Linking Land Use, Seasonal Variation and Water Quality Through Dissolved Organic Matter Optical Properties in the Doce River Basin

Ecohydrology, Volume 18, Issue 7, October‐November 2025.
ABSTRACT Human activities such as agriculture, mining and urbanization have profoundly altered tropical river systems, yet conventional water quality indicators often fail to fully capture these impacts, especially in turbid waters. In the Doce River Basin, Southeast Brazil, the characterization of dissolved organic matter (DOM) through its optical ...

Mesoscale and submesoscale variability of organic matter in island-induced eddies across their life cycle: implications for the biological carbon pump

Frontiers in Marine Science
The Canary Islands region exhibits intense mesoscale activity, with eddies generated south the islands by perturbations of the Canary Current. After detachment, these eddies drift southwestward along the Canary Eddy Corridor (CEC), exporting their ...

Clarifying the trophic state concept to advance macroscale freshwater science and management

Ecosphere, Volume 16, Issue 9, September 2025.
Abstract For over a century, ecologists have used the concept of trophic state (TS) to characterize an aquatic ecosystem's biological productivity. However, multiple TS classification schemes, each relying on a variety of measurable parameters as proxies for productivity, have emerged to meet use‐specific needs.

Absorption features of chromophoric dissolved organic matter (CDOM) and tracing implication for dissolved organic carbon (DOC) in Changjiang Estuary, China

, 2013
Abstract. Chromophoric dissolved organic matter (CDOM) represents the light absorbing fraction of dissolved organic carbon (DOC). Studies have shown that the optical properties of CDOM can be used to infer the distribution and diffusion characteristics of DOC in the estuary and coastal zone.
