Animation of a computed tomography scan of a coral core.

Example of the relationship between CT intensities and measured density of the coral standards used to calibrate data. The measured density of the coral standards are compared to the mean intensities of each standard. Linear regressions calculated from the standard values are then used to calibrate data.

Orbicella spp. coral sample with no packing material. Center of image is darker than edges. Transect across image shows intensity values lower in the center creating a cupping effect.

Bare-earth lidar image of the Nisqually River Delta. Lidar has been used to study and restore the delta, where levees have been removed to reconnect tidal lands.

One image is provided of a landslide near the Monterey-San Luis Obispo County line of Big Sur, California during Feb. 23 and April 6, 2024. The image shows shaded relief topography of the landscape during Feb. 23 and April 6, 2024, and the total topographic change between these dates, which shows both erosion (red) and accretion (blue) of the landscape.

Three images are provided of Mud Creek landslide of Big Sur, California during Feb. 23 and April 6, 2024. The first two images show different oblique perspectives of the landscape topography colored by the actual colors from the photographs. The third image shows shaded relief topography of the landscape during Feb.

An image is provided of the Regent’s landslide of Big Sur, California during Feb. 23 and April 6, 2024. Images show oblique perspectives of the landscape topography colored by the actual colors from the photographs. All 3-dimensional landscape data derived by USGS photogrammetry techniques. 

Two images are provided of the Rocky Creek landslide that resulted in closure of California State Highway 1. The images above show views of the Rocky Creek landslide, California before (Feb. 23, 2024) and after (April 6, 2024) the slope failure. Images show oblique perspectives of the landscape topography colored by the actual colors from the photographs.

An image is provided of the Dolan Point landslide of Big Sur, California during Feb. 23 and April 6, 2024. Images show oblique perspectives of the landscape topography colored by the actual colors from the photographs. All 3-dimensional landscape data derived by USGS photogrammetry techniques.

Location of (A) Baltimore and (B) Norfolk canyons and adjacent slope environments along the U.S. Mid-Atlantic margin. The bathymetry represents 25 m gridded multibeam data with contour lines at every 100 m. Colors on the bathymetric scale represent depth from shallow (red) to deep (blue).

Suspension-feeder isoscapes of Baltimore (A, C) and Norfolk (B, D) canyons with coral distributions outlined in white. Colors represent the different isotopes with cool colors (blues, greens) for δ¹³C data (A, B) and warm colors (pinks, purples) for δ¹⁵N data (C, D), both in ‰.
