Description: The oceans are essentially the lifeblood of our planet. Their vast expanse supports all types of terrestrial and aquatic life, aids in climate regulation, provides essential resources, and influences global weather patterns. Understanding their crucial role is vital for ensuring a sustainable future. Consequently, monitoring the oceans is an important task, especially the Indian Ocean, which is notably distinct from the other two oceanic basins, namely the Pacific and the Atlantic, and is home to nearly 2.7 billion people in the coastal nations. This session aims to present the existing observational infrastructure in the Indian Ocean, including the Southern Ocean. The observational platforms comprise ground observations from ships and boats, remote observations using autonomous vehicles such as Argo/Bioargo floats, gliders, moorings, and satellites. The session will concentrate on proposing an observational requirement/framework for the Indian Ocean to benefit the Indian Ocean Rim countries, with an emphasis on climate change

Description: Ocean plays a vital role in making the planet habitable by producing roughly 50 % of world oxygen and taking up roughly equal amount to anthropogenic carbon dioxide. Hence, it is important to monitor the ocean for recording any changes resulting due to both natural and anthropogenic processes. The vast remoteness of ocean thus makes this task quite challenging for shipboard measurements which provides limited spatial coverage and repetivity. In recent times, these crucial gaps have been reduced because of remote sensing satellites and autonoums platforms in ocean such as gliders and BGC-Argos. Immense data sets have been generated by these tools on various ocean parameters giving ocean observations a futuristic makeover and also giving the data limited ocean models a new life. In this session we will host various scientific works carried out on ocean observations using tools such as remote sensing and autonomous platforms including data integration for ocean models using machine learning approach.

Description: "This session aims to bring together researchers working across diverse marine zones to share insights on ecology, diversity, and functional roles of benthic communities and their responses to anthropogenic and climatic pressures across the full spectrum of estuarine and marine environments, from coastal zones and continental shelves to the deep-sea and abyssal plains. Benthic ecosystems span estuaries, coastal waters, continental shelves, and the deep sea. They are fundamental to global biogeochemical cycles, providing essential ecosystem services, and acting as crucial indicators of ocean health. Benthic communities also serve as sensitive indicators of environmental change, reflecting the impacts of natural variability, habitat alteration, pollution and climate-driven stressors. We welcome submissions focusing on: • Biodiversity Patterns: Drivers of benthic species richness and composition (e.g., environmental gradients, substrate type, connectivity) across different marine zones. • Ecosystem Functioning: Quantification of key benthic functions, such as bioturbation, secondary production, nutrient cycling, and carbon sequestration. • Community Dynamics: Investigations into species interactions, trophic ecology, resilience to disturbance, and the impact of physical and chemical stressors (e.g., deoxygenation, warming, deep-sea mining). • Environmental Indicators: Employing benthic assemblages as indicators of environmental health and change • Methodological Advances: New approaches in sampling, monitoring, modeling, and 'omics technologies applied to benthic research. The goal is to promote an integrated understanding of how benthic diversity supports ecosystem functioning across diverse marine depth and geographic zones, informing conservation and sustainable management strategies for the ocean floor.

Description: The Gulf of Mannar (GoM) and Palk Bay (PB), located between India and Sri Lanka, are partially separated by Pamban (Rameswaram) Island and a group of submerged sandbars known as Ramsethu (Adams Bridge). The GoM has a wide and open connection to the Arabian Sea (AS) in the west, while the PB has a narrow connection to the Bay of Bengal (BoB) in the east via the shallow Palk Strait. The northern GoM is a designated Marine Biosphere Reserve of India and is known for its high biodiversity potential and ecological sensitivity. But the adjacent PB, although a very shallow, semi-enclosed, quiescent area for most of the year and biologically resourceful, lacks peer-reviewed scientific data on its faunal diversity and richness. This is mainly because there hadn't been much scientific research done for almost 3 decades due to the safety risk of the civil (Ezham) war that Sri Lanka faced from 1983 to 2009. The oceanography of the GoM and the PB has advanced significantly over the past ten years. This advancement was primarily the result of the seasonal field sampling conducted by the CSIR-National Institute of Oceanography (CSIR-NIO), India, associated with the feasibility study of the Sethusamudram Ship Channel proposal considered by the Government of India. There are several research and academic institutions that are currently involved in diverse research aspects linked to the GoM and PB. Therefore, a multidisciplinary session on GoM and PB is proposed, anticipating participation from researchers across various disciplines who are engaged in investigating different aspects of these two ecologically sensitive ecosystems.

