A major science expedition is setting sail to Antarctica this morning, in a bid to understand global warming.
The JOIDES Resolution will investigate how ice sheets and sea levels will react to climate change.
Its methods include drilling up to a kilometre into the seafloor, to look at greenhouse worlds that existed 20 million years ago.
The ship has just wrapped up its study of the Hikurangi Subduction Zone east of Gisborne, looking at quake conditions within the fault zone.
The ship will head back there in early March, after it has finished at Scott Base.
