The terminus of College Glacier in the Alaska Range, and the braided meltwater stream of College Creek draining into Phelan Creek and eventually the Delta River. The debris on the glacier surface is supraglacial moraine, rock that's been carried on top of the ice as the glacier moves.

Are you an MSc student looking for a thesis topic? Interested in Greenland/Antarctica atmosphere and ice sheet processes? Background in meteorology, geography, earth science or physics (or other quantitative discipline?

Then do I have the project for you...
I have just updated my list of open research ideas here:

https://sternaparadisaea.net/thesis-projects/

But I'm particularly at thsi stage interested in finding candidates to work on field data, satellite data, machine learning and parameterisation development and evaluation.

Why delaying climate action now means higher seas by 2100 – new research | The-14

Delaying climate action is accelerating sea level rise, increasing risks of coastal flooding, displacement and irreversible damage by 2100 worldwide.

Not all giant icebergs, or "megabergs," release fertilizing nutrients into the ocean as they melt; their capacity to stimulate marine life and absorb atmospheric carbon varies drastically depending on their individual life cycles and histories.

Not all icebergs are equal – and that matters for the climate, new study finds

As the world’s largest and most famous icebergs break up and melt in Antarctica, new research shows what impact they have on the ocean

A glacier table on the Black Rapids Glacier, Alaska Range. The boulder insulates the ice beneath it from melting, while the surrounding surface melts down, leaving it perched on a pedestal. Eventually, the pedestal becomes unstable, and the rock topples, and the process starts again.

Anyone have any clue where I can get a measuring tape for sea ice in Europe? The only supplier I have found is the very lovely and friendly Kovacs, but they are US based and the cost and time for delivery are crazy.
I mean one like this:

The Gabriel Icefall on the Gulkana Glacier, Eastern Alaska Range. About 400 vertical feet of ice in this frame. The striations are annual accumulation layers that become folded during flow. Towering seracs form where crevasses intersect as the ice is deformed over the steepening terrain.
