Methane gas flares in the forearc basin of the Andaman-Nicobar subduction zone
(Frontiers Media SA, 2024)Gas hydrates deposits in the Andaman forearc basin are inferred from seismic data and confirmed by drilling/coring during the NGHP-01 expedition. We present new evidence of gas flares in the Andaman forearc basin, detected ... -
Report of epibiont ciliates (Ciliophora) found on meiofauna from Mumbai and adjacent coastal areas of India
(Station Biologique de Roscoff Institute, Roscoff, France, 2024)The article describes nine suctorian epibiont ciliates, viz. Limnoricus ceter Jankowski, 1981, Thecacineta calix (Schr�der, 1907), Thecacineta sp., Thecacineta urceolata Liao & Dovgal, 2015, Lecanophrya truncata (Collin, ... -
Rapid shoaling of aragonite saturation horizon in the northern Indian Ocean
(IOP Publishing, 2024)Anthropogenic carbon dioxide (CO 2 ) penetrates up to 1000 m of water column in the Indian Ocean resulting in acidification and corrosion of aragonite skeletal material. The shallowest aragonite saturation horizon (ASH) ... -
Seasonal dynamics of mangrove outwelling and its impact on estuarine productivity: insights from multi-parameter analysis across tidal variations
(Springer, 2024)Tropical mangroves are subjected to extreme environmental conditions yet remain highly productive ecosystems. The Mandovi and Zuari estuaries of Goa on the western coast of India are lined by mangroves and are a rich source ... -
Intercomparison of tropical Indian Ocean circulation in ocean reanalysis and evaluation in CMIP6 climate models
(Elsevier, 2024)In the present study, we assess the Tropical Indian Ocean (TIO) circulation features from the available ocean reanalysis products and the latest version of Coupled Model Intercomparison Project (CMIP6) climate model ... -
Spatiotemporal variation of microbial communities in surficial sediments of Cochin estuary, southwest coast of India
(Springer, 2023)Microorganisms play a major role in the degradation of organic matter in sediments. However, the spatiotemporal variation and factors affecting these communities are not clearly understood. At the same time, conventional ... -
Characterization of the molecular differential responses in marine benthic macroinvertebrates exposed to polycyclic aromatic hydrocarbons
(Springer, 2024)Polycyclic aromatic hydrocarbons (PAHs) are organic chemicals that can induce oxidative stress, genotoxicity, immunotoxicity, endocrine disruption, and developmental toxicity and are carcinogenic. Marine benthic ... -
Outcrop analogue constraints on subsurface reservoir properties of the Puga geothermal field, NW Himalaya
(Elsevier, 2024)The Puga valley, in Ladakh, contains one of India�s most prospective geothermal systems. Substantial geophysical and geochemical research has been conducted to characterise this system, though uncertainties regarding the ... -
Extraction of persistent lagrangian coherent structures for the pollutant transport prediction in the Bay of Bengal
(Nature Publishing Group, 2024)Lagrangian Coherent Structures (LCS) are the hidden fluid flow skeletons that provide meaningful information about the Lagrangian circulation. In this study, we computed the monthly climatological LCSs (cLCS) maps utilizing ... -
Winds and waves in the Arabian Gulf: Physics, characteristics and long-term hindcast
(John Wiley & Sons, Ltd, 2023)A 40-year hindcast of the wave conditions in the Arabian Gulf, the elongated basin between the Arabian Peninsula and Iran, is described. The input wind fields were derived from the ERA5 reanalysis by the European Centre ... -
Differential food utilization of benthic amphipods of a tropical estuary: A stable isotopic (?13C and ?15N) investigation
(Springer, 2024)Globally, stable isotopic methods are rapidly being employed in food web studies to quantify the relative proportions of diverse primary carbon sources in an animal diet. Tropical estuarine ecosystems, one of the vital ... -
Comparing environmental impacts of deep-seabed and land-based mining: A defensible framework
(John Wiley & Sons, Ltd, 2024)The crises of climate change and biodiversity loss are interlinked and must be addressed jointly. A proposed solution for reducing reliance on fossil fuels, and thus mitigating climate change, is the transition from ... -
Effects of seasons and successive upwelling phases on phytoplankton size classes in the Southeast Arabian Sea
(Elsevier, 2024)The responses of Phytoplankton Size Classes (PSCs) to seasons and the distinct phases of coastal upwelling in the northern Indian Ocean is an understudied aspect. This study introduces observations from a monthly time ... -
Resource utilisation and trophic niche overlap of coralline intertidal benthic amphipods: an isotopic perspective
(Springer, 2024)Benthic amphipod feeding groups are a well-established trophic classification that is mostly based on field observations and laboratory tests and are used in ecological studies to monitor the ecological state of benthic ... -
Relationship between dietary fiber content and prebiotic potential of polysaccharides from the seaweeds of the North west coast of India
(Elsevier, 2024)The macroalgae are a sustainable bioresource that can be harnessed for their functional food and nutraceutical applications. This study characterized the biochemical composition and bioactive potential of natural biological ... -
Distribution and bioaccumulation status of polycyclic aromatic hydrocarbons (PAHs) in Veraval coastal waters using copepods as bio-indicators
(Springer, 2024)The study investigates the pollution characteristics of 16 priority PAHs, accumulated in copepods from a major fishing harbour and its adjacent coastal waters of Veraval, west coast of India. The total PAH accumulation is ... -
Response of inner shelf benthic foraminiferal community to different concentrations of dissolved oxygen under laboratory culture experiment
(SAGE Publications, New Delhi, India, 2024)Dissolved oxygen, a vital parameter for a majority of marine organisms, may decline in the near future due to anthropogenic eutrophication in coastal waters. The effect of depleting dissolved oxygen on the marine benthic ... -
