OMG Narwhals Shipboard Conductivity, Temperature, and Depth (CTD) profiles, 2018-2020

This OMG Narwhals dataset contains measurements from the ship based full water column CTD profiles that were obtained during summer mooring deployment/recovery cruises. <br><br>NASA’s Oceans Melting Greenland (OMG) campaign obtained oceanographic observations around Greenland at an unprecedented spatial scale and confirmed that the ocean plays a key role in Greenland glacier acceleration and retreat. Yet, ocean observations along Greenland’s margins are biased toward summer months with relatively few year-round measurements. OMG Narwhals, a project coupled with NASA’s OMG mission, seeks to understand the ecological importance of glacial habitats to narwhals. Narwhals return to glacial outlets and fjords each summer with high site fidelity but what attracts them to specific glacier fronts remains unclear. Seafloor-mounted ocean moorings with marine mammal acoustic recorders and oceanographic instruments were deployed near three glacier fronts with known narwhal presence in Melville Bay, northwest Greenland.
