Dominant contribution of atmospheric nonlinearities to ENSO asymmetry and extreme El Nino events
(Nature Publishing Group, 2024)Extreme El Nino events have outsized impacts and strongly contribute to the El Nino Southern Oscillation (ENSO) warm/cold phase asymmetries. There is currently no consensus on the respective importance of oceanic and ... -
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 ... -
Atmospheric deposition of mineral dust and associated nutrients over the Equatorial Indian Ocean
(Elsevier, 2024)Aerosols are potential supplier of nutrients to the surface water of oceans and can impact biogeochemical processes particularly in the remote locations. The nutrient data from atmospheric supply is poorly reported from ... -
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 ... -
Linking genetic lineages of giant freshwater prawn Macrobrachium rosenbergii to their global populations
(Springer, 2024)Globally, the giant freshwater prawn Macrobrachium rosenbergii is considered as a commercially important aquaculture species. Genetically, this species is differentiated into western, central and eastern populations. ... -
Fungal diversity associated with Goa�s tarballs: Insights from ITS region amplicon sequencing
(Elsevier, 2024)This study explores the fungal diversity associated with tarballs, weathered crude oil deposits, on Goa�s tourist beaches. Despite tarball pollution being a longstanding issue in Goa state in India, comprehensive studies ... -
Impact of COVID-19 lockdown on methane related activities in a tropical estuarine mangrove ecosystem
(Springer, 2024)The COVID-19 pandemic led to an immediate lockdown declared by the government of India (March to April 2020) which saw a decrease in public activities. In view of this, a comparative study was carried out on the influence ... -
A 70 kyr record of monsoon-induced marine productivity changes, terrigenous flux and weathering variations in the southern Bay of Bengal
(Geological Society of India - GeoScienceWorld, 2024)The southwest (SW) and northeast (NE) monsoon winds significantly affect the oceanographic and climatic changes over the Bay of Bengal (BoB). We present here detailed geochemical and isotopic records from two sediment cores ... -
