Temperature, Salinity, and Velocity observations from a deep mooring in Sermilik Fjord from August 2015 to July 2017

Moored time series of temperature, salinity, and velocity from a deep mooring deployed in Sermilik Fjord, East Greenland, from August 2015 to July 2017. The mooring was deployed mid-fjord, at 65.8709 degrees North (N), 37.9036 degrees West (W) (water depth of 860 meters (m)). Temperature and salinity were observed at five depths by Seabird Microcats. The velocity was observed by an RDI Long Ranger 75 kilohertz (kHz) Acoutstic Doppler Current Profiler (ADCP), providing a velocity profile over the upper 400 m of the water column. These data were collected as part of a long-term project to monitor Sermilik Fjord to determine what water masses flow into the fjord; in particular, if warm, Atlantic water from the Irminger Sea is able to penetrate into the fjord. Observations have been collected in the fjord since 2008.
