Core on deck!

We have successfully retrieved sediment core from beneath 523 m of ice at Crary Ice Rise, rotary coring with our custom-designed Antarctic Intermediate Depth Drill.

Our first core measured in at 2.27 m, and by the end of the first 12-hour shift we had more than 10 m of core.

After the challenges of the first two seasons, we are thrilled to be underway with obtaining the elusive geological record that we’re seeking from deep beneath the ice.
