WACSWAIN: Time and ice

My last blog about the WACSWAIN project was in February 2020. We had just started the chemical analysis of our 651-metre-long ice core from Skytrain Ice Rise (Antarctica). The theme of this article is time – the first aspect being that a lot of time has since passed. Soon after I wrote last, our labwork was completely shut down by the pandemic, some of the team went back to their families in other countries, and we all learnt what Zoom meetings were.

WACSWAIN: the hard slog of analysis

The last time I blogged about WACSWAIN was in January 2019, when we were in the euphoria of having drilled to the bedrock at Skytrain Ice Rise, and retrieved 651 metres of ice. So what have we been doing since then?

WACSWAIN Drill Log: ice core complete!

The aim of our fieldwork in Antarctica is to retrieve an ice core reaching through the entire depth of the ice cap on Skytrain Ice Rise, to obtain ice extending at least 130,000 years back in time. Last night, on Tuesday 7 January, we succeeded. The feeling of elation is all around me, with all six members of the party relieved and excited.

WACSWAIN Drill Log: Christmas in Antarctica

We’ve now been at Skytrain Ice Rise in Antarctica for about 6 weeks. In previous blogs, I have written about the life in camp and the drilling. Now, just after Christmas, it’s time to take stock of what we have achieved, and what we are aiming to do.

WACSWAIN Drill Log: ice core drilling begins

In order to achieve our goal of retrieving ice that is 130,000 years old, we need to drill a core to the bottom of the ice cap we’re camping on, through about 620 m of ice. All the work so far has been preparation for drilling, so what does the drilling actually involve?
