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
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
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 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

Many Schools and colleges frequently visit IIG’s magnetic observatories that has spread across the nation. IIG runs total twelve magnetic observatories spanning east-west and north-south region of our country. Understanding working of magnetic observatory, measuring magnetic field of the Earth,... more
Many Schools and colleges frequently visit our regional centres/labs spread across the nation. IIG has three regional centres namely KSKGRL, Prayagraj, EGRL, Tirunelveli and NEGRL, Shillong. The students/teachers get opportunity to see different experimental set up, state of arts labs, instruments... more
The school/college visitors were acquainted with the basics of geomagnetism, GPS and other related activities carried out at IIG. Posters, models, lab visits and talks were arranged to enlighten them on the advances made at IIG in the field of geomagnetism and allied areas. All the activities were... more
