ACM29 (Labrador Sea)

This experiment produced 25 current meter records from 9 moorings. You can view metadata and download the current records by clicking on links in the table below. Each current meter record is identified in the table by its depth. A brief description of the experiment also is available. You may want to look at a map first to see where the mooring was. 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.

Description of WOCE component ACM29

ACM29 was a multi-year mooring near the former location of Ocean Weather Station Bravo, in the Labrador Sea. The goal of ACM29 was to obtain current and physical property data to aid in understanding Labrador Sea Water formation and the variability in its properties induced by interannual variations in the heat and salt fluxes.

Time series of current speed, current direction, water temperature and in some cases pressure were obtained with Aanderaa RCM8 current meters. Moorings were placed at three locations: in the center of the Labrador Sea, where the water depth is about 3400 m; near the 3000 m contour at the base of the continental slope; and near the 1000 m contour on the slope (see map).

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.
