I study marine diatoms in a span of time from the Cretaceous to the Pleistocene. My microscope “time machine” allows me to observe their response to the KPg extinction, West Antarctic Ice Sheet History, and to better understand the ocean.

Drilling a 200m sediment core from the bedrock beneath 500m of Antarctic ice is a complex process, so we've broken it down step-by-step in this explainer. From melting snow in our flubbers through to filling our core barrels, what we're attempting 700km from the nearest base is no mean feat!

I am beyond furious at the U. Nebraska administration and Regents for this decision. They are moving ahead with eliminating programs despite nearly 6 hours of public comments arguing they should not do so.

Every program was profitable, the math was badly done and wrong, and they were told this repeatedly in advance of the vote.
“The Daily Nebraskan found in the leaked spreadsheet that every program eliminated appeared to be profitable…every program that the chancellor proposed eliminating generated more money from tuition dollars than the department costs to run”

Another day =
another day hearing yet another brilliant Antarctic or other science colleague has lost their job.
Meanwhile, House passes a budget resolution that will add trillions to the deficit + death & poverty.
Don’t tell me it’s about fiscal responsibility. The cruelty is the point.

An uninvited guest - a Condition 2 storm - has prevented our drillers at Scott Base flying to camp, and grounded our science team in Christchurch. Weather delays are common in Antarctica, and are factored into our plans. Hoping to get on the move tomorrow! 📷 SB storm:Jane Chewings, C17:Ana Tovey
