National assessment of shoreline change: A GIS compilation of vector shorelines and associated shoreline change data for the north coast of Alaska, Icy Cape to Cape Prince of Wales National assessment of shoreline change: A GIS compilation of vector shorelines and associated shoreline change data for the north coast of Alaska, Icy Cape to Cape Prince of Wales
Beach erosion is a persistent problem along most open-ocean shores of the United States. Along the Arctic coast of Alaska, coastal erosion is widespread and threatens communities, defense and energy-related infrastructure, and coastal habitat. As coastal populations continue to expand and infrastructure and habitat are increasingly threatened by erosion, there is increased demand for...
Orthophotomosaics, elevation point clouds, digital surface elevation models and supporting data from the north coast of Barter Island, Alaska Orthophotomosaics, elevation point clouds, digital surface elevation models and supporting data from the north coast of Barter Island, Alaska
Aerial photographs were collected from a small, fixed-wing aircraft over the coast of Barter Island, Alaska on three separate dates: July 01 2014, September 07 2014, and July 05 2015. Precise aircraft position information and structure-from-motion photogrammetric methods were combined to derive high-resolution orthophotomosaics and elevation point clouds. Ground control acquired using...
Beach topography and nearshore bathymetry of northern Monterey Bay, California Beach topography and nearshore bathymetry of northern Monterey Bay, California
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 Ni?o) processes. The ongoing monitoring program was initiated in October 2014 with semi-annual surveys...
Digital Elevation Model of Little Holland Tract, Sacramento-San Joaquin Delta, California, 2015 Digital Elevation Model of Little Holland Tract, Sacramento-San Joaquin Delta, California, 2015
This USGS Data Release presents data collected from bathymetric and topographic surveys and the resulting digital elevation model for the Little Holland Tract in the Sacramento-San Joaquin River Delta, California. During May and June of 2015, a team of scientists from the USGS Pacific Coastal and Marine Science Center (PCMSC) conducted multiple surveys (USGS Field Activity 2015-642-FA)...