Description: "Coral reefs are the most biodiverse and productive ecosystems on Earth, yet they are at risk due to the dual pressures of global climate change and local anthropogenic stressors. Rising sea surface temperatures, ocean acidification, and extreme weather events are driving widespread coral bleaching and mortality, while sedimentation, eutrophication, overfishing, and coastal development compound their vulnerability. These cumulative stressors not only degrade reef ecosystems but also undermine the livelihoods, food security, and cultural heritage of millions of people who depend on them. This session aims to bring together researchers, practitioners, policymakers, and community stakeholders to explore the ecological, socioeconomic, and governance dimensions of coral reef resilience in the face of a rapidly changing world. The discussions will focus on understanding the environmental responses of reef systems to climate stress, the human dimensions of reef degradation, and the pathways toward sustainable, climate-resilient reef management and restoration."

Description: Coastal fisheries are under immense, multifaceted climate stress. This session will integrate the challenges and solutions for national marine resources. The Pressures include shifts in oceanographic dynamics (SST, currents, upwelling) that impact key pelagic species (sardines, anchovies), and biogeochemical stressors like ocean acidification, which threatens shellfish and corals. Furthermore, sea level rise and increased storm intensity degrade critical coastal habitats (mangroves, seagrass, reefs).The Effects span pelagic species migration and altered phenology, alongside demersal impacts like habitat loss and temperature stress on non-migratory species (grouper, shrimp). We will also examine the vulnerability of aquaculture to acidification, eutrophication and the rise of fish diseases and HABs. The Solutions require forward-looking, climate-ready management (dynamic quotas) and building community resilience through livelihood diversification and early warning systems. Crucially, success depends on Ecosystem-based Adaptation (EbA) by protecting and restoring vital coastal habitats.

Description: The Indian Ocean is the smallest of the major oceans. However, ocean dynamics and variability potentially affect half of the global population. One of the fastest-warming tropical ocean basins, the Indian Ocean, has undergone changes in recent decades. These changes have implications for the local and global weather through climate, the extent of which is being understood. Moreover, these changes are further modulated by interactions with other oceans, teleconnections, and Monsoons through several pathways, both in the ocean and the atmosphere. he mechanisms of these interactions are usually complicated and vary over differing time scales. The northern Indian ocean, and its biogeochemistry, are also particularly distinguished by the discharge of large rivers that affect the stratification, and on a slower time scale, exchanges with the Red Sea and Arabian Gulf. This session highlights the changing dynamics and of the Indian Ocean on seasonal, interannual, multi-decadal, or even longer timescales variability and implications. Relevant studies using various new modelling and prediction approaches to study the Indian Ocean are also welcome.

Description: Interactions among the Pacific, Atlantic and Indian Oceans through ocean–atmosphere coupling can initiate and/or modulate climate variability. El Niño-Southern Oscillation (ENSO) is the first climate phenomenon which was hypothesized to be a result of the interaction between the ocean and atmosphere. ENSO affects other oceans through atmospheric bridges and influence on modes of variability in the tropical Indian and Atlantic Oceans, which in turn feed back onto ENSO. Interactions between pairs of modes (ENSO, IOD, PJ pattern, PDO, AMO, IPO) can alter their strength, periodicity, seasonality, and ultimately their predictability. This session will explore the complex dynamics of these three oceans, focusing on their interconnections, feedback mechanisms, and the influence they exert on both regional and global climate. We invite contributions based on observations, modelling, theory and palaeo proxy reconstructions that advance our understanding of Indian Ocean variability, and its influence on the ocean and atmosphere.

