Hawaiʹi’s most widespread native tree, ʹōhiʹa lehua (Metrosideros polymorpha), has been dying across large areas of Hawaiʹi Island mainly due to two fungal pathogens (Ceratocystis lukuohia and Ceratocystis huliohia) that cause a disease collectively known as Rapid ʹŌhiʹa Death (ROD). Here we examine patterns of positive detections of C. lukuohia as it has been linked to the larger mortality events across Hawaiʹi Island. Our analysis compares the environmental range of C. lukuohia and its spread over time through the known climatic range and distribution of ʹōhiʹa. This data set is a georeferenced raster file, containing the projected potential presence of C.lukuohia across the main Hawaiian Islands using climatic...

The data provide location and data quality information for ground control points (GCP) deployed at Palmyra Atoll for acquisition of imagery using small unoccupied aerial systems (sUAS) in October 2016. Thales ProMark 3 handheld geographic positioning systems (GPS) were used as both a local base station and to record locations of individual GCPs, with occupancy times of approximately 30 minutes per GCP. Location data for GCPs were post-processed against base station data using Mobile Mapper Office software to yield local position accuracy of approximately 0.1 m.

The Varzeqan cluster is named for a small village in East Azerbaijan Province, northwestern Iran, about 100 km southeast of Tabriz. It is based on a Mw 5.9 earthquake on November 7, 2019 and its aftershocks. A dozen earlier events were added to improve resolution. Reza Ghods read records from the permanent Iranian network stations. The relocation analysis strongly prefers focal depths near 10 km, or perhaps a little shallower, for all events, but teleseismic depth phases for the November 7 mainshock suggest a depth closer to 20 km, as do the broadband waveforms (Harley Benz, personal communication). ...

This Data Release contains data from the U.S. Geological Survey (USGS) survey of the Oregon outer Continental shelf (OCS) Floating Wind Farm Site in 2014.The backscatter intensity data was collected along with bathymetry data by USGS during the period from August 20 to September 1, 2014, using a Reson 7111 multibeam echosounder. The mapping mission collected bathymetry data from about 163 m to 566 m depths on the Oregon outer continental shelf. The acquisition was funded by the U.S. Bureau of Ocean Energy Management.Within the final imagery, brighter tones indicate higher backscatter intensity, and darker tones indicate lower backscatter intensity. The intensity represents a complex interaction between the acoustic...

To support research on dispersion in river channels, a tracer dye experiment was performed on the Kootenai River in northern Idaho, September 25-27, 2017. This data release provides access to hyperspectral image acquired during the experiment and the supporting field-based measurements of reflectance and dye concentration are available through related data releases. The hyperspectral image data were acquired by Quantum Spatial Inc. (QSI) using the ITRES CASI 1500H imaging system deployed from a Cessna Caravan manned aircraft from a flying height of 1000 m above ground level. Initial geometric and radiometric data processing was performed by ITRES and yielded images with 0.5 m pixels for each of 48 spectral bands...

Maritime Forest Extent This layer is one of the South Atlantic LCC indicators in the maritime forest ecosystem. It captures the overall acres of existing maritime forest present in the South Atlantic geography. Reason for Selection Overall acreage of existing maritime forest provides an indicator of whether maritime forest being inundated by sea level rise are being replaced or restored somewhere else. It is also well monitored and resonates with a diversity of audiences. Since the area occupied by maritime forest shifts over time due to land use change, this extent indicator complements the maritime forest ecosystem map. The ecosystem map attempts to include other potential sites for maritime forest, including...

We used NLCD 2011, SSURGO, and SEGAP data to map the density of desired resources for open pine ecosystems and six focal species of birds and 2 reptiles within the historic range of longleaf pine east of the Mississippi River. Binary rasters were created of sites with desired characteristics such as land form, hydrology, land use and land cover, soils, potential habitat for focal species, and putative source populations of focal species. Each raster was smoothed using a kernel density estimator. Rasters were combined and scaled to map priority locations for the management of each focal species. Species’ rasters were combined and scaled to provide maps of overall priority for birds and for birds and reptiles. For...

This dataset is a repository of calibrated earthquake locations (referred to as the Global Catalog of Calibrated Earthquake Locations, GCCEL or "the Catalog") that have been determined using the Hypocentroidal Decomposition algorithm for multiple event relocation (Jordan and Sverdrup, 1981), as implemented and developed in the program "mloc" by Eric Bergman since 1989. Since the late 1990s, mloc's development has emphasized its use for obtaining calibrated locations, meaning hypocenters with minimal location bias from unknown Earth structure and with reliable estimates of uncertainty. In recent years the program has been widely used by researchers at the United States Geological Survey's National Earthquake Information...

This shapefile is a summary of point count data collected to estimate abundance, showing the distribution of detections in the survey area on Mauna Kea volcano. Data was collected on 13 transects ranging from approximately treeline through the forested area of the mountain. Survey stations were approximately 150 m apart. At each station observers made a six minute count, recording the species of and distance to all birds they observed in that time. Because survey effort varied some (with 2 to 4 visits per station over 2017 to 2018) observed density is presented as count per unit effort == # palila observed / # survey visits in 2017 and 2018.
