Third 'IMOS in MOcean' video – What do changes in the Southern Ocean mean for the Antarctic ice sheet?

The 3rd video in the 'IMOS in MOcean' series examines evidence that a warming Southern Ocean is contributing to Antarctic ice sheet melting.

Meet the people behind the variety of marine observations that make up the IMOS data collection. Today, IMOS introduces the third in our series of videos called 'IMOS in MOcean'.

The East Antarctic ice sheet and shelves, once thought to be stable, are showing signs of thinning (melting).

Using data from IMOS funded moorings off the Totten and Mertz glaciers, Dr Steve Rintoul presents evidence that warm water beneath the ice shelf is causing this ice loss.

Dr Rintoul explains that obtaining good time-series data on ocean variables near these East Antarctic glaciers will improve our understanding of processes and time frames of glacial melting and the potential for sea-level rise.

Other videos currently in various stages of production are:

  • IMOS: an overview – takes a step back and explains what IMOS is about and why time-series observations are so important
  • OceanCurrent – the people behind the valuable up-to-date ocean maps
  • Shark movements – how tracking sharks has revealed startling new insights into their behaviour
  • Ocean Data portal – a guide to accessing IMOS data collections as easy as 1,2,3
  • Southern Ocean and Climate – shows how processes in the Southern Ocean play a key role in global climate

A number of other videos are being planned so that the collection of videos will eventually represent the diversity of data collections and collectors, partners and end-users.

Keep an eye out for future episodes and do let us know if you have an idea for a new video.
