WOCE Component ACM6

This experiment produced 42 current meter records from 8 moorings. You can view metadata and download the 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. If you download any of the records you should review the note on file format. A brief description of the experiment also is available. You may want to look at a map of the array to see where the moorings were. From here you can also move up one level to the list of WOCE experiments.

Description of WOCE component ACM6

ACM6 was a Boundary Current Array. The principal goal of ACM6 was to measure the volume transport and heat flux of the North Atlantic Current, which is the western boundary current of the North Atlantic subtropical gyre. These were the first long-term moored measurements of this important part of the global ocean circulation.

Measurements were made with Aanderaa RCM5 and RCM8 current meters. The moorings formed a linear array extending from the Grand Banks of Newfoundland (see map) southeastward into deep water. Depending on the depth of the water, instruments were placed at design depths of 400m, 800m, 1500m, 2500m, 3500m, 4000m, and 100m above the bottom. In most cases the shallowest two instruments measured speed, direction, temperature, pressure and conductivity. Deeper instruments measured speed, direction, temperature, and in some cases pressure. The records that CMDAC has acquired contain salinity rather than conductivity.

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.
