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...
Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: eutrophication modeling
biomass burning ocean water quality Southeast Asia atmospheric deposition eutrophication modeling
2010/12/20
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...
Nitrogen fixation may not balance the nitrogen pool in lakes over timescales relevant to eutrophication management
Nitrogen fixation may not balance nitrogen pool in lakes over timescales relevant eutrophication management
2014/4/17
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 ...
Evidence of warming effects on phytoplankton productivity rates and their dependence on eutrophication status
warming effects phytoplankton productivity rates eutrophication status
2014/4/17
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...
Carbonate chemistry in the coastal zone responds more strongly to eutrophication than to ocean acidification
Carbonate chemistry in the coastal zone responds more strongly eutrophication ocean acidification
2014/4/16
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...
