The overall objective is to measure quantitatively the spatial and temporal patterns of coastal invasions. We propose to establish a national baseline of data that measure invasion attributes by location (including geographic region or latitude), taxonomic group, source region, vector, and date of arrival. Our specific objectives are: * To establish a standardized, quantitative baseline of survey data for all coasts of North America; * To make available extensive geographically-referenced data from the surveys, through expansion of our online information system (NEMESIS), which includes detailed information for ~400 non-native marine species; * To test for differences in the extent of invasions among coasts and by latitude; * To test for a correlation among bays in the number of invasions with (a) the number of ship arrivals, as well as other measures of vector activity, among bays and (b) environmental and biological characteristics of the bays.
