Preparing a breakfast talk for the research group @dmidk this morning and I'm reminded just how good (in a slightly bleak way) this #satpic animation showing #Antarctica's #IceShelves in retreat...

Now for @climate_clara on #neuralNetworks to simulate basal ice shelf melt over #Antarctica's #IceShelves

How much do #Antarctica #IceShelves melt? And what is driving those melt occurrences? That's the question our latest paper is trying to answer.

Now (finally!) out #OA in Journal of #Climate

For those registered to #EGU23 note that CR3.4 will be held this afternoon and tomorrow morning on #IceShelves and tidewater glaciers!

A new twist on an older idea: a temperature threshold for #Antarctic #IceShelves
But @jmvanwessem @steflhermitte et al show #Snow is key:

Variable temperature thresholds of melt pond formation on Antarctic ice shelves

"For relatively wet ice shelves, the −5 °C temperature threshold was confirmed; but cold + dry ice shelves such as Amery, Ross + Filchner-Ronne are more vulnerable than previously thought, with threshold temperatures well below −15 °C. "

"Researchers have discovered a process that can contribute to the melting of ice shelves in the Antarctic."

"An international team of scientists found that adjacent ice shelves play a role in causing instability in others downstream."

#Antarctic #IceShelves are not just smooth, perfect slabs of floating #Ice, but rather contain areas of damaged ice that affect their strength and flow.

Building on previous work, Maaike Izeboud & Stef Lhermitte show how their "NeRD" method can detect different types and scales of damage (e.g. crevasse fields, large rifts, shear zones) in both SAR and optical #RemoteSensing datasets.

Staying with #Antarctic #IceShelves - I also found I had revisited this super cool paper by the awesome #DrGilbz (#EllaGilbert) and Christoph Kittel on the likely futures of the peninsula shelves under different warming scenarios..
tl;dr - limit the warming to save the shelves..

Hello world, it's time for an #Introduction and my first-ever toot 🐘

I'm an #Antarctic researcher 🇦🇶 and #PhD candidate working at Monash University as part of the SAEF research programme.
My work focuses on #Ice - #Climate interactions, and particularly the processes behind #Melt on #IceShelves in #EastAntarctica.

Away from #Research, I enjoy #Reading 📚, #Walking 🚶‍♂️, #Cooking 👨‍🍳, #Photography 📸, and working through the Rolling Stone's 500 Greatest Albums of All Time list 🎵
