Solid Earth Research Group (SERG)
The main research goal of the Solid Earth Research Group is to comprehend the origin and evolution of the planet Earth and its various solid reservoirs such as the crust, mantle and the core. To achieve this the group focuses on deciphering the timescales and understanding the processes of geodynamic evolution of Archean cratons, Proterozoic mobile belts and Western Ghats of India. In addition, the research of the group aims at understanding the chemical evolution of the Earth’s mantle since the earliest differentiation events by studying mantle derived rocks at different tectonic setting, including active subduction zones. Other activities of the group include delineating lithospheric structures under various Indian crustal blocks and shear zones/active faults and evolution of Quaternary landscapes.
To realize their objectives the group takes help of field, geophysical, geochronological and geochemical investigations. The group is equipped with some of the state of the art geophysical instruments to carry our seismic, gravity, resistivity, and magnetic surveys. The group also houses sophisticated equipment to analyze major and trace element contents and ratio of radiogenic and stable isotopes in solid and liquid samples, apart from determining formation ages of minerals using U-Pb in situ measurement techniques.
Dr. Srikumar Chattopadhyay
About
Dr. Srikumar Chattopadhyay retired from CESS as Scientist G and Head, Resources Analysis Division. He obtained his M. Sc & Ph. D degree in Geography from the University of Calcutta and Post Graduate diploma in Applied Geomorphology and Environmental Survey from the International Institute of Aerospace Survey and Earth Sciences (ITC), The Netherlands. He was a Post-Doctoral Fulbright Fellow in the Environment and Policy Institute, East West Centre, Hawaii, USA. Recipient of Dr. S Vasudev award (1994) instituted by the Kerala State Council for Science, Technology and Environment, Government of Kerala, and Prof. R N Dubey memorial award (2001) instituted by the Boovigyan Vikas Foundation, New Delhi. After retirement from CESS in 2013 he was awarded Senior Fellow position by ICSSR hosted in the Centre for Development Studies (CDS), Thiruvananthapuram. In 2016, he served as a Fellow in the HWK Institute for Advanced Studies, Delmenhorst, Germany. He also worked as a Senior Consultant, Kerala Development Innovation Strategic Council (K-Disc), Government of Kerala, Thiruvananthapuram.
Dr. Chattopadhyay’s work area covers natural and environmental resource management, terrain analysis, human dimension of environmental change, participatory local level planning, and sustainable development. He contributed substantially in evolving Participatory Panchayat Resource Mapping and River Bank Mapping programmes, which were widely acclaimed. He served as visiting faculty in the Department of Geography and Environmental Studies, Montclair State University, New Jersey, USA; Leibnitz Centre for Tropical Marine Ecology (ZMT), Bremen, Germany and several other Indian Universities including Delhi, Calcutta, Mumbai, Burdwan, and Vidyasagar. He has produced more than 100 research papers, authored/ edited eight books, one Atlas and completed 40 research projects funded by the state, national and international agencies. He executed Tri-Academy (Chinese Science Academy, Indian National Science Academy and US National Science Foundation) collaborative project on Population pressure and land use change: Case studies from China, India and USA; Asian Development Bank’s multi country project on Integrated Coastal Zone Management and Poverty Alleviation; and the National Science Foundation of Sri Lanka and Asia Pacific Network collaborative programme in South Asia on ‘Science policy integration for enhanced management of coastal systems’. He hosted Ph. D student from the University of Poiters, France under Indo French cultural exchange fellowship programme and collaborated with ZMT, Bremen, Germany and the Department of Geography, Lancaster University, UK for conducting joint projects, exchange visit and hosting MS students to conduct field studies and dissertation work. Several Ph. D and MS students from India and abroad completed their theses under his guidance. Dr. Chattopadhyay served in various committees, academic bodies and professional organizations both at the national and state level. He has now joined NCESS as ICSSR National Fellow for a period of two years.
Lightning Detection Network
The National Centre for Earth Science Studies (NCESS), Ministry of Earth Science, Govt of India, Thiruvananthapuram installed the Lightning Detection Network (Make: Earth Networks, USA), across southwest India in collaboration with Indian Institute of Tropical Meteorology, Pune. The sensors detect the flash rate per second, position (latitude and longitude) and type of lighting (Intra cloud and cloud to ground; IC or CG) over the region. The detection is based on the time of arrival technique (TAO).
Sensor and accessory details
Lightning sensor : Earth Networks Lightning Sensor
Types of Lightning Detected : Cloud-to-Ground (CG) and In-Cloud (IC) strokes.
Sensor Radio Frequency Bandwidth : 1 Hz to 12 MHz.
Location Accuracy in southwest India : <100 meters (density dependent).
Detection Efficiency’s : > 95%; IC: > 85% (density dependent).
Sensor Baseline in south India : 50 km to 160 km.
Method : Time of arrival (of radio waves).
Sensor Timing Accuracy : <15 nanoseconds.
UPS unit : Hykon 1KVA unit with two 75 AH Exide batteries.
Internet : BSNL FTTH connection and accessories.
