(A). Algal bloom magnitude in Florida lakes in 2011 before normalization and (B) after normalization by lake surface area. Area-normalized magnitude (km⁻²) of selected lakes provided as part of bar labels in parenthesis.

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.

The cyanobacteria Gleotrichia shown under a microscope from a water sample collected at Ek Lake Trail, a popular recreational area in Kabetogama Lake where algal blooms frequently occur. Gleotrichia  can produce microcystin.

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.
