The Bay of Bengal exposes abundant photosynthetic picoplankton and newfound diversity along salinity-driven gradients
(John Wiley & Sons, Ltd, 2023)
The Bay of Bengal (BoB) is a 2,600,000 km2 expanse in the Indian Ocean upon which many humans rely. However, the primary producers underpinning food chains here remain poorly characterized. We examined phytoplankton abundance ...
Isotopic composition of carbon and nitrogen of particulate organic matter in the Godavari estuary: Seasonality in sources and processes
(Springer, 2024)
Rivers transport organic matter originating within the estuary and terrestrial sources to the coastal ocean. The seasonal variations in the magnitude of river discharge alter the sources of particulate organic matter (POM) ...
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) ...
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 ...
An integrated buoy-satellite based coastal water quality nowcasting system: India�s pioneering efforts towards addressing UN ocean decade challenges
(Elsevier, 2024)
The Indian coastal waters are stressed due to a multitude of factors, such as the discharge of industrial effluents, urbanization (municipal sewage), agricultural runoff, and river discharge. The coastal waters along the ...
Spatial variability in nitrogen uptake rates and f-ratio in the northern Indian Ocean
(Elsevier, 2024)
Inorganic nitrogen is the major limiting nutrient in the northern Indian Ocean. The published and unpublished data of nitrate (NO3?) and ammonium (NH4+) uptake rates and estimated f-ratios (new to total production) for the ...
Global subterranean estuaries modify groundwater nutrient loading to the ocean
(John Wiley & Sons, Ltd, 2024)
Terrestrial groundwater travels through subterranean estuaries before reaching the sea. Groundwater-derived nutrients drive coastal water quality, primary production, and eutrophication. We determined how dissolved inorganic ...
Major sources of sinking particulate organic matter in the western Bay of Bengal
(Elsevier, 2024)
Impacts of river discharge on coastal ocean processes are multi-dimensional. Studies on sinking particle fluxes, composition and their seasonal variability in coastal oceans are very limited. In this study, we investigated ...
Response of coastal phytoplankton to pollution from various sources in the coastal Bay of Bengal
(Springer, 2024)
The coastal ocean receives nutrient pollutants from various sources, such as aerosols, municipal sewage, industrial effluents and groundwater discharge, with variable concentrations and stoichiometric ratios. The objective ...
Global oceanic diazotroph database version 2 and elevated estimate of global oceanic N2 fixation
(Copernicus Publications, 2023)
Marine diazotrophs convert dinitrogen (N2) gas into bioavailable nitrogen (N), supporting life in the global ocean. In 2012, the first version of the global oceanic diazotroph database (version 1) was published. Here, we ...
