Project Description:
Scientists continue to investigate the multitude of stress factors causing the steady decline of the cryosphere. Jet Propulsion Laboratory’s Ocean Melting Greenland (OMG) Campaign points to Atlantic water (AW) influencing the rate of mass ice loss of the Greenland Ice Sheet (GIS) by melting ocean terminating glaciers from underneath. The stability of cryospheric systems are of great concern in the Canadian High Arctic. Glacial mass loss is evident around the sole ice sheet, the Devon Ice Cap. It marks the eastern extent to a world thoroughfare, the Northwest Passage. Throughout the Arctic, increasing summer temperatures advance ice sheet surface melting and drainage through terminating glaciers. Canadian cryospheric researchers question why the terminating glaciers of Croker Bay, which drain into Lancaster Sound exhibit melt variations that are synchronous but do not align with any glacier velocity classification. Across Baffin Bay, baseline ice mass loss factors have been addressed at neighboring Northwest Greenland glacial fjords to assess the stability of the GIS. OMG finds that GIS glaciers have melt patterns that are influenced by Atlantic Ocean originating warmer currents. Further into the sound, Barrow Strait Realtime Observatory and offshore Baffin Bay observations demonstrate evidence of AW. Are the terminating glaciers in Croker Bay off the Devon Ice Cap influenced by AW, circulating off Baffin Bay? Bathymetric data from the Canadian Hydrographic Office will be further reviewed to identify the nature of the subsurface geometry of Croker Bay in order to aid in station and survey route planning. A permit will be secured to conduct a field study in Canadian waters from the Nunavut Research Institute for Croker Bay. In late July, the field cruise will set off at the onset of the breakup of the landfast ice within Lancaster Sound and Crocker Bay. American Graduate student, Nicole Trenholm will coordinate the research cruise in conjunction with a American recreation vessel of opportunity. The vessel will leave from Upernavik, NW Greenland, to then cross Baffin Bay before entering Lancaster Sound. The vessel is prepared for daily status reports submissions to the Canadian Coast Guard. The existence of AW will be verified en route towards the tidal glacial fjord of Croker Bay with a few seldom CTD casts as weather permits. A recently calibrated CTD will be used to conduct casts throughout the bay. The circulation of Croker Bay currents will be revealed after review of all CTD cast hydrographic profiles. Existing Canadian soundings relay key insights including the seafloor topography that may demonstrate a barrier that withholds AW from reaching the glacial terminus. Research collaboration is of great interest with Canadian cryospheric and physical oceanographic researchers: Dr. Clark Richards, Dr. Andrew Hamilton and Dr. Wesley Van Wychen. They plan on utilizing the reconnaissance hydrographic data once archived. Investigation of the subsurface forces of glacial melt may yield new insight to the Devon Ice Cap melt regime while general circulation data for Croker Bay can also be a source for Dr. Hamilton’s regional ocean circulation model. The results of this study will directly tie the unseen deep ocean melt factor to Canada’s Devon Ice Cap stability while gauging if AW at glacial fronts is a driver for chlorophyll production rates in the Arctic as a whole. NIcole Trenholm will collect, analyze and share data and study results with collaborating scientists and agencies. A publication will be generated if findings are substantial to polar science, where collaborators will be invited to review.
