Spatial variations and controlling factors in phytoplankton composition at deep chlorophyll maxima in the Bay of Bengal
(Elsevier, 2025)
The occurrence of deep chlorophyll maxima (DCM) in the stratified oceanic regions is reported either due to photoacclimation or the availability of nutrients. The influence of mesoscale processes, such as eddies, on the ...
Long-Term Changes of Surface Total Alkalinity and Its Driving Mechanisms in the North Indian Ocean
(American Geophysical Union, 2025)
This study examines long-term changes in surface total alkalinity (TA) in the North Indian Ocean (NIO) by developing a machine learning-based data product (INCOIS_TA) using ship-based observations collected from different ...
Determining chlorophyll-a thresholds for characterizing algal bloom conditions: An ocean colour remote sensing approach
(Elsevier, 2025)
The Indian coast has been experiencing an increase in algal bloom events over the decades. Owing to the regional and seasonal dynamics of algal biomass (proxy: chlorophyll-a, hereafter chl-a), a multitude of thresholds of ...
Shift in the phytoplankton composition associated with reversal in east India coastal currents in the Bay of Bengal
(Elsevier, 2025)
The alteration of phytoplankton composition due to variations in physical mixing, salinity, nutrient concentrations and their stoichiometric ratios would impact the overall ecosystem, affect the food web and influence the ...
Tropical cyclones enhance net CO2 sink in the Bay of Bengal
(Elsevier, 2025)
Tropical cyclones modify the upper ocean due to significant mixing associated with increased winds that bring CO2 and nutrient-rich subsurface waters to the surface, altering CO2 flux and biological production. In the ...
Spatial and temporal variations in net primary production and long-term trends between 2003 and 2022 in the Indian Ocean: A synthesis using different models
(Elsevier, 2025)
The measurements of net particulate primary production (NPP) with reference to space and time are limited in the Indian Ocean. Therefore, models are the only source of understanding spatial, temporal, and long-term variations. ...
Disruptive synergism: The Co-occurrence of scyphozoan Pelagia noctiluca (Forssk l, 1775) swarms with green tide-causing dinoflagellate Noctiluca scintillans (Macartney) Kofoid & Swezy, 1921,
(Elsevier, 2025)
The swarming behavior of certain scyphozoan clades, such as Pelagia noctiluca (Forsk l, 1775), highlights an evolutionary advantage. These adaptations promote survival and reproductive success, resulting in mass occurrences. ...
