Dr. Sergey Vasilyevich Goldin (28 January 1936 – 18 May 2007) was a Soviet and Russian geophysicist, Academician of RAS, member of European Academy of Science and American Geophysical Union, director of Institute of Geophysics in Sibiria Branch of RAS (1996- 2004).[1]

Memorial

Academician Sergey Goldin—world-renowned geophysicist, exceptionally bright and creative scientist, and outstanding educator—passed away on 18 May 2007. Sergey Goldin was born in St. Petersburg, Russia, on 28 January 1936. He graduated with honors from St. Petersburg School of Mines in 1958. He began his professional activity in Western Siberia as an exploration geophysicist and he eventually became a party chief. During this time, he became interested in seismic research and completed a PhD thesis on statistical methods of seismic processing and signal detection.[2]

In 1970, he was invited to lead a small laboratory in the Geophysical Institute of the Siberian branch of the Soviet Academy of Sciences in Academgorodok near Novosibirsk. In that same year, he started to teach a course on statistical methods of seismic data processing in Novosibirsk University. This had an enormous impact and changed the focus of geophysical instruction at the university. Today, many of his former students are prominent in the geophysical industry and in academia in many parts of the world.

Sergey Goldin founded two scientific schools during his work at the Russian Academy of Sciences in Novosibirsk. One school is dedicated to developing the theory of forward and inverse modeling of seismic wave propagation in heterogeneous and fluid-saturated media. The other aims at understanding and describing the processes occurring at earthquake focuses and attempts to predict earthquakes.

Goldin began to develop, along with his students and perhaps for the first time in the world, methods for nonlinear traveltime inversion. He published his first book, Linear Systems of Signal Processing, in 1979 and became a doctor of science, the highest scientific degree in the Soviet Union, in that same year.

He became director of the Geophysical Institute in 2000 and published the book Traveltime Inversion which was translated into English by SEG. After the fall of the Soviet Union, Goldin received many teaching invitations from around the world. He began to travel extensively and lectured in the United States, Norway, Brazil, and China.

Goldin had two passions in addition to science, art, and sports. He was a skilled performer on the mandolin on which he played folk, chansons, and classical music. He also played the piano, painted, took up photography, and wrote poems and songs. He was an excellent volleyball player and loved skiing. All of this was done with enthusiasm and passion.

We will remember Sergey Goldin as an intelligent and kind person and a poet, who was always fond of the beauty of our world.

Biography

In 1953 S. Goldin has completed secondary school in Vologda with a silver medal award. In the same year he has arrived on geophysical faculty of the Leningrad Mining Institute which has ended in 1958 with the high distinction. In the next three years he was employed in field geological parties in Kolpashevo, Surgut and Berezovo (all in Siberia), participated in the opening of an oil deposit near to Surgut.

In 1961 S. Goldin has arrived in postgraduate study of Institute of geology and geophysics SB of AS USSR. Since 1964 he was the research assistant of the Institute. In 1966 has defended the PhD thesis of physical and mathematical sciences on the theme of The Noise stability of algorithms of phase correlation of seismic waves against disturbances».

In 1965 S. Goldin has lived to Tyumen and had headed laboratory of mathematical processing of Western-Siberian scientifically - research geology-prospecting oil institute. In this time he has started to teach at the Tyumen industrial institute.

In 1970 S. Goldin has come back to Novosibirsk, had headed laboratory of mathematical methods of geophysics in the Institute of geology and geophysics of SB AS USSR.

In 1979 he has defended the thesis for a doctor's degree (on physical and mathematical sciences), with a theme Kinematic interpretation of the reflected seismic waves (the theory and algorithms)». Since 1971 S. Goldin taught on chair of geophysics of Novosibirsk State University (NSU). In 1983 S.V.Goldinu appropriates a rank of the professor, since 1990 supervised over chair of geophysics in NSU.

In 1991 he has been selected by member-correspondent of the AS USSR, and in 1997 - the full member of the Russian Academy of Sciences. With 1996 for 2004 S. V.Goldin has been selected as director of Institute of geophysics of the Siberian Branch of the Russian Academy of Science.

Scientific achievements

He was author more than 200 scientific publication, among which were 4 monographs.

Among his pupils are of 3 doctors and 25 PhD of science.

S. V.Goldin possesses among other the theory of the seismic migration allowing quantitatively to compare various algorithms of construction of the plotting of medium and to synthesise algorithms with set properties.[3]

Last years the scientist dealt with problems of geophysics new to: experimental and theoretical studying of the nonlinear effects bound to diffusion of seismic waves in heterogenous mediums, studying of physical processes in the seismic source and the forecast of earthquakes.

In the beginning of 2000-th years S. V.Goldin has offered the new concept of geophysical and geodynamic monitoring of the seismoawake regions, embodying strategy of the short-term forecast of earthquakes offered it earlier. The essence of new strategy consisted in priority conduction to researches from search for earthquake tremors on studying of the geomechanical and physical processes descending in concrete blocks massives in the place of source.[4][5]

At the last years of the life he has put forward essentially new geodynamic problems of the physical processes descending in the seismic source in the course of prediction of earthquake, during time and after its realisation.[6] According to this theory, in the source a series accomodation processes which allow medium "to adapt (to any limen)" to increasing loads and in which such specific properties of block mediums, as ability to repacking, to quasiplastic flow, to dilatant strengthening, and also the phenomenon of dynamic convertibility of dilatacy, leading to formation of mesostrictures in sourse earthquake areas are awakely displayed educes.[7]

He died in Novosibirsk Russia.
