The Rising Influence of Rising Affluence

some of the toxic and noxious stuff produced by living and rotting algae are gases, eg dimethylsulfide. At shore, concentrations of aerosolized droplets and gaseous metabolites are higher and are diluted away from shoreline.

I’d also venture that even relatively flat water still has a lot of churning and splashing and that onshore winds can bring aerosolized droplets from many miles away from the shoreline.
