From: Waterline responses to climate forcing along the North American West Coast
a Map of the North American West Coast, the monitored coastline is shown in light yellow. Dashed boxes delineate the different subregions of the study area. Pie charts show the regional distribution of advancing/retreating waterline trends during 2000–2022 derived from the dataset presented in this study. b–e Time series of monthly averaged significant wave height (Hs, red) and sea level anomaly (SLA, blue) at Long Beach, WA, Monterey, CA, Torrey Pines, CA and Playa el Suspiro, Baja California Sur (from top to bottom) between 2000–2020, with wave data from ERA5 dataset (ECMWF, 2020101) and sea-level provided by NOAA102,103,104 tide gages (replaced by AVISO (CNES, 2020105) data at Playa el Suspiro). Black circles (blue squares) on (a) indicate locations of the four sites (closest ERA5 wave model nodes) described on the right panels. The lateral boundaries of the rectangles delineating the subregions are intended solely to visually illustrate the extent of each subregion and should not be interpreted as representing the offshore or nearshore limits of the coastal system. We use the ESRI World Imagery layer as the background map.
