Geoscience is an umbrella term which represents varied subjects of geologic sciences like geology, geophysics, geo-chemistry, and related disciplines. Geoscience is the study of earth and other non organic components that compose it. Among different disciplines of geoscience, geology is certainly the leading discipline which is also responsible for some other subjects like geophysics and geochemistry. Geo science deals with structure, composition and other physical characteristics of the earth. It is a very interesting subject that gives us a glimpse of the great complexity inherent in the natural world. It is a highly specialized subject that provides us with an enormous amount of information of practical value while revealing much about the world in which we dwell.
The role of a geoscientist is very detailed and covers several aspects of our geologic past and present using complex instruments. The demand for qualified geologists has increased tremendously in recent times because of their searching abilities in finding natural resources such as petroleum, metals, and water. Their services are constantly sought by governmental agencies and exploration firms. The job profile of a geoscientist extends to a wide range of activities including categorizing and examining rocks and conduct geological surveys. He/she also inspects the information collected by satellites. A geoscientist has special instruments at his disposal to calculate the gravity and magnetic field of the earth in addition to creating the field maps.
Usually, geoscientists specialize in a specific field of geoscience. It could be geochemistry, geology, oceanography or geophysics. Studying the seismic signals of earthquakes is also performed by these well trained professionals. Such studies help them in comprehending the structure of Earth’s sub layers and to search for oil and gas. Additionally, geoscientists cater to study of animals and plant life by researching on fossil remains and laboratory specimens.
To become a geoscientist, one needs at least a bachelor degree, but ideally, top level geoscientists have master degree in geoscience, earth science, geology, or other related field. Those interested in research positions must have a doctorate degree. The course curriculum for geoscience covers subjects like biology, geology, petrology, mathematics, physics, mineralogy and paleontology. Once they complete the course, they need to obtain requisite license. As mentioned earlier, the demand for talented geoscientists is pretty high. Job growth is expected to be driven further with need for water management, environmental protection, energy, and responsible land. They can seek employment opportunities in scientific and management consulting and engineering services industries.
Those who wish to pursue geoscience in India need to complete their M.Sc or M.Tech in any subjects of geoscience.
Some of the reputed institutions offering courses in geoscience and related fields are:-
Anna University, Chennai
Bharathidasan University, Tiruchirapalli
Indian School of Mines, Dhanbad
Dr. Harisingh Gour Vishwavidyalaya, Sagar
Guru Nanak Dev University, Amritsar
Cochin University of Science & Technology, Kochi
Interested candidates can go for subjects like atmospheric sciences, meteorology, oceanography, marine geology, geology, geophysics and geochemistry etc. Job opportunities are available with central government agencies, coal and mining companies, oil exploration firms and even defense forces.
