Bathymetric change off the Washington-Oregon coast Bathymetric change off the Washington-Oregon coast

Historical hydrographic data from the Washington/Oregon shelf are compared for the first time to identify bathymetric change on a regional scale. Offshore data sets exist for four time periods: 1800s, pre-1950s, post-1950s, and 1990s.

Evaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast Evaluation of landslide hazards with ground-penetrating radar, Lake Michigan coast

Ground-penetrating radar (GPR) and boreholes were used to investigate a landslide-prone bluff at Sleeping Bear Dunes National Lakeshore on the northeastern coast of Lake Michigan. Based on borehole observations, sediment underlying the area is homogeneous, consisting of well-sorted, medium to coarse sand. GPR penetrated up to 20 m deep in these sediments, revealing the late Quaternary...
