Microbial keystone players and biogeochemical impacts of Noctiluca scintillans bloom in Mandovi estuary on west coast of India
(Elsevier, 2025)A sporadic outbreak of the bioluminescent dinoflagellate Noctiluca scintillans (NS) occurred in the Mandovi estuary along the Goa coast of the Central Eastern Arabian Sea on 24th May 2023, prompted by pre-monsoon upwelling, ... -
Anthropogenic stressors of black clam distribution in Kochi backwaters on the Indian west coast
(Springer, 2025)The black clam (Villorita cyprinoides Gray, 1825) is the most commercially important clam in India and the major share of its landing (around 25,000 tonnes/year) comes from Kochi backwaters (KBW), the largest estuarine ... -
Seasonal dynamics and environmental drivers of productivity in the Cochin Estuarine System: Insights from estuarine turbidity maxima
(Elsevier, 2025)The Cochin estuarine system, characterised by its Estuarine Turbidity Maximum (ETM) zones, undergoes significant seasonal variations influenced by riverine input and tidal forces. This study examined the seasonal shifts ... -
Dinoflagellate cyst and nannofossil imprints in the middle Eocene Kirthar transgressive strata from the western Garo Hills, South Shillong Plateau, India
(Elsevier, 2025)One of the global characteristic features of the Eocene is the extensive development of carbonate platforms in various regions of Tethys. Paleogene sequences of the Shillong Plateau from west to east are exposed in the ... -
Diapycnal oxygen flux in the oxycline region of the core of the Arabian Sea Oxygen Minimum Zone
(Elsevier, 2025)This study quantified the relative contributions of double diffusion and shear-driven mixing on the diapycnal oxygen flux in the oxycline region of the core of the Arabian Sea Oxygen Minimum Zone (OMZ), a critical oceanic ... -
Bacterial communities and their functional profiles from mangroves, a blue carbon ecosystem and terrestrial forest habitats
(Springer, 2025)Microorganisms play a crucial role in the biogeochemical cycling of organic matter through their heterotrophic activity. This study delves into comparing the sediment bacterial communities from the mangrove habitats of ... -
Fatty acid and sterol biomarkers as indicators of symbiont activity in chemosynthetic organisms from a methane seep ecosystem (Krishna-Godavari basin, Bay of Bengal)
(Springer, 2025)In the present study, an attempt was made to characterize the bacterial symbionts present in the organisms, their carbon sources and assess tissue-specific isotope variability within the organisms in Bathymodiolus, ... -
Source, bioavailability, and toxicity of metals in modern fjord sediments, west Spitsbergen, and their influence on sediment-associated biota
(FRONTIERS MEDIA SA, 2024)Metal contamination in the Arctic region has increased over the years despite its remote and isolated location. Thus, to evaluate the bioavailable fractions of various metals and their effects on sediment-associated biota, ... -
Evaluation of fate of organic matter in sediment through microcosm experiments
(Wiley Online Library, 2024)Laboratory microcosm experiments help to understand the degradation pattern of different sources derived from organic matter (OM) at the sediment?water interface and relate it to field processes. Microcosm experiments were ... -
Variations in wind wave parameters measured in the coastal waters of north-eastern Bay of Bengal
Characteristics of the wind waves measured in the coastal waters of the northeastern Bay of Bengal are examined for 4 years. A comparison of the energy wave period (Te) with different wave periods shows that the average ... -
First record of a cold-seep squat lobster Munidopsis lauensis Baba and de Saint Laurent, 1992 (Anomura: Galatheoidea) from Indian waters
(Brazilian Crustacean Society, 2025)The present study reports the first zoogeographical record of the squat lobster Munidopsis lauensis Baba and de Saint Laurent, 1992 from a cold-seep site in the Krishna-Godavari Basin (Bay of Bengal), Northern Indian Ocean. ... -
Seabed videography using indigenously built deep sea underwater camera
(Current Science, 2024)In the recent years, underwater visual survey is becoming as a powerful investigation technique, especially in focus to deep-sea study. In this paper, we report seabed investigation made with an easy-to-operate indigenously ... -
Crustal recycling and mantle heterogeneity beneath the Central Indian ridge, Indian Ocean,
(Elsevier, 2025)This study presents a new database including mineral chemistry, whole rock geochemistry and Sr-Nd isotopic compositions for basalts recovered from the Central Indian Ridge (CIR) with a view to evaluate melt generation ... -
The water budget of the Mahadayi river and its implications for the inter-state dispute
(Springer, 2024)We assess the water budget of the Mahadayi river, an inter-state basin on India's west coast with a long-running dispute. We seek to answer the following question: What is the discharge at any given location along the ... -
Disruptive synergism: The Co-occurrence of scyphozoan Pelagia noctiluca (Forssk l, 1775) swarms with green tide-causing dinoflagellate Noctiluca scintillans (Macartney) Kofoid & Swezy, 1921,
(Elsevier, 2025)The swarming behavior of certain scyphozoan clades, such as Pelagia noctiluca (Forsk l, 1775), highlights an evolutionary advantage. These adaptations promote survival and reproductive success, resulting in mass occurrences. ... -
Spatial and temporal variations in net primary production and long-term trends between 2003 and 2022 in the Indian Ocean: A synthesis using different models
(Elsevier, 2025)The measurements of net particulate primary production (NPP) with reference to space and time are limited in the Indian Ocean. Therefore, models are the only source of understanding spatial, temporal, and long-term variations. ... -
Sedimentary organic matter signature hints at the phytoplankton-driven biological carbon pump in the central Arabian Sea
(COPERNICUS GESELLSCHAFT MBH, 2025)The central Arabian Sea, a unique tropical basin, is profoundly impacted by monsoon wind reversal affecting its surface circulation and biogeochemistry. Phytoplankton blooms associated with high biological productivity and ... -
