Marfac Machine Vision Camera Interface Marfac Machine Vision Camera Interface
This project contains the C# software developed to control and acquire imagery from a FLIR GigE machine vision camera. It is built using the FLIR Spinnaker 64bit SDK version 2.4.0.144 and requires the spinview application and associated dll's. This software was developed using Microsoft Visual Studio 2019 to control and acquire imagery from a GigE machine vision camera (Model: BFS-PGE...
Data release for depth to bedrock derived from Hydrogeology of Southeastern Connecticut by Melvin (1974) Data release for depth to bedrock derived from Hydrogeology of Southeastern Connecticut by Melvin (1974)
This data release consists of a single ESRI shapefile, Hydrogeo_SECTpts, with geologic information from the previously published Hydrogeology of Southeastern Connecticut (Melvin, 1974). Test boring location points digitized from georeferenced area maps (1:24,000 scale) are attributed with associated well log information: town, identification numbers, altitude, depth to bottom, and...
09471580 - San Pedro River at St David, AZ - 2020/10/14 Terrestrial Lidar Data 09471580 - San Pedro River at St David, AZ - 2020/10/14 Terrestrial Lidar Data
This is a terrestrial LiDAR laser scanner dataset collected on October 14, 2020, in response to a flow event that occurred on September 8, 2020, at the USGS streamgage 09471580 - San Pedro River at St David, AZ. The reach scanned for this study is located at the bridge where State Route 80 crosses the waterway. A Leica MS-60 Multistation was used for the laser scanner data collection...
Population genetic data for wild Brook Trout (Salvelinus fontinalis) from the Midwestern United States and selected domestic strains Population genetic data for wild Brook Trout (Salvelinus fontinalis) from the Midwestern United States and selected domestic strains
This dataset includes microsatellite genotypes for 8,454 brook trout from 188 wild Midwestern populations and 26 hatchery strains of both Midwest and eastern (Atlantic seaboard) origin. Each individual was genotyped at either 5 or 7 loci.
2019 Illinois Waterway Aerial Image Mosaics 2019 Illinois Waterway Aerial Image Mosaics
The Corps of Engineers' Rock Island District is planning an unprecedented closure of the Illinois Waterway in 2020 in order to perform required maintenance on locks. Aerial imagery will document river conditions prior to the closure (2019) and after the locks are reopened (2021). Under a separate but related effort, aerial imagery of the entire Illinois Waterway will be collected in 2020...
Digital surfaces and site data of well-screen top and bottom altitudes defining the irrigation production zone of the Mississippi River Valley alluvial aquifer within the Mississippi Alluvial Plain project region Digital surfaces and site data of well-screen top and bottom altitudes defining the irrigation production zone of the Mississippi River Valley alluvial aquifer within the Mississippi Alluvial Plain project region
Site data contained in the ScrIntrvls_AllSrcRefs_AllWellsRev.csv dataset define the top and bottom altitudes of well screens in 64,763 irrigation wells completed in the Mississippi River Valley alluvial aquifer (MRVA) that constitute a production zone in the Mississippi Alluvial Plain (MAP) extending across the midwestern and southern United States from Illinois to Louisiana. Each well...
Hawaii Volcanoes National Park plant community and fire severity data, 2018-2020 Hawaii Volcanoes National Park plant community and fire severity data, 2018-2020
This data release includes metadata and tabular data that document Acacia koa density, basal area, and grass cover before and after the 2018 Keauhou Ranch Fire in Hawaii Volcanoes National Park. Specifically, we asked three questions: 1) At what level of precision can pre-fire grass cover be accurately estimated from oblique aerial photos? 2) How are post-fire Acacia koa regeneration...
Nakula, Maui environmental controls on plant growth and seedling recruitment in a cloud-affected restoration site, 2016-2019 Nakula, Maui environmental controls on plant growth and seedling recruitment in a cloud-affected restoration site, 2016-2019
Fog has been demonstrated to support plant growth, survival and ecosystem maintenance spanning rainfall and elevation gradients across the world. Persistent fog and strong winds on high mountain slopes in Hawai'i create a unique ecological environment. We collected stem diameter measurements of three native plant species at Nakula Natural Area Reserve, Maui, during 2016-2019 and numerous
Tracking Data for Spectacled Eiders (Somateria fischeri) Tracking Data for Spectacled Eiders (Somateria fischeri)
This data release includes 2 child items with tracking data for Spectacled Eiders, a seaduck species that breeds only in Alaska and Russia and spends the winter exclusively in the Bering Sea. The Alaska breeding population is listed as threatened under provisions of the Endangered Species Act. Child Item 1: "Argos Satellite Tracking Data for Spectacled Eiders (Somateria fischeri) -...
Landsat 8 Collection 2 cloud truth mask validation set Landsat 8 Collection 2 cloud truth mask validation set
The U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, SD developed a cloud validation dataset from 48 unique Landsat 8 Collection 2 images. These images were selected at random from the Landsat 8 archive from various locations around the world. While these validation images were subjectively designed by a single analyst, they provide...
Data acquired in laboratory experiments conducted with the crustacean Daphnia magna to characterize Ag bioaccumulation kinetics after exposures to AgNO3 or Ag nanoparticles, 2019-2020 Data acquired in laboratory experiments conducted with the crustacean Daphnia magna to characterize Ag bioaccumulation kinetics after exposures to AgNO3 or Ag nanoparticles, 2019-2020
Silver nanoparticles (AgNP) are one type of contaminant that can enter treatment wetlands (Wiesner 2006) and impact the overall treatment efficacy. Grazing by filter feeding zooplankton, such as Daphnia magna, is critical to treatment wetland functioning (Ismail 2019), but the effects of AgNP on zooplankton are not fully understood, especially at environmentally relevant concentrations...
