This portion of the USGS data release presents digital elevation models (DEMs) derived from bathymetric and topographic surveys conducted along northern Monterey Bay, California, in September 2017 (USGS Field Activity Number 2017-678-FA). Nearshore bathymetry data were collected using two personal watercraft (PWCs) equipped with single-beam echosounders and survey-grade global navigation satellite system (GNSS) receivers. Topography data were collected using an all-terrain vehicle equipped with a GNSS receiver and on foot with GNSS receivers mounted on backpacks. Additional topography data were collected with a terrestrial lidar scanner. Positions of the survey platforms were referenced to a GNSS base station placed...

This dataset contains the easting, northing and elevation values of the river right and river left endpoints from four to six survey transects at each of 10 sites along the Carmel River, central California. Topographic surveys were completed during four summer surveys (in 2013, 2015, 2016 and 2017). See https://www.sciencebase.gov/catalog/item/5a2720a6e4b03852bafc8eaf for accompanying elevation measurements. All data were collected in NAD83 UTM10N horizontal coordinates and NAVD88 Geoid 12B vertical coordinates, in units of meters.

Topographic surveys were completed during four summer surveys (in 2013, 2015, 2016 and 2017) at 10 sites along the Carmel River, CA. Topographic measurements were made at multiple locations along four to six transects per site using a total station (at sites CR, RS, DM and SH) and with an auto level and survey rod (at sites DDU, DDL, BW, SR, SC and CRO). This dataset contains the cross-sectional elevation measurements for each transect and survey year. The elevation measurement locations along each transect were located by measuring distances between corresponding endpoint coordinates, starting from river left (see https://www.sciencebase.gov/catalog/file/get/5a271f8ce4b03852bafc8eaa for transect endpoint locations)....
