The need to reduce anthropogenic nutrient inputs to aquatic ecosystems in order to protect drinking-water supplies and to reduce eutrophication, including the proliferation of harmful algal blooms...
Chesapeake Bay eutrophication: scientific understanding, ecosystem restoration and challenges for agriculture.
Coastal eutrophication and agriculture:contributions and solutions.
Cultural eutrophication, the pollution of coastal waters by nutrients, is a result of population growth, food production (agriculture, animal operations and aquaculture), and energy production and con...
Human activities, especially increased nutrient loads that set in motion a cascading chain of events related to eutrophication, accelerate development of hypoxia (lower oxygen concentration) in many a...
We used paleolimnological data for 240 lakes from the U.S. Environmental Protection Agency’s (USEPA) 2007 National Lakes Assessment to estimate the extent that natural lakes in the coterminous United...
Using large-scale field surveys across 12 estuaries in two provinces in Atlantic Canada, we analyzed changes in phytoplankton and benthic macroalgal communities as well as the canopy structure of eelg...
Atmospheric deposition of nutrients (N and P species) can intensify anthropogenic eutrophication of coastal waters. It was found that the atmospheric wet and dry depositions of nutrients was remarkabl...
We explored multiyear linear trends in nutrient concentrations, nitrogen (N) : phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake ...
Using 31-yr data from measurements in a lake that has experienced change in eutrophication status, I showed that the effects of global warming on chlorophyll a (Chl a)–normalized maximum rates of phot...
Sedimentary records of organic matter inputs (stable nitrogen isotopes [d15N], nitrogen [N], and carbon [C] content), phytoplankton abundance (pigments, stable carbon isotopes [d13C]), and community c...
The accumulation of anthropogenic CO2in the ocean has altered carbonate chemistry in surface waters since preindustrial times and is expected to continue to do so in the coming centuries. Changes in c...
In the years 1970-1977 eutrophication models have been developed and applied for about 15 shallow Danish lakes. The structure of these models are discussed. An example of the calibration of the mode...
Under certain conditions, sediment cores from coastal settings subject to hypoxia can yield records of environmental changes over time scales ranging from decades to millennia, sometimes with a resolu...
The Integrated Catchments model of Phosphorus dynamics (INCA-P) was applied to the River Lugg to determine the key factors controlling delivery of phosphorus to the main channel and to quantify the re...
