Sea Nettle Probability of Encounters

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

Chrysaora quinquecirrha is white and occurs most abundantly in the tributaries of the middle Bay, where salinities range from 10 to 20 parts per thousand (ppt). In the southern Bay, it often has red/maroon markings on the long central tentacles and on the swimming bell. C. quinquecirrha occurs from Cape Cod south along the U.S. East Coast, Caribbean, and Gulf of Mexico; it abounds in the Chesapeake Bay in numbers unequaled elsewhere.

The maps are experimental and depict the probability of encountering sea nettles (jellyfish) in the Chesapeake Bay and its tributaries. They are generated for the Chesapeake Bay Office of NOAA's Fisheries Service by the National Centers for Environmental Prediction and the National Ocean Service. These maps are numerical model guidance only; they are not fully validated and may not reflect actual conditions. Additional sea nettle information, including the method to calculate encounter rate of sea nettles in the Bay, is available from the NOAA Chesapeake Bay Office sea nettle forecasting web site. Contact NOAA with any comments or inquiries.
