SAA Abbrevation for Satellite Active Archive, a digital library of real-time and historical satellite data from NOAA’s POES. SAA allows users to search inventories of satellite data, preview representative Earth images of that data, and to download the data for further processing and analysis.

SAARI Acronym for the South Atlantic Accelerated Research Initiative, an ONR research program primarily directed toward improvement of the description of the subtropical South Atlantic. It focused on the poleward corners of the subtropical gyre, i.e. the separation of the Brazil Current and its confluence with the Malvinas or Falkland Current in the southwest, and the Agulhas Retroflection and Benguela Current in the southeast. See Gordon [1988].


SABRE Acronym for South Atlantic Bight Recruitment Experiment, a NOAA program to stud the birth-date history of survivors (larvae, late larvae, and juveniles) to determine which life history phase or passage (spawning, transport across the shelf, inlet ingress, estuarine development, inlet egress) regulates recruitment variability in annual cohorts of transgressive species like Atlantic menhaden.

SABSOON Acronym for South Atlantic Bight Synoptic Offshore Observational Network, a NOPP funded program to develop a real–time observational network on the continental shelf offshore of South Carolina and Georgia. The network consists of eight large offshore platforms – currently operated by the U.S. Navy for flight training – being instrumented to provide a range of oceanographic and meteorological observations on a continuous, real–time basis. The grid covers an area of 155 km by 50 km and a depth range from 25 to 45 m, with an existing communcations system allowing high bandwidth, real–time data transmission to shore.

SAC Acronym for Shipboard ADCP Center, now renamed to JASADCP.


SACCF Abbreviation for the Southern ACC Front.


SADCO Acronym for the South African Data Centre for Oceanography, a center that stores, retrieves and manipulates multi-disciplinary marine information from the areas around Southern Africa.

S-ADCP Abbreviation for Salinity–ADCP.

saddle The official IHO definition for this undersea feature name is “a broad pass or col, resembling in shape a riding saddle, in a ridge or between contiguous elevations.”


SAF Abbreviation for Subantarctic Front.


SAFDE Acronym for the Sub–Antarctic Flux and Dynamics Experiment, a program designed to collect observations of the ACC south of Tasmania that would permit direct evaluation of the momentum, energy and vorticity budgets. The experiment lasted two years - from April 1995 to March 1997 - and collected multi–year observations of currents and temperatures in both a small current meter mooring array with a diameter of about 70 km, and along a SSW–NNE section perpendicular to the expected mean axis of the ACC at the Subantarctic Front. The measured variables were found to be coherent horizontally and vertically in broad, sub–inertial frequency bands, a rarity with such oceanic measurements.

The center of the SAFDE array consisted of nine subsurface, nearly full depth moorings deployed as a local dynamics array (LDA), of which four were fully and three partially recovered. The array also included a suite of 17 (15 recovered) horizontal electrometers (HEM) and 18 (all recovered) inverted echo sounders (IES) to obtain time series of the vertically averaged horizontal water velocity, the temperature structure, and the dynamic height structure. The HEMs measure the horizontal electic fields which are theoretically related to the conductivity–weighted, vertically–averaged horizontal water velocity Chave and Luther [1990].
