Dataset contains 32 terrestrial lidar scans of conifer forests and associated shapefile of locations in Sequoia and Kings Canyon National parks from the summer of 2022. These scans were co-located within field plots from a larger ongoing U.S. Geological Survey (USGS) project collecting wildfire fuels and forest structure data (informally known as the Fire and Fuels Project). These data...

This study presents Raman spectroscopic data paired with scanning electron microscopy (SEM) to assess solid bitumen composition and porosity development as a function of solid bitumen texture and association with minerals. A series of hydrous pyrolysis experiments (1-103 days, 300-370°C) using a low maturity (0.25% solid bitumen reflectance, BRo), high total organic carbon [(TOC), 14.0...

In May 2023, the U.S. Geological Survey provided training for bathymetric data acquisition and processing for the Iraq Ministry of Water Resources. The training included multibeam sonar theory, survey planning, data collection and processing, and dissemination. This data release presents the raw survey data, a digital elevation model (DEM), and a thalweg shapefile for three survey areas...

The information provided in the Contaminant Exposure and Effects-Terrestrial Vertebrates (CEE-TV) Database profiles available geo-referenced information on contaminant exposure and effects in terrestrial vertebrates along the U. S. Atlantic, Gulf, and Pacific coasts (including Hawaii and Alaska) and the Great Lakes.

R code to evaluate the effects of wastewater reuse on smallmouth bass (Micropterus dolomieu) relative abundance in the Shenandoah River Watershed, USA

The U.S. Geological Survey (USGS) has developed and implemented an algorithm that identifies burned areas in temporally dense time series of Landsat Analysis Ready Data (ARD) scenes to produce the Landsat Burned Area Products. The algorithm uses predictors derived from individual ARD Landsat scenes, lagged reference conditions, and change metrics between the scene and reference...

This data product consists of a database of population change and abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented for 548 species of birds in 4 spreadsheets containing trend estimates and annual indices for 2 time periods. Estimates are derived for each species using the 1 of 4 alternative models, and a cross

Understanding how routing modifications influence survival of juvenile Chinook salmon (Oncorhynchus tshawytscha) is complex because reach-specific survival and routing at key river junctions in the North Delta each have a different relationship with river flow. Therefore, to facilitate understanding of how routing modifications at key river junctions influence through-Delta survival, we...

This data set was generated to evaluate the status and response of oysters within Chicopit Bay, FL, in the Timucuan Ecological and Historic Preserve during and following dredging completed by the Army Corps of Engineers for the Mile Point Project. It includes live oyster area estimates from aerial images collected in 2016-2018.

This data release contains data associated with the journal article, “Comparison of δ13C Analyses on Individual Foraminifer (Orbulina universa) Shells by Secondary Ion Mass Spectrometry and Gas-Source Mass Spectrometry”. Data tables are comprised of stable carbon isotope (δ13C) measurements of planktic foraminifer (Orbulina universa) shells measured by secondary ion mass spectrometry...
