#OnThisDay in 1872, the expedition of HMS Challenger set sail from Portsmouth, travelling nearly 70,00 nautical miles and cataloguing over 4000 unknown species over 4 years. This pioneering expedition, organised by the Royal Society, laid the foundations of oceanography.

New national climate plans have barely moved the needle on limiting global warming. Yet there is hope. According to UNEP's latest #EmissionsGap Report, accelerated adoption of renewable energy and falling costs mean we have the tools to cut emissions now: www.unep.org/news-and-sto...

New paper published today by PhD student Théo Picard who used machine learning to explore what controls the variability of deep ocean particle fluxes collected by PAP site sediment traps, which highlighted the importance of interior ocean dynamics on sinking particle trajectories.

And it's over! #LiegeOcean25. Thank you everyone for coming and for the nice discussions. I have certainly learned a lot about marine CO2 removal this week. Have a nice trip back all!

🌊 A great + insightful week so far at #LiegeOcean25 focused on mCDR emerging views and challenges. Today I presented on a #sociooceanography workshop session where we trialled developing storylines as a way to comprehensively anticipate environmental + societal outcomes of an imagined mCDR trial

Captured some unusual clouds over Southampton early this morning. Does anyone know what could cause them to form like this? Googling hasn't turned up much... ☁️

About ten days left for this job! Don't miss the chance!

Javier and Sandy introduce their #MarineCarbonDioxideRemoval (#mCDR) session at 2025's #SocioOceanography workshop at @noc.ac.uk - very much looking forward to our discussions over the next couple of days! (Especially the bits on Spiderman!) #InterdisciplinaryResearch 🌊

While I'm here ... Before we get too complacently dismissive over in open ocean world, we shouldn't forget that our own carbon cycle house isn't always entirely in order either. I've often heard the #BiologicalCarbonPump talked-up to quite an extraordinary degree given the scale of its actual role.

Not quite a new publication, but a new @bsky.app post from my NOC colleague @stephhenson.bsky.social on a really nice model-based-but-observation-driven study that she led quantifying the #BiologicalCarbonPump ... 🌊

My pleasure @fiona-gell.bsky.social! This was my Christmas break read of 2023… highly recommend it! If you want to read my review you can find it here: www.challenger-society.org.uk/oceanchallen...

It’s interesting that the emojis show the earth from three angles 🌎 🌍 🌏 but not the fourth. Though 🔵 is a fair approximation of what it would look like. People underestimate the Pacific.

Scientists, academics, researchers: We’re excited to share that @altmetric.com is now tracking mentions of your research on Bluesky! 🧪

🌊 Delighted to see this new paper led by PhD student Jack Williams out in Nature Geoscience - it’s been a fun journey bringing two project datasets together (COMICS and CUSTARD) to show that diatoms are not always as efficient at transferring carbon as we thought! www.nature.com/articles/s41...

Heading to the University of Liverpool today to give a seminar on a recent paper I co-led with Antony Birchill on Southern Ocean hydrothermal Fe and Mn transport. Looking forward to catching up with Liverpool colleagues and always nice to be back on home turf! www.nature.com/articles/s43...
