Preliminary seafloor bathymetry (shown in colors) collected by the USGS research vessel Parke Snavely on July 11, 2017. Relative depths shown in color, superimposed on a shaded-relief map from the June 26 USGS air-photo survey. Note white data gap next to the shore where water was too shallow for the Snavely to map.

USGS scientists continue to monitor the slide by collecting imagery every couple of weeks, weather permitting. Pilot Bob Van Wagenen, contracted through the Department of the Interior’s Office of Aviation Services, takes air photos for Jon Warrick’s Big Sur Landslide team, flying out of the Watsonville Municipal Airport in a Cessna 182R.

Scanning Electron Microscope (SEM) images of fossilized diatom specimens (microfossils). Diatoms are microscopic phytoplankton (algae) that are found in aquatic environments all over the world. Plankton species have preferences for different water and environmental conditions, such as salt or fresh water, attaching to sand or vegetation, or river versus estuary.

In 2017, the massive Mud Creek landslide buried a quarter-mile of the famous coastal route, California’s Highway 1, with rocks and dirt more than 65 feet deep. USGS monitors erosion along the landslide-prone cliffs of Big Sur, collecting aerial photos frequently throughout the year.

“Variance” image produced from video shot at Madeira Beach, Florida, on June 20, 2017. The more the light intensity changes at a given spot, or “pixel,” during the video, the brighter the value assigned to that pixel. Motion tends to produce changes in light intensity. Note bright bands parallel to shore where waves were breaking.

Time-averaged image, or “timex,” created by averaging the intensity of light recorded at each spot, or “pixel,” during a 17-minute video taken at Madeira Beach, Florida, on June 20, 2017. Blurred white bands show where waves are breaking. Offshore band shows location of a sand bar.
