This image is a cropped rendition of  two aerial images that demonstrate satellite-derived cyanobacteria concentrations in surface waters from an area in Florida.

A three year study was conducted in seasonal wetlands to determine if a deep and shallow water pool resulted in a reduction of methylmercury in caged fish and surface water.

Graphical depiction of a seasonal wetland engineered to have a deeper pool and more open water on the downstream side of the wetland. This management strategy was tested during a 3-year period to determine if it resulted in a reduction of methylmercury in caged fish and surface water.

Map of the study region showing the location of lakes in (A) Florida and (B) Ohio. In total, 135 lakes in Florida and 21 lakes in Ohio, were resolvable with the full resolution MERIS data and are used in this study. Land and lakes are shown in gray and blue colors respectively.

This photo show runoff from an experimental plot through a weir.  Scientists carried out the study at the Oklahoma State University South Central Research Station in Chickasha, Oklahoma. Its a good example of rain induced runoff. 

Graphical depiction of three sources of variation that can affect accumulation of methylmercury in black rails: habitat (sediment) biogeochemistry, food web structure and biomagnification, and diet composition. Methylmercury moves from the sediment into the wetland food web and accumulates in rail tissues.

Biplot of principal component analysis of soil elemental composition data. Background and enriched samples are denoted. Colored points are from potentially enriched soils at mine sites, and black points are from unmined background sites. The effect of different elements on the analysis is shown by the rays, which are labeled to identify the elements.
