The Life Science Association organized a
guest lecture on Demise of Arctic Sea Ice by Dr Vishnu Nandan, University of
Calgary, Canada. Dr Vishnu had done his research in the area of remote sensing
in measuring Arctic sea ice. He was the lead author of a research article which
was published in Geophysical Letters, October 2017 issue, which emphasised the
role of salt in sea ice which interfered with the measurement of polar sea ice
depths by satellites. He was also featured in the February issue of Frontline
magazine.During the session, he talked in detail about the techniques involved
in measuring sea ice thickness and also elaborated on the effects of dwindling
sea ice on the Arctic ecosystem. 
Dr
Nandan also gave another lecture on the topic “Potential Research and Career
Opportunities in the area of Climate Change Studies and Cryogeography to the
MSc students of Biotechnology, Botany and Zoology. The students were very
enthusiastic hearing the lecture and asked a multitude of
doubts after both the sessions to which Dr Nandan replied patiently and in
detail. The session was attended by students of BSc and MSc Life Sciences and
also few faculty from Life Sciences, Chemistry and Computer Science.
