Just completed a fieldtrip for a new Marsden project on glaciation in the #Clutha. Found some spectacular boulders on the edge of a proglacial fan near #Cromwell. Dating the boulders using #CRN #geomorphology #geochronology #geoscience #geology #geography #Aotearoa #NewZealand #cosmogenic

Mystery photo for you to work out what it is? Is this a debris flow? Or maybe a rock glacier? Or perhaps a talus deposit? Or something else? Give it a guess. #Geomorphology, #landslide #newzealand #geoscience #geography #geology

#NewZealand #geomorphology post of the day. This is the Kawerau Gorge near Queenstown. Glaciated in the last ice age and famous for strath terraces (cut into bedrock) - visible on the right bank of the Kawerau #river. #geoscience #geology #geography #Aotearoa

It has been a privilege speaking at the Voices of K'gari conference. This meeting brings together Butchulla, scientists, and wider community to advance knowledge and understanding of K'gari. #Butchulla #Kgari #Australia #culuralheritage #biodiversity #geomorphology #sand #Queensland #CIEHF

Early bird registration has closed for the IGC conference in February 2026. If you have submitted an abstract but not yet registered please do so asap. You can also still submit a poster and/or just attend. See you in Otautahi - #Christchurch ! #geoscience #geomorphology www.confer.co.nz/icg2026/

Just came through an extreme weather event in #NewZealand. 145 km winds in the low country and over 200 kph in the Southern Alps. #Christchurch where I live we had an astonishing near miss with high winds hitting north and south. #wind #weather #lucky #storm www.thepress.co.nz/nz-news/3608...

We are closing in on the biennial conference on K'gari. The 'Voices of K'gari' conference on November 10th and 11th. It will be a chance to share new knowledge and ideas on K'gari. #Butchulla #Kgari #culturalheritage #climatechange #geomorphology #biodiversity www.usc.edu.au/study/life-a...

If you are attending the 11th IGC Conference in February 2026. Come along on the mid-conference Glacial Geomorphology fieldtrip to the Waimakariri to see landscapes like this... #geomorphology #NewZealand #Christchurch #geoscience #geology #geography #Aotearoa

I have been offline for a while as I have been doing fieldwork in the Channel Country of SW Queensland. #geomorphology #river #Australia #channelcountry

The Ashburton Lakes (Hakatere) region is a high altitude basin between the Rangitata and Rakaia Rivers, Canterbury, New Zealand. It was heavily glaciated as the kame terraces (deposits of a river running along the flank of a #glacier) show. #geomorphology #photo #geology #geography #Aotearoa

Gravel cliffs at Rakaia Gorge, Canterbury. This cliff displays two #glacial #outwash gravels. The lower, orange gravel is from MIS 6 (c. 150,000 years ago), while the upper grey gravel is from the last glaciation c. 26,000 yrs ago. #geomorphology #photo #geography #geology #NewZealand #Aotearoa

wave-cut terraces on the flank of Banks Peninsula at Sumner. The very low terrace is likely mid-Holocene while the prominent higher terrace may be last interglacial. #geomorphology #coastal #Aotearoa #NewZealand #photo #geology #geography

The modern shore platform at Kaikoura. On this tectonically active coastline there are are series of raised marine terraces. The coast is periodically uplifted - the last time by the M w 7.8 earthquake in 2016. #geomorphology #geology #coasts #photo #newzealand #aotearoa #tectonics

For those of us interested in K'gari, the annual K'gari Conference is well worth attending. It is on from 10th-11th November at the USC Fraser Coast campus. The conference is supported by the BAC, BNTAC, FIDO and FINIA. Abstracts by 1 Sept. See www.usc.edu.au/kgari-confer....

Rapid incision of rivers through bedrock creates strath (rock) terraces. This example is from the Kawerau Gorge in Otago, New Zealand. #NewZealand #geology #geomorphology #rivers #photo #Aotearoa

Happy to report that I have completed my term as Head of School of Earth and Environment at the University of Canterbury. I revert to being a regular Professor in the School. #UCNZ #research #gelogy #earthscience #geography

A final reminder that we have a permanent position at Lecturer/Senior Lecturer (Assistant/Assoc Prof) level in Active #Tectonics and #Geomorphology at the University of Canterbury, #NZ. Closes on 28th June. Come join us. #Geology #hazards jobs.canterbury.ac.nz/jobdetails/a...

Tafoni (cavernous weathering) in rhyolite on Ahu Ahu (Great Mercury Island), New Zealand. The formation of tafoni is cryptic, but this boulder is about 150m from the sea and it may be due to salt weathering. #geomorphology #erosion #geology #photo #Aotearoa #geoscience #NewZealand

Three permanent positions in the School of Earth and Environment at the University of Canterbury closing soon. 2 days to 2 positions in Engineering geology. 7 days to our position in Active Tectonics and Geomorphology. Come join us. jobs.canterbury.ac.nz/jobdetails/a...

My last call for abstracts for the International Conference on Geomorphology in Christchurch www.confer.co.nz/icg2026/ - last day for abstracts June 13th Oh what lovely vineyards, sorry Central Otago landscape. #photo #geomorphology #NewZealand #geology #geography

Not to mention the importance of these students for the local economies in the towns and cities the universities are located.

This footage of a rock and ice #landslide from the Birch Glacier in Switzerland is spectacular. There seems to be a lake forming behind the landslide fill in the valley floor, so the sequence of events may not be over. #Geomorphology is exciting. #geology #geography ⚒️ #geoscience

Update on the February 2026 International Conference on Geomorphology in New Zealand. We have extended the abstract deadline by 2 weeks until 13th June 2025. We have great plenary speakers, fieldtrips and young geomorphologist programme. #geomorphology #geoscience www.confer.co.nz/icg2026/

To contrast with the New Zealand (or at least mountainous) #geomorphology that I usually post, here is a spectacular geomorphic scene from far west Queensland. #photo #bigsky #peneplain ⚒️ #geoscience #geography #Australia #biodiversity #gibber #geology

One week to go for abstracts for the International Conference on Geomorphology in #Christchurch, New Zealand. www.confer.co.nz/2026/icg2026/ Come see the beautiful rias of Marlborough which are a consequence of local #tectonics. #geomorphology #NewZealand #coasts #geology #geoscience #geography

Yesterday I showed a photo of an eroded #dune at the back of a beach in #Christchurch. The foredunes are eroded and build up again very quickly, as the plastic wrapper eroding from the dune shows. They act as key protection for the land behind. #coastal #erosion #aotearoa #geology #geomorphology

View of the #beach at Spencerville north of #Christchurch today. The beach is strong dissipative reflecting erosion during recent storms. It will recover, if and when we get a break in the storm sequence. #geomorphology #coastal #Aotearoa #NewZealand #geoscience

This is a fascinating post from the #Independent. One of the primary drivers of #Brexit was for the #UK to regain control of its borders and to limit #immigration. The reverse has happened, mostly under the #Conservatives. Narrative versus reality?
