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 ... -
Performance of ERA5 winds on computed storm surge and wave-current interaction using a coupled model during Ockhi cyclone
(Springer, 2023)A fully coupled numerical model was setup to simulate tides as well as storm surges and waves generated by the very severe cyclonic storm Ockhi, which occurred in the Arabian Sea during 29 November-6 December 2017. ERA5 ... -
Variability in phytoplankton shape dominance in marine pelagic systems: prevalence of different adaptive strategies in the eastern Arabian Sea during the winter monsoon
(Springer, 2023)Phytoplankton communities from pelagic systems were assessed to explore the potential of using commonly used traits (such as cell geometry and taxa) as ecological function indicators from the data generated during the ... -
Role of aerosol liquid water content on the production of dicarboxylic acids in the dust-laden air masses over the Arabian Sea: Implications for heterogeneous chemistry
(Elsevier, 2023)Oxalic acid and the related organics are ubiquitous water-soluble constituents of ambient organic aerosols (OA). Their molecular distributions and relative abundances provide crucial insights on the secondary OA formation ... -
Flood-associated hydrobiological changes in the nearshore off Kochi, along the southwest coast of India
(Elsevier, 2023)This study presents how flood water transforms the hydrobiology of the nearshore waters close to estuarine inlets along the southwest coast of India, which are susceptible to significant freshwater discharge during the ... -
Applications of Machine Learning in Chemical and Biological Oceanography
(American Chemical Society, 2023)Machine learning (ML) refers to computer algorithms that predict a meaningful output or categorize complex systems based on a large amount of data. ML is applied in various areas including natural science, engineering, ... -
A 50 kyr record of eolian sedimentation in the Eastern Arabian Sea - Dust deposition changes synchronous with the Northern Hemisphere Climatic Oscillations
(Elsevier, 2023)The Late Pleistocene Northern Hemisphere (NH) climate was extremely variable, owing to the abrupt warm Dansgaard-Oeschger (D/O) events and cold Heinrich events in the Greenland and North Atlantic. Although the close coupling ... -
Phytoplankton community structure in the Kandla port ecosystem situated in a creek in the Gulf of Kutch, India
(Springer, 2023)The port ecosystems are prone to deterioration due to the maritime and coastal activities and as a major source of the country�s economy need efficient management. Phytoplankton communities can serve as reliable indicators ... -
