Bengaluru, March 23: Indian Space Research Organisation has been achieving enormously this year. After launching 104 satellites on a single rocket in the space, ISRO will also be joining the Indian Scientific Expedition to Antarctica this year. The core study area of the 36th Indian Scientific Expedition to Antarctica will be climate change. Using the Ground Penetrating Radars (GPRs), sea ice will be verified and conditions of snow over sea and land ice.
The main objective of this expedition is to install stakes on ice for Differential Global Positioning System (DGPS) measurements around Bharati and Maitri to validate glacier surface velocity.
Four teams from ISRO will be attending the expedition; Ahmedabad with two members, one from National Remote Sensing Centre (NRSC) Hyderabad with four researchers, one from Indian Institute of Remote Sensing (IIRS) Dehradun with one scientist and one from Space Physics Laboratory(SPL) VSSC Thiruvananthapuram with three members.
The expedition will study the snow density, wetness and profile temperature using space and ground based observations. ISRO will also be measuring the concentrations of atmospheric constituents like CO2, CH4 using the ultra portable Greenhouse Gas Analyser/Licor CO2 analyser. The objective of this project also includes estimating the atmospheric visibility with the help of CCD camera.
All these experiments and observations are conducted to understand the complexities of climate change. Global warming poses a global threat and to take precautionary measures is urgent and crucial. Thus, Indian Scientific Expedition is vital at the moment as it will put light on areas of endangerment to human race.
