Conditions that favour frequent occurrence of
C. quinquecirrha medusae in Chesapeake Bay are salinities
of 10–16 and temperatures of 26–30°C in summer
(Brown et al., 2002). The preponderance of
medusae within those ranges led to development of
a model that permits near-real-time prediction
(nowcasting) of medusa occurrence (http://coastwatch.
