Parker et al provide a revised model of the ice sheet margin retreat of the Ross Sea sector of Antarctica. They show there was a rapid retreat of ice shelf between about 6900 and 5400 years ago.

IceClimate@pixelfed.social - Wasa station. After a morning of safety training and snow scooter training, we unpacked and I took our snow optical sensors for a walk to test the surface snow grain sizes. All present and correct.
A good view from the moraine over the station and the vast whiteness of the #iceSheet beyond.

Next week our ECR group are starting a #MachineLearning sprint to speed up the development of our new #IceSheet surface mass budget emulation models.
I'm looking for hints, ideas tips and inspiration to help smooth and accelerate the process.
If you're used to working in #Sprint mode, what in your opinion makes it work or otherwise hinders it?
What can I as supervisor do to make it run better?
And how should we celebrate it's conclusion?
Also, should me do an #AMA on the process?
These happenings remind me strongly of a gripping novel I once read, making me shiver and think about my own consuming of resources:
The Sands of Sarasvati (Sarasvatin hiekkaa), in German Die Schmelze (The Melting)
by Risto Isomรคki, scientific editor, environmental activist and author.
The novel is about scientists discovering huge lakes and rivers underneath and in the #Greenland #icesheet threatening to break loose.
If one wants to get the feeling how global #ClimateCatastrophe is threatening the earthly world as we know it now this is a strongly recommended read.

Our new study shows that the #WestAntarctic #IceSheet repeatedly crossed #TippingPoint thresholds in the past, with important implications for its future stability.

Study: collapse of #WestAntarctic #IceSheet could be triggered with very little #OceanWarming above present-day, leading to 4 metres of global #SeaLevelRise to play out over hundreds of years.

Incidentally, while this is happening in the US, we have been working quite hard on the @polarportal (well @MartinStendel + out @dmidk colleagues have, I've mainly tried to make helpful comments), the old website is still up giving the latest on #Arctic #seaice #Greenland #icesheet and other datasets, but there's some fancy new stuff on the pipeline.
