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 ... -
Recent trends on bioremediation of heavy metals; an insight with reference to the potential of marine microbes
(Springer, 2024)Heavy metals are essential for the survival of all living organisms in trace amounts. Industrializations and urbanisation are the two major rationale behind the massive rise in the contamination of land and water bodies ... -
Assessment of metal-associated health risk in different trophic levels in tropical estuary on the southeast coast of India
(Elsevier, 2024)Metal contamination in coastal and marine ecosystems has become a significant global concern due to its hazardous characteristics, environmental persistence, and ability to bioaccumulate in aquatic ecosystems. This poses ... -
Influence of cadmium and zinc contamination on the sediment microbiome of estuarine and coastal ecosystems in the Southwest Coast of India
(Springer, 2024)Metals and their nanoparticles can induce toxicities that influence the survival of both microorganisms and macroorganisms. The current study reports on the impact of heavy metal pollution on the microbiome of estuarine ... -
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 ... -
Role of Nitrifiers Associated with Mangrove clam Polymesoda Erosa in Bioremediation
(Springer, 2024)Polymesoda erosa is a mangrove clam known for its water filtration ability. This clam was investigated for its bioremediation potential and growth in synthetic wastewater during 40 days of incubation. Variation in the ... -
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 ... -
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 ... -
Biofilm-forming bacteria associated with corals secrete melanin with UV-absorption properties
(Springer, 2024)Corals are colonized by a plethora of microorganisms, and their diversity plays a significant role in the health and resilience of corals when they face oxidative stress leading to bleaching. In the current study, we ... -
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 ... -
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 ... -
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 ... -
Influence of the extreme Indian Ocean dipole 2019 on the equatorial Indian Ocean circulation.
(Springer, 2024)This study examines direct current measurements in the central equatorial Indian Ocean during the positive phase of the extreme Indian Ocean Dipole (pIOD) in 2019. Analysis of near-surface zonal current at 77E and 83E ... -
Impact of the Pacific-Japan pattern on the tropical Indo-western Pacific Ocean surface waves
(Springer, 2024)The present study examines the impact of the Pacific-Japan (PJ) pattern on tropical Indo Western Pacific Ocean significant wave heights during the boreal summer season (June through August, JJA) for the first time. The PJ ... -
Distribution and sea-to-air fluxes of nitrous oxide and methane from a seasonally hypoxic coastal zone in the southeastern Arabian Sea
(Elsevier, 2024)The seasonal variability, pathways, and sea-to-air fluxes of nitrous oxide (N2O) and methane (CH4) in the coastal environment, where coastal upwelling and mudbanks co-exist are presented based on the monthly time-series ... -
Plankton diversity and dynamics in the upper surface of the Indian sector of the Southern Ocean ecosystem and biogeochemical processes
(Elsevier, 2023)In the Southern Ocean (SO) marine ecosystem, the interplay between CO2 sink and climate change is closely linked to the shifting plankton communities, leading to potentially wide-ranging biogeochemical effects. Within the ... -
Behaviour of barium in the tropical estuaries: Implications to its marine budgets and paleo-oceanographic applications
(Elsevier, 2023)Marine Barium (Ba) is extensively used as a tracer for biogeochemical processes and paleo-oceanographic proxy for past river discharge, salinity, and long-term hydrological changes. However, poor constrain on the riverine ... -
Petrogenesis of submarine volcanic arc rocks from Andaman subduction zone, Northeast Indian Ocean: Constraints from slab components and mantle wedge characteristics
(Elsevier, 2024)The present study provides new petrological and geochemical data of the dredged rocks from submarine volcanoes along the Andaman arc and describes the petrogenetic evolution of the arc system in terms of mantle wedge ... -
Shell size variation of pteropod Heliconoides inflatus: Inferences on Indian Ocean carbonate chemistry during late quaternary
(Springer, 2024)The current study is an effort to understand the relationship between the average shell size and Limacina Dissolution Index (LDX) of pteropod species, Heliconoides inflatus as a metric for shell calcification using several ...
