By 9am all was set for drilling to start
This is how we drill the ice cores:
One of us measures the core, matches it with the previous section and cuts it to fit it into the 1 metre 'layflat' polythene bag that is already prepared and labelled. The core then goes into an ice core box, with all necessary details noted into the field notebook.
There are quite a few technical issues that can slow down the drilling process. The quality of the ice can change, and sometimes faults develop with the drill itself. Xinsheng has an amazing ability to remedy these pitfalls - I was impressed watching his resourcefulness as we progressed
So here on Annette Plateau, our first drilling was going well. There were several dust layers in the core at intervals, most likely suggesting summer layers where melting at the surface had concentrated wind blown dust into a distinct deposit.
Progress was good. Apart from a short wet layer at 29 metres, the ice was looking cold and bubbly - good quality glacier ice. We continued drilling until 11 pm by which time we had reached about 40 metres below the surface.