Description: "The phenomenon of oxygen minimum zones (OMZs) occurs in all 3 major oceans. In addition to restricting the biodiversity in the open ocean water columns, their occurrence, prevalence and expansion also in the neritic waters is detrimental to the ecology, decimates biodiversity, productivity as a whole. Consequently, OMZs are serious detriments to the local fisheries impacting fisherfolk livelihood. Numerous recent investigations on microbial communities, metabolic diversity and role in cycling of nutrients within the OMZs are revealing many new aspects, some of which are concerning the fixed nitrogen loss from the oceans, green-house gas emissions and sulfidic mineralization in the sediments withing the OMZs. Considerable ambiguity yet exists in both phylogenetic composition, biochemical pathways and the presumed flux of higher concentration of particulate carbon through the OMZ columns. Some predictions claim that with climate change are the expansion of OMZs due to changes in oxygen solubility, microbe-mediated oxidation or respiration. It is appropriate to gain insights on these aspects by convening a dedicated session. At least 10 global researchers with expertise with a focus on climate connections will be invited to deliberate on budgeting the microbial rates, enzymatic pathways transforming various Nitrogen molecules, Sulfur-cycle processes, modulation of Fe/Mn ions, etc. This session will help assemble a pool of contemporary researchers and experts who can educate youngsters, provide insights and directions for ways forward.

Description: The oceans play a critical role in the global carbon cycle, acting as both a reservoir and a long-term sink of atmospheric CO₂. Understanding the mechanisms and efficiency of carbon burial in marine systems is essential for predicting future climate scenarios. Marine sediments archive signals of both marine productivity and terrestrial inputs, providing a unique window into carbon dynamics over a range of temporal and spatial scales. Carbon burial, particularly in marine sediments and coastal ecosystems (such as mangroves, salt marshes) has emerged as a significant pathway for long term carbon sequestration. Despite this, the quantitative assessment, its understanding and spatio-temporal variability of carbon burial are not yet fully elucidated, especially in the context of increasing anthropogenic impacts and environmental change. We encourage contributions that integrate marine and terrestrial perspectives, using various proxies and modelling approaches to better constrain processes of organic and inorganic carbon burial in the oceans.

Hence it is important to establish the magnetic mineral inventory of marine sediments to reconstruct the modern and past environmental changes. This session seeks contributions on the various applications of rock, paleo, bio-and environmental magnetism, including understanding of source-to-sink processes, climate change, iron-biomineralization, depositional, and diagenetic processes and establishment of geomagnetic records in marine system. This session will provides a platform to foster and deepen the interdisciplinary collaboration between the researchers working on understanding of sedimentary processes and geomagnetic variations using magnetic record of marine sediments.

Description: Marine heatwaves (MHWs), periods of prolonged and extreme ocean warming, are emerging as a critical challenge for ecosystems, fisheries, and coastal communities. The Indian Ocean, experiencing some of the fastest warming globally, is highly vulnerable to these events, yet remains underrepresented in marine extreme research compared to the Pacific and Atlantic. This session invites studies that advance understanding of the physical drivers of Indian Ocean MHWs, including roles of the monsoon system, Indian Ocean Dipole, and remote teleconnections. We also welcome contributions on ecological and socio-economic impacts, from coral bleaching and biodiversity loss to risks for fisheries, aquaculture, and tourism. Further emphasis is placed on compounding extremes (e.g., MHWs with deoxygenation, acidification, or rainfall anomalies), forecasting and prediction tools including AI/ML approaches, and adaptation strategies for vulnerable coastal populations. By integrating physical, ecological, and socio-economic perspectives, this session aims to inform science, policy, and sustainable management in the Indian Ocean region.

