Mountain enthousiast. Scientist of the ocean, ice, climate variety. Crafter. Based at the British Antarctic Survey. Views my own.
Another favorite quote: "the greatest danger to our future is apathy."
Thank you for being the first woman scientist I looked up to as a kid and for spreading curiosity and hope.

My favourite Jane Goodall quotes....so many, so to the point, so wise. How different the world would be if enough people listened to her.

Autumn is in full swing in the Lake District! Chanterelles, hedgehog mushrooms, boletes, amanitas and more.

![Comic. [Two people on shore looking at body of water] PERSON 1: Hey, where’s that big island we were looking at this morning? PERSON 2 with short hair: Oh, it’s underwater. The ocean’s depth here goes up and down by like ten feet every day. PERSON 1: What? PERSON 2: It’s because the planet has a big moon orbiting near the surface. It causes weird gravity effects. PERSON 1: *What???* [caption] People here are used to them, but tides are one of the weirdest and most sci-fi elements of life on Earth.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:cz73r7iyiqn26upot4jtjdhk/bafkreidj2tdqhkgoamiqf5reqt7kvbpt26x3cgjxsp4rtwwb46qumcltdq@jpeg)

Watch the seismic waves from the magnitude 8.8 earthquake off the coast of Russia sweep beneath seismic stations in North America.
By the time the waves reached North America, they are far too small to be felt by people, but can still be detected by seismic instruments. 🧪

Greenland (Kalaallit Nunaat) and Baffin Island (Qikiqtaaluk) from the sky on the way to North America. Who could sleep when there's an ice sheet, coastal glaciers, and sea ice floes to stare at!

This is horrible. I don't even know what to say. Some of our most key polar data.

Happy to share that the final chapter of my PhD is published! 🥳
We built an ocean Pb model and:
(1) Identified the continued impact of pollution on Pb concentrations in the western Arctic Ocean
(2) Traced pathways of warm Atlantic Water in Baffin Bay and onto the West Greenland shelf using Pb.

It took me more than 10 years but today I was in a meeting of entirely female ice-ocean modellers (4) for what I believe is the first time

Pine Island Glacier accounts for a large proportion of recent Antarctic ice loss. This 7.5 year animation from Sentinel-1 shows the weakening of the lateral margins and the stochastic nature of the calving process. Grab a full-screen version here: aluckman4.wixsite.com/ade-s-world-...
