The Antarctic Intermediate Depth Drill (AIDD) has three coring systems that we can use: a hydraulic piston corer, a push corer, and a rotary corer. Piston and push cores are collected in plastic PVC core liners, whereas the rotary corer collects the core directly in the core barrel, which is then extruded onto core liner that has been split in half. The other half of the liner is placed on top and then the core is wrapped to hold it in place during shipping. 

We will split the cores during our core description workshop early next year.

Scientists Drilled Into Antarctic Ice Until They Met Bedrock, Then Got A 228-Meter Sample Of Sediment

Scientists have just got their hands on a 228-metre (748-foot) core sample from the muddy bedrock beneath West Antarctica’s chunky ice sheets. Inside the record-breaking sample, they discovered fossils of marine organisms that date from a time when this area was an open, ice-free ocean.
