100 metres of sediment core!

We’ve passed a huge milestone – we’ve now retrieved more than 100 metres of sediment core, so we are over halfway towards our target of 200 metres. Reaching this point is testimony to the skill and hard work of our drillers, who have managed some long runs pulling up cores of up to 3.1 m in length, and are delivering excellent recovery.

The core that took us past 100 m was pulled during the night shift, a boost for the team who work their 12 hours while the drill rig is mostly in the shade, and deal with generally colder conditions.
