nutrient transport Gulf Mexico
2020/9/18
The Gulf of Mexico receives considerable levels of nutrients from the rivers that empty into it, especially the Mississippi River, causing the Gulf's northern waters to become overly enriched and more...
Algae-killing viruses spur nutrient recycling in oceans（图）
Algae-killing viruses nutrient recycling oceans
2019/10/23
Scientists have confirmed that viruses can kill marine algae called diatoms, but diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae.Diatoms ar...

Episodic vertical nutrient fluxes nearshore phytoplankton blooms Southern California
2014/4/2
Three distinct phytoplankton blooms lasting 4–9 d were observed in approximately 15-m water depth near Huntington Beach, California, between June and October of 2006. Each bloom was preceded by a vert...

Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
An investigation of submarine groundwater–borne nutrient fluxes to the west Florida shelf and recurrent harmful algal blooms
An investigation submarine groundwater–borne nutrient fluxes the west Florida shelf recurrent harmful algal blooms
2014/4/4
A cross-shelf, water-column mass balance of radon-222 (222Rn) provided estimates of submarine groundwater discharge (SGD), which were then used to quantify benthic nutrient fluxes. Surface water and g...