Description: Interactions among different large-scale ocean-atmosphere coupled modes are exceptionally complex. Diverse scale modes interact through oceanic circulation that cause of latent and sensible heat flux thus affecting weather patterns globally. There regional and remote drivers such as ENSO, IOD, NAO and ASSP and their impacts on the epochs of Indian Summer Monsoon Rainfall (ISMR). The energy budgets caused by the Land-Ocean-Atmosphere; the spatial structure of moisture integration changes the amplitude rainfall patter in monsoon season. The compound changes of ISMR in recent decades and future is significantly matter of concern. Interactions between various ocean-atmosphere coupled modes occur through Rossby wave activity, westerly airflow, cyclone circulation changes the rain-bearing system during southwest monsoon season. This session focuses on how the multi-scale Land-Ocean-Atmosphere interaction affect the monsoon dynamics. Moreover, emphasis is placed on the role of these interactions on the monsoon extremes. We welcome studies using field measurements, remote sensing observations, theory and modelling to analyse this interplay for better understanding of the monsoon processes.

Description: The Indian Ocean, though the smallest of the three major oceanic basins, presents a striking diversity of oceanographic processes. At its northern extremity lies one of the most productive oceanic basins, as well as one of the world’s three principal denitrification zones, contributing nearly one-third of the global marine nitrogen loss. In contrast, the Central Indian Ocean hosts a vast oligotrophic gyre, with its southern portion encompassing a High Nutrient Low Chlorophyll (HNLC) region. The basin’s complex circulation systems, including the Somalia, Agulhas, Java-Sumatra, Equatorial, and West Australian currents, along with its prominent ridge systems and immense riverine inputs, strongly influence the cycling of carbon, nitrogen, and other essential elements. These interactions govern ocean productivity, ecosystem health, and regional climate variability. Given that ~30% of the global population depends on the Indian Ocean for livelihood, the basin’s health is under stress due to intensifying anthropogenic activities. Both natural variability and human-induced stressors modulate the biogeochemical processes, altering elemental cycling and ecosystem functioning. This session aims to examine our present understanding of the interactions between physical, chemical, and biological processes in the Indian Ocean. It will recommend a core program centered on observations and modeling to fill the gaps identified during the last two National Science Workshops on Indian Ocean Biogeochemistry.

Description: "Marine pollution is a critical environmental challenge with significant ecological, economic, and societal implications. India, with over 7,500 km of coastline and strategic positioning along the Indian Ocean, is particularly vulnerable to multiple forms of pollution. Microplastics from urban and industrial sources, heavy metals from riverine and estuarine discharge, hydrocarbon contamination due to oil spills and shipping activities, and emerging pollutants via groundwater inputs, and persistent organic pollutants (POPs) such as PCBs, pesticides, and pharmaceuticals are all contributing to the degradation of marine ecosystems. In the Indian context, these pollutants not only impact biodiversity and fisheries but also threaten food security, coastal livelihoods, and national initiatives such as the Blue Economy Mission. Considering India’s role as a regional leader in ocean science, a dedicated sub-theme addressing marine pollution is crucial to strengthen knowledge exchange, scientific collaborations, and policy integration.

Description: "Marine pollution is among the greatest threats to ocean health and the vital ecosystem services it supports. From microplastics and other emerging contaminants to nutrient enrichment, oil spills, heavy metals, and microbial pollution, a wide range of stressors threaten aquatic and marine ecosystems. These pollutants interfere with food-web dynamics, alter water quality, and disrupt key biogeochemical processes. Their impacts cascade from microbial communities to higher trophic levels, leading to biodiversity loss, habitat degradation, and ecosystem instability. In turn, they jeopardize fisheries, coastal livelihoods, and human health, while weakening the ocean’s resilience to climate change. This session will explore the scientific basis of how pollution alters ecosystem functions, from microbial processes to large-scale carbon and nutrient fluxes, and assess the socio-economic costs of degraded services. It will convene researchers, policymakers, and practitioners to examine the sources, pathways, and impacts of marine and estuarine pollution on key services such as carbon sequestration, nutrient cycling, food provision, and coastal protection. Drawing on case studies from regional seas, including the Indian Ocean, the session will highlight emerging challenges such as microplastics, emerging contaminants, heavy metal contamination, deoxygenation, harmful algal blooms, and microbial pollution in estuarine ecosystems. The overarching aim is to foster cross-disciplinary dialogue and advance innovative monitoring, mitigation, and policy strategies to safeguard ocean health and sustain essential ecosystem services "

