My god, when you think it can’t get any worse…

New research out today with colleagues Bishakhdatta Gayen and Andreas Klocker projects that the world’s strongest current, the Antarctic Circumpolar Current, may slow by 20% by 2050 in a high emissions future. So happy to have this out for the world to read!

What a lucky person having you as their supervisor @sophieiholland.bsky.social !

Apply for a PhD in Antarctic microbial ecology 🦠🇦🇶❄️ with me, @greening.bsky.social and @arcsaef.bsky.social. We're interested in multi-kingdom interactions in terrestrial Antarctica, including mosses 🌱 with @antarcticmoss.bsky.social. Details www.findaphd.com/phds/project.... Please share widely!

Don’t let anyone tell you this guy is popular or that the country is trending his way. Just isn’t true. Never was.

*New evidence of active subglacial lakes under the East #Antarctic Ice Sheet!*

We use #ICESat2 to show lakes fill and drain beneath slow-moving ice. Modelling likely meltwater routes suggests lakes discharge meltwater under ice shelves.

All NSF panels have been cancelled until further notice.

Kazmierczak et al present an efficient model that describes spatially and temporarily variable subglacial hydrology and geology, and their impacts on ice sheet flow in the ice sheet model Kori-ULB. This expands on a model I published last year. #ClimateChange #IceSheets 🧪🦣❄️ doi.org/10.5194/tc-1...

Summer over South Georgia. The glaciers pump millions of tonnes of sediments into the ocean which fuels a huge phytoplankton bloom sustaining one of the richest marine ecosystems on Earth. But as the glaciers recede and stop eroding, how long will this bounty last?

2025 really just a binfire of a start, eh

Likewise Andrew! Looking forward to seeing you again soon, either at Monash or in Hobart :)

With vehicle access into Somoveken Glacier limited by crevassing, the sensor deployment, survey and retrieval required a few 13-hour traverses, making for a unique Christmas Day & New Year’s Eve experience. Nevertheless, excited to be back home at @utas.edu.au & start looking at the data. 4/4

We also collected seismic data with a 32-node array at the Somoveken Glacier, hoping to detect cryoseisms from nearby crevasses & subglacial mechanisms. This was supplemented by active sledgehammer & phase-sensitive radar provided by @fsmccormack.bsky.social to constrain ice & bed structure. 3/4

As part of the GRIT (Geophysical Research InfrasTructure of Antarctica) initiative, we installed two new long-term seismometers alongside the Sigyn Glacier, aiming to collect passive seismic data for several seasons. These stations provide new data points for continental solid-Earth studies. 2/4

First post on BlueSky to mark the end of my Antarctic fieldwork in Queen Maud Land working with @andrewmackintosh.bsky.social and some other wonderful scientists at @arcsaef.bsky.social. Overall, trip was hugely successful, with some exciting science to come. 1/4
