Details: This article explores the growing threat of coastal pollution along India’s shorelines, emphasizing its ecological, social, and economic impacts. It highlights key sources such as industrial discharge, sewage inflow, plastic debris, and agricultural runoff, which collectively degrade water quality and harm marine biodiversity. Using case studies and recent research, including the role of microbial indicators and satellite-based monitoring, the piece illustrates how integrated scientific approaches are essential to assess and manage coastal pollution. The article also advocates for community engagement and policy interventions to ensure the sustainability of India’s coastal ecosystems.

Factors responsible for the sudden outburst of Noctiluca scintillans in the Chennai coastal waters, southeast coast of India- A case study. Oceanologia (Inpress), (2022). https://doi.org/10.1016/j.oceano.2022.06.005

Details: This study investigates the environmental and anthropogenic factors leading to the sudden bloom of Noctiluca scintillans (a bioluminescent dinoflagellate) along the Chennai coast, southeast India. The study highlights how nutrient enrichment from land-based sources, elevated sea surface temperatures, and altered coastal circulation patterns contributed to the proliferation of this species. It examines in situ observations and satellite data to assess the ecological impact, including reduced dissolved oxygen and potential harm to local fisheries. The findings underscore the importance of monitoring coastal eutrophication and climate-induced oceanographic changes in managing harmful algal blooms.

Details: This study explores the spatial distribution and seasonal dynamics of phytoplankton communities in the hypersaline environment of Pulicat Lagoon, a critical coastal wetland on India’s southeast coast. Through systematic sampling across monsoon and dry seasons, the research reveals how salinity gradients, nutrient fluctuations, and temperature shifts influence phytoplankton composition and abundance. Dominant taxa, including diatoms and cyanobacteria, exhibit clear seasonal preferences, with higher diversity observed during post-monsoon periods. The findings highlight the lagoon’s ecological sensitivity and provide baseline data essential for assessing the impacts of climate change and anthropogenic pressures on coastal lagoon ecosystems.

Details: This study employs environmental DNA (eDNA) techniques to assess bacterial diversity and community composition in ecologically sensitive sites exposed to high anthropogenic activity. By analyzing water and sediment samples from impacted coastal and urban regions, the research reveals shifts in microbial assemblages linked to pollution, nutrient enrichment, and human disturbance. High-throughput sequencing of eDNA provides insights into the presence of both beneficial and potentially pathogenic taxa, highlighting microbial indicators of ecosystem health. The findings underscore the utility of eDNA as a non-invasive, high-resolution tool for monitoring microbial biodiversity and informing sustainable environmental management.
