Data compiled from stratigraphic and tree-ring studies of late Holocene earthquakes and tsunamis at Copalis River, Grays Harbor, Willapa Bay, and Columbia River, Washington and Oregon Data compiled from stratigraphic and tree-ring studies of late Holocene earthquakes and tsunamis at Copalis River, Grays Harbor, Willapa Bay, and Columbia River, Washington and Oregon
This dataset consists of tabular information from coastal studies of earthquake and tsunami history along a central part of the Cascadia Subduction Zone. The study area encompasses four estuaries along the Pacific coast of southern Washington and northernmost Oregon. Nearly all the field work took place between 1986 and 1998. Data tables, 18 in all, archive mostly georeferenced...
Eight Multichannel Seismic Reflection Lines Acquired as Part of a Seismic Evaluation of the Oil and Gas Resource Assessment of the Naval Oil Shale Reserve 2 (NOSR 2), Utah Eight Multichannel Seismic Reflection Lines Acquired as Part of a Seismic Evaluation of the Oil and Gas Resource Assessment of the Naval Oil Shale Reserve 2 (NOSR 2), Utah
This data release contains seismic data for eight (8) two-dimensional (2D) multichannel seismic reflection (MCS) lines recorded in 1981 in Utah as part of a Seismic Evaluation of the Naval Oil Shale Reserve 2 (NOSR 2) commissioned by the U.S. Department of Energy (DOE). The lines are designated TRW-1 through TRW-8. This release includes original digital field data, including support...
Water column properties and temporal hydrologic and chemical records from flooded caves (Ox Bel Ha and Cenote Crustacea) within the coastal aquifer of the Yucatan Peninsula, Quintana Roo, from December 2013 to January 2015 Water column properties and temporal hydrologic and chemical records from flooded caves (Ox Bel Ha and Cenote Crustacea) within the coastal aquifer of the Yucatan Peninsula, Quintana Roo, from December 2013 to January 2015
Natural cave passages penetrating coastal aquifers in the Yucatan Peninsula (Quintana Roo, Mexico) were accessed to investigate how regional meteorology and hydrology control dissolved organic carbon and methane dynamics in karst subterranean estuaries, the region of aquifers where fresh and saline waters mix. Three field trips were carried out in December 2013, August 2014, and January...
Grain-size analysis data of sediment samples from the beach and nearshore environments at the Pea Island National Wildlife Refuge DUNEX site, North Carolina in 2021 Grain-size analysis data of sediment samples from the beach and nearshore environments at the Pea Island National Wildlife Refuge DUNEX site, North Carolina in 2021
These data provide grain-size measurements from sediment samples collected as part of the USGS DUring Nearshore Event eXperiment (DUNEX) site on Pea Island National Wildlife Refuge, NC. DUNEX is a multi-agency, academic, and non-governmental organization collaborative community experiment designed to study nearshore coastal processes during storm events. USGS participation in DUNEX will...
Data for analysis of open removal models with temporary emigration and population dynamics to inform invasive animal management Data for analysis of open removal models with temporary emigration and population dynamics to inform invasive animal management
This data release includes the data and computer code that we produced to fit two open-robust design removal models developed to simultaneously model population dynamics, temporary emigration, and imperfect detection: a random walk linear trend model (estimable without ancillary information), and a 2-age class integrated population model (IPM) that used prior information for age...
Sagebrush Restoration Following Fire Disturbance in the Virginia Mountains, Nevada (2018) Sagebrush Restoration Following Fire Disturbance in the Virginia Mountains, Nevada (2018)
We developed a framework that strategically targets burned areas for restoration actions (e.g., seeding or planting sagebrush) that have the greatest potential to positively benefit Greater Sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) populations through time. Specifically, we estimated sagebrush (Artemisia Spp.) recovery following wildfire and risk of non-native annual...
