Beach topography and nearshore bathymetry of northern Monterey Bay, California, October 2014 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... Tags: AGS

Molokai (Kawela) USGS ridge-to-reef vegetation monitoring study 2009-2014 - raw data file This file contains the raw data collected as part of a vegetation monitoring study that was conducted to assess the changes in plant species frequency inside and outside a fenced exclosure, constructed to eliminate browsing and grazing by feral goats, from 2009-2014 in the US Geological Survey's Kawela research site on the island of Molokai, Hawaii.

0.2-second spectral response acceleration (5% of critical damping) with a 1% probability of exceedance in 1 year for the Western United States This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.05 degrees in latitude and longitude. This particular data set is for horizontal spectral response acceleration for 0.2-second period with a 1 percent probability of exceedance in 1 year. The data are for the Western United States and are based on the long-term 2014 National Seismic Hazard Model.

XYZ files of LiDAR and sonar data collected at Lake Superior at Minnesota Point, Duluth, MN, August 2019 This dataset is comprised of three files containing northing, easting, and elevation ("XYZ") information for light detection and ranging (LiDAR) data representing beach topography and sonar data representing near-shore bathymetry of Lake Superior at Minnesota Point, Duluth, Minnesota. The point data is the same as that in LAS (industry-standard binary format for storing large point clouds) files that were used to create a digital elevation model (DEM) of the approximately 5.9 square kilometer (2.3 square mile) surveyed area. LiDAR data were collected August 10, 2019 using a boat-mounted Optech ILRIS scanner and methodology similar to that described by Huizinga and Wagner (2019). Multi-beam sonar data were collected...

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.
