Temperature, salinity, dissolved oxygen, turbidity, and fluorescence profiles from Sermilik Fjord and the Southeast Greenland shelf, collected in August 2023

Eighty-one temperature, salinity, dissolved oxygen, turbidity, and fluorescence profiles from Sermilik Fjord and the Southeast Greenland shelf. The temperature, salinity, and dissolved oxygen profiles were collected with a Seabird 25plus conductivity-temperature-depth (CTD) (serial #0251108); the turbidity and fluorescence profiles were collected with a Seabird ECO FLNTU (serial #7748). The profiles were collected during August 2023 from research vessel Tarajoq. The profiles were manually examined and are provided as 1-meter (m) bin averages. The fjord survey was comprised of an along-fjord section and a section spanning the mouth of the fjord. The shelf survey traces the trough that feeds Sermilik. These data were collected as part of a project examining the physical, biogeochemical, and ecological systems of the fjord. The also contributed to 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.
