Drilling into the Antarctic ice by India begins
Dec 02, 2016

What is this project all about:

This is an Indo-Norwegian project to understand the response of Antarctic ice shelves to the global warming.

Where this project is carried out:

It has begun in the less-studied areas of East Antarctica, especially the Dronning Maud Land (DML), which is characterised by loosely-connected ice shelves along the 2000-km-long coast. 

Why East 

Ice shelves of East Antarctica are poorly understood when compared to the West Antarctica region.

Why this project:

Climatologists are increasingly worried about the large uncertainties in the future Antarctic contribution to the global sea-level rise since the Antarctic contribution to the climate changes has increased significantly during the past two decades.

Scientific activities that will be undertaken:

  • Under the project, mass-balance, dynamics, and climate of the Dronning Maud Land coast, East Antarctica (MADICE), geophysical field measurements, ice core drilling, ice-sheet modelling and satellite remote sensing-based studies will be conducted to understand the future Antarctic contribution to the global sea-level rise.
  • The researchers will try to better understand the current status and dynamics of ice shelves in Dronning Maud Land to decipher its response to the future climate change, said a communication.
  • Studies on the mass balance and long-term evolution of the Antarctic ice rises (grounded ice mass leading to an elevated part of the ice shelf) and assessment of its impact on the Antarctic ice-shelf stability and ice-sheet loss too will be carried out.
  • Attempts will also be made to reconstruct the recent changes in Antarctic climate using ice cores and its possible teleconnections to global climate.

Collaboration:

The scientific programme, jointly funded by the Ministry of Earth Sciences, India and the Research Council, Norway, has NCAOR and the Norwegian Polar Institute (NPI) as the partnering research institutions.
