Many measured current patterns could be related to topographic Rossby waves of various periods that varied with position relative to the Loop Current and bottom topography.

The Minerals Management Service (MMS) awarded a contract to Science Applications International Corporation (SAIC) to conduct a four-year study titled: Exploratory Study of Deepwater Currents in the Gulf of Mexico (often referred to as simply the Exploratory Study).
