UD scientists collect data from ocean sensors underneath Petermann Glacier

In August 2015, University of Delaware oceanographer Andreas Muenchow and colleagues deployed the first UD ocean sensors underneath Petermann Glacier in North Greenland, which connects the great Greenland ice sheet directly with the ocean. Petermann Glacier is the second largest floating ice shelf in the northern hemisphere.

Located approximately 16 to 2,300 feet below the glacier, the five ocean sensors are connected to a weather station at the surface, creating the first cabled observatory on a floating, moving, and rapidly melting Greenland glacier.

The researchers recently reported in the journal Oceanography that sensor data from August 2015 to February 2016 confirms that that the floating ice shelf is strongly coupled, or tied, to the ocean below and to Nares Strait, and temperatures vary with the tides and seasons.
