The press release for our recent JGR: Earth Surface paper. A nice description about our project and the laser scanners
For nearly a decade, @PennSAS glaciologist Leigh Stearns and collaborators have aimed a laser scanning system at Greenland’s Helheim Glacier. Their survey is reframing the understanding of how ice loss contributes to sea-level rise.

We have a new paper out! Work with @leighstearns.bsky.social, @laserglaciers.bsky.social, and Sid Shankar studying the potential of new ICEYE SAR satellite imagery to study the dynamic behaviour of ice mélange around the margins of the Greenland Ice Sheet.

Calving Mechanisms Inferred From Observations of Surface Depressions at Helheim Glacier, Greenland
Surface depressions on Helheim Glacier appear at a consistent location on the lee side of a subglacial ridge and have increased in frequency
Observed calving episodes, regardless of calving style...

Greenland's fjords are the gateways via which the ice sheet interacts with the open ocean. A large fraction of all the ice calved from the ice sheet melts within these regions. Kinne et al., explore how all this melt affects fjord circulation 🌊 🐻❄️

This comes on top of the quiet discontinuation of the NSF OPP program earlier this year. We are going to lose so many talented early career scientists as a result of these short-sighted decisions.

NASA Earth data + AI enable us to infer the constitutive models critical for ice dynamics. AI is useful, but no data = no discovery. Below is an example of the training data: a velocity map showing the dynamics of the Antarctic Ice Sheet. Source: #NASA.

what a great paper! This really complicates seasonal tidewater glacier variability, which is already complicated 😵💫

A lot of our academic colleagues go to work at NSF for a couple of years as a rotator. In the programs that have funded me, rotators have been essential to keeping those divisions going. It's hard to see how these firings won't severely diminish NSF.
Firings at the NSF included permanent employees who had already completed their one-year probationary period, as well as at-will workers.
