A GIS Approach to Identify Potential Zones of Polymetallic Nodules in The Indian Ocean Region
Abstract: Mankind’s quest for metals has been growing steadily and has resulted in expanding his search beyond land, that is, in the oceans. Being in the dissolved form, metals are also formed in the ocean in the form of polymetallic nodules. They are submarine rock concretions formed of concentric layers of Iron and Manganese hydroxide around a nucleus. Nodules contain manganese and iron, nickel, copper, cobalt, lead, molybdenum, cadmium, vanadium, titanium, …

Western Indian Ocean and Impacts of SDG14: Life Below Water
Abstract: The SDGs outline a sustainable and inclusive global future. This paper discusses progress toward SDG 14 within the WIO, emphasizing four targets that were set for achievement by 2020. Given that current methods of evaluation of policy-informing lack precision, in this region, little headway has been made toward meeting the set targets, and the attainment of SDG 14 by 2030 does not seem possible. SDG 14.2 and 14.5: Moving at …

Geological and Geophysical Studies of the Ninety East Ridge: A Brief Review
Abstract: The Indian Ocean serves as a unique laboratory for studying the impact of both global and regional stressors on environmental changes over various geological epochs. Its distinct hydrological conditions and geographical location make it an ideal focal point for research into these phenomena. Of particular interest within the Indian Ocean is the Ninety East Ridge (NER), which holds significance as the world's longest linear rise. Researchers have long hypothesized that …

Plastic Pollution from River to Ocean: A Comprehensive Review in Indian Scenario
Abstract: Plastic represents a substantial environmental hazard, contributing to contamination of terrestrial,aquatic, and atmospheric ecosystems. This category comprises a diverse range of polymers. In the formof microplastics and nanoplastics, it can induce toxicity in water bodies. Plastic debris not onlyphysically pollutes freshwater, but also chemically, undergoing changes over time due to hydroclimaticeffects. Rivers serve as conduits, transporting plastics from minor tributaries to major rivers andultimately into the ocean, endangering marine life. …

Impact of Marine Pollution Threats and Conservation of Marine Biodiversity
Abstract: Ocean occupies 71% of earth’s surface and is traditionally divided into four large basins including North and South Atlantic, North and South Pacific, Arctic and Indian oceans. In India we have a vast coastal area of 7516.6 km from Kolkata to Gujarat and also many islands including Andaman and Nicobar and Lakshadweep with vast fin and shellfish biodiversity. Human interference and both natural and artificial factors pose the biggest threat …

India's Vanishing Marine Wealth: Ecosystems Under Threat from Development
Abstract: The Indian Ocean is one of the world’s most important oceans, covering about a fifth of the globe’s total ocean area. It is also home to some of the world’s most valuable fisheries, as well as a wealth of other marine life. However, this development is coming at the cost of the delicate marine environment. Numerous studies have shown that the increased shipping traffic, coastal construction, and pollution are harming …

Variation In Wave Steepness and Wave Age-A Case Study in The Arabian Sea from Buoy Measurements During Post-Monsoon
Abstract: The National Institute of Ocean Technology (NIOT) moored buoy measurements in the Central Arabian Sea (AS) at AD07 location (68.87 E, 15.07 N) during the year 2015 are utilized to understand wind and wave growth characteristics at this location during the post- monsoon season covering the three-month period from October to December (OND). The wave direction followed the wind from Northeast while the swells were predominantly from the Southern Indian …

Association of ENSO and IOD with Summer Monsoon Rainfall Variability over Central India
Abstract: Present study aims to unfold the trend of summer monsoon (JJAS) rainfall for past 114 years (1901–2014) over central India (16.5°N to 26.5° N, 74.5°E to 86.5°E). Further its variability over a long-term time-scale and association with ENSO (El Niño Southern Oscillation) and IOD (Indian Ocean Dipole) like events and further investigated that has more significant association. Due to a significant contribution of summer monsoon (JJAS) rainfall to annual rainfall, …

Role of Satellite Data Assimilation on ERA-Interim and ERA5 Wave Parameter Ratios – A Case Study based on Year-long In-Situ Observations in the Bay of Bengal
Abstract: The rapid decline in the energy resources forced mankind to tap other forms of natural energy resources in the light of exponential increase in the demand due to over-population. The energy from ocean waves is one of the cleanest sources of energy available perennially that changes seasonally and is site-specific. To assess the wave power potential at any site, knowledge of the wave parameters such as wave height, period and …

Structural Design of Offshore Structures: A Review of Indian and International Standards
Abstract: Offshore structures—including fixed steel jackets, topside modules, offshore wind turbine support structures, and floating systems—are designed to withstand combined gravity, environmental, seismic, and operational loads under substantial uncertainty and limited access for inspection and repair. Structural design practice has historically relied on internationally recognized standards, particularly the American Petroleum Institute’s API RP 2A, the International Organization for Standardization’s ISO 19900 series, including ISO 19902 for fixed steel structures, and Det …

Observed Seasonal Variation Of Wave Power From Moored Buoy Measurements - A Case Study On The East Coast of India
Abstract: The wave climate in Indian waters is strongly influenced by the seasonal variation. Accurate wave height assessment is crucial for wave power computation which is proportional to square of the significant wave height. Any error in wave height is magnified in the wave power estimation. Wave models tend to predict medium range wave activity to a desired degree. Insufficient wind, bathymetry and grid resolutions, model physics parameterizations also account for …
