Overview map of the study area on the Olympic Peninsula in Washington State, USA, and locations and names of 17 dive sites (black dots) and 27 towed video transects (red lines) and their associated transect numbers.
Five grouping “areas” (Crescent Bay, Freshwater Bay, Elwha Bluffs, Ediz Hook, Dungeness Bluffs) used in the analysis of towed video data are shown in red in panel ‘a’, and four site-groups (Control, East, Mouth, West) used in the analysis of dive site data are shown in black in panels ‘a’ and ‘b’. Abbreviations in parentheses for areas and site-groups are used in tables and figures. The locations of the two former dam sites are shown in panel ‘c’ with white stars. NOAA water level station 9444090 is shown in panel ‘a’, and NOAA wave buoy 46088 is shown in panel ‘c’, both marked with black stars. Ten meter contour lines in panels ‘a’ and ‘b’ are derived from pre-dam removal bathymetry [52–55]. In panel ‘c’, SJDF = Strait of Juan de Fuca.
