Eutrophication in the Krka estuary

Marine Chemistry, 1994
Changes in longitudinal distribution of eutrophication parameters in brackish and marine layers of a stratified karstic estuary have been investigated from December 1988 until October 1989 on a gradient between a pristine and a moderately polluted area. In the estuary, only marine phytoplankton blooms were found to develop. Near the head of the estuary,

The Economics of Eutrophication

2013
This chapter focuses on how economists deal with nonpoint source pollution where individual farm field emissions are not observed. This causes problems for the standard emissions marginal abatement cost framework used in environmental economics as it renders emission-oriented policy instruments not applicable. Still, this framework is useful as it sets

Eutrophication and Zoobenthos dynamics

Ophelia, 1995
The possible effects of eutrophication on benthic dynamics are discussed based on the Pearson-Rosenberg Model that describes the effects of organic enrichment on qualitative characteristics of benthic communities. Depending on the amount of organic matter reaching the sediments, the model describes three successive states: a) slight increases in ...

The Irish Sea: Is it eutrophic?

Estuarine, Coastal and Shelf Science, 2008
The question of whether the Irish Sea is eutrophic is addressed by reviewing the evidence for anthropogenic nutrient enrichment, elevated phytoplankton production and biomass and undesirable disturbance in the context of the EU and OSPAR definitions of eutrophication.

Eutrophication control in the Netherlands

Hydrobiologia, 1999
Due to the limited perspectives of the Dutch national policy and due to the unique conditions and constraints of individual lake systems, tailor-made programs are needed for the restoration of freshwater lakes. Based on an evaluation of several restoration projects, a guideline is provided to enable water managers to develop such a restoration program.

Effects of Eutrophication

2013
Eutrophication as one of the importunate environmental hazards in the aquatic ecosystems causes pronounced deterioration of the water quality and represents serious threat to the biotic components of this ecosystem. The main environmental effects of eutrophication are increase of suspended particles owing to extensive macroalgal blooms, decrease of ...

Eutrophication of Microponds

Journal of Environmental Quality, 1975
AbstractThree soils having different chemical and physical properties were flooded with deionized water and used as bottom soils for greenhouse microponds. The submerged soils supplied sufficient nutrients to the overlying waters to sustain algal growth for 489 days in two successive floodings of 219 and 270 days each.Differences in electrical ...
