Orthoimagery and elevation data derived from UAS imagery for Palmyra Atoll, USA 2016-Fighter Strips

This data set includes a point cloud, digital surface model (DSM), and orthoimagery of the Fighter Strips at Palmyra Atoll, USA. Products were generated from aerial images collected in October 2016 using Unoccupied Aerial Systems (UAS, or "drones") with a Ricoh GRII digital camera. Imagery was processed using structure-from-motion photogrammetry that generates a three dimensio

Orthoimagery and elevation data derived from UAS imagery for Palmyra Atoll, USA 2016 (ver. 1.1, November 2020)

Point clouds, high resolution digital surface models (DSM), and high resolution orthoimagery of Palmyra Atoll, USA, were generated from aerial 3-color and 5-band imagery collected October 2016 using Unoccupied Aerial Systems (UAS, or "drones"). Data were processed in sections corresponsing to flight areas using photogrammetry to generate three-dimensional point clouds (.la

Hybrid bathymetric-topographic digital elevation model for a 20-km reach of the Missouri River downstream from Wolf Point, MT

The dataset is a digital elevation model (DEM) for a 20-km reach of the Missouri River downstream from Wolf Point, MT. Channel topography was generated from data collected by USGS staff from the Columbia Environmental Research Center during single-beam sonar surveys of the channel bed in June 2018 and terrestrial light detection and ranging (LiDAR) surveys of channel banks in September

Woody species crown and vegetation community data, Palmyra Atoll, 2016

Photo-interpretation of high-resolution aerial imagery was used to delineate individual stems of select woody species and to map vegetation communities at Palmyra Atoll, USA. Imagery collected using Unoccupied Aerial Systems in October, 2016, as well as derived elevation and mosaicked orthoimagery, were used to delineate individual crowns of coconut, Pisonia and other selected woody spe

Change in fire probability from baseline to 2070-2099 using GFDL-projected climate values

Globally, changing fire regimes due to climate is one of the greatest threats to ecosystems and society. This dataset presents projections of historic and future fire probability for the southcentral U.S. using downscaled climate projections and the Physical Chemistry Fire Frequency Model (PC2FM, Guyette et al., 2012). Climate data from 1900-1929 and projected climate data for 2040-2069 and...

Chronic toxicity of azoxystrobin to freshwater amphipods, midges, cladocerans, and mussels in water-only exposures-Data

Understanding the effects of fungicides on non-target organisms at realistic concentrations and exposure durations is vital for determining potential impacts on aquatic ecosystems. Environmental concentrations of the fungicide azoxystrobin have been reported up to 4.6µg/L in the United States and 30 µg/L in Europe. The objective of the present study was to evaluate the chronic toxicity of...

Survival, growth and reproduction of the amphipod Hyalella azteca in 42-d water only treatments with and without the addition of bromide

Poor survival, growth and reproduction of the amphipod Hyalella azteca has been observed in exposures using reconstituted waters. Previous studies have reported success in H. azteca water-only exposures with the addition of relatively high concentrations of bromide (Br). This study evaluated the influence of lower environmentally representative concentrations of Br on the response of the...
