The Fourteenth Indian Expedition to Antarctica comprising 62 members which
included 25 wintering members, sailed on-board the Norwegian vessel 'MV Polar Bird' from
Goa on 17th December, 1994. The team comprising 30 scientists including an Observer
from the Department of Ocean Development was led by Dr. S. D. Sharma, a Physicist from
National Physical Laboratory, Delhi. The following scientific and logistic tasks were
accomplished by this team which returned back in March 1995.
2.1.1 Scientific Accomplishments
Atmospheric Sciences
A state-of-the-art Laser Heterodyne System was commissioned and successfully tested
for measuring vertical profile of ozone upto stratospheric heights.
An indigenously developed Millimetre Wave Radio-spectrometer was used to measure
the emission lines of atmospheric ozone on a continuous day and night basis over the
year.
Planetary Boundary Layer Studies were conducted to understand atmospheric turbidity
and dynamics of lower atmosphere.
For the first time in Antarctica, India carried out experiments on day time auroral
phenomenon using an indigenously fabricated dayglow photometer.
Biological Sciences
Studies on moss water lake communities through investigations on the occurrences of
Phylum Tardigrada which acts as a unique signature community in cold conditions, was
initiated.
A project to devise a long-term monitoring system on population dynamics of seals and
avian taxa using aerial census, was initiated.
Medical Sciences
As an ongoing experiment, studies on correlation of circadian rhythmicity and metabolic
status of personnel and monitoring of body parameters were carried out. These
experiments are aimed at enhancing the physical and mental capabilities of human
subjects under extreme weather conditions.
A new experiment to monitor the correlation between human body and geomagnetic
disturbances in Antarctica was undertaken.
Communication and Engineering
A hall mark in long distance communication was made with the commissioning of
electronic mail from Maitri through INMARSAT. This has enabled on-line data transfer to
and fro Antarctica.
Environmental Sciences
Environmental Impact Assessment Studies through the analysis of diverse samples
of land, air and water from Antarctica with the aim to generate baseline data required for
devising an environmental monitoring protocol, were taken up.
2.1.2 Logistic Tasks performed by the Fourteenth Expedition
The major time bound logistic tasks undertaken by the team were as follows:
Completion of garage-cum-workshop for vehicle maintenance.
Site location and foundation for balloon launching hut.
Augmentation of summer hut facilities.
Insulation and erection of liquid nitrogen hut.
Routine maintenance of Maitri infrastructure and shifting of cargo from shelf to Maitri
through land convoys.
