Hypoxia is a harmful result of anthropogenic climate change. With the expansion of global
low-oxygen zones (LOZs), many organisms have faced unprecedented challenges affecting …

Dissolved oxygen (DO) concentration is an essential index for water environment
assessment. Here, we present a modeling approach to estimate DO concentrations using …

Estuaries are action zones for organic carbon (OC) degradation and aging. These
processes influence the nature of terrestrial OC (OCterr) export and the magnitude of OCterr …

Human activities and climate change have changed large river estuary ecosystems, which
impacts nutrient enrichment in coastal waters. Enhanced nutrient levels lead to …

Coastal ecosystems serve as important nursery areas, yet they are facing many challenges.
For example, eutrophication-induced hypoxia is one of the major threats to the functioning of …

Ciénaga Grande de Santa Marta lagoon complex, located in the Colombian Caribbean, is a
highly degraded estuarine system, in which massive deaths of organisms have occurred …

We investigated the bio-and photo-lability of dissolved organic matter (DOM) from the head,
mixing zone, and mouth of the Pearl River estuary. At all three sites, bio-and photo-refractory …

Dissolved oxygen (DO) concentration in estuaries is highly variable at different spatial and
temporal scales, which is affected by physical, chemical and biological processes. This …

The coastal waters around the Yangma Island are an important mariculture area of raft-
raised scallop and bottom-seeded sea cucumber in the North Yellow Sea, China. Large …

Nitrogen (N) mineralization and immobilization are two important N transformation
processes in estuarine sediments. However, the biotic and abiotic mechanisms regulating …
