Table 7. Signatures for between region differences in epidemic parameters within 2002.

Location	Change in Number of Dead	Change in DOE	Change in PMD	Change in Prevalence
Wadden Sea NL vs Tay	−ve	+ve	+ve	Unknown
Limfjord vs Baltic (option 1)	−ve	+ve	+ve	Unknown
Limfjord vs Baltic (option 2)	NS	+ve	+ve	Unknown
Wash vs Moray Firth	−ve	+ve	+ve	NS

+ve = positive change, −ve = negative change, NS = no significant change.

The direction of change is for the second region relative to the first. Two possible signatures have been included for Limfjord versus the Baltic region because the difference in the number of dead seals relative to population size was marginal.
