dc.description.abstract A computer file of all published distributional data (presence or absence) on the living and dead recent benthic foraminifera off the North American Pacific Coast (Oregon to Alaska) was constructed from 31 papers published since 1886. Manipulation of this file produced 5 catalogs and 139 maps. Catalog 1 lists alphabetically species names with publication and locality information as recorded in the literature (i.e., unsynonymized). Catalog 2 lists synonymized species names with publication and locality information. Catalogs 3 and 4 list alphabetically all unsynonymized and synonymized species names, respectively. Catalog 5 lists synonymized names by increasing latitude and longitude. During the past 100 years, 523 names have been used to record benthic foraminifera in the study area. Through synonymization, this number was reduced to 404, of which 138 occur at 6 or more of the 157 sample localities. Computer-generated maps were drawn for the 138 most commonly recorded species. Species were grouped by depth and geographic (latitudinal) distribution through visual examination of the maps. Eight species are coastal in their distribution, 63 occur mainly at depths of less than 200 m, 27 at depths greater than 200 m, and 40 are ubiquitous with depth. Many species appear to alter their depth distribution with latitude, but this may be due to a poor sampling framework. Latitudinally, the species are grouped into three categories. Forty-two species occur mainly to the north of 52°-55°N, 22 species occur mainly to the south of 52°-55°N, and 74 species are latitudinally ubiquitous within the area of study. This preliminary analysis indicates a possible faunal break in the region of Queen Charlotte Island. en_US