Description: Mangroves, seagrasses, and salt marshes are known worldwide to be exceptionally effective in the sequestration of atmospheric carbon, thus contributes to mitigate climate change. Seagrasses and salt marshes contribute additional carbon stocks, albeit to a lesser extent. Although they are ecologically and climatically important, there is an uneven distribution of investigations into their carbon dynamics in India. Moreover, seagrass meadows and salt marshes are largely unevaluated. Significant obstacles to accurate carbon stock estimation include spatial heterogeneity, methodological variability and the effects of anthropogenic disturbances. The suggestions are to hold sessions on the development of methodological frameworks, improved blue carbon mapping and monitoring, and the possibilities of conserving the coastal ecosystem. It promotes focus on interdisciplinary methods to connect remote sensing, field studies, and policy frameworks to upscale blue carbon accounting and management. The purpose of this session is to develop cooperation among the researchers and policymakers to harness the services of coastal ecosystems to develop sustainable climate resilience.

Description: Ocean acidification and warming are two major consequences of global climate change. The rising sea surface temperature is altering species’ physiological performance, reproductive cycles, and distribution patterns. Simultaneously, the absorption of excess atmospheric CO₂ is decreasing oceanic pH, impairing calcification processes in corals, molluscs, echinoderms, and planktonic organisms, with cascading effects on trophic structure and biodiversity. This session will explore the impact of these anthropogenically induced stressors on the ecology and biology of tropical marine organisms. We will also dive deep into exploring empirical observations and advanced modelling strategies to predict the impacts, from coastal ecosystems to pelagic zones. We invite contributions from various stakeholders, including researchers, marine enthusiasts, citizen scientists, corporates, and policy makers, to discuss multi-scale and cross-ecosystem assessments, engage in collaborative discussions aimed at identifying future research possibilities, potential solutions and innovative strategies for tropical marine biodiversity conservation.

Description: "Abstract Heavy metal contamination in coastal marine sediments is a growing environmental concern due to its ecological impact and potential risk to human health. The present study investigates the concentrations, spatial distribution, and pollution status of heavy metals (Fe, Mn, Cr, Cu, Ni, Zn, and Pb) in surface sediments collected from the industrialized Tuticorin coast, Gulf of Mannar, southeast India. Sediment parameters such as calcium carbonate (CaCO₃) and organic matter (OM) were analyzed to understand depositional environments and pollution sources. The CaCO₃ content ranged from 35.74% to 89.04%, and OM ranged from 0.11% to 0.63%, indicating biogenic input and moderate terrestrial influence. To evaluate contamination levels, multiple geochemical indices were employed including Enrichment Factor (EF), Geoaccumulation Index (Igeo), Contamination Factor (CF), Modified Contamination Degree (mCd), Pollution Load Index (PLI), and Potential Ecological Risk Index (PERI). Results revealed very high contamination by Cu, Pb, and Cr with EF values >10 and CF values exceeding 13. The Igeo values confirmed extreme contamination, especially for Fe and Mn, suggesting strong anthropogenic influence. The PERI values ranged from 127.95 to 231.91, indicating moderate to high ecological risk, while PLI values >1 in selected stations affirmed localized pollution hotspots, likely due to untreated industrial discharges and fluvial transport from nearby rivers. Correlation matrix analysis showed strong associations between heavy metals (e.g., Cr–Cu) and fine sediments, highlighting the role of grain size and Fe–Mn oxides in metal adsorption. Overall, the study emphasizes the urgent need for effective environmental monitoring and pollution control strategies in the Tuticorin coastal zone."

