🌊❄️ When Antarctic glaciers collapse into the sea, they can trigger huge underwater tsunamis that mix the ocean, affecting ice loss, climate and ecosystems. The project I lead on this is now in the field and featured on Sky News: news.sky.com/story/underw... #Antarctic #OceanMixing #ClimateScience

Le prix #SciencesDeLaTerre et #Climatologie du concours photo #RSPPhotoComp 2025 a été décerné à Michael Meredith @oceanandice.bsky.social pour sa photo prise lors d'une expédition hivernale dans la baie de Börgen en Antarctique, montrant les projecteurs du navire qui éclairent le glacier William.

A picture is worth 1000 words... This appeared on the BBC News today, showing the increase in solar electric generation in the UK. Not sure who produced it, but genuinely think this is a genius piece of scientific communication - the construct and choice of colour scale is near-perfect. Chapeau!

Delighted that one of my Antarctic winter photos has won the 2025 Royal Society Photography Competition, Earth Science & Climatology category. Captured during polar-night surveys of ocean conditions near Antarctic Peninsula glaciers. royalsociety.org/journals/pub...

Heading home now, after an awesome week in Hobart! So much great Antarctic science happening here. Also: lovely people. Shame they’re so darn good at cricket 🏏

Hello Hobart! Excited to be visiting, to give a talk at the Institute for Marine and Antarctic Studies, and a keynote at the @ACEAS annual meeting. Should be a great week (and the weather is amazing!) @antarcticsciaus.bsky.social @utas.edu.au

Some people steal paper clips from the stationary cupboard… others think bigger… 😉

Two stories juxtaposed on the BBC website... sigh. Anyone else spot the irony here?

I am co-convening a meeting at the Royal Society later this year, with @krhendry.bsky.social and other very excellent polar science colleagues. If you have interests relating to Antarctica and the impacts of climate change, please consider participating!

Recommended listen: Scientists at the University of Cambridge, including Prof Michael Meredith ( @oceanandice.bsky.social ), discussed on The Naked Scientists podcast how the latest polar science is tracking climate change’s impact in Antarctica.

Some personal reflections, at the end of a remarkable expedition... we've seen amazing things, and experienced Antarctica in the depths of its dark winter. We're returning home with an unparalleled dataset, and a deeper appreciation of this awe-inspiring place. www.bas.ac.uk/media-post/r...

Happy Midwinter from Antarctica! We spent it at Elephant Island, where Shackleton and his men were marooned before their incredible escape and rescue. A privilege to be here at this time of year.

Last night we were breaking through sea ice, in the dark, in blizzard conditions. My respect for the skill of the officers and crew of the ship just reached a new level…!

📢 New paper alert! 📢 New insight into how sea ice controls the ocean uptake of carbon dioxide around Antarctica, obtained from the unique year-round Rothera Time Series. Delighted to be part of this study, led by the very excellent Elise Droste. 🧪❄️🥼🌊 www.nature.com/articles/s43...

👏🏽 Kudos to all the authors of this new book on Antarctica and the Earth System, including INSTAARites Cassandra Brooks & Sharon Stammerjohn. They are both chapter lead authors!

A @bas.ac.uk tradition... when the ship departs Rothera Research Station for the last time, the winterers remaining on base light flares to bid us farewell. They will now continue their science and activities on base throughout the winter, while we proceed back to sea to continue ours. 🧪❄️🥼🌊

Rothera Research Station looking amazing in the moonlight, with a hint of a dawn...

Apple Watches are amazing gadgets, and can tell you the time of sunrise and sunset for wherever you are in the world... this time of year in Antarctica, the calculation is relatively simple.... 🤣 🧪🌊🥼❄️

Check out our latest and greatest on Antarctic glacial melt and its impact on marine life, led by the awesome Jack Pan! Perfectly-timed publication, given that I'm currently in the Antarctic gathering more data on these things.....!! www.nature.com/articles/s43...

Conditions in the Antarctic winter can be pretty hostile, but science continues... this is deployment of an instrument that is lowered to just above the seabed, and gives us data on ocean temperature, salinity, oxygen content, and other important variables. 🧪🌊🥼🌊

Our Antarctic expedition is hitting the screens today - ITV News coverage throughout the day, and for the next 2 weeks! Great that we can bring such important science to the public - huge thanks to Martin Stew, Mike Field and the ITV team for enabling this. www.itv.com/news/2025-06...

