Moored Current Measurements on the Scotian Rise

Moorings with near-bottom current meters were deployed at two sites over the Scotian Rise, from October 2004 to October 2008. Support was provided by the Program on Energy Research and Development (PERD) and the the National Oceanographic Centre (NOC) of the United Kingdom (UK). The PERD moorings complemented moorings deployed by NOC as part of the UK Rapid Climate Change (RAPID) Climate Change program, on a cross-slope line to the east of the AZMP Halifax line.

Since 2008, moored measurements have made at six sites on the Halifax Line of AZMP and the Extended Halifax Line of AZOMP, in collaboration with NOC and RAPID. This project is planned to continue until at least 2013.

The approximate water depths and positions, and the BIO Consecutive Numbers (for cross-referencing the datafiles in the ODI database) for the moorings, are given in the following table.
