Antarctic ice loss altering earth’s gravity: Study

A new scientific study has found that a sudden and massive ice loss in a previously stable region of Antarctica is causing small changes in the gravitational field of the Earth.

This study was led by Dr Bert Wouters, a Marie Curie Fellow at the University of Bristol, England and was recently published in Science Journal.

Key highlights of Study

  • The changes were observed using the CryoSat-2 satellite, a mission of the European Space Agency (ESA) dedicated to remote-sensing of ice.
  • Researchers have found that the ice surface of some of the glaciers is currently going down by as much as 4 m each year.
  • They also have found out that Southern Antarctic Peninsula showed no signs of change up to 2009. But after 2009, multiple glaciers along a vast coastal expanse suddenly started to shed ice into the ocean.
  • These glaciers measure around 750 km in length and are shrinking nearly at a constant rate of 60 cubic km and adding about 55 trillion litres of water each year.
  • With level of shrinking, this region now has become the second largest contributor to sea level rise in Antarctica and causing small changes in the gravity field of the Earth.

John Forbes Nash, Jr. was born on June 13, 1928 in West Virginia State of United States.

Work: He was renowned for works in game theory (mathematical study of decision-making), differential geometry and partial differential equations.

His theories (especially Nash Equilibrium in game theory) are used in modern computing, economics, evolutionary biology, artificial intelligence, accounting, politics and military theory.

Awards: In 1994, he shared Nobel Memorial Prize in Economic Sciences with game theorists Reinhard Selten and John Harsanyi.

In 2015, he was awarded the Abel Prize along with Louis Nirenberg for his work on nonlinear partial differential equations.

Paranoid schizophrenia: In 1959, he got mentally ill and had undergone treatment of Paranoid schizophrenia. Later in 1970s he had recovered from mental illness.

A Beautiful Mind: His breakthroughs in maths and his struggles with schizophrenia were basis for biography A Beautiful Mind written by Sylvia Nasar’s.
