Advances in geomagnetism

Equatorial Electrojet model developed by IIG
The equatorial electrojet (EEJ) is an intense current jet flowing in the upper atmosphere around 100 km.  This is a unique phenomenon that occurs at only a few kilometers in height (e.g., 105 – 110 km) and with a horizontal (North-South) width of a few hundred kilometers (e.g., ~600 km)... more

Weakened control of crustal magnetic fields on the Martian ionosphere
Mars is a planet which does not possess a global magnetic field. But it has weak local crustal magnetic fields in its southern hemisphere. Using nearly 8 years of MAVEN (Mars Atmosphere and Volatile EvolutioN) satellite in situ data, IIG scientists  investigated how the crustal magnetic fields... more

IS THERE A CONTINENT HIDDEN BELOW THE ARABIAN SEA?
Zealandia has caught the imagination of geoscientific world and reams of paper and netspace has been dedicated to announcing arrival of this new ‘continent’ on the block. Geoscientists have been working hard and long to identify the signatures that could mark a sunken landmass as a continent. They... more

THE NEW MEGHALAYAN AGE: (WHAT IT MEANS AND WHY IS IT NECESSARY?)
THE NEW MEGHALAYAN AGE:  WHAT IT MEANS AND WHY IS IT NECESSARY? The human race has divided time into different units since it culturally stumbled upon the abstract concept of time. We have broken time into variable slices like millennia, century, decade, hour, minute, second and so on. The... more

FACE OFF WITH THE SUN
FACE OFF WITH THE SUN The civilizations the world over have many myths and legends depicting powerful and divine individuals making a go at the sun. The end is more often than not quite discouraging. They always burn out near the sun. But, these folklores are symptomatic of humanity’s... more

BREAKING UP OF ICEBERGS AT ANTARCTICA: WHAT DOES IT MEAN FOR INDIA?
India is far away from Antarctica and the proceedings that take place over there should not be of concern to it. This is the feeling of most of us sane Indians. However, the natural system that the Earth is operating and dealing with leaves no room for such complacency. The Earth is an integrated... more

MESOSPHERE AND LOWER THERMOSPHERE (MLT): DYNAMICS AND COUPLING
Anybody who travels frequently will know that weather can change dramatically from one place to another. If this travel is done vertically, into the sky, then this change is all the more spectacular. It changes from a realm of dense molecular setting to an almost empty space. The change in... more
