Inaugural Lecture | 23 March 2021
Importance of Geological knowledge – from grade school to graduate school - by Prof Raja V Ramani
At the present time, there is increasing realization that life on Earth is threatened by numerous safety, security and sustainability issues and that concerted action is essential to develop strategies that are effective in the long term. Geology is defined as the scientific study of the origin of the Earth along with its rocks, minerals, landforms, and life forms, and of the processes that have affected them over the course of the Earth's history. It is often said that all human resource needs must be addressed by the basic industries of mining and agriculture and their contributions to the secondary and tertiary industries of manufacturing and commerce. Clearly, it is important to understand how Earth works as a system, particularly how the natural and human processes interact with each other within the system, to manage the system for the benefit of mankind. As our ability to see and collect data from far away in space and from deep in the bowels of Earth has increased, we have also come to appreciate the need for better understanding of the complexity of the interactions of the land, water and atmospheric components of Earth. Knowledge in geology has been considered essential in several fields of science and engineering though its relevance to every human being and to every day life is not widespread in the general public or even in some decision-makers. The purposes of this presentation are to overview the development of geology from the early years to the present and to productive avenues for enhancing geological knowledge from grade school to graduate school.

Second Lecture | 20 July 2021
How is Antarctica changing and why should we care - by Prof Martin Siegert
For more than 2000 years we have been fascinated by the discovery and exploration of Antarctica. The idea of Terra Australis Incognita (the Unknown Southern Land) began with the ancient Greeks, who argued a southern landmass was required to balance the northern world. This quest for knowledge led to the second voyage of Captain Cook in the late eighteenth Century, heroic expeditions by Robert Scott, Ernest Shackleton and Douglas Mawson, and the post-WW2 scientific collaboration of the International Geophysical Year in 1957-8. While much is now known about Antarctica, it still remains unquestionably the most unexplored region on Earth. In this lecture, I will talk about how our appreciation of Antarctica has changed as a consequence of the technological advances required for its scientific exploration. I will show how the perception of Antarctica as a static, lifeless continent has transformed to that of a dynamic region that has the power to alter our global environment. Finally, I will question what changes in the Antarctic could mean for us, and why it should concern everyone.

Third Lecture | 27 Oct 2021
How India Parted Company from Gondwana : Constraints of Space and Time - by Prof Colin Reeves
India formed an integral part of the Gondwana ‘supercontinent’ throughout Paleozoic times. Disruption of Gondwana started early in the Jurassic but it was not until late in the Cretaceous, 100 myr later, that India began its well-known rapid journey northwards, eventually to collide with Asia and form the Himalaya. Data from the southern oceans – primarily ocean-floor topography and marine magnetic anomalies – have been used to investigate (a) the precise configuration of the present-day continents within reassembled Gondwana and (b) the processes of disruption that determined the paleogeography of the southern continents in the 100 myr interval from 184.2 Ma (start Toarcian) to 83.64 Ma (C34, start Campanian). The most recent 40 myr of this interval (i.e. 121.4 to 83.64 Ma) are devoid of marine magnetic anomalies and so demand some conservative plate-tectonic assumptions in addition to careful interpretation of the ocean-floor topography created. Plate-tectonic modelling software (Atlas, Cambridge) has been used to model both continental positions and the likely geometry and behaviour of the mid-ocean ridges across the entire Gondwana-wide system of plates from the onset of disruption to 83.64 Ma, by which time India had begun its rapid northward journey. From this analysis it emerges that initial disruption into East and West Gondwana accelerated early in the Cretaceous (from 142.3 Ma, Berriasian). By 121.4 Ma (M0, start Aptian) most of the well-known continental outlines had been established, many of them in the shorter interval 130-125 Ma (Hauterivian-Barremian). These events are attributed to the more-or-less simultaneous outbreak at this time of the Kerguelen and Tristan mantle plumes. The former created the (Greater) India-Australia-Antarctica triple junction, the latter started the main phase of South Atlantic opening. At about the same time, re-invigoration of the Bouvet plume, located perpetually midway between Africa and Antarctica (and responsible for the original 184 Ma Gondwana disruption) ensured continuity of new mid-ocean ridge systems from West Africa to western Australia, a distance of more than 11 000 km, by Albian times. From early in the Cretaceous the entire India plate, confined at its southern continental tip (along with Sri Lanka) between Africa (including Madagascar) and Antarctica, rotated counter-clockwise by way of two major dextral strike-slip transforms, one off western Australia and the other off Arabia-Somalia. This continued until an ‘escape route’ to the north became possible at about 90 Ma (Turonian) with the outbreak of the Marion plume. The work has been conducted under the umbrella of IGCP-628 (www.gondwana.geologia.ufrj.br/en/) which will shortly publish the new geological map of Gondwana. Animations and explanatory text concerning the work described here may be found at www.reeves.nl/gondwana. The timescale of GTS2020 (www.timescalefoundation.org) has been used throughout.

