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.

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

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.
