We report, in this work, the changes in the thermal structure of the mesosphere-lower thermosphere (MLT) region over an Indian Antarctic station Bharati (69.4 ◦ S, 76.2 ◦ E, CGM coordinates 75 ◦ S, 97 ◦ E) brought about ...
Simultaneous observations of the atmospheric electric potential gradient (PG) at Bharati and Maitri stations were studied from 2014 to 2016. A new regional diurnal pattern of fair-weather PG for the coastal Antarctic region, ...
The ionic and isotopic ratios of some lakes in the Larsemann Hills in East Antarctica are determined to assess the lakes’ chemical and isotopic evolution. The lakes occupied the natural depressions carved by glacial abrasions ...

The study aims to find out the ionic and isotopic compositions of some lakes in the Schirmacher Oasis in east Antarctica. The water samples were collected from 12 lakes near the Indian Antarctic station, Maitri. The chemistry ...
The present study has focused on the intense production of cosmic noise absorption (CNA)
at Maitri, Antarctica (L = 5; CGM −62∘S, 55∘E) during the early recovery phase of the largest storm of
the current solar cycle ...
In this paper, we review the progress in Geomagnetism and allied areas based on the past thirty five Indian Antarctic
expeditions and summarize the scientific results obtained in the last decade. Various dynamic processes ...
In this paper we study the horizontal
component of the Earth’s magnetic field and the
effect of solar features on geospheric conditions is
carried out and carried out at the Indian
Antarctic Station “MAITRI”(geom. Lat. ...
We have examined three well-defined
events of sawtooth oscillations in solar wind and
magnetic field at high-latitude. For this study we
have taken data of H component collected from
digital fluxgate magnetometer at ...
The scope of this paper is to explore the mechanisms operating over Maitri (70.76°S, 11.74°E,
117m above mean sea level), a coastal Antarctic station, that produce an anomalous fair-weather diurnal
pattern of the atmospheric ...
A comprehensive measurement of radioactivity concentrations of the primordial radionuclides 238U,
232Th and 40K and their decay products in the soil samples collected from the sites of Indian research
stations, Bharati ...

The paper discusses on the variations of the atmospheric vertical electric field measured at sub-auroral
station Maitri (70◦75
S, 11◦75
E), and polar station Vostok (78.5◦S, 107◦E) during the geomagnetic
disturbances ...
Schumann resonances (SRs) are the AC components
of the global electric circuit and are excited by the
lightning activity within the Earth–ionosphere waveguide.
An induction magnetometer, which was operated
from the ...
A significant proportion (10%) of the natural background radiation is of cosmic origin. Cosmic ray consists of gamma, protons, electrons, pions, muons, neutrons and low Z nuclei. Due to the geomagnetic effect, cosmic ...
Cosmic noise absorption (CNA) measurred by imaging riometer, is an excellent tool to passively study the high latitude D-region ionospheric conditions and dynamics. An imaging riometer has been installed at Indian Antarctic ...

Global positioning system (GPS) campaigns were conducted during the 2003 and 2004 austral summer seasons to obtain insight into the velocity and strain-rate distribution on Schirmacher Glacier, central Dronning Maud Land, ...
The Earth's magnetic field is due to huge electric current circulating in the core of the Earth. Geomagnetic field is mostly dipolar in nature although multi poles also have some contribution. However, the main complication ...
Monitoring of ice sheet velocity is one of the key issues to glacier dynamics understanding. Although the surface displacements of glaciers can be monitored Global Positioning System (GPS), this process is difficult in ...
A fluxgate digital magnetometer is used to study the variation of magnitude of H component during geomagnetic storm events of April, July and November 2004 at southern subauroral localized region at “MAITRI” (geom. lat. ...
