🚨 Our new preprint!
*Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions*

🔗 doi.org/10.22541/essoar.175285257.77669558/v1

In 2021, giant icebergs hit Dronning Maud Land ice shelves in #Antarctica, causing a chain reaction of calving & major regional ice-shelf area loss. 💥

Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions

Iceberg calving accounts for about half of Antarctic ice-shelf mass loss. We used satellite imagery to analyze annual ice-shelf front changes and major calving events over eight years from austral sum...

Icebergs? The size of a city? 90 miles from the UK? Must be a joke, right?

No! Our new paper in @natcomms.nature.com shows massive tabular icebergs broke off the UK in the last ice age before the UK’s ice shelves disintegrated from climate warming.

I use ICESat-2 for detecting lakes under Antarctica. Local ice surface uplift and subsidence shows us where lakes fill and drain over multiple years.

This is important to understand how meltwater moves & its release under ice shelves. An amazing data source from @thenasaearth.bsky.social! 🛰

Helen Amanda Fricker @helen-amanda.bsky.social · Mar 15

ICESat-2 fired its TWO TRILLIONTH laser shot last weekend, and it hit off the coast of East Antarctica, right by Australia’s Casey station! Yay for @thenasaearth.bsky.social and all the incredible satellites we have monitoring planet Earth for the benefit of humanity…
