High-resolution (1 m) digital elevation model (DEM) of San Francisco Bay, California, created using bathymetry data collected between 1999 and 2020 (ver. 2.0, July 2021) High-resolution (1 m) digital elevation model (DEM) of San Francisco Bay, California, created using bathymetry data collected between 1999 and 2020 (ver. 2.0, July 2021)
A 1-m resolution bathymetric digital elevation model (DEM) of all off San Francisco Bay was constructed from bathymetric surveys collected from 1999 to 2016. The DEM has been divided into northern and southern sections due to file size, and is available in both MLLW and NAVD88 versions. Background: In 2014 and 2015 the California Ocean Protection Council (OPC) contracted the collection...
Hydrologic, slope movement, and soil property data from the coastal bluffs of the Atlantic Highlands, New Jersey, 2016-2018 Hydrologic, slope movement, and soil property data from the coastal bluffs of the Atlantic Highlands, New Jersey, 2016-2018
Seasonal variations in vegetation, rainfall, and soil moisture conditions have the potential to impact the slope stability of locally forested coastal bluffs in the Atlantic Highlands of New Jersey. Both the seasonality and rainfall amounts of the two types of storms that induce shallow landslides in the area vary considerably. Most of the documented historical landslides are the result...
Monitoring data from the Aleppo rockslide, Allegheny County, Pennsylvania, November 2013 - December 2018 Monitoring data from the Aleppo rockslide, Allegheny County, Pennsylvania, November 2013 - December 2018
Upon reactivation, movement of deep-seated landslides in the Greater Pittsburgh region may persist for long periods of time. Monitoring equipment was located at two sites on a deep-seated rockslide in Aleppo Township, Pennsylvania to establish relationships between precipitation and changes in the state of activity and velocity. Precipitation, snow depth, and air temperature are...
Sedimentologic Data from Point aux Chenes Marsh and Estuary, Mississippi Sedimentologic Data from Point aux Chenes Marsh and Estuary, Mississippi
Sediment samples, including marsh and estuarine surface samples and marsh push and peat-auger cores, were collected from Point aux Chenes, Mississippi from October 23–26, 2018, and August 4, 2021. Marsh surface samples (top 1 centimeter (cm) of sediment; sample names appended with S), marsh push cores (core names appended with M) and peat-auger cores (core names appended with R) were...
Select model results from simulations of hypothetical rapid failures of landslides into Barry Arm, Prince William Sound, Alaska Select model results from simulations of hypothetical rapid failures of landslides into Barry Arm, Prince William Sound, Alaska
This data release contains model output from simulations presented in the associated Open-File Report (Barnhart and others, 2021). In this report, we present model results from four simulations (scenarios C-290, NC-290, C-689, NC-689, Table 1) of hypothetical rapid movement of landslides into adjacent fjord water at Barry Arm, Alaska using the D-Claw model (George and Iverson, 2014...
Compilation of in situ and detrital zircon U-Pb ages for the Jurassic-Paleocene North American Cordillera (28-50 degrees north) Compilation of in situ and detrital zircon U-Pb ages for the Jurassic-Paleocene North American Cordillera (28-50 degrees north)
This document includes two suites of zircon U-Pb ages that help to characterize the magmatic and sedimentary history of the North American Cordillera between ~28 and 50 degrees north. The first dataset is a compilation of published zircon U-Pb ages of igneous rocks associated with the Mesozoic-Cenozoic North American Cordilleran arc. The compilation of igneous zircon data includes 1,492...
