SCM6 (ADOX)

This experiment produced 29 current meter records from 9 moorings. You can view metadata and download current records by clicking on links in the table below. Each current meter record is identified in the table by its depth and the name of the mooring. You can click here to see a map that shows where the moorings were. A brief description of the experiment also is available. If you download any of the current meter records you should review the note on file format. From here you can also move up one level to the list of WOCE experiments.

CMDAC has been fortunate to obtain detailed critiques of data quality from CEFAS, and we have included many of them here. We want to emphasize that in spite of these warnings of possible and actual instrument and tape problems, this is a high-quality dataset - one of the best we have received. Most of the WOCE current meter data that we have obtained has come without such cautions, even when it is obvious that some of the records are of poor quality.

Description of ADOX

The major portion of this dataset consists of current records from a linear array of 8 moorings extending across the deep passage between the Crozet Islands and the Kerguelen Plateau. There is an additional current meter record from a single mooring northwest of the Crozet Islands. In all, 29 good records were obtained. Aanderaa current meters with a sampling interval of one hour were employed thoughout. All of the instruments recorded speed, direction, and temperature. One instrument recorded pressure (in addition) and another recorded conductivity.

A goal of the experiment was to measure the flow of deep and bottom waters passing eastward from the Enderby Abyssal Plain to the southern Indian Ocean via deep topographic gaps to the northwest and southwest of the Kerguelen Plateau. To this end current meters were placed in the main gap between Crozet and Kerguelen, and supplemented with a mooring in the deep cleft immediately to the northwest of Crozet island.

In addition, two of the moorings in the main Crozet-Kerguelen array were extended upward into the near-surface layers to aid the subsequent SWINDEX investigations into the interactions of the Agulhas and Antarctic Circumpolar Currents.

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.
