Final lab of the semester for my Quaternary Geology class was a sporting one: fording the river and digging out a nice exposure of 14,000-year-old varves from proglacial Lake Vermont. #geology #Quaternary #Vermont #spring #outside

Dear #EGU25 attendees, please consider going along to our session, "CL1.2.12 Understanding carbon cycle – climate interactions during the Quaternary through the study of oceanic circulation, vegetation, and wildfire", which is taking place on Friday.

Students in my Quaternary Geology course came at this exposure from the bottom up, and the top down -- a curious sequence of basal till overlain by silty lake sediments deformed by a later glacial readvance. #geology #earthscience #vermont #Quaternary #outside
After gaining experience at a fairly straightforward site, students in my Quaternary Geology course have moved on to more complicated exposures. This one here reveals basal till beneath proximal subaqueous outwash that was deformed by a readvance. Great stuff! #vermont #geology #EarthScience #glacial #Quaternary #outside

Students in my #quaternary #geology course retrieved a sediment core from a local lake and analyzed it in the lab. They've produced an impressive dataset to support an environmental reconstruction spanning the past few centuries. Nice to have such solid #ice this #winter! #vermont #fieldwork #EnvironmentalScience #EarthSciences

Homo juluensis: Scientists discovered a new species of archaic human
A team of paleoanthropologists has introduced Homo juluensis, a newly identified hominin species. This species, whose name translates to “big head,” thrived in eastern Asia between 300,000 and 50,000 years ago, marking a significant addition to the Late Quaternary human lineage...

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.
@DrEvanGowan I had a similar thought when looking at the ages and the materials that were dated. Nonetheless, it's fun that there can still be such debate over a thousand-km difference in the position of the ice margin! I'll be interested to see the new data from Manitoba. #glaciers #geology #quaternary
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!
Australian quaternarists and micropalaeontologists - applications for the Leanne Armand Travel Award are now open. Details on the #AQUA website: https://aqua.org.au/sample-page/the-leanne-armand-travel-award/
#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.
The #SFUEarthScience #Quaternary #geology class had a great field trip this past weekend exploring the Channeled Scablands in #Washington State with mostly cooperative weather.
Brent Ward's Quaternary Geology class is taking the #SFUEarthSciences big red bus to the Channeled Scablands this weekend - a bucket list item for many #quaternary geologists.
