Orthoimagery and elevation data derived from UAS imagery for Palmyra Atoll, USA 2016-Barren Island

This data set includes a point cloud, digital surface model (DSM), and orthoimagery of Barren Island 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 dimensional point cloud (.las) by identifying pixels from multiple images representing the same object and calculating the x, y, and z coordinates of that object/pixel. Point cloud data were processed to create a 6.4 cm resolution DSM (.tif) of the uppermost reflective surface (i.e., data have not been filtered for vegetation classes or height). Finally, source images were stitched together based on shared pixels and orthoganally adjusted to the DSM to create a 3.2 cm reolution orthoimage (.tif) for the study area.

Brodifacoum toxicity in American kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure - Results of trial 3

A heterologous thrombin clotting time assay (TCT) was used to measure the time for conversion of fibrinogen to fibrin using commercially available reagents. Human reference material included in the kit was diluted with imidazole buffered saline (IBS; 0.0125M imidazole-0.109 M sodium chloride, pH7.4) to generate a standard curve. Each kestrel plasma sample was thawed at 37ºC and diluted with IBS, and following incubation at 37ºC, the reaction was then initiated by the addition of bovine thrombin reagent supplied with the assay kit, with clotting time measured to 0.1 s.  Fibrinogen concentration was determined in a single assay for each of the 3 study trials, with reference samples interspersed among study samples.  The intra-assay variation of kestrel study samples (duplicate determinations for trials 1 and 3) and reference samples (multiple determinations of plasma pools in trials 1, 2 and 3) were calculated.
For Russell’s viper venom time (RVVT), reconstituted RVV Factor X activator was diluted 1:10 with IBS and maintained at room temperature. Citrated plasma samples were diluted with phosphate buffer (8.3 mM phosphate buffer, pH 7.2) (3:5 dilution), incubated at 37ºC and diluted RVV was added and incubated for 10 s.  The clotting reaction was initiated with 25 mM CaCl2, with clotting time measured to 0.1 s.  Baseline and/or terminal study samples, and multiple inter-assay (inter-batch) human reference and kestrel plasma sample pools, were measured using this assay.
For the prothrombin time (PT) assay, crude chicken hatchling thromboplastin (CHT) was prepared by the method of Quick, as modified and previously described (Rattner et al 2010).  Plasma samples were diluted phosphate buffer (4:5 dilution), incubated at 37ºC, and the reaction was initiated by the addition of CHT in 25 mM CaCl2 (1:8 dilution of CHT working solution) with clotting time measured to 0.1 s.  Baseline and/or terminal study samples, and multiple inter-assay (inter-batch) kestrel plasma sample pools, were measured using this assay.

Brodifacoum toxicity in American kestrels (Falco sparverius) with evidence of increased hazard upon subsequent anticoagulant rodenticide exposure - Results of trial 3

Trial examining blood clotting function response in kestrels initially fed a diet containing chlorophacinone (CPN) or brodifacoum (BROD), and following a recovery period, kestrels were challenged with a diet containing chlorophacinone.  Kestrels received two 25 ± 0.1 g NBP meatballs daily for a 7-day period containing either vehicle, 1.5 µg CPN/g wet wt diet (i.e., 1.5 ppm chlorophacinone) or 0.5 µg brodifacoum/g wet wt (i.e., 0.5 ppm brodifacoum) during an initial exposure phase.  Following 7 day recovery period, these kestrels were then fed 0.75 µg CPN/g wet wt diet (i.e., 0.75 ppm chlorophacinone) for a 7 day challenge exposure phase.  Hereafter, these groups are designated control-chlorophacinone challenge (CON-CPN), chlorophacinone-chlorophacinone challenge (CPN-CPN), and brodifacoum-chlorophacinone challenge (BROD-CPN).

