Location of BeachX. Inset wave rose shows the location and distribution of offshore waves from ERA5. b The detailed map of BeachX (Curl Curl Beach, New South Wales, Australia). The color gradient at the seaside indicates bathymetry. Yellow lines represent transects. Red dots show the location of nearshore waves.

Six example sites around Oʻahu with forecasted vegetation line positions for the month of July, under 0.3–1.2 m (1 ft (black)—4 ft (yellow)) of SLR. Locations are labeled by number and common beach name, and oriented with North pointing upwards in every photo except for Kūʻau. Inset of Oʻahu has labels of approximate locations of the example sites.

BAYEX predictions of 100-year storm surge return levels and associated 90% credible interval widths for the entire US coastline. From the study Observations reveal changing coastal storm extremes around the United States.

Water flux through a tidal creek with a small, moderate, and extreme tide range during (A) a flood tide and (B) an ebb tide. Creek velocity legend applies to all tide ranges.

Map of study area: China Camp State Park and the adjacent shallows of San Pablo Bay. Black and gray bathymetry lines indicate the location of mean higher high water (MHHW) and mean lower low water (MLLW), respectively. Elevations in meters of those tidal datums are referenced to the North American Vertical Datum of 1988

Composites of hydrodynamic and morphological responses to (a–c) ENSO phases and (d–f) the strongest El Niño events during winter (DJF) over 1997–2022.

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.

Photos of (a) coastal wetland, (b) coral reef, (c) dryland, and (d) alpine ecosystems. These ecosystems are chronically exposed to high levels of abiotic stress that approach physiological tolerance limits.

Depiction of a horizontal levee (A) and study location in San Francisco Bay, CA(B and C). Transects used in the hydrodynamic simulations are shown by the white lines in (C).

Drift logs stranded by 1957 tsunami in Stardust Bay, Sedanka Island, Aleutian Islands, Alaska. From the study A 700-year rupture sequence of great eastern Aleutian earthquakes from tsunami modeling of stratigraphic records.

Figure: a Great earthquakes in the 20^th century. Inset numbers over the 3 by 12 grid indicate subfaults with large slip in meters from the updated 1957 rupture model³ with red and blue tones for shallow and deeper megathrust rupture, respectively.

Floodplain maps and bar graphs depicting the expansion of the 1% floodplain after earthquake-driven subsidence today (2023) and in 2100 when the earthquake-driven subsidence is amplified by climate-driven sea-level rise for the (A) Necanicum River, OR; (B) Yaquina Bay, OR; (C) Alsea Bay, OR; and (D) Humboldt Bay, CA.

Projected 21st-century land loss and organic carbon disturbance on Alaska’s Arctic Coastal Plain. From the study Permafrost thaw subsidence, sea-level rise, and erosion are transforming Alaska’s Arctic coastal zone.

Great earthquakes in the 20th century. Inset numbers over the 3 by 12 grid indicate subfaults with large slip in meters from the updated 1957 rupture model with red and blue tones for shallow and deeper megathrust rupture, respectively.
