The School of Earth, Ocean, and Atmospheric Sciences (SEOAS) was established by the amalgamation of two departments that are related to planetary studies, viz., Earth Science (established in 1986) and Marine Sciences (1985) to deliver better together. Marine Microbiology, Environmental Science, Atmospheric Science and Remote sensing & GIS were added to the School during the A.Y. 2020-21, 2021-22, 2022-23, respectively.

The significant coupling between lithosphere, atmosphere, hydrosphere, and cryosphere necessitated a holistic approach to study Earth system science that include Marine Sciences, Marine Microbiology, Atmospheric Science, Remote sensing and the environment, highlights the dynamic nature of the Earth system. The daunting task of Oceanographers, Earth Scientists, Marine Microbiologists, Environmentalists and Atmospheric Scientists is to understand the complex dynamics and wade through the present crisis of climate change to create a sustainable environment for the human to survive.

The focus of the school is to provide quality education and research in earth system science through an integrated approach with a view to the deciphering process for sustainable development. Since we have framed our syllabi in tandem with the NET syllabus, our pedagogy makes the courses offered by the school as the most favoured in post graduating earth system science, with strongly inter-disciplinary courses.

The research funding from external agencies are not only a measure of research quality but also a good judgment of the acclaim our faculty members held in academic and research arena. By this metric, we are doing well, as our school has the largest external cash flow amongst the science faculty in GU.

Funding is mainly from Ministry of Earth Sciences (MOEs), Ministry of Shipping, Indian Space Research Organization (ISRO), Naval Research Board (NRB), University Grants Commission (UGC) along with Department of Science and Technology (DST). Outstanding faculty members will be recruited to carry out teaching and research for this programme. This will enable the school to have a strong inter-disciplinary faculty by the end of 2022. In addition to PG programmes, the school will provide the need-based certificate and PG diploma courses. Students registering for the Ph.D. degree will have the option to get a degree in any branch of the earth system science viz; Marine Sciences (Physical Oceanography, Chemical Oceanography, Marine Biology, Marine Geology), Marine Microbiology, Atmospheric Science, Hydrography, Remote Sensing & Geographic Information System, Polar Science and Environmental Science.
