Department of Earth Sciences

Department of Earth Sciences constituted in 1982 from erstwhile Geology Section of Department of Civil Engineering, the Department of Earth Science at IIT Bombay completed its silver jubilee in the year 2008. The department is committed to providing leadership in academics and in cutting-edge research in all branches of Earth Sciences.

The Department of Earth Sciences offers academic programmes leading to M.Sc. in Applied Geology and Applied Geophysics, M.Tech in Geo-exploration and Petroleum Geosciences, and Doctoral Degrees in various field. The entire core, additional and elective courses included in the department has been specifically designed to meet industry standards and research requirements. The close links that the department enjoys with the industry and research organizations, has worked towards elevating the quality of studies and facilities. The department also works towards building the social and moral character of the students. Research work is conducted mainly in the areas of geo-thermics, aiming at the evaluation of the geo-thermal energy potential of our country.

Demonstration of Thermal (Remote) Sensing
Remote sensing from satellites, aircrafts has greatly enhanced how the variation in soil thermal properties can be identified and utilized to benefit many aspects of human endeavor. While remote sensing of reflected light from surfaces does indicate thermal response of the topmost layers of soil (a few molecular layers thick), it is thermal infrared wavelength that provides energy variations extending to varying shallow depths below the ground surface which is of most interest. A thermal sensor can detect variations to heat transfers into and out of near surface layers because of external heating by the thermal processes of conduction, convection, and radiation. Thermal infrared radiation is also used to identify buried objects using Infrared(IR) Camera.

Demonstration of LiDAR
LiDAR (Light Detection and Ranging, 3D laser scanning, is an emerging three dimensional mapping technology that employs a laser and a rotating mirror or housing to rapidly scan and image volumes and surficial areas such as rock slopes and outcrops, buildings, bridges and other natural and man-made objects. It enables to determine detailed information about rock discontinuity orientation, roughness, length, spacing and block size accurately.

Demonstration of Exploring the Moon Using Imaging Spectroscopy
Imaging spectroscopy (hyperspectral or spectral imaging) is similar to color photography, but each pixel acquires many bands of light intensity data from the spectrum, instead of just the three bands of the RGB color model. More precisely, it is the simultaneous acquisition of spatially coregistered images in many spectrally contiguous bands. This demonstration includes the philosophy of Imaging Specroscopy and how this technique was used to explore the moon’s surface during the Chandrayaan-I mission.

How the Strength of a Foundation is Estimated
This demonstrates different procedures involved in estimating the strength of foundation rocks.

A Live Demonstration of Geophysical Survey (Electric/Seismic)
Geophysical survey is the systematic collection of geophysical data for spatial studies.Geophysical surveys may use a great variety of sensing instruments, and the data may be collected from above or below the Earth's surface or from aerial or marine platforms. Geophysical surveys have many applications in Earth science, archaeology, mineral and energy exploration, and engineering. They are used in industry as well as for academic research.
