In our July Newsletter we hear from the #Exp395 Science Party (@mcnamadd.bsky.social, Sevi Modestou, Tom Dunkley Jones, Nicky White and Paul Pearson) about their post-cruise research on the Reykjanes Ridge, Iceland plume and paleoclimate of the North Atlantic.

Brilliant! 😆

Everywhere you look in Troodos - celadonite, a common ocean crust alteration mineral. Such an amazing trip to see the Troodos Ophiolite in Cyprus.

Super proud of all my second years on their mapping training field trip! They all worked really hard and I think they learned a lot and hopefully enjoyed the trip! @liverpooluni.bsky.social

UK researchers on the Joides Resolution.

Team UK on IODP Expedition 395! Good times. 😍

Hi folks - anyone got any good sources or know where we could source or buy samples of zeolites for experimental fluid rock tests?

So cool!

Sample of basalt breccia from the Mid Atlantic Ridge.

Cataloging samples of oceanic crust from the Mid-Atlantic Ridge we drilled a couple years ago. Plenty of exciting data coming out soon - just gotta keep up the writing! 😅😓

Looking at Iceland’s geologically shaped surface from the air is amazing. 😍

View of Etna looking N (ish)

Feeling spoiled this holiday to have hotels with stunning views of Vesuvius and of Etna!

NOT gold structures - fold structures!! I wish gold structures… 😅

Synform in metaseds

Antiform in metaseds

Found some amazing gold structures in the Silurian metasediments while on a trip back home to County Down. These are at Kearney shore on the Ards Peninsula.

I wondered the same thing but we didn’t have time to go down and look
at them directly. They do look that way though!

Columnar jointing with multiple orientations in lava flows in the Nevados de Chilean area of Chile! 🤩

Geothermal fumaroles

Sulfur alteration and mineralization

Hiking, geothermal, and beautiful surface alteration minerals at Nevados De Chilean - amazing field trip with our Chilean hosts and experts Profs Gloria Arancibia and Diego Morata. 😍

Me staring at a mineral sample display

Just staring longingly at the mineral samples on display at the NY Museum of Natural History - this pink stunner is elbaite tourmaline.

One of my paper figures showing omphacite grains with chemical zoning supporting diffusion creep processes operating during deformation of these rocks

It’s finally out and published - John Wheeler, Mark Pearce, Dave Prior and I publish some of my old PhD work showing evidence for diffusion creep in omphacite from Italian eclogites . 🥳

Also this work has just been published in Journal of Structural Geology - you can read the pre proof here!

Me at my poster

Poster details

Did the last AGU poster yesterday - was an exciting one as I was presenting some work from my PhD (about 14 years ago) that we unearthed and decided to polish up! Looking at diffusion creep in eclogite formation! Thanks again to all who stopped by for chats!

Poster is online for AGU!

Great time presenting Katharina’s work on wireline in the Bjorn Drift sediments yesterday - fun project to work on!

Poster at AGU

Alteration poster here!

Poster time and location info

Ok - I’m here and ready to start doing AGU 2023 😅

First up today a poster from team alteration from IODP EXP395 showing off some of our ship board data from core logging across the mid Atlantic Ridge. Shout out to Gabriel Pasquet for leading this poster! 💪🏻

Come say hi!

Wonderful to be at the 10th UK Geothermal Symposium at the Geological Society in London this week. Great first day yesterday and still two jam packed days to go - it’s our biggest conference yet for geothermal in the UK - hopefully a sign of growth for the industry here!

I didn’t this time but have had one before! The cheese is… well it’s a choice! 😂

Me with the Temple University mascot the owl.

Skyscrapers in Philadelphia

Me at the Rocky statue in Philadelphia

Had such a great time in Philadelphia visiting Temple University and talking about geomechanics and geothermal. Thank you for hosting me and thanks Philadelphia for the wonderful stay! 🤩

It’s an amazing place - visiting this as a kid definitely was part of why I’m a geologist today!

Please read and consider signing this open letter to UKRI regarding their initial and future responses to Michelle Donelan: docs.google.com/document/d/e...

As a geologist I immediately beelined to this painting ‘The Eruption of Vesuvius’ by Pierre-Jacques Volaire at the Art Institute of Chicago. I kept thinking the silhouetted people were early volcanologists. 😝
