We have a new logo! This is the work of our logo design competition winner Dr Thomas Arney. It represents a modernised and updated version of the old logo we all know and love with the double meaning of the rainbow showing our support for the LGBTQ+ community as well as representing spectroscopy!

New paper out now in EPSL! Pb isotopes and Rb–Sr geochronology via laser ablation of feldspar grains from West Antarctica. This developing method with some added ML clustering spice exposes crustal fragments, tectonic boundaries and metamorphic events hidden under the ice.

West Antarctic subglacial geology distinguished by Pb isotopes and Rb–Sr ages in ice-rafted feldspars

Multi-proxy fingerprints via Rb–Sr isochrons from detrital Pb-isotope populations reveal Antarctic geology and set the stage for future studies of ice sheet history.

Ever wanted to see how a coral skeleton grows? In this paper (led by: @jtrendbio.bsky.social) www.sciencedirect.com/science/arti... we use Live CT, a method of scanning live organisms using microCT, to visualise how the skeleton grew over about one month.

I will forever be haunted by this footage. Trawling has only been filmed underwater a few times in documentary history, and never with such clarity. What’s so heart-rending about these shots is watching how the animals don’t just get swept up — they swim for their lives. 🌎🦑🧪

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. 🧵 www.nature.com/articles/s41... @bas.ac.uk

Change in iceberg calving behavior preceded North Sea ice shelf disintegration during the last deglaciation - Nature Communications

Massive tabular icebergs broke off of the UK during the last ice age. The widespread break-up of the ice shelves which produced these giant icebergs can be traced to around 18,000 years ago, and likel...

This is great, I would have loved to take this! I hope it will involve the whole Earth system, not just ecology. If 16 yr olds leave with the idea that it's all connected in one beautiful complex web – biosphere, atmosphere, oceans, climate – it will have done a great service.
