This experiment produced

• 31 current meter records (Aanderaa and VACM)
• 4 records from Seacat CTDs
• 4 records from Benthos temperature recorders

You can view metadata and/or download the records by clicking on links in the table below. A brief description of the experiment also is available. Each record is identified in the table by its depth and the name of the mooring. You may want to look at a map of the array to see where the moorings were. If you download any of the files you should review the note on file format. From here you can also move up one level to the list of WOCE experiments.

All of the time series in this archive are filtered and have a time increment of 12 hours. The diurnal tides and all higher frequencies have been removed. The original unfiltered files may be available from the PI's.

Five moorings containing current meters, CTDs, and temperature recorders were deployed east of Abaco Island in February 1992 and were recovered approximately 20 months later (see map). The principal goal of the experiment was to measure the volume and heat transports of the thermohaline circulation in the western subtropical Atlantic. The project was initiated with joint support from the NOAA Atlantic Climate Change Program (ACCP) and the World Ocean Circulation Experiment (WOCE). It addressed the central issue of Element III of ACCP (observing and monitoring the thermohaline circulation) and of the WOCE Moored Velocity Measurement Program (direct flux sections).

This experiment also had the objective of preserving the continuity of the western boundary current transport time series begun by the STACS Program (Subtropical Atlantic Climate Studies) in 1986. The goal of STACS was to obtain multi-year records for the investigation of interannual variability of climate-relevant flow transients. The ACCP moored array has been designated as the US WOCE western boundary current array for the subtropical Atlantic.
