ACM12 (Deep Basin Southwestern Boundary - German component)

This component of the Deep Basin experiment produced 30 current meter records from 6 moorings. From here you can

• View metadata and/or download current meter 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.
• Read a brief description of the experiment.
• View a map of the array.
• View a vertical section that shows array details.
• Move up one level to the list of WOCE experiments.

If you download any of the records you should read the note on file format.

The joint array extended in a line running from the edge of the continental shelf, southeastward across the Santos Plateau and the Vema Channel, to the Rio Grande Rise (see map). The goal was to measure inflow and outflow along the southern boundary of the Brazil Basin. For a detailed description of the purpose and rationale of this segment of the Deep Basin experiment, as well as data plots and statistics, see the joint technical report WHOI-94-07, IFM-Kiel 243. In addition, there is a relevant note in WOCE Newsletter #17, dated November 1994. See also

netCDF is a self-documenting format that can be accessed by a variety of software tools. We have included here a Matlab script that can be used to read netCDF current records in an environment that contains the Matlab/netCDF interface created by CSIRO. You can Click here to learn more about netCDF.

We are aware that users who are unfamiliar with netCDF or who lack software to deal with it, may find the netCDF format more a deterrent than an aid to effective use of the data. We have included in this CDROM set a second disk that is identical to this one, except that the current meter records have OSU's "Stranger" format. The Stranger format, like netCDF, is self-documenting but utilizes the ASCII code. It is easily readable by both humans and computers; you may find it preferable to netCDF.
