Tracing terrestrial versus marine sources of dissolved organic carbon in the largest monsoonal Godavari estuary in India using stable carbon isotopes
(Elsevier, 2022)
To examine the sources of dissolved organic carbon (DOC) and its modifications within the estuary, time-series sampling was conducted at 10 stations covering the entire salinity range in the Godavari estuary.The salinity ...
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) ...
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 ...
Isotopic evidence of denitrified nitrate in groundwater beneath intensive agriculture and exchange with estuary (Godavari, India)
(American Chemical Society, 2024)
Nitrate is accumulated in the groundwater, modified through nitrification/denitrification, and exchanged with coastal/estuarine water bodies. To examine the sources and modifications of nitrate, the concentrations and ...
Dissolved organic carbon (DOC) and labile organic compounds spatial and temporal variations in coastal Indian groundwater: Their bioavailability and transfer to neighboring coastal waters of India
(Springer, 2024)
Submarine groundwater drainage (SGD) changes the elemental composition of the neighboring coastal ocean and impacts the biogeochemical cycles. To examine the seasonal and spatial variability in dissolved organic carbon ...