Landslide Scenarios and Studies in India – A Review
Dr. Saibal Ghosh, Deputy Director General (Geology), GSI, ER, Kolkata
The extra-peninsular terrain of India and its neighboring nations are known hot spots for landslide hazards. Nearly 4.34 lakh km2 areas in the country in parts of 18 States/ UTs are prone to landslide hazards.
Already more than 70,000 historic landslides have so far been inventoried in India by the nodal agency for landslide hazards – the Geological Survey of India (GSI). About 1000s of landslides of varied dimensions, and varied failure mechanisms do occur in such hilly/ mountainous terrains every year.
These landslides are mostly triggered by monsoon rainfall, a few by earthquakes of magnitude 5.0 or more, or as a domino effect because of multi-hazards (flood, avalanche, glacial or landslide lake burst, earthquake etc.).
In addition to the above, landslides are also triggered by anthropogenic actions like toe cutting/ excavation during hill road widening and construction, construction of buildings and other civil infrastructures in hills, etc. Off late, it is also observed that due to the frequent climatic extremes, and unpredictable hydro-meteorological situations, frequency of landslide occurrences, even fatal are increasing nowadays, which is a real concern to the sustainability of the mountainous areas.
Given the above challenges, it is apparent that landslides in the Indian extra-peninsular regions warrant detailed studies. The nodal agency (GSI) and other institutes like IITs, CSIR Institutes, NRSC and other central Institutes are engaged in varied types of landslide investigations since centuries with an ultimate aim to mitigate and minimise the landslide risks.
With the above background in mind, in this lecture, we will steer our discussion through the following major threads to offer a synoptic picture on landslide studies in India
i) Landslide hazard and risk scenarios – International and National perspectives,
ii) Approach of landslide studies and objectives in India,
iii) Role and contributions of nodal agency,
iv) Details of legacy data that are available for further R&D and use,
v) Trends in modern R&D activities on landslides by other stakeholder organisations,
vi) Gap in knowledge and challenges,
vii) Scope and utility of a national geodatabase for managing such hazards,
viii) Ongoing endeavours on landslide early warning, and
ix) State-of-the-art terrain-specific engineering solutions offered for typical problem sites,
x) Possible way forward.

Fifth Lecture | 14 Jul 2022
Importance of Deep-Sea Technology and Ocean Science for India’s Economy - Dr. S. Satheesh Chandra Shenoi, FASc., FNASc.
The ocean is the largest ecosystem of our planet, regulating change and variability in the climate system and supporting the global economy, nutrition, health and wellbeing, water supply and energy. Holds an estimated 80% of Earth’s mineral resources, produces half of the oxygen we breath and meets about 15% of the protein requirement of 70% of world’s population. The coastal zone is home to about 40% of world’s population and provides habitat for 80% of the living organisms in the world. The top 10 feet of the ocean holds as much heat the entire atmosphere.
Indian coastline running over 7500 km is home to nine coastal states and 1382 islands. The country has 12 major ports and 187 non-major ports, handling about 1400 million tons of cargo every year, as 95% of India’s trade by volume transits by sea. India’s Exclusive Economic Zone of over 2.2 million square km is rich in living and non-living resources and holds significant recoverable resources of crude oil natural gas, Placer Minerals (Ilmenite, Rutile, Magnetite, Sillimanite, Garnet, Zircon, Monazite) and Limemud. The coast also sustains over 4 millionfishermen and other coastal communities. India also has exclusive rights of exploration in 75000 square km area for polymetallic nodule deposits in the international water of Central Indian Ocean seabed and 10000 square km area for polymetallic sulphides in the Southwest Indian Ocean. With these vast maritime interests, the Blue Economy in India has a vital relationship with the nation’s economic growth. Currently, the size of the Blue Economy in India is conservatively estimated to be about 4% of Gross Domestic Product. But the current thinking is that that needs to be tripled or quadrupled by sustained development of technology and scientific knowledge.
This talk examines some of the technological developments in the country for deep sea exploration, mining, offshore energy, freshwater generation, etc. and the development of scientific knowledge that helps in predicting weather, climate and ocean genic hazards (storm surges, tsunamis, etc.) that affect the economy and lives. Talk concludes with underlining the necessity for sustainable development to create an healthier better managed ocean for the wellbeing of all.

