Sentences with phrase «with eutrophication»

The decline in pH affecting oysters in Chesapeake Bay (Waldbusser et al. 2011) was not attributable to anthropogenic CO2 but was likely attributable to excess respiration associated with eutrophication.

Not exact matches

1.6 %: estimated proportion of marine fish species (for which trend data exist) with increasing populations, due to improved conditions including better fishing management and decreased eutrophication

In a 37 - year experiment with a lake in northern Ontario, scientists demonstrated that controlling phosphorus in particular is the key to reversing eutrophication.

Over the past 50 years, changes in land use and wastewater inputs have led to eutrophication of the lake, with increased turbidity and oxygen depletion in deeper waters.

Ocean acidification, rising temperatures, eutrophication and loss of oxygen: Life in the oceans has to cope with a variety of factors.

The ammonia is washed away, creating a major environmental issue as it leads to eutrophication of water ways and ultimately enters the atmosphere as nitrogen dioxide, the main greenhouse gas associated with agriculture.

As with air pollution, evidence suggests that human - driven climate change will, on average, worsen eutrophication in freshwater and marine systems.

Eutrophication - The process by which a body of water (often shallow) becomes (either naturally or by pollution) rich in dissolved nutrients, with a seasonal deficiency in dissolved oxygen.

Oceanic pH is never constant and various continually in accordance with a host of environmental parameters, such as eutrophication, salinity and land - based - effluents, etc, and so you can not lay the blame on CO2 without first eliminating the possibility that a change in pH was not due to some other factor.

Similarly, a comparison of large reservoir locations (Lehner et al. 2011) with model - predicted dissolved inorganic phosphorus (DIP) yields (Harrison et al. 2010) indicates that most large reservoirs occur in phosphorus enriched regions (figure 4a) that may promote eutrophication of reservoirs.

«Scientist» seems to agree with Gavin on this, because, despite these ugly numbers, despite the graph that's level for centuries before going hyperbolic in the 20th Century, despite the obvious impossibility of meaningful calibration 1850 - 1995, despite the chapter - and - verse description in Tiljander03 of roadbuilding, peat cutting, farming, bridge reconstruction, and eutrophication — I used the word «absolutely.»

The effects of eutrophication on carbonate chemistry can exceed that of OA from anthropogenic CO2 by either increasing pH, when enhanced CO2 uptake by primary producers prevails (Borges and Gypens 2010), or by decreasing pH, where enhanced respiratory CO2 release prevails (Cai et al. 2011), a condition often associated with coastal hypoxia (Feely et al. 2010).

Although eutrophication is the major concern related to these inputs, the pH of coastal waters is also influenced through the enhanced CO2 uptake from primary production and CO2 release from respiration associated with increased nutrient inputs.

Discharge from sewage treatment plants and runoff from agricultural fields contaminate bodies of water with excess phosphorus, leading to eutrophication.

In addition, ocean acidification is co-occurring with other drivers of environmental change (including warming, eutrophication, hypoxia, eutrophication, pollution [12]-RRB-, yet the interactive effects and relative importance of multiple stressors on species physiology, life history and ecology, as well as species — environment interactions and ecosystem function remain poorly understood [13 — 17].

In the long run, the excess algal growth can have devastating impacts on the health and age of a fresh water lake or river, causing eutrophication to speed up, where lakes and other water bodies fill in with dead algae and other organic matter and eventually turn into dry land.
