Science Report: Antartica

Weekend Variety Wireless 17/02/2018

Craig Stevens from NIWA describes sampling the sea under 300m of Antarctic ice-shelf, that were larger than Spain. 

The sea underneath had only been sampled once before... 40 years ago.

It's Mr Stevens 12th or 13th time to Antartica... he's lost count. 

To drill the ice, his team uses hot water drilling, and sometimes it instantly starts ice-ing up again. 

Mr Stevens says they were able to detect meltwater from different parts of the ice shelf, and he does believe there is an ecosystem under there.

He explains if these shelves collapse, the ice flows into ocean faster, meaning we get a greater amount of sea level rise.
