Tidally-modulated high frequency internal waves in Gautami-Godavari estuary, East coast of India
(CSIR-NISCAIR, 2014)
Time series temperature and salinity (at 1 hour interval) and currents data (10 min interval) at surface (3 m) and bottom (14 m), collected in the Gautami-Godavari estuary during 25-27 September 2008 were utilized to ...
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 ...
Assessing seasonal nitrogen transformations in the Godavari estuary, India
(Elsevier, 2023)
Indian estuaries are hypothesized to export a significant amount of nitrogen nutrients to the coastal waters due to the high use of fertilizers. To examine the possible sources of nitrogen nutrients and their modifications ...
Enhanced Atmospheric Pollutants Strengthened Winter Convective Mixing and Phytoplankton Blooms in the Northern Arabian Sea
(Wiley, 2022)
The recent increase in atmospheric pollutants (aerosols) over the northern Indian Ocean due to an increase in industrial activity in South and Southeast Asia decreased air temperature (AT) leading to the strengthening of ...
Impact of atmospheric anthropogenic nitrogen on new production in the northern Indian Ocean: Constrained based on satellite aerosol optical depth and particulate nitrogen levels
(The Royal Society of Chemistry, 2022)
Aerosols are one of the significant external sources of soluble reactive nitrogen to the surface ocean and their deposition affects the primary productivity.Owing to rapid industrialization over South and Southeast Asia, ...
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) ...
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 The published and unpublished data of nitrate (NO3?)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 ...
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 ...
Rapid shoaling of aragonite saturation horizon in the northern Indian Ocean
(IOP Publishing, 2024)
Anthropogenic carbon dioxide (CO 2 ) penetrates up to 1000 m of water column in the Indian Ocean resulting in acidification and corrosion of aragonite skeletal material. The shallowest aragonite saturation horizon (ASH) ...
A new climatology of depth of nitracline in the Bay of Bengal for improving model simulations
(John Wiley & Sons, Ltd, 2024)
The dissolved nitrate is one of the major essential nutrients for primary production in the tropical ocean and it is brought to the surface though mixing. The depth of nitracline determines how much of nitrate enters to ...
