Summary
This data release presents digital elevation models (DEMs) derived from bathymetric and topographic measurements collected offshore of Santa Cruz, CA, from 2014 to 2024. Bathymetry data were collected using two personal watercraft (PWCs), each equipped with single-beam echosounders and survey-grade global navigation satellite system (GNSS) receivers. Topography data were collected on foot with GNSS receivers mounted on backpacks at a measured height above the ground. DEM surfaces were produced from all available elevation data using linear interpolation.

Digital elevation models (DEMs) of the beach and nearshore in Santa Cruz, California
Digital elevation models (DEMs) were produced from bathymetric and topographic measurements collected offshore of Santa Cruz, CA, from 2014 to 2024. Bathymetric data were collected using personal watercraft (PWCs) equipped with single-beam echosounders and dual frequency global navigation satellite system (GNSS) receivers. Topographic data were collected on foot with GNSS receivers mounted on backpacks. Bathymetric and topographic data were collected primarily along a series of cross-shore transects at 50-m intervals along the coast. Continuous surfaces were produced from all available elevation data using linear interpolation with a resolution of 2 m.
