A great trip is done, samples off to be shipped. Time to head south.

We’re headed back to port after a successful field season. Dodging snowstorms along the north coast of Spitsbergen

Out supporting the @protosignslab.bsky.social search for Neoprotorozoic fossils around Nordaustlandlet. Truly a lunar landscape.

Moving from Quaternary glacial evidence to much older glacial sediment from the time of snowball Earth, as well as volcanic material that floated to Svalbard during the Holocene.

One more day of chasing glacial clues of past climate in Lomfjorden before heading even further north.

Today was a day for tracking past sea level change. We found lots of raised beaches, shells, and a few whale bones.

A bit of Quaternary field work today sampling potential early Holocene moraines, with a nice meltwater channel carved into bedrock.

Great first day in the field mix of 800 million year old stromatolites and 10,000 year old glacial geology. @protosignslab.bsky.social

Finally on site for our field work, two weeks of Neoproterozoic fossils and Quaternary geology. @protosignslab.bsky.social @ucdearth.bsky.social

Brief stop on the way north in Ny-Alesund, the launching point for Amundsen’s zeppelin trip to the pole, and home to a number of Arctic research stations today. @ucdearth.bsky.social @protosignslab.bsky.social

Great walk to catch up on the local geology around Longyearbyen before we head north.

great day for a shake-down hike to make sure all the field gear is working.

In Longyearbyen to brush up on safety training before heading out to the field.

The early stages of a big trip. Headed up to Svalbard to support the @protosignslab.bsky.social expedition to NE Svalbard.

Such a good trip to be out and talking about the many aspects of mountain landscapes.

Wonderful day out in the Wicklow Hills with Sam Kelley @arctic-glacial.bsky.social providing a CPD for Mountain Leaders on behalf of @mountaineeringirl.bsky.social focusing on cultural and geological heritage. Thanks to MI and especially Helen Lawless for organising!

Great day out in the Dublin Mtns looking at evidence of the past ice sheets in Ireland with our 4th year class. We were very lucky to have caught the first dry day in quite a while; tors always look better in the sunshine.

Looking forward to the @quaternaryirl.bsky.social autumn symposium tomorrow, with keynote talks from Gregor Rink (Galway) and Andrew Cooper (Ulster) about how Ireland's coastline has changed. Many thanks to the Geology Survey of Ireland for hosting us.

Not a place I expected to publish, but great to see the summary of our geology-archaeology collaboration is so popular. Open Access summary paper linked below. Thanks to the IRC, now @researchireland.ie, for supporting this work.

A busy return to Ireland, but the geology team of Clara and I had a great field season mapping palaeo-lake features in Glen Dee, such as this lake shoreline behind Corrour Bothy.

Another great day out for the Quaternary geology class earlier this week with UCD Earth Sciences, looking at evidence of the last glaciation in the Dublin Mtns. Having a bit of sun was rather nice for a change, though was missed.

The upper Cameron valley in the Arrowsmith Range of the Southern Alps of New Zealand. Photograph features moraines constructed by the Cameron Glacier throughout the Holocene (vegetated ridges are those deposited during the early Holocene, and unvegetated ridges during the late Holocene), as well as incised meltwater channels, glacial outwash, alluvial fans, active scree slopes, etc.

Just back from the ~QRA2025 discussion meeting. Chilly, but really fun to see all the new Quaternary research. @ucdscience.bsky.social was well represented with a great talk by postgrad student Clara Crowell and the best student poster of the conference by Dakota Youngeagle.
