Their marine systems work in much the same way as they do on racing cars.
This excess loading of carbon, nitrogen, and phosphorus is leading to cultural eutrophication of marine systems.
In marine systems, spores of green algae and even some floating but fertile plants can traverse great distances.
Not only do freshwater aquatic systems undergo cultural eutrophication, but coastal marine systems also may be affected by this process.
For example, many lake, estuarine, and coastal marine systems receive too much nitrogen from atmospheric deposition and terrestrial runoff.
At Qingdao, in Shandong province east of Beijing, a research centre is being built for marine systems operating at great depths.
This question is virtually unstudied in marine systems.
Patchiness or spatial variability is ubiquitous in marine systems.
Nitrogen loss from landscapes affects downstream freshwater and marine systems.
The found levels were very low compared to other marine systems, below parts per million.
I worked in freshwater and marine systems all over Canada and studied a broad variety of animals.
