Thank you. If there was ever a moment in time to learn from history. The Miep Gies episodes were great.

The next region in New Zealand I’ll look at is the Wellington region. Wellington is the New Zealand capital, and the greater Wellington region has a population of ~430K, third largest in the country behind Auckland and Christchurch. 1/ 🧪

Tall mountains and tiny flowers. Gorgeous little South Island edelweiss hiding between rocks. Another amazing day around Aoraki/Mt Cook National Park during the GNS Science GNSS/GPS field campaign

yeah, unfortunately they had destroyed one of the stations. But I quickly forgave them, far too cute.

I am very very jealous that this family on Prince Edward Island (Canada) had a small meteor hit their sidewalk and managed to catch it on their door cam in what is likely the first audio and visual recording of a meteor strike!

It’s a dark day for research in Aotearoa New Zealand and the ramifications for the country are huge. Minister Judith Collins has just announced our blue-skies funder will no longer fund humanities & social science research and that 50% of what is funded must have economic benefit.

Had an awesome last day of the 2024 #GSNZ conference, fieldtrip to learn about Dunedin’s Volcanic Geology which included a visit to Quarantine Island. Many thanks to Ayla, Marco and James

This morning has a nice write up by @jamiemorton.bsky.social of our recent work investigating how Taupō volcano responded to shaking from the 2016 Kaikōura earthquake: www.nzherald.co.nz/nz/surprise-...
Kaikōura 2016 earthquake linked to unrest at Taupō supervolcano - 500km away
It’s been a question on the minds of geoscientists - can big quakes trigger eruptions?

Well I guess, since I made an account, I might as well share couple of field photos from today.
