Digital three-dimensional rendering of the coastal cliffs around Point Dume in Malibu, California. Cliff feature outputs from the Cliff Feature Delineation Tool are shown to conceptually display the cliff delineation process, including cross-shore transects (green), the cliff top line (red), the cliff toe line (blue), and subsidiary cliff features (orange).

Evolution of the shoreline around the Elwha River mouth, Washington, before, during and after dam removal, 2011–2017. Two large dams were removed from the Elwha River between 2011 and 2014 in the largest dam removal worldwide thus far, releasing more than 20 million tons of sediment downstream.

Once removed from the pressure core testing tool, this specimen shows that it is not a homogeneous sediment.  The mostly fine-grained sample (dark sediment in all three images) easily breaks apart at a thin layer of coarse-grained sediment (light sediment on the inner core surfaces of images (i) and (ii).

Red plumes burst out from the tops of these chemosynthetic tubeworms, capturing hydrogen sulfide and oxygen from the surrounding water to feed their bacterial endosymbionts. The tubeworm tubes provide a habitat for several benthic animals, including the pale pink branching octocorals seen here
