Discovery of fossil micrometeorites from the Deccan trap intertrappeans
(Wiley Online Library, 2024)Abstract The Cretaceous?Paleogene (K-Pg) boundary represents the extinction of ~70% of species, a prominent Chicxulub impact event and Deccan volcanism. This work reports the first attempt to extract the micrometeorites ... -
Tracing marine and terrestrial biochemical signatures of particulate organic matter in an Arctic fjord (Kongsfjorden)
(Elsevier, 2024)Arctic fjords are hotspot for organic matter (OM) transformation and storage, however, the composition and sources of the particulate organic matter (POM) are still not completely understood. Further, due to the ongoing ... -
A Northgrippian sedimentary magnetic enhancement along the western margin of India
(Elsevier, 2024)Sedimentary magnetic records of shelf region contains complex environmental evolution information, necessitating records from various global regions to accurately interpret its significance. A sediment core (SSD-39/GC-01) ... -
Assessment of Benthic Meiofauna in Multi-Stressed Environment of a Tropical Estuary: a Case Study Using Low Taxonomic Resolution Data
(Springer, 2024)The estuary receives varying anthropogenic inputs that significantly influence the benthic biota and suppress ecological health. Thus, multiple parameters (natural and anthropogenic) and meiofaunal community structures ... -
Seasonal shift in trophic status induced by bacterial metabolic activity in tropical mangrove-dominated estuaries of Southwest India
(Springer, 2024)Mangroves are highly productive ecosystems that supply carbon and nutrients to the coastal food web from autochthonous and allochthonous sources. The fluctuations in the quantity of these sources influence bacterial metabolic ... -
Biogeochemical cycling of iodine in the Bay of Bengal: A comparison with the Arabian Sea
(Elsevier, 2024)Iodine is a redox-sensitive element and a potential oxidant for the respiration of organic matter. Here we report the spatial variation of dissolved iodine in the Bay of Bengal (BoB) oxygen minimum zone (OMZ) and compare ... -
Seasonal nutrient loadings in four monsoonal micro/meso tidal tropical estuaries, west coast of India,
(Elsevier, 2024)Nutrient concentrations were studied seasonally along estuarine and fluvial regions of four micro/meso tidal rivers from Karnataka and Maharashtra, west coast of India. This study was performed to assess the pathway of ... -
Preparation and Characterization of Agar Polysaccharide from Red Alga Phycocalidia Vietnamensis (Bangiales)
(Springer, 2024)In this research, biomass of the red algae Phycocalidia vietnamensis (Bangiales) was investigated for agar production. Agar was prepared by the hot water extraction method with 0, 4, 6, 8, 10% (w/v) NaOH pre-treatments. ... -
Macrobenthic communities in the polymetallic nodule field, Indian Ocean, based on multicore and box core analysis
(FRONTIERS MEDIA SA, 2024)Managing deep-sea mining is challenging due to limited data on species and habitat distribution, hindering decision-making. In less-explored polymetallic nodule sites in the Indian Ocean, management approaches are deemed ... -
Evaluation of the proximate composition and antioxidant capacity of some seaweeds from the Konkan coast of India
(Elsevier, 2024)Minerals, antioxidants, and other nutrients that promote health can be found in abundance in seaweeds. In this study, we evaluated the proximate composition and antioxidant capacity of some seaweeds from Konkan coast of ... -
Delineating morphological traits of oceanic micro-phytoplankton as potential ecological indicators
(Elsevier, 2024)The micro-phytoplankton (>20 ?m) adaptations and resilience were assessed using morphological traits (shape, surface-to-volume ratio; S:V, and greatest-axial-linear-dimension; GALD) from sea-surface and different SCML-depths ... -
Production of marine-derived bioactive peptide molecules for industrial applications: A reverse engineering approach
(Elsevier, 2024)This review examines a wide range of marine microbial-derived bioactive peptide molecules, emphasizing the significance of reverse engineering in their production. The discussion encompasses the advancements in Marine ... -
Bomb-radiocarbon in the Northern Indian Ocean
(Elsevier, 2024)Bomb-radiocarbon is a useful tracer to study ocean circulation and air-sea CO2 exchange processes. In the present study bomb radiocarbon distribution in dissolved inorganic carbon of the Northern Indian Ocean around late ... -
Indian Ocean Acidification and Its Driving Mechanisms Over the Last Four Decades (1980 2019)
(Wiley Online Library, 2024)Abstract This paper aims to study the changes in the Indian Ocean seawater pH in response to the changes in sea-surface temperature, sea-surface salinity, dissolved inorganic carbon (DIC), and total alkalinity (ALK) over ... -
Impact of river discharge and suspended sediments on the nearshore benthic environment along the Indian southwest coast
(Elsevier, 2024)River discharge into the sea and its implications on the environmental setting and fauna in the nearshore represent the intricate interactions among the atmosphere, hydrosphere, lithosphere, and biosphere. This study, based ... -
Polychlorinated biphenyls in the surface and deep waters of the Southern Indian Ocean and Coastal Antarctica
(Elsevier, 2024)Polychlorinated biphenyl compounds (PCBs) are industrial chemicals whose production was discontinued in the early nineties in most countries. Sill, PCBs are detectable in pristine and remote locations. Occurrence in regions ... -
Feasibility of Hydrate-Based Carbon dioxide Sequestration in Arabian Sea Sediments
(Elsevier, 2024)Carbon capture and sequestration (CCS) is the key option to achieve the global net-zero emission targets. In this direction, gas hydrate-based CO2 sequestration in subsea sediments has gained significant attention due to ... -
