Sea Nettles Probability of Encounters (Experimental)

The jellyfish often encountered in the Chesapeake Bay in the summer is the sea nettle Chrysaora chesapeakei. Knowing where and when to expect this biotic nuisance may help to alleviate an unpleasant encounter.

These maps are experimental and depict the probability of encountering sea nettles (not their abundance or density) in the Chesapeake Bay area. The density of sea nettles that you may encounter is not reflected here because it can vary greatly from year to year at a given location and would be a much less reliable prediction.
