Moored Current Measurements in Orphan Basin

Moored current measurements were made at 8 sites in Orphan Basin, during the period from June 2004 to May 2010. Seven of the sites have been on a line across the basin, and the 8th site was chosen to examine variability in the along-slope direction. Moorings with current meters distributed over the water column have been deployed at 4 of the sites. Moorings with only near-bottom, or near-bottom and mid-depth, instruments have been deployed at the other 4 sites.
The project has been funded by the Program on Energy Research and Development (PERD), with additional support provided by Exxon Mobil and partners for the 2005-07 moorings.
