Tides Widen Ice Cracks
When icebergs calve off of Arctic and Antarctic coastlines, it affects glacial flows upstream as well as local mixing between fresh- and seawater. A recent study points to ocean tides as a major factor in widening the ice cracks that lead to calving. The team built a simplified mathematical model of an ice shelf, taking into account the ice’s viscoelasticity, local tides, and winds. Then they compared the model’s predictions with satellite, GPS, and radar data of Antarctica’s Brunt Ice Shelf, where an iceberg the size of Greater London broke off in 2023.
Between their model and the observation data, the team was able to show that the crack that preceded calving consistently grew during the spring tides, when tidal forces were at their strongest. The work gives us one more clue for refining our predictions of when major calving events are likely. (Image and research credit: O. Marsh et al.; via Gizmodo)

In fact, @OceanIceEU also has *lots* of cool modelling work too. This is a personal highlight (not my work! But going back to my PhD work, it's a long-standing interest) @IGE have implemented a new #iceberg #calving scheme in the #NEMO ocean model

Warmer oceans might cause #glaciers to break apart more quickly.
A 6.5-mile #crack formed in 2012 on Pine Island Glacier— a retreating ice shelf that holds back the larger West Antarctic ice sheet — in about 5 and a half minutes.
The rift opened at about 115 feet per second, or about💥 80 miles per hour.💥
This shows that under certain circumstances, an ice shelf can #shatter. It tells us we need to look out for this type of behavior in the future,
A #rift is a crack that passes all the way through the roughly 1,000 feet of floating ice for a typical Antarctic ice shelf.
These cracks are the precursor to ice shelf #calving, in which large chunks of ice break off a glacier and fall into the sea.
Such events happen often at Pine Island Glacier
— the iceberg observed in the study has long since separated from the continent.https://scitechdaily.com/the-80-mph-glacier-fracture-a-wake-up-call-from-antarctica/

The summer solstice is #Greenland's National Day
PILLUARIT!
Slightly unusually, the ablation season (net ice loss from melt) has yet to start in Greenland, surface melt is average for the time of year. Fresh snow is also still adding ice to the #IceSheet.
A start to the surface ablation season after the 21st June has only happened 4 times since 2000 - but was much more common in in the 80s + 90s.
Remember though - #ice is still lost by #calving of #icebergs -
And just like that we’ve #officially #started #calving #CowsOfMastodon

Underwater Tsunami Created By Collapse Of Antarctic Glacier’s Front End
The front end of #glaciers in #Antarctica that flow to the coast break apart due to melting, creating #icebergs. These are known as #calving events, and they can have dramatic consequences. Not only are large chunks of ice then free to move and reach lower latitudes, the process can also create powerful “internal #tsunamis” that profoundly alter the #ocean.
