ICM3 (Indian Ocean at 20 deg South)

This experiment produced 56 current meter records from 19 moorings. 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.

Brief description of the Experiment

The ICM3 array was designed to aid the development of a description of the water characteristics, velocity structure and transport of the three systems of deep western boundary currents in the Indian Ocean. The boundary currents carry water of Antarctic origin northward into the three major basins of the Indian Ocean. Knowledge of their transports will provide direct information about the overturning rate of the Indian Ocean.

The three components of ICM3 span the western portions of the Mascarene Basin (West Array), the Central Indian Basin (Central Array) and the West Australian Basin (East Array) from a nominal depth of about 2500 m to 100 m off the bottom (see map). The moorings were deployed between 5 May and 1 June, 1995 on the WOCE Hydrographic Programme line I3 conducted by R/V Knorr. They were recovered between 16 January and 6 February by the R/V Melville. Each array instruments a zonal section at 20 degrees South. A diagram that shows details of the three arrays is available.

Some results are discussed in

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.
