Published: “Termini of calving glaciers as self-organized critical systems”
Our paper on the extreme sensitivity of calving termini is now out in Nature Geoscience. A press release describing the significance of our work is available here.
New perspective on calving in press at Nature Geoscience
A new study, of which I am a co-author, examines globally-collected observations of iceberg calving and novel model results to present a new framework for understanding this important mass loss process. Our study explains why calving rates vary so greatly … Continued
Watch a presentation of my research
I recently presented an overview of my research program to date at the weekly seminar of the Univ. of Texas Institute for Geophysics. You can view it here. In this talk, I describe my past and ongoing research into how … Continued
An extraordinary field season
Earlier this month, our joint Univ. of Texas and Univ. of Kansas team returned from West Greenland, where we collected data regarding the behavior of ocean-terminating glaciers in a major fjord system.Many of the sensors we visited, including GPS receivers, … Continued
Preparing for AGU
At the annual meeting this December, I’ll be making an invited presentation and co-convening a different session. On behalf of AGU’s Cryosphere focus group, I am serving on the meeting planning committee.The fall meeting of the American Geophysical Union is … Continued
Understanding iceberg calving
I’ve recently co-authored an accessible review of recent research into iceberg calving. You can read it by clicking here. Approximately half of the ice loss from the Greenland Ice Sheet occurs where glaciers flow directly into the ocean. At the … Continued
Going to sea to study glaciers
I recently joined the UT Marine Geology and Geophysics field course on the Gulf of Mexico to learn about methods to study the seafloor. When deployed at the fronts of glaciers, these techniques can help us identify the stability of … Continued
New technology for understanding glacier motion
This week, I’ve been in Fairbanks learning how to use radar to gain an unprecedentedly sharp view of glacier motion. We’ll be deploying this technology in Greenland this summer.While camping at the terminus of Rink Isbrae (71.5 degrees N) for … Continued
Understanding tidewater glacier change in Greenland
A very nice summary of the main project I am working on has just been published here. With interviews and photos, Marcy Davis describes the goals for our work and the methods we’re employing to learn about the glaciers and … Continued
Anticipating new data
Since arriving at UTIG in January, I’ve been continuing to explore how seismology can inform us about glacier behavior. Now, with the summer field season approaching, colleagues and I are preparing to return to Greenland and recover a year’s worth … Continued
