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, or view a vertical section that shows instrumentation. 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.

Description of ACCP-3

Five moorings containing current meters, CTDs, and temperature recorders were deployed east of Abaco Island in October 1995 (see map). All moorings were recovered approximately 20 months later (though the upper 1000 m of one mooring was lost). 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-1, 2, and 3 moored arrays have been designated as the US WOCE western boundary current arrays for the subtropical Atlantic.

Format of the current records

These files have been compressed with the ZIP compression utility. After downloading them, you will need to expand them. On a PC, WinZip or Pkunzip will do the job. Other utilities are available for the Unix and Macintosh environments. After expansion, you will have ascii files in OSU's stranger format.

The stranger format begins with several lines of header information that are meant to be machine-readable. They contain a Fortran format specification that will be useful in reading the file, a pointer to the first line of data, and a description of the data. Each line of the current record itself contains the time of the sample, the values recorded, and a line count.

Please be aware that end-of-line in these files is a carriage-return plus line-feed (the PC convention). This means that in a Unix environment (where a single line-feed serves as end-of-line) you may want to remove the carriage-returns.
