So satisfying when there’s such a stark contrast between the magnetic and non-magnetic grains coming from a single rock 🪨 🧲.

Said rocks are now crushed, and getting ready for cosmogenic dating (here’s one of them under a microscope 💎).

For #FieldworkFriday, here’s some footage from one of my favourite field days - collecting samples out by Denman Glacier, East #Antarctica. Wind howling, ice crystals piercing the air, and lovely quartzy rock (which we sampled using an angle grinder). Sound warning for those with headphones!

Next step: Feeding the rocks to Boyd (the rock/jaw crusher) 🪨💥🔨

The power of magnets 🧲!
Using a roll magnetic separator to divide magnetic and non-magnetic material from crushed up rocks.
(I’m looking for quartz!)

From boulder to Beryllium. The journey of a glacially deposited #Antarctic rock destined for cosmogenic dating 🧊🪨✨.
A whole lot of time in the lab, and no small amount of geochemical wizardry 🧙♂️. The past life of a glacier waiting to be uncovered.

It was also a great experience presenting my work on the past lives of the Denman and Scott Glaciers!

Just like that, #AARC24 has come to an end. It was great hearing all about rocks 🪨, ice 🧊, oceans 🌊, and all things #Antarctic 🇦🇶.
A great week learning from a fantastic community of researchers in the Antarctic gateway city of #Hobart!

Fantastic talk by @rsjones.bsky.social on Antarctica’s historical and prehistorical sea level contributions! Day 3 of #AARC24 off to a great start.

Almost halfway through #AARC24. Excited to be a part of such a large gathering of #Antarctic researchers. Looking forward to more great talks to come!

There’s something immensely satisfying about extracting quartz 💎 from crushed up Antarctic rocks 🪨.
See for yourself!
This quartz will soon be used for cosmogenic nuclide dating, and will give us insights into the past behaviour of a glacier!

Our work will put the Denman’s worrying trends of accelerating retreat into context, and shed light on the vulnerability of this mighty but at-risk glacier.

After being snowed in at the Bunger Hills ⛺️ we headed back out to the Denman Glacier for one last week on the ice, looking for clues (of the 🪨 variety) that will reveal the history of the glacier since the last ice age 🧊.

Check out this cool boulder, perched atop some smooth, glacially polished bedrock in East Antarctica 🧊🪨. It might have been left behind by a retreating glacier thousands of years ago (or more)!

We recently spent a week ⛺️ at Cape Jones alongside the Denman Glacier 🇦🇶, collecting cobbles and bedrock from the outcrop’s glacially scoured surface.
Our work will help uncover the past behaviour of this spectacular but retreating glacier 🧊🪨
