Soil organic carbon storages and bacterial communities

1. Introduction. Mangrove ecosystems located along tropical and subtropical coastlines provide many ecological services [1, 2].Mangroves are one of the most productive and efficient long-term natural carbon (C) sinks [3, 4] and as such have been identified along with seagrasses and saltmarshes as key blue carbon ecosystems [5, …

Particulate Organic Carbon Transport From the Himalaya to the Ganga

The erosion of the Himalaya generates the world largest influx of sediments to the oceans. Carried by the Ganga-Brahmaputra fluvial system, 1 to 2 billions tons of sediments are discharged to the Bay of Bengal every year. While the particulate organic carbon (POC) concentration is relatively low between 0.6 and 1 % (Saffiulah et al., 1985) this translates …

There has been considerable debate on how atmospheric deposition (AD) in the watershed alters the supply of dissolved organic carbon (DOC) to river and coastal ecosystems. Here we show how AD-N and –P in the Ganga River Basin (GRB) drives the delivery of DOC. We conducted three sets of studies, a 3 year (2016–2018) in situ trial, a …

The uptake of atmospheric CO2 and the cycle of dissolved inorganic carbon (DIC) in the ocean are the major mechanisms and pathways controlling global climate change and carbon cycling. The stable carbon isotope (δ13C) of DIC, therefore, provides an important tracer for processes such as air-sea exchange, photosynthesis, and water …
