Guam, Mariana swiftlet nest cluster counts, 2019-2023

The yǻyaguak (Mariana swiftlet; Aerodramus bartschi) is an endangered cave-nesting species historically found on Guam and the southern Mariana Islands, Micronesia. The population on Guam has been severely impacted by the introduction of the brown treesnake (Boiga irregularis). Population status assessments have, however, been challenging due to the limitations of traditional counting methods, which rely on visual observations at cave entrances and are prone to inaccuracies. To improve count accuracy, we estimated yǻyaguak population size and relative nesting activity using thermal and near-infrared videography at Mahlac, Maemong and Fachi Caves from April 2019 to April 2023. This study demonstrates the potential of thermal and near-infrared videography for improved monitoring of yǻyaguak colonies and nesting activity.

Streambank topographic lidar survey of the French Broad River near the Interstate 26 bridge located south of Asheville, NC – December 2021, Mid-construction #2

In January 2020, the North Carolina Department of Transportation (NCDOT) began work on the Interstate 26 (I 26) highway widening project that involves a bridge crossing over the French Broad River (FBR) near Asheville, North Carolina. The U.S Geological Survey (USGS) in cooperation with the NCDOT conducted a pre-construction light detection and ranging (lidar) survey of the streambanks within a one-kilometer reach of the FBR at the bridge construction site in November 2019 (Whaling and others, 2023). In December 2021, a canoe-based repeat streambank lidar survey was collected approximately 23 months after construction began, with the purpose to monitor geomorphological changes to the streambank and inform the NCDOT of potential impacts from construction activities. The survey extended from 300 meters (m) upstream to 700 m downstream from the bridge. Two georeferenced lidar scans were collected; one of the right-descending bank and one of the left-descending bank.  Three-dimensional points of the streambanks were collected with a canoe-mounted Velodyne VLP-16 laser scanner integrated with an SBG Systems Ellipse2-D inertial navigation systems (INS), which consists of dual Global Navigation Satellite Systems (GNSS) receivers and an inertial motion unit. The lidar scanner creates a “point cloud” of lidar returns and the INS computes the position and orientation of the points in three-dimensional space. The navigation solution from the INS was further improved in post processing. Ground points were identified in each point cloud with a Cloth Simulation Filter (Zhang and others, 2016) implemented in CloudCompare software (CloudCompare, 2018) and classified with code 2 (ground) according to the American Society for Photogrammetry and Remote Sensing (ASPRS) standard lidar point classes (ASPRS, 2011).  Water-surface reflections were identified and classified as code 7 (low noise; ASPRS, 2011).  All other points in each point cloud were classified as code 1 (unclassified; ASPRS, 2011). The left and right streambank point clouds are provided as separate LAS files, an industry-standard binary format for storing large point cloud datasets.  Each LAS file is provided with position and elevation data in three dimensions in units of meters, 8-bit scaled intensity, and the classification code. The data are projected in Universal Transverse Mercator (UTM) coordinate system, zone 17 north, horizontally referenced to the North American Datum of 1983 (NGS, 2018a), 2011 realization (NAD83 2011), and vertically referenced to the North American Vertical Datum of 1988 (NAVD88; NGS, 2018b).

Interpolated groundwater levels and altitudes for Monroe County, West Virginia, 2017-2019

These interpolated groundwater levels and altitudes product, for Monroe County, WV, was derived from groundwater-level data obtained from a U.S. Geological Survey (USGS) synoptic survey of 257 groundwater wells during October 23, 2017 through September 19, 2019, and selected points from the National Hydrography Dataset (NHD) to represent equal-altitude contour lines of groundwater altitudes in 50-foot intervals. Attributes include groundwater altitudes in decimal feet. Horizontal coordinates are referenced to UTM zone 17, NAD83, and groundwater altitudes are referenced to the North American Vertical Datum of 1988 (NAVD88). The potentiometric surface map, based on the 257 groundwater measurements, was constrained by the NHD streamlines and location of known springs. ArcGIS Pro was used to make contour lines from point data, and the resulting contours were further edited in areas where automated methods were not as precise given fewer data points; the areas edited were where the land-surface elevation was lower than water-surface elevation, approximately.

Net Sand Isopach Grids of the Lewis Shale in the Eastern Part of the Southwestern Wyoming Province, Wyoming and Colorado

This file contains 15 net sand isopach grids that represent the summed true vertical thickness (TVT) of sand intervals between 15 stratigraphically adjacent horizons picked on borehole geophysical logs in the Southwestern Wyoming Province. In wells where adjacent horizons are missing, no TVT value is calculated. The TVT values are a measure of vertical thickness and do not account for the structural dip of units encountered in the wellbore. The 15 stratigraphic horizons are the tops of 15 regional flooding surfaces F1-15. Net Sand was determined by normalizing gamma ray logs and using a cut-off of 85 API units and then summing each interval. For more detailed stratigraphic information, please see the associated USGS SIM file XXXX, data table, and type log image. This file is a child item of a larger data release titled "Digital Stratigraphic and Structural Grids of the Lewis Shale in the Eastern Part of the Southwestern Wyoming Province, Wyoming and Colorado".

