Video of the Week: Study Examines Melting of Greenland

A team of scientists on board a former Danish fisheries research ship and icebreaker is working to measure changes to Helheim glacier and the fjords around it. Helheim, named for the world of the dead in Norse mythology, is one of Greenland’s largest outlet glaciers. This means that it is one of the primary locations for meltwater leaving the Greenland ice sheet. It is responsible for 4% of Greenland’s annual mass loss. 

Understanding the melting at Helheim is crucial because Greenland has the potential to contribute 27cm of sea level rise within the lifetimes of today’s children. 

The project studies Helheim using several technologies in pursuit of the team’s goal to create complex models of glacial fracturing. Some of the methods being used to collect data include drilling into the glacier to determine how much snow is deposited on the glacier during storms, using seismometers to detect the spread of concealed fractures, and checking the status of the glacier’s terminus four times daily with an automatic laser system to monitor calving, among other sources of information.
