Bars show trends in latitude (a), longitude (b), and depth (c) computed from observed occurrence locations versus year (1950–2015) for each species. Mean climate velocities (d,e) and trends in bottom water temperature (f) and onset dates for spawning temperatures 8 to 14 oC (g-j) computed from model hindcast at occurrence locations versus year (1958–2012). Vertical line (f) indicates mean warming trend in temperature record. Trends included only if significant at α = 0.05. Symbols indicate taxon (blue circles, bivalves; cyan squares, gastropods; purple diamonds, polychaetes; green triangles, echinoderms); legend indicates species. Lon, longitude; Lat, latitude.
