Indian Geophysical
Union had always promoted this endeavor of YES by supporting a large number of
young researchers to participate in its Annual Convention since 2011. The 50th
convention of Indian Geophysical Union [www.igu.org] was held during 8th
-12th January, 2014 at National Geophysical Research Institute,
Hyderabad. The conference was jointly organized by the Indian Geophysical Union
(IGU) and CSIR-National Geophysical Research Institute, Hyderabad. Main theme
of the convention was “Sustainability of Earth System-The Future Challenges”.
The convention was inaugurated by Noble laureate Prof. Y.T. Lee, President of International Council of Science (ICSU), accompanied
by Prof. Carol Finn, President American Geophysical Union (AGU), Prof. V.P.
Dimri President Indian Geophysical Union (IGU), Prof. H.K. Gupta, Member,
National Disaster Management Authority of India, Prof. Mrinal K.Sein and Prof. Shailesh
Nayak.
The number of YES members from Indian chapter is increasing manifold. There were more than 50 YES members who participated in 50th Convention of IGU. In total there were 19 poster presentations from students coming from Indian Institute of Science Education and Research (IISER) Kolkata, Indian School of Mines (ISM) Dhanbad, Indian Institute of Technology (IIT) Bombay, CSIR-National Geophysical Research Institute, Kurukshetra University and Institute of Seismological Research (ISR) Gujarat. Apart from these students category, YES members also presented posters in research scholars from CSIR -NGRI, ISR and OIL India Limited. Posters were presented on all geophysical domains.
Out of 19 papers, 5 papers were based on Seismology, 4 were based on Potential Field studies, 3 were based on Remote Sensing, GIS and Groundwater, 3 papers came out with Well Logging and application to well data, instead of these other 4 papers were based on Geology, Microbiology and Environmental studies. In Seismology posters, students talked about estimation of Source Parameters and Attenuation Characteristics from Strong Ground Motion data of different earthquakes. One group talked about Displacement and Strain Displacement during 24th September 2013 Southern Pakistan Earthquake (Mw 7.7). In Potential Field papers, students talked about different approaches i.e. Spectral approach, Fractals on Potential Field Data. Some students presented the application of Remote Sensing and GIS for Integrated Resources and Groundwater. There were some presentations based on Well Logging data and results. There were discussions about Well Log Data Analysis for Coal Bed Delineation and its Proximity Analysis in Jharia Coal Field and also on Rock Physics Modeling. YES participants were amused to know about Diurnal Variations of Ozone (Total Oxidant) at a Burb Site - Tarnaka, Hyderabad by a local student of Hyderabad. There were participation from Microbiology on Molecular Diversity of Bacterial Communities in a Permanently Cold Arctic fjord and Planktonic Cyanobacterial Communities in Sundarbans Mangroves - A Polyphasic Approach.
Panel of experts selected best poster award for students and researchers categories. In both categories, two awards were bagged by IYES members.
Ms. Payal Rani (YES member) from National Geophysical Research Institute won the 2nd award for best poster in student section. She talked about “Spectral Methods for Depth Estimation from Gravity Data: A comparison”. She calculated the depth of causative body which causes gravity anomaly by using spectral approach.The depth of causative body can be estimated from the slope of fitted line to the log of power spectrum versus wavenumber. The power spectra can be calculated using the Fast Fourier Transform (FFT), Maximum Entropy Method (MEM) and Multi Taper Method (MTM). The synthetic as well as field gravity data has been used for checking the efficiency of these methods. She concluded that the depth of geo-bodies estimated using the MTM is closer to actual value as compared to the depth estimated by FFT and MEM approach.
Mr. Shib Shankar Ganguly, (YES Research Scholar) from CSIR-National Geophysical Research Institute won the 2nd award for the best poster in research scholar category. He presented his work on “An Estimation of CO2-EOR potential from a Sector model in a Mature Oil Field, Cambay Basin, India”. He presented a study on the possibility of CO2 enhanced oil recovery (EOR) by CO2 injection in a mature oil field from the Cambay basin, India. For this, a conceptual sector model is constructed and various sensitivity analyses of reservoir parameters, such as grid resolution, residual oil saturation to water, etc. is carried out to understand the CO2 EOR process for the reservoir and observed promising results from the simulation of the conceptual model.
Apart from the above presentations and participation, IYES members interacted with various dignitaries in conference and discuss about the research aspects in Earth Sciences.