Description: Oceans are facing multiple stressor problems due to ongoing climate change, such as ocean warming, deoxygenation, acidification and nutrient limitation. Ocean acidification is known for affecting marine organisms, especially the calcareous ones. The ongoing climate change can be mitigated if the excess CO2 is removed from the atmosphere. During the last few decades, ocean-based CO2 removal techniques have gained attention; therefore, various marine carbon dioxide removal (CDR) technologies are being tried to get effective CO2 sequestration, such as ocean alkalinity enhancement, artificial upwelling of nutrient-rich waters, ocean fertilisation, and seaweed cultivation. However, these technologies do come with negative consequences, and also, questions remain regarding their efficiency and scalability.

Description: This session aims to bring together researchers working on internal waves using satellite measurements, mooring and ship-based observations and numerical model simulations. Internal waves are baroclinic motions generated by wind and tidal forcing in a stratified ocean, with frequencies ranging from the local Coriolis frequency to the buoyancy frequency. Within this broad internal-wave band, two dominant types are internal tides—generated by tidal flow interacting with topography—and near-inertial waves, which are primarily generated by tropical cyclones and strong wind events in inertial frequency. Internal waves play a critical role in driving vertical mixing, which influences biological productivity, sediment transport, acoustic propagation, etc. Also, the vertical mixing driven by internal waves modulates large-scale circulation variability. This session invites discussions on major internal-wave generation hotspots in the Indian Ocean, the mechanisms governing their generation, propagation, and dissipation, their interactions with lower-frequency oceanic processes, and their implications for diverse physical and applied oceanographic studies.

Description: The coasts have been centres of human activity for ages be it recreation, for food or for commerce. As human population increased the coasts bore the brunt of overexploitation. In order to protect the fragile ecosystem, promote sustainable development, and ensure the well-being of coastal communities the Coastal Regulation Zone (CRZ) notification was issued in February 1991 for the first time. Later the regulations were revised periodically and will continue to do so. This session welcomes studies done along the coastal stretches of India as well as within the eco-sensitive areas in the CRZ, to gain a better understanding of the coast, which may help the policy makers in formulation of better CRZ policies. Case studies on developmental activities within the CRZ and their effects on the coastal ecosystem are welcome. We also look forward to studies carried out along the coasts of the world, and their regulatory framework.

Description: With constant longitudinal increase in coastal population and urbanization accelerating at an unprecedented rate, Indian urban coasts face a dangerous convergence of climate-driven risks such as sea-level rise, intensified storm surges, and recurrent flooding and these risks are profoundly amplified by unique and complex socio-economic stressors. Conventional methodologies for assessing coastal vulnerability, such as the widely used Coastal Vulnerability Index (CVI), have proven valuable for regional-scale physical risk assessment but are increasingly insufficient for capturing the multi-dimensional, hyperlocal, and deeply stratified vulnerability of dense urban systems. These established models often oversimplify the human dimension, failing to account for the critical role of informal economies, infrastructure fragility, and deep-seated social inequalities that characterize Indian urban coasts. This session will convene interested stakeholders to critically evaluate and move beyond these limitations. The focus will be on exploring next-generation integrated assessment frameworks that couple advanced geospatial technologies, including high-resolution remote sensing, GIS, and Artificial Intelligence/Machine Learning (AI/ML), with granular socioeconomic, demographic, and econometric data. By addressing these critical knowledge gaps, the session aims to contribute a new, more holistic understanding of urban coastal vulnerability, directly contributing to the goals of building resilient cities (SDG 11), protecting marine ecosystems (SDG 14), and enhancing the adaptive capacity of the most at-risk populations.
