Marine volcanologist. All opinions my own. She/her.
The best thing about this job is that you get to keep learning. Absolutely incredible day looking at landslide and lahar deposits off Etna with amazing INGV scientists and @mikeaclare.bsky.social (who always teaches me things I don’t know about sediments).

Really enjoying the “surveying oceanic volcanism & volcanic island geohazards” session at @iavcei.bsky.social 2025. Great talks and lots of fascinating work on volcanic tsunamis. Looking forward to the second half this afternoon.

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.

Jeremy Phillips @bristolvolcanology.bsky.social with a fascinating presentation on how important erosion is when modelling lahar related hazards @iavcei.bsky.social So much work still to do to understand the behaviours of lahars on and offshore.

Great talk by @sofiadellasala.bsky.social looking at hydrothermal records at Santorini in the @iavceisubmarine.bsky.social session. Convincing evidence of vigorous hydrothermal activity in the past preceding eruptions and a great demonstration of why we should look at hydrothermal records.

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.

Having a lovely time at SubOptic 2025 in Lisbon this week. Really enjoyed today’s masterclass on fibre sensing - some great reasons to be hopeful for the future of deep ocean measurements.

Recovering our final OBEM! We’ve deployed and recovered 67 instruments on this expedition and, while you never put anything you’re not willing to lose in the sea, it’s very nice to bring everything home. Special thanks to the crew for their support with operations. @ukri.org @noc.ac.uk

Science is a team sport and we’re not the only people working around Santorini. Today we collected and redeployed two seismometers to assist our colleagues @geomarkiel.bsky.social better monitor recent seismic activity. This is them before they went back into the water. @noc.ac.uk @ukri.org

Busy few days! Now we’re sampling the gasses, fluids and rocks of the Kolumbo volcano hydrothermal system to understand how these hydrothermal sites are outgassing the magmatic system. It’s bubbly! @noc.ac.uk @ukri.org
March 15, 2025 at 8:45 AM
The @ukri.org RRS Discovery looking spectacular against the inside of the Santorini caldera. Incredible day sampling vents at a new site to understand how fluids circulate through a volcano for the @noc.ac.uk led HYDROMOX project.

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
March 8, 2025 at 12:55 PM
It’s a beautiful day for sampling the fluids that circulate through a volcano with the @noc.ac.uk ROV Isis. @ukri.org
March 7, 2025 at 7:50 AM
ROV is in the water and deploying seismometers to measure fluid flow and earthquakes for the @ukri.org @noc.ac.uk HYDROMOX project. Worked with this ROV on my first expedition in 2008. Still find driving around on the seafloor thrilling.
March 6, 2025 at 3:18 PM
Great 24-hours deploying the geophysical equipment that will collect the seismic and electromagnetic data inside and outside the Santorini caldera. This information will help us to map hydrothermal fluid flow and earthquakes for the @noc.ac.uk @ukri.org funded HYDROMOX project. Photo: Dan Bourne

Tomorrow we head to Santorini on RRS Discovery to study volcanic hazards for the @ukri.org @noc.ac.uk HYDROMOX project. So grateful for support from a brilliant science team, officers, crew and our logistics teams and thrilled this expedition, 5+ years in the making, is happening.
March 2, 2025 at 5:50 PM
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.
February 28, 2025 at 3:47 PM
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.
February 18, 2025 at 5:44 PM
Really great two days hosting the European Subsea Cable Association Cable Awareness Workshop at @noc.ac.uk. I think everybody learned a lot and I got to touch some of the most broken bits of cable I’ve ever seen. Props to @mikeaclare.bsky.social for doing all the work and giving me half the credit.
January 30, 2025 at 9:03 PM
Two cracking talks from @noc.ac.uk colleagues @mikeaclare.bsky.social and Jacob Nash on the last day of a great #VMSG_MDSG25 conference. Great examples of why understanding volcano-ocean interactions are essential and how the ocean record of volcanic hazards can help us plan for the future.

Sad that fieldwork in Tonga had to end but excited to work on the samples and data. One part of the study examines preservation of 2022 tsunami deposits. As humbling pictures of a resort before/after the tsunami and now show, there’s been change. @mikeaclare.bsky.social @volcanocronin.bsky.social

It matters who you dig tsunami deposit trenches with in the jungle and Dr Mike Clare has lived up to his self assigned “human mole” moniker today. This trench has deposits from 2022 and something earlier.

Sections of swimming pool and destroyed containers highlighting the exceptional strength of the tsunami flow reflection on steeper terrain.

Fascinating and sobering day looking at some of the damage and deposits from the 2022 Hunga volcano eruption triggered tsunamis in Tonga two years on, with colleagues from University of Auckland and National Oceanography Centre.
