Our fibre-optic experiment on Store Glacier have produced the most detailed record of temperature from the surface of the Greenland Ice Sheet to its bed, more than 1000 metres below. The result significantly improves our understanding of ice sheet thermodynamics. Compared to previous studies, which used discrete temperature sensors – often located tens or even[…]

We are happy to see our observations of deep mixed-mode crevasses at Store Glacier featured as Editors’ highlight in Eos magazine this week: Evidence of Crevasses Transporting Heat Deep into Greenland Ice

RESPONDER borehole observations at Store Glacier have identified deep mixed-mode crevasses that penetrate far deeper into the ice than model predictions. For decades, crevasse depths have been estimated by calculating opening and closure rates theoretically. These simple calculations predicted crevasses would penetrate only some tens of metres below the surface of a glacier, but the[…]

RESPONDER has produced the most detailed record of calving record from a marine-terminating glacier in Greenland. Using a terrestrial radar interferometer, our team recorded hundreds of calving events on a daily basis at Store Glacier and a total of 8,026 separate events. The icebergs that discharged from Store Glacier ranged from boulder sized (<1,000 cubic[…]

Seismology is one of the standard pieces of the glaciological toolkit. Glaciologists have long known that seismic energy – vibrations travelling through the ice – can be used for actively imaging glacier structure, or for listening out for the natural rumblings as a glacier scrapes across its bed and water drains through networks of channels.[…]

In a new article published in The Cryosphere, the RESPONDER team reports how a channelised subglacial drainage system evolves and how discharge into Ikerasak Fjord affects melting the Store Glacier’s calving ice front. The team modelled the subglacial drainage network of Store Glacier in the high-surface-melt summer of 2012 and low-surface-melt summer of 2017, as[…]

The lake drainage event we documented in drone surveys has captured the attention of news papers. Here, you can see our work in Washington Post (www.washingtonpost.com).

A new paper from the RESPONDER team led by PhD student Tom Chudley has been published in the Proceedings of the National Academy of Sciences. In it, we present in situ records of a rapidly draining supraglacial lake in a fast-flowing sector of the Greenland Ice Sheet. Despite supraglacial lake drainage influencing ice sheet dynamics[…]

Sean Peters, Eliza Dawson, and Mickey MacKie from Stanford University deployed a number of different radar systems on Store Glacier. Sean experimented with passive radar using the Sun as a radio source for bed echo detection. Mickey, Sean, and Eliza tested a bistatic radar system developed by Nicole Bienert and Sean Peters during the 2018[…]

Here’s an update on how Cryoegg performed during the field season. We deployed it in the borehole at Store Glacier, but regrettably it was too large to reach the bed. The borehole is narrowest in the middle of the glacier where the ice is coolest, so this was where it got stuck, roughly 400m below[…]
