Dynamics of subsurface chlorophyll maxima in the northern Indian Ocean
(Elsevier, 2024)Subsurface chlorophyll maxima (SCM) significantly contributes to oceanic primary productivity, emphasizing the need to study its dynamics and governing mechanisms. We used datasets from various platforms to investigate ... -
Allelochemicals from the seaweeds and their bioprospecting potential
(Springer, 2024)Allelochemicals are secondary metabolites which function as a natural protection against grazing activities by algae and higher plants. They are one of the major metabolites engaged in the interactions of organisms. The ... -
Recent advancements in marine micropaleontological and paleoceanographic research from India
(Springer, 2024)The article presents an overview of the research contributions in the field of Marine Micropaleontology and Paleoceanography, made by the Indian scientists during the last five years. Keeping pace with recent development ... -
Gigantidas niobengalensis sp. nov. (Bivalvia: Mytiloidea) from a methane seep in the Krishna-Godavari Basin, Bay of Bengal
(Conchological Society of Great Britain and Ireland, 2024)A new species of a deep-sea Bathymodiolinae mussel is described as Gigantidas niobengalensis sp. nov. based on both molecular and morphological data. It was collected at a cold methane seep environment in the Bay of Bengal ... -
Effect of spiciness on the intensification of cyclones over Arabian Sea - A case study on Biparjoy
(Springer, 2024)In recent decades, there has been notable variability in the occurrence, frequency, and intensification of cyclones worldwide, and a significant trend has emerged in the northern Indian Ocean, notably the Arabian Sea. The ... -
Fresh and recirculated submarine groundwater discharge zones along the central west coast of India
(Elsevier, 2024)The study area receives an average of 2840.0 mm of rainfall within four months every year. A portion of the rainwater is flown to the sea as surface water, and the other part is percolated into the bottom as groundwater. ... -
Exploring the hidden treasures: Deep-sea bacterial community structure in the Bay of Bengal and their metabolic profile
(Frontiers Media, 2023)Deep sea bacterial communities demonstrate remarkable adaptability to high-pressure environments coupled with low temperatures which has sparked curiosity about their diversity and exceptional metabolic pathways. Additionally, ... -
Characterization of phytoplankton functional types in the western Bay of Bengal: HPLC- and CHEMTAX-based approach
(Springer, 2024)This study investigates phytoplankton functional group variations in the western Bay of Bengal (WBoB) during the Spring Intermonsoon. Samples were collected from four cross-shore transects: Mahanadi (MN), Vamsadhara (VD), ... -
Intrusion of Arabian Sea high salinity water and monsoon-associated processes modulate planktic foraminiferal abundance and carbon burial in the southwestern Bay of Bengal
(Springer, 2024)The unicellular calcareous planktic foraminifera sequester a significant portion of the carbon dioxide dissolved in the ocean, thus burying the carbon in sediments for millions of years. The global warming and associated ... -
Seasonally varying biogeochemical regime around the coral habitats off central west coast of India
(Elsevier, 2024)The Western Indian Continental Shelf (WICS) experiences upwelling during the Southwest Monsoon (SWM), leading to deoxygenation and acidification of subsurface waters. The region has patchy growth of corals, e.g. in the ... -
Extremely oligotrophic and complex-carbon-degrading microaerobic bacteria from Arabian Sea oxygen minimum zone sediments
(Springer, 2024)Sediments underlying marine hypoxic zones are huge sinks of unreacted complex organic matter, where despite acute O2 limitation, obligately aerobic bacteria thrive, and steady depletion of organic carbon takes place within ... -
Biodegradation of Low Density Polyethylene (LDPE) using marine bacteria isolated from tropical beaches of megacity Mumbai
(CSIR-National Institute of Science Communication and Policy Research (NIScPR), New Delhi, 2023)Plastics, although as useful and versatile as they are, have led to major environmental pollution. Its resistance to degradation has caused a major global threat to the environment. Plastic waste is disposed of in landfills ... -
An insight into the prokaryotic diversity from a polymetallic nodule-rich region in the Central Indian Ocean Basin using next generation sequencing approach
(Frontiers Media, 2024)Deep sea is a vast, dark, and difficult-to-access terrain and is now looked upon as a unique niche harboring diverse microorganism. We used a metataxonomic approach to decipher the microbial diversity present in the water ... -
A comprehensive assessment of macro and microplastics from rivers Ganga and Yamuna: Unveiling the seasonal, spatial and risk factors
(Elsevier, 2024)There have been growing apprehensions and concerns regarding the increasing presence of plastic pollutants in the holiest river of India, the Ganga, and its major tributary, Yamuna. In response to this issue, the current ... -
Chemical compositions of Fe-rich relict olivines from cosmic spherules, understanding their links with ordinary and carbonaceous chondrites
(John Wiley & Sons, Ltd, 2024)Fe-rich relict olivine grains are found in a small percentage of cosmic spherules, which are studied here to determine the nature of their precursors. We examined 128 Fe-rich relict olivine grains with Fa >10 mol% from 53 ... -
