Another exciting PhD opportunity with @isobelyeo.bsky.social, me and others on Mapping Hydrothermal Fluid Flow in Earth’s Most Explosive Volcanoes… www.findaphd.com/phds/project...

It was a huge privilege to contribute to this plan for the future of marine science infrastructure and the final report is a huge community effort. The UK have long been world leaders in marine hazards research and long may it continue!

Come do an exciting new PhD project with fieldwork in the Caribbean and S Pacific working on understanding what happens when powerful lahars enter the ocean - with me, @isobelyeo.bsky.social at @noc.ac.uk www.findaphd.com/phds/project...

Was great to spend a day with INGV looking at lahar and debris avalanche deposits on the slopes of Mt Etna and discussing land to ocean transport processes. Really inspiring to see these deposits in the field with local experts!

Great to see @mikeaclare.bsky.social @noc.ac.uk quoted in this piece in the Guardian today www.theguardian.com/news/2025/se... about the Hunga Volcano eruption and the subsequent telecommunications outage in 2022.

www.nationalgeographic.com/science/arti... Interesting article on the 2025 Santorini seismic crisis in Nat Geographic w quotes from @isobelyeo.bsky.social and others discussing the excellent new Nature paper by Jens Karstens, Marius Isken & co

Get your abstracts in and get registered for VMSG 2026 in Southampton! It’s going to be a great event with some excellent workshops across a range of topics @vmsg.bsky.social

Seminar 3 recording: @mikeaclare.bsky.social (NOC, UK) on offshore hazards caused by lahars 🌋🌧️ entering the ocean. www.youtube.com/watch?v=LDVe...

Awesome fieldwork in the UK Lake District seeing welded ignimbrites, subaqueous volcaniclastic density current deposits, autobreccias & lots of soft sediment deformation in and around ancient caldera fill sequences. Scoping future ideas with @isobelyeo.bsky.social @noc.ac.uk @vmsg.bsky.social

Amazing talk by @isobelyeo.bsky.social bringing together loads of collaborative research on volcanic hazards from the 2022 Hunga eruption and what we can tell from the deposits left behind at @iavcei.bsky.social @ukri.org

A really great end to this lahars focussed mini session at @iavcei.bsky.social by @mikeaclare.bsky.social from @noc.ac.uk presenting work on lahars offshore and their huge sediment loads funded by the Sustainable Blue Economies Program.

Our new paper on volcanoes and the subsea cable network, led by @mikeaclare.bsky.social, is out today in Bulletin of Volcanology. Get it here: link.springer.com/article/10.1...

Excellent talk by @isobelyeo.bsky.social at SubOptic25 in Lisbon talking about how to enhance the resilience of small islands telecoms infrastructure to natural hazards, after she convened an interesting session on Marine Operations @noc.ac.uk

Really pleased to see our paper out assessing volcanic hazards for subsea cables and what we can learn from instances of damage dating back to the 1883 eruption of Krakatau that cut a critical telegraph cable and up to the present day

A great second day at SubOptic 2025, including a fascinating talk by @mikeaclare.bsky.social @noc.ac.uk on the challenges of cable fault attribution and how hazards are not always coincident with events.

Do you have a passion for marine geohazards and want a permanent job? Join us!

Check out an excellent interview with @isobelyeo.bsky.social @noc.ac.uk on BBC Radio 5 discussing recent eruptions at Axial Seamount, how new crust forms at mid ocean ridges, and a need to monitor submarine volcanoes -from 02:49 onwards www.bbc.co.uk/sounds/play/...

Nice discussion of our paper led by Harya Nugraha in The Conversation on large submarine landslides and how some can grow much larger due to erosion, and summarising the relevance for Indonesia theconversation.com/longsor-bawa... Original paper in GEOLOGY pubs.geoscienceworld.org/gsa/geology/...

Listen to the much more fun than me @sofiadellasala.bsky.social from @oxuniearthsci.bsky.social talking about our Santorini expedition and her packing challenges here.

Really enjoyed being interviewed on @bbc5live.bsky.social this afternoon about @noc.ac.uk led @ukri.org funded work on submarine volcanic eruptions. If you want to hear more about underwater robots and my secret lair then give it a listen from about 2hrs 13 minutes in. www.bbc.co.uk/sounds/play/...

