#glaciology

I really enjoyed @Felienne's narrative about narratives about Computer Science yesterday. She applied some of the ideas presented in the Glaciers, Gender and Science paper (https://journals.sagepub.com/doi/abs/10.1177/0309132515623368) to her experiences in the Computer Science / Programming Languages communities. She's also starting a reading club to brainstorm the meaning (and the name?) of the field of "Computer Science".

Slipping Ice Streams

The Northeast Greenland Ice Stream provides about 12% of the island’s annual ice discharge, and so far, models cannot accurately capture just how quickly the ice moves. Researchers deployed a fiber-optic cable into a borehole and set explosive charges on the ice to capture images of its interior through seismology. But in the process, they measured seismic events that didn’t correspond to the team’s charges.

Instead, the researchers identified the signals as small, cascading icequakes that were undetectable from the surface. The quakes were signs of ice locally sticking and slipping — a failure mode that current models don’t capture. Moreover, the team was able to isolate each event to distinct layers of the ice, all of which corresponded to ice strata affected by volcanic ash (note the dark streak in the ice core image above). Whenever a volcanic eruption spread ash on the ice, it created a weaker layer. Even after hundreds more meters of ice have formed atop these weaker layers, the ice still breaks first in those layers, which may account for the ice stream’s higher-than-predicted flow.

Paper sent to co-authors for final comments. Aiming to submit by Monday. And now it's time to go home.

Have a photo of some ice melange (Because that's what I've been working on this evening...)

Excellent episode of Science In Action.

Thoughtful + alarming on #H5N1 but piece on self regulation by genetic scientists was super interesting:
#glaciology is also having this discussion, now on #geoengineering. Time for a new #Asilomar?

Ice (Glaciology )

Ice is water that is frozen into a solid state, typically forming at or below temperatures of 0 °C, 32 °F, or 273.15 K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. Depending on the presence of impurities such as pa...

In case all the interest in #Greenland has raised your interest in a new job, our ace collaborators in #Asiaq, the logistics and survey organisation are currently recruiting a #climate + #cryosphere position.
This is a *permanent* position and a super opportunity to work on some really exciting data, as well as on both @horizoneu and @esaclimate type projects.
We have a long-running collaboration with Asiaq, so you may even end up trying to avoid me in the office...

Measurements from land-based instruments and airplane-mounted radars in Greenland’s far northeast reveal the extent of ice loss experienced by the 79° N-Glacier. The Alfred Wegener Institute’s findings indicate that the glacier’s thickness has reduced by over 160 meters since 1998...

Another cold frosty morning but the big freeze is lifting in Copenhagen slowly. It's a perfect #icetodon moment as this morning I'm off to the Danish #GreenlandIceSheet seminar to talk about this place among other things: #DMI's geophysical facility in #Qaanaaq NW #Greenland where we're putting together an intensive #glaciology programme...

In a pub quiz a couple of days ago my answer regarding the largest glacier in Europe was marked as wrong because according to Google the Vatnajokull Ice Cap is a glacier . So, Mastodon #glaciology experts, what is the largest individual glacier in Europe?

Photographe, philosophe et glacio-spéléologue, Jean-François Delhom explore en images et en mots la beauté des grottes glaciaires, entre l'impermanence qui les lie au mouvement des glaciers et la menace que le dérèglement climatique fait peser sur leur existence même.
