Last Saturday we had our first field trip of the year! Dr. Chris Jass and Katherine Bramble led us around the collections at the Royal Alberta Museum, showing us the parts of the collection that the public generally doesn't get to see. Along the way we learned about Ice Age mammals, becoming a palaeontologist, and the role of the gravel industry to palaeontology.

I have made claims about a lagoon of unfrozen water along the east coast of england and scotland during the last ice age. The evidence for this and other absurd claims is laid out here.

Quaternary (Geological periods 🌍)
The Quaternary is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy, as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary ...

🔦 Feldforschung in Alaska: Der #Geologe Paul Wilcox entdeckte dort in einer schwer zugänglichen Höhle rund 20.000 Jahre alte Ablagerungen. Eine Analyse dieser Proben erlaubte Rückschlüsse über das Ende der letzten #Eiszeit und darüber, wie das Abschmelzen der riesigen Gletscher damals vor sich ging.

An #IceAge is a period of long-term reduction in Earth's temperature, resulting in the expansion of continental ice sheets and alpine glaciers. These periods are characterized by significant changes in climate, sea levels, and ecosystems.
Earth is currently in the ice age called #Quaternary #Glaciation.

Wonderful to see 11 ARC Discovery Projects awarded to Quaternary projects in Australia! This must be a record for recent years/rounds.
Sleuthing thanks to Prof Simon Haberle at the ANU via the aqualist.

The first paper for our paper club is this recent one from McKay et al., presenting a thorough investigation of the (supposed?) 4.2 ka event. I'd read it when it was published, but just went through again in more detail, and what a good paper. Robust stats (of course, from this group), and they do a really nice job of building the case. I hope the group enjoys it!

#Curtin uni is advertising an ongoing lectureship (level B, teaching and research) in Earth and Planetary Sciences. Pretty broad criteria, would suit someone doing #Quaternary sciene as well as more traditional minerals stuff.

Australasian quaternarists will be happy to see that the call for abstracts for #AQUA2024 has been opened! AQUA is also offering student travel awards - all the details are slowly emerging on both the website and the mailing list.

FYI Australasian quaternarists, there is AQUA news!
1. Membership is due (we run on the calendar year) - join or renew here: https://aqua.org.au/membership/become-an-aqua-member/
2. The AGM is coming up! If you have some ideas about how AQUA should be run, consider joining the executive - it's a friendly bunch. To stay abrest, join the mailing list: https://mailman.anu.edu.au/mailman/listinfo/aqualist