New paper led by Ricarda Gatter of MARUM shows the value of micro-CT scanning, revealing surprisingly fine-scale porosity changes which has wide application to landslide & subsurface fluid flow assessments. Based on work started at @noc.ac.uk in 2020 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

If you’re interested in knowing more about our work in Santorini here is me talking for two and a half minutes about what we’ve been doing and hope to achieve. Put together by our magnificent Comms Team and filmed by the brilliant Dan Bourne. m.youtube.com/watch?v=6jFc... @noc.ac.uk @ukri.org

Great to see this research covered by the BBC - looking forward to seeing what we discover from all the data that were collected last month! Nice work by @isobelyeo.bsky.social on radio and TV interviews!

Our new paper shows what happens when a major glacial lake outburst reaches the ocean, led by Lewis Bailey and supported by @ukri.org @noc.ac.uk

Pleased to have contributed to this new report published by UNEP-WCMC that looks at the interactions between subsea cables and the marine environment and opportunities for collaborations between industry and research www.unep-wcmc.org/en/news/keep... @noc.ac.uk

Sediment flows from 2022 Hunga eruption travelled >100km to the west, entraining more sediment - revealed by ROV dives, sampling & detailed sediment analysis. New paper led by Marcus Chaknova at UninOregon w @isobelyeo.bsky.social @noc.ac.uk & more agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Great to see this paper out based on data acquired by @ukri.org funded research, showing how turbidity currents transport and concentrate microplastics in the deep sea

The @ukri.org HYDROMOX cruise has come to an end. What a mammoth project @isobelyeo.bsky.social pulled together, I am so grateful to be part of the team that has successfully explored the hydrothermal systems at Santorini and Kolumbo and I can't wait for the science that will come of it!

Absolutely remarkable work by the crew for making this happen! And orchestrated impeccably by @isobelyeo.bsky.social - a very complicated operation indeed

Saw my first hydrothermal chimney today at Kolumbo Submarine volcano as part of the @ukri.org HYDROMOX project led by @isobelyeo.bsky.social, loved seeing what I have been reading about for the last 2 years with my own eyes!!

Sampling hydrothermal mounds on the seafloor of the Santorini caldera as part of the @ukri.org HYDROMOX project to understand the fluid flow that feeds them @isobelyeo.bsky.social @sofiadellasala.bsky.social @gemmaportlock.bsky.social @noc.ac.uk

It’s a beautiful day for sampling the fluids that circulate through a volcano with the @noc.ac.uk ROV Isis. @ukri.org

On International Women’s Day I’d like to take the opportunity to highlight women’s contributions to this project and marine science. This expedition couldn’t run without our geophysicists, geologists, ROV pilots and crew, many of whom are women. They’re inspirational. @noc.ac.uk

ROV dives, gravity coring, geophysical surveys and getting ready for fluid sampling on board the RRS Discovery - it’s been busy inside the Santorini caldera on the @ukri.org HYDROMOX project today! @noc.ac.uk @isobelyeo.bsky.social @gemmaportlock.bsky.social @sofiadellasala.bsky.social

First core on deck during the HYDROMOX expedition in the Santorini Caldera!! Was amazing to understand how the samples go from the seafloor to the lab bench @mikeaclare.bsky.social

I am on my first ever fieldwork expedition! My PhD focuses on the hydrothermal system in Santorini, working with @davidmpyle.bsky.social. We have lots of exciting operations on HYDROMOX @ukri.org that will gives us a better insight into Santorini's caldera seafloor

Excited to be offshore to see the first seafloor instruments being deployed as part of the @ukrio.bsky.social expedition offshore Santorini as part of the HYDROMOX project led by @isobelyeo.bsky.social @noc.ac.uk

Cold but productive day sampling fluids from hot springs on the Kameni Islands to complete characterisation of hydrothermal circulation in this amazing volcano for the @noc.ac.uk @ukri.org HYDROMOX project. Couldn’t have asked for a better field team @gemmaportlock.bsky.social and Dr Katie McFall.

The @noc.ac.uk @ukri.org HYDROMOX project will be in Santorini with RRS Discovery next week, helping to measure seismic activity nearby and investigating fluid circulation at this incredible volcano. Before that, we’ve been sampling vent systems too shallow for the ship - BRR!🥶

Great end to the day at Submarine Networks EMEA with @mikeaclare.bsky.social of @noc.ac.uk and the International Cable Protection Committee (ICPC) and John Wrottesley of the ICPC and European Subsea Cable Association discussing unintentional impacts of human activity on marine infrastructure.

Excellent presentation at Submarine Networks conference by @isobelyeo.bsky.social of @noc.ac.uk on hazards for subsea cables affecting small islands worldwide - it’s complicated!
