Sources and dynamics of sedimentary organic matter in Sundarban mangrove estuary from Indo-Gangetic delta

Introduction: Mangrove forests are highly productive ecosystems distributed along the tropical coast line. Nutrient biogeochemistry of mangroves are primarly driven by both allochthonous and autochthonous sources. Characterization of organic matter in coastal ecosystems enables to understand the biogeochemical transformation of organic matter and its influence on ecosystem productivity in respo...

Source characterization of dissolved organic matter in a subtropical mangrove-dominated estuary by fluorescence analysis

Measurements of dissolved organic carbon (DOC), UV–visible, fixed wavelength fluorescence, and synchronous fluorescence were performed in an effort to characterize spatial and temporal variability in concentration and source of dissolved organic matter (DOM) in surface waters of the southwest coast of Florida. Concentrations of DOC in the surface water ranged from 318 to 2043 AM and decreased f...

Early diagenesis of plant-derived dissolved organic matter along a wetland, mangrove, estuary ecotone

We studied the role of photochemical and microbial processes in contributing to the transformation of dissolved organic matter (DOM) derived from various plants that dominate the Florida Everglades. Plant-derived DOM leachate samples were exposed to photochemical and microbial degradation and the optical, chemical, and molecular weight characteristics measured over time. Optical parameters such...

Indo-Gangetic river systems, monsoon and malaria.

The history of the Indo-Gangetic river systems from the late nineteenth to the early twentieth centuries can be reconstructed from the meticulous official records of the survey, meteorological and medical departments of the British Government of India. In contrast with the grand sweep of the geological evidence, these records indicate a complex narrative of floods, droughts and channel shifts. ...