Eastern migratory monarch butterfly population estimates and associated early warning signals (2006-2022)

The long decline of the eastern migratory population of monarch butterflies (Danaus plexippus) appears to have abated in recent years and the population now persists at a much-reduced abundance. Stochastic variation in abundance typical of monarch butterflies, and other insects, places this population at heightened risk of quasi-extinction, a level of abundance below which recovery of the migratory behavior is uncertain. These data and results provide insight into the near-term status and trajectory of the eastern migratory population of monarch butterflies. Within the stationarymonarchdata.csv, overwinter[ha] are annual monarch butterfly overwinter area occupied estimates as provided by World Wildlife Fund-Mexico and breedingcounts are annual indices of Illinois Butterfly Monitoring Network counts of monarch butterflies in summer.

New Source Rock Data for the Niobrara and Sage Breaks intervals of the lower Cody Shale in the Wyoming part of the Bighorn Basin

In 2019 the U.S. Geological Survey (USGS) quantitively assessed the potential for undiscovered, technically recoverable continuous (unconventional) oil and gas resources in the Niobrara interval of the Cody Shale in the Bighorn Basin Province (Finn and others, 2019). Leading up to the assessment, in 2017, the USGS collected samples from the Niobrara and underlying Sage Breaks intervals (Finn, 2019) to better characterize the source rock potential of the Niobrara interval. Eighty-two samples from 31 wells were collected from the well cuttings collection stored at the USGS Core Research Center in Lakewood, Colorado. The selected wells are located near the outcrop belt along the shallow margins of the basin to obtain samples that were not subjected to the effects of deep burial and subsequent organic carbon loss due to thermal maturation as described by Daly and Edman (1987) (fig. 1). Sixty samples are from the Niobrara interval, and 22 from the Sage Breaks interval (fig. 2).

Methylmercury effects on birds: Bibliography and dataset for the development of toxicity reference values for injury assessment

This data release contains three files. The first (Table S1 Bibliography Dataset) contains the entire bibliography for the 435 publications examined for potential inclusion into at least one of the meta-analyses for the effects of environmental mercury (Hg) on birds. For those 168 publications that were included in at least one meta-analysis, the worksheet titled Bibliography contains data describing each sub-dataset, including the type of study, data extraction methods, biological endpoints measured, age class, tissue-residue Hg concentrations, dosing Hg concentrations, the measured effect of Hg, bird taxonomy, life history, and the study’s citation. The worksheet titled Header Explanation describes each column within the Bibliography. The worksheet titled Flowchart describes the process of how the different columns within the Bibliography worksheet can be filtered to produce the studies and sub-datasets that were included within a specific meta-analysis (e.g., combinations of endpoint categories and age classes). The second file (Table S2 Detailed Endpoints) contains the entire list of detailed biological endpoints measured by studies examining the effect of Hg on birds and how they were categorized into the six main endpoint categories (i.e., survival, offspring output, behavior, biochemical, histology, and body morphology) and the three combined endpoints categories (i.e., combined reproduction endpoints, combined survival and reproduction endpoints, and all endpoints during the breeding season). The number of publications and sub-datasets (both for all time periods and those conducted during the breeding season) that quantified each endpoint are listed. The third (Table S3 Data Tables) contains the data used in all 87 meta analyses and shows how each row of data (datapoint used in at least one meta analysis) was categorized into the six main endpoint categories and the three combined endpoint categories. Each of the seven worksheets in the Table S3 Data Tables represents a different type of Hg on the x axis (adult blood-equivalent Hg, egg-equivalent Hg, Hg injected into eggs, maternal dietary Hg for effects on eggs, maternal dietary Hg for effects on juveniles, adult dietary Hg for effects on adults, and juvenile dietary Hg for effects on juveniles).

Structure-from-Motion source images for an inactive perched lava lake formed at Pu'u'o'o (Kilauea) in 2014

Lava flow hazards are usually thought to end when the erupting vent becomes inactive, but this is not always the case. At Kilauea in August 2014, a spiny 'a'a flow erupted from the levee of a crusted perched lava lake that had been inactive for a month, and the surface of the lava lake subsided as the flow advanced downslope over the following few days. Topography constructed from oblique aerial photographs using structure-from-motion (SfM) software shows that the volume of the flow (~68,000 m3) closely matches the volume of subsidence of the crusted lava lake (~64,000 m3). The similarity of these volumes, along with the textural characteristics of the lava, shows that the lava that fed the flow had been stored beneath the surface of the perched lava lake, and that the flow was not generated by reactivation of the vent. This extends the duration of the local lava flow hazard presented by perched lava lakes and similar flow field structures that store lava, such as rootless shields.
