Scientists investigated hydrothermal venting, from seeps that form underwater lakes of carbon dioxide, to bubbly venting at temperatures up to and exceeding 200ºC.

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!

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

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

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.