Happy #WorldOceanDay !! Down here in Antarctica, we will spend it measuring the ocean and sampling the sea floor, to understand better how ice loss is impacting climate and ecosystems. The views continue to amaze…! 🧪❄️🥼🌊

With such short days, the Antarctic sunrises and sunsets start to merge into one... yesterday's was spectacular.... Another week or so, and the sun will not rise at all. 🧪🥼❄️🌊

Some people asked me why I wanted to work in Antarctica in winter.... 🧪🥼❄️

The days in Antarctica are shrinking rapidly, and in just a few days the sun won't rise above the horizon at all.... 🧪❄️🥼🌊

We're using our ever-dwindling daylight to look for wildlife here in Antarctica... yesterday we saw dozens of humpback whales, sometimes accompanied by bonus penguins....! 🧪❄️🥼🌊🐳🐧

The view inside Börgen Bay, Antarctica. We are collecting water samples to understand how glaciers and the ocean influence each other in winter. 🧪🌊❄️🥼

Visiting the very excellent Palmer Research Station, on the Antarctic Peninsula. A great opportunity to support and progress collaboration with US researchers, who are key scientific partners. They are doing critical work here on climate change, ecosystems, and a host of other issues. 🧪🌊🥼❄️

We push southwards into the dark Antarctic night, the ship's searchlights picking out insane swirls of snow in a blizzard... @bas.ac.uk 🧪❄️🥼🌊

Spectacular views flying over the Andes…. heading South to Antarctica…. 🧪🌊❄️🥼

Guess where I’m heading today….! Excited for a winter expedition to Antarctica. (Forecast was from a few days ago; I’m hoping it wont be quite this cold…though the chance of sunshine is kind of small this time of year…!🤣) Wish me luck…! 🧪❄️🥼🌊

Personally, I welcome our new abyssal overlords.....

People sometimes think of Antarctica as being barren and devoid of life, but the ocean surrounding the continent is incredibly rich with wildlife and biodiversity. Photos of new discoveries and insights from our wonderful Australian colleagues… 🧪🥼❄️🌊🦑 www.theguardian.com/environment/...

Thanks Amazon for the recommendation....! 😆 Can't shake the feeling I may have read this one already though... 🤔

I’ve been girly swotting. A 🧵 on #penguins for #WorldPenguinDay

Happy #WorldPenguinDay!! To help celebrate, here is a picture of two Adelie penguins, which I took at the @bas.ac.uk Rothera Research Station a few years ago. I liked the yellow-tinge of sunset in the background. Enjoy 🐧 !! 🧪❄️🥼🌊🐧

Put together by the @bas.ac.uk , we recommend taking a moment this earth day to purchase this book and learn a little about our global inter-connectedness for better and for worse.

Happy Earth Day! 🌍 Delighted to present this new book all about Antarctica. 🇦🇶 I was coauthor on Chapter 7 led by Ben Galton-Fenzi. Congratulations to the many other authors involved and to @oceanandice.bsky.social for leading us all! 🌊

Congratulations to all the editors for bringing everyone together and producing such a beautiful book, just in time for #Earthday - a big thanks to @oceanandice.bsky.social for keeping us all on track - really enjoyed being part of this!

New book!! 📕 Antarctica is intimately connected to the rest of our planet, affecting climate, ecosystems, cultures and society. Our new book draws together international experts to explore this influence, and to understand what humans are doing to Antarctica (1/n) www.routledge.com/Antarctica-a...

Last night, a magnificent vulpine visitation…! 🦊

Colossal squid captured on camera!! Amazing work by @drmtaylor.bsky.social and team. 🧪🌊🦑 www.bbc.co.uk/news/article...

Check out our latest paper, in @naturegeosci.bsky.social - led by the awesome Tasha Lucas...! New insights from autonomous robots into how megabergs impact the ocean and the life within it... @bas.ac.uk 🧪🌊🥼❄️ www.bas.ac.uk/media-post/u...

The big question is - will the penguins now impose reciprocal tariffs? www.theguardian.com/us-news/2025...

What is the travel advice for climate scientists planning trips to meetings in the US? Should we not try? www.theguardian.com/us-news/2025...

Incredible work from @ptfretwell.bsky.social, Hamish Pritchard, and the Bedmap team...! So much depends on the topography beneath the Antarctic Ice Sheet, including the future of sea level rise across the planet - and this new work will really help us understand and prepare. @bas.ac.uk 🧪🌊❄️🥼
