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.
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.
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.