National Land Cover Database (NLCD) 2016 Products

The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released four
National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, and 2011.
These products provide spatially explicit and reliable information on the Nation’s land cover and land cover
change. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s
land resources, the USGS has designed a new generation of NLCD products named NLCD 2016. The NLCD 2016
design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land
cover and land cover change database from 2001 to 2016 at 2–3-year intervals. Comprehensive research was
conducted and resulted in developed strategies for NLCD 2016: a streamlined process for assembling and preprocessing
Landsat imagery and geospatial ancillary datasets; a multi-source integrated training data development
and decision-tree based land cover classifications; a temporally, spectrally, and spatially integrated land
cover change analysis strategy; a hierarchical theme-based post-classification and integration protocol for
generating land cover and change products; a continuous fields biophysical parameters modeling method; and
an automated scripted operational system for the NLCD 2016 production. The performance of the developed
strategies and methods were tested in twenty World Reference System-2 path/row throughout the conterminous
U.S. An overall agreement ranging from 71% to 97% between land cover classification and reference data was
achieved for all tested area and all years. Results from this study confirm the robustness of this comprehensive
and highly automated procedure for NLCD 2016 operational mapping.
Questions about the NLCD 2016 land cover product can be directed to the NLCD 2016 land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov. See included spatial metadata for more details.

Sea Otter Capture Data from the Big Sur-Monterey Study (2008-2011)

This data release is comprised of sea otter capture data from the capture of wild sea otters in Big Sur and Monterey, CA between the years of 2008-2011.  These sea otters were captured for tagging and tracking during a comparison study designed to examine the biology, health, and survival of sea otters in a relatively pristine habitat (Big Sur) and a highly-impacted habitat (Monterey).  At the time of capture a variety of data are collected on each individual sea otter.  The otter may receive multiple identifiers including an otter number, color coded flipper tags, a PIT tag, VHF radio transmitter, and archival time-depth recorder.  Capture information (date, time, GPS location and general area, capture team, capture method, if the otter was caught with other otters, if the otter was previously captured) is reported in this data set as well.  A variety of physiological, morphometric, and health parameters are assessed and reported (reproductive status, sex, age class, age estimate, grizzle, nose wound status, weight, length, girth, tail length, right paw width, baculum length [if male], general tooth wear, comments on tooth condition or oral lesions, canine width, overall appearance).  If the otter was caught with a dependent pup, the pup was given an otter number and was sexed, weighed, and measured whenever possible.  Each otter is assigned a blood kit number corresponding to a blood sample.  Release coordinates, methodology, and team are also noted.

LAS digital data files for the U.S.Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming

In 2013 the U.S. Geological Survey (USGS) drilled and logged a continuous core located on the northeast flank of the Alcova anticline in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales (fig. 1).  The well, named the Alcova Reservoir AR–1–13, was spud in the lower part of the Frontier Formation and ended in the upper part of the Cloverly Formation, and recovered core between 40.5 feet (ft) and 623 ft (figs. 1, 2).
After coring was completed the USGS recorded geophysical data from the well bore, with digital data collected to a depth of 622 ft.  Data include natural gamma, resistivity, conductivity, density, sonic, and caliper.  The digital data is presented here in LAS (Log ASCII Standard) format.

Principal components of climate variation in the Desert Southwest for the future time period 2010-2040 (RCP 8.5)

Five principal components are used to represent the climate variation in an original set of 12 composite climate variables reflecting complex precipitation and temperature gradients. The dataset provides coverage for future climate (defined as the 2010-2040 normal period) under the RCP8.5 emission scenario. Climate variables were chosen based on their known influence on local adaptation in plants, and include: mean annual temperature, summer maximum temperature, winter minimum temperature, annual temperature range, temperature seasonality (coefficient of variation in monthly average temperatures), mean annual precipitation, winter precipitation, summer precipitation, proportion of summer precipitation, precipitation seasonality (coefficient of variation in monthly precipitation totals), long-term winter precipitation variability, and long-term summer precipitation variability. The conversion to principal components both standardizes and accounts for covariation in climate variables, while emphasizing the most important climate gradients across the landscape. 
Raster layers representing each principal component form the input to Climate Distance Mapper (https://usgs-werc-shinytools.shinyapps.io/Climate_Distance_Mapper/), an interactive R Shiny application for matching seed sources with restoration sites. Plant populations are commonly adapted to local climate gradients and frequently exhibit a home-site advantage. For this reason, climate information may serve as a proxy for local adaptation in restoration designs. Climate Distance Mapper allows users to rank the suitability of seed sources for restoration sites by displaying multivariate climate distances (incorporating climate principal components) from user-supplied input points to the surrounding landscape. The application provides functions to match seed sources with current or future climate, guide sampling effort for large scale seed collections, and partition the landscape into suitable areas for different seed sources. 
These data support the following publication:
