This USGS data release presents data collected during surveys of nearshore bathymetry and beach topography from northern Monterey Bay, California. Survey operations were conducted between October 20 and October 24, 2014 (USGS Field Activity Number 2014-676-FA). Nearshore 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 using an all-terrain vehicle equipped with a GNSS receiver and on foot with GNSS receivers mounted on backpacks. Positions of the survey platforms were referenced to a GNSS base station with known horizontal and vertical coordinates. Depths...

This data release presents beach topography and nearshore bathymetry data from repeated surveys in northern Monterey Bay, California to document changes in shoreline position and coastal morphology as they relate to episodic (storms), seasonal, and interannual and longer (e.g. El Niño) processes. The ongoing monitoring program was initiated in October 2014 with semi-annual surveys performed in late summer (September or October) and Spring (March). Nearshore bathymetry and topography data were collected along a series of shore-perpendicular transects spaced primarily at 50-250 m intervals between Santa Cruz and Moss Landing, California (fig. 1). The transects were located along sandy stretches of the coastline...

Time-series data of water-surface elevation, wave height, water-column currents, temperature were acquired for 6 days off the north coast of the island of Kauai, Hawaii in support of a study on the coastal circulation patterns and groundwater input to the coral reefs of Makua.
Groundwater emergence and shoaling extents are derived from water table GeoTIFFs, which are calculated as steady-state groundwater model heads subtracted from high-resolution topographic Digital Elevation Model (DEM) land surface elevations. Results are provided as shapefiles of water table depth in specific depth ranges, with the following data coding in the "fbin_m" data column: -1 = marine inundation (below marine boundary condition (LMSL or MHHW) sea level) 0 = water table at or above ground surface (emergent groundwater) 1 = water table between 0-1 m depth (very shallow) 2 = 1-2 m depth (shallow) 5 = 2-5 m depth (moderate) 6 = > 5 m depth (deep) Model results are aggregated by County, with separate County...

This USGS data release presents data collected during surveys of nearshore bathymetry and beach topography from northern Monterey Bay, California. Survey operations were conducted between March 7 and March 14, 2017 (USGS Field Activity Number 2017-620-FA). Nearshore 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 using an all-terrain vehicle (ATV) equipped with a GNSS receiver and on foot with GNSS receivers mounted on backpacks. A terrestrial lidar scanner was used to obtain high-resolution topography data along portions of the survey area inaccessible...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
