Long-term changes in Nutrient Concentration and Fluxes from the Godavari Estuary: Role of River Discharge and Fertilizer Inputs
(Springer, 2023)The discharge from the Indian peninsular rivers is strongly controlled by the intensity of monsoonal rainfall, which is strongly influenced by atmospheric extreme events, such as El Niño, La Niña, and Indian Ocean Dipole ... -
Impact of ocean warming on net primary production in the northern Indian Ocean: role of aerosols and freshening of surface ocean
(Springer, 2023)Warming due to climate change stratifies the upper ocean and reduces nutrient input to the photic zone resulting in a decline in net primary production (NPP). On the other hand, climate change increases both anthropogenic ... -
Recurrence of Gonyaulax polygramma bloom in the southeastern Arabian Sea
(Springer, 2023)Gonyaulax polygramma, a bloom-forming dinoflagellate, has been repeatedly observed along the southeastern Arabian Sea in recent years. During our study in October 2021, a patch of reddish-brown water was observed in the ... -
Persistent increase in carbon burial in the Gulf of Mannar, during the Meghalayan Age: Influence of primary productivity and better preservation
(Cambridge University Press, 2023)The oceans store a substantial fraction of carbon as calcium carbonate (CaCO3) and organic carbon (Corg) and constitute a significant component of the global carbon cycle. The Corg and CaCO3 flux depends on productivity ... -
Preliminary observations on the coral reef communities in Angria Bank, an isolated carbonate bank in the Northern Indian Ocean
(Elsevier, 2023)Submerged carbonate banks are of significant geological and biological importance and relatively little is known about the biodiversity of these deeper and less accessible habitats. This study provides pilot information ... -
Folin-Ciocalteu assay as a rapid colourimetric screening method for evaluating PAH degradation abilities of heterotrophic bacteria
(Springer, 2023)Bioremediation using microbes is an eco-friendly approach being explored for reclaiming PAH-contaminated areas. However, isolation and screening of potential bacteria to degrade PAHs are very laborious and cumbersome. To ... -
Standardization of micro-FTIR methods and applicability for the detection and identification of microplastics in environmental matrices
(Elsevier, 2023)The ubiquity of microplastics (MPs) in the various environment is of increasing concern. Although micro Fourier Transform Infrared Spectroscopy (μ-FTIR) represents an ideal method for the detection of MPs, this technique ... -
Air-Sea Fluxes of CO2 in the Indian Ocean Between 1985 and 2018: A Synthesis Based on Observation-Based Surface CO2, Hindcast and Atmospheric Inversion Models
(Wiley-AGU, 2023)The Indian Ocean significantly influences the global carbon cycle but it is one of the undersampled regions with reference to surface ocean pCO2. As a part of the Regional Carbon Cycle Assessment and Processes-2 (RECCAP2) ... -
Role of physical processes in regulating the biological responses in the Eastern Arabian Sea during the late southwest monsoon
(Elsevier, 2023)Understanding physical properties and associated biological responses in the marine ecosystem is critical for fisheries and assessing the ocean’s role in determining the fate of anthropogenic carbon dioxide emissions. This ... -
Coastal vegetation and estuaries are collectively a greenhouse gas sink
(Springer Nature, 2023)Coastal ecosystems release or absorb carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), but the net effects of these ecosystems on the radiative balance remain unknown. We compiled a dataset of observations from ... -
SAtellite-based Marine Process Understanding, Development, Research and Applications for Blue Economy (SAMUDRA): A Technology Demonstration Program in the Bay of Bengal
(Springer, 2023)SAtellite-based Marine Process Understanding, Development, Research and Applications (SAMUDRA) for blue economy, a technology development program of the Space Applications Centre, is an umbrella program covering research ... -
Winter phytoplankton size classes in the Northeastern Arabian Sea based on in-situ and remote sensing methods
(Elsevier, 2023)Phytoplankton size classes (PSCs) are important in marine ecosystems because they organise the food chain and trophic pathways, which determine the overall biological environment. Based on three FORV Sagar Sampada cruises, ... -
Recent advancements in coral health, microbiome interactions and climate change
(Elsevier, 2023)Corals are the visible indicators of the disasters induced by global climate change and anthropogenic activities and have become a highly vulnerable ecosystem on the verge of extinction. Multiple stressors could act ... -
Impact of the Upper Ocean Processes on Intensification of Cyclone Amphan
(Springer, 2023)Cyclone Amphan is one of the severe cyclones that occurred over the Bay of Bengal region. It has undergone rapid intensification over the northern part, i.e., north of 14� N after its formation. This can be attributed to ... -
Revisiting the Biostratigraphic Range and Possible Cause of the First and Last Occurrence of Globigerinoides Ruber (Pink) in the Northern Indian Ocean
(The Cushman Foundation for Foraminiferal Research, Kansas, USA, 2023)The first and last occurrence datums of species are often used as biostratigraphic markers to establish chronology beyond the range of radiocarbon dating. One such datum, the last occurrence of Globigerinoides ruber (pink) ... -
Malformation in coccolithophores in low pH waters: evidences from the eastern Arabian Sea
(Springer, 2023)Oceanic calcifying plankton such as coccolithophores is expected to exhibit sensitivity to climate change stressors such as warming and acidification. Observational studies on coccolithophore communities along with carbonate ... -
Anthropogenic impact and antibiotic resistance among the indicator and pathogenic bacteria from several industrial and sewage discharge points along the coast from Pydibhimavaram to Tuni, East Coast of India
(Springer, 2023)Increasing urbanisation and industrialisation of the Visakhapatnam region have brought domestic sewage and industrial wastewater discharge into the coastal ocean. This study examines the indicator and pathogenic bacteria�s ... -
Acquisition of natural remanence in the basaltic laterites of Deccan volcanic province (India): Implications to palaeomagnetic studies in laterites
(Elsevier, 2023)Lateritization in the Deccan basalt province (India) represents a large spectrum of chemical weathering with up to 99% CIA values and complete ferri- to antiferromagnetic transformations. We combined rock magnetic, ... -
Multi-resource potentiality and multi-hazard susceptibility assessments of the central west coast of India applying machine learning and geospatial techniques
(Springer, 2023)The understating of natural resources and hazards is very fundamental from spatial perspective to reduce loss of resource and human lives. For this, the main aim of the current research is to synthesize the three natural ... -
