# Kolluru Sree Krishna

Kolluru Sree Krishna (born 1958) is an Indian marine geophysicist and former chief scientist at the National Institute of Oceanography, India. He is known for his studies on the evolution of the Indian Ocean and is an elected fellow of all the three major Indian science academies: Indian National Science Academy, Indian Academy of Sciences, and the National Academy of Sciences, India. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards for his contributions to Earth, Atmosphere, Ocean and Planetary Sciences in 2001.

## Biography

K. Sree Krishna, born on 15 October 1958, in the south Indian state of Andhra Pradesh, graduated in science from Andhra University in 1979 and completed his master's degree in geophysics from the same university in 1982. He started his career as a seismologist at Geophysical Service Inc., a subsidiary of Texas Instruments, in 1983 when the company was involved in the hydrocarbon explorations in the basins of Krishna-Godavari and Cauveri rivers and spent one year with the company. In 1984, he joined the National Institute of Oceanography, Goa (NIO) as a B-grade scientist where he holds the post of the chief scientist since 2009. In between, he held several scientist positions at NIO and also secured a PhD from Andhra University in 1996.

## Legacy

One of the most important contributions of Krishna is his studies on the evolution of Indian Ocean on which he developed tectonic models and validated the same. He conducted extensive studies on the lithospheric studies of the central Indian Ocean in relation to the uplift of the Himalayas and on the primary hotspots of the global oceans and mantle circulation for which he has undertaken ocean expeditions. His studies assisted in a wider understanding about the relationship between the rise of the Himalayas, the sedimentation in the Bay of Bengal and the Indian monsoon. His studies have been detailed in several peer-reviewed articles; ResearchGate, an online repository of scientific articles, has listed 85 of them.
Krishna was the convenor of the Fall Meeting of the American Geophysical Union in 2015 where he chaired the session on 16 December 2015 and presented a paper on Sediment dispersal pattern in the Bay of Bengal - evidence for commencement of Bengal Fan sedimentation. He has also been associated with several science journals; he served as the associate editor of the Solid Earth section of the Journal of Geophysical Research published by the American Geophysical Union from 2005 to 2010 and sat in the editorial boards of Indian Journal of Marine Sciences (2008–10), Proceedings of the Indian National Science Academy (2015) and the Association of Exploration Geophysicists (2015).

## Awards and honors

Sree Krishna received the Krishnan Medal of the Indian Geophysical Union in 1996; IGU would honor him again in 2010 with its Decennial Award. In between, the Council of Scientific and Industrial Research awarded him the Shanti Swarup Bhatnagar Prize, one of the highest Indian science awards in 2001. The year 2010 brought him another award in the form of the National Geosciences Award of the Ministry of Mines and he received the inaugural Annie Talwani Memorial Prize of the Indian Geophysical Union in 2013.
Krishna held two fellowships of the Royal Society of London; the INSA-Royal Society fellowship in 1999 and the international fellowship in 2008. The Indian Academy of Sciences elected him as its fellow in 2002 and the other two major Indian science academies, the National Academy of Sciences, India and the Indian National Science Academy followed suit in 2010 and 2013 respectively. He is also an elected fellow of the Indian Geophysical Union (2002) and the Andhra Pradesh Akademi of Sciences (2011). He also held the J. C. Bose National Fellowship of the Department of Science and Technology in 2012 and the award orations delivered by him include the 2016 S. Balakrishna Memorial Lecture of the Telangana Academy of Sciences.