Ecosystem Restoration - Sri Syed Khalil
Deciphering complexities of ecosystem degradation anywhere is a daunting task, selecting a suitable restoration strategy thereon is more so since a suggested course of action has to meet the exalted standards of scientific sustainability, financial viability and even social accountability. In addition, its real and/or potential benefits need to be convincing enough to the affected populace.
World over, several nations including India are grappling with ecological problems/potential disasters of divergent hues and have been adopting solutions with varying degrees of success commensurate with their resources and of course limitations. Rapid developmental activity is occurring everywhere with huge risk of damaging ecological balance and creating vulnerable infrastructure. This has necessitated adoption of already executed common template on which restoration strategies in other regions/domains have been planned and implemented.
Understandably managing complex ecosystem environments of coastal Louisiana in which the natural and socio-economic systems are highly integrated is inherently difficult. In addition, deltaic environs are uniquely challenged due to the interdependence and delicate balance of water, land and economic systems and future uncertainties regarding the magnitude and rate of climate change impacts. In this context a peep into Louisiana State’s Holistic Sediment Management Plan for a Sustainable Ecosystem Restoration of a Degrading Delta Plain can be instructive.
Syed Khalil proposes to take us through different stages of conceptualization, planning and execution of over two decades of this fascinating project to create, conserve, and preserve land, to mitigate the perennial and catastrophic impacts of land loss to millions of people in coastal Louisiana. Khalil would also emphasis the dictum that despite an acceptable common template the ecosystem restoration strategies are complex, unique and one of a kind where adaptive management plays a key role in every aspect of execution of such large-scale efforts.
ABOUT THE SPEAKER
Sri Syed Khalil hails from Gaya District, Bihar and obtained his M.Sc (Geology) degree from the Patna University. He joined the Geological Survey of India and worked extensively as a land geologist in Central and Eastern India before migrating to the Marine wing as a Geologist (Sr.) and he was promoted as Director. He was a UN Fellow at the University of Hawaii (Honolulu), USA working mainly on deep-sea swath bathymetric surveys around Hawaiian Islands for ferro-manganese crust exploration (SeaMARC II).
He then migrated to the United States and obtained an M.S. degree in Coastal Geology from the prestigious Florida Atlantic Research University. His area of interests are seafloor mapping via integrated coastal/marine geoscientific surveys, coastal zone management, sediment evaluation, regional sediment management for coastal restoration, and geoscientific data management.
Khalil’s primary focus is on the geo-scientific issues pertaining to restoration, mitigation and management of the Louisiana coastal environment to address severe and chronic wetland loss. Concurrently, he is also responsible for development/implementation of an expansive Adaptive Management Program as a co-Program Director. This includes implementation of SWAMP (System Wide Assessment & Monitoring Program) - an overarching monitoring and assessment program for the entire coast of Louisiana documenting changes in various critical areas, including: physical terrain; water quality; waves and currents; and. biotic integrity.
Khalil has conducted numerous integrated oceanographic and hydrographic surveys involving seafloor mapping of the world’s major water bodies including the Pacific, Mid-Atlantic, and Indian Oceans, the Arabian, Andaman, Mediterranean, Japan, and South China Seas, and the Bay of Bengal and Gulf of Mexico.
He has published numerous professional papers in international scientific journals besides being the editor/Associate editor.
