Long-term observations on the Bering Sea shelf: ADCP data from mooring site 2

Biophysical measurements have been made at mooring Site 2 (56.88N, 164.03W) almost continuously since 1995, providing the longest near continuous time-series of biophysical variables on the Bering Sea shelf. A series of moorings have also been deployed at Site 4 (57.85N, 168.87W) since 1995, providing almost six years of more sporadic data. In addition, another series of moorings have been deployed at Site 5 (59.90N, 171.70W) from 2004 to present. Added to the biophysical data collected by the moorings, water property measurements have been made at locations around the moorings and along the 70-m transect since 1995. Such long-term observations provide critical data that allow characterizations of interannual variability, quantification of regime shifts and climate change. This project partially funds continued measurements at Site 2 with water samples and plankton samples around the mooring site and along the monitoring line.
