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
