Currents, Ice Velocity, Temperature, and Salinity from moorings around Hanna Shoal, Chukchi Sea, 2012-2014
These data were collected as part of the physical oceanographic component of the Chukchi Sea Offshore Monitoring in Drilling Area (COMIDA) Hanna Shoal Ecosystem Study. Hanna Shoal is a topographic feature in the northeastern Chukchi Sea that is both shallow (as little as 20m deep) and biologically p...

These data were collected as part of the physical oceanographic component of the Chukchi Sea Offshore Monitoring in Drilling Area (COMIDA) Hanna Shoal Ecosystem Study. Hanna Shoal is a topographic feature in the northeastern Chukchi Sea that is both shallow (as little as 20m deep) and biologically productive. The earlier COMIDA: Chemistry and Benthos (CAB) study identified it as an area at which to focus additional ecological monitoring. To define the circulation around the Shoal, Acoustic Doppler Current Profilers (ADCPs) were deployed on six moorings on its northwest and northeast slopes on the 40, 50, and 60 m isobaths.
