ACM24 (FSU component of Deep Basin)

This component of the Deep Basin experiment produced 26 current meter records from 8 moorings. From here you can

Current meter arrays were deployed in the interior of the basin and across passages that connect the Brazil Basin to neighboring regions. Each array was in the water for approximately two years. We are concerned here with a line of 10 moorings that was placed in the center of the basin, with a roughly east-west alignment (see map), by Florida State University. Eight of the moorings were recovered.

The ACM24 array was designed with two primary goals:

• To observe and quantify the deep circulation, including the deep boundary currents, within the Brazil Basin.
• To observe and quantify spatial and temporal changes of the Brazil Current and its recirculation on scales of up to one year.

All but one of the moorings contained a Russian Potok II current meter at a depth of 900m, and modified Geodyne 101s at 1800m, 2800m, and 100m above the bottom. The remaining mooring contained two Geodynes, one placed 120m above the bottom and the other 7m above the bottom.
