SCINet as a Resource for Safeguarding and Advancing ARS's Biological Collections
Across the USDA’s Agricultural Research Service (ARS) there are nealy 100 biological collections containing millions of preserved and viable specimens including animal tissues, seeds, fungal cultures, plant accessions, pinned insects, and viral isolates. These specimens and the data about them document and support ARS research efforts and are an integral part of delivering on the Agency’s mission.

Monte Carlo simulations on Atlas for soil content determinations
The Monte Carlo Method, or multiple probability simulation, is a mathematical technique used to estimate possible outcomes of uncertain events. The Monte Carlo Method was applied for nuclear problems by John von Neumann and Stanislaw Ulam during work on the Manhattan Project.

SCINet Resources for Photogrammetry
Scientists at the NWRC use UAS to research long-term vegetation dynamics in sagebrush-dominated rangelands. Multispectral, hyperspectral, and natural color imagery are collected to study the effects of fire, grazing, and invasive weed encroachment.

CameraTrapDetectoR: Detecting, Classifying and Counting Animals in Camera Trap Images
The use of camera traps is a popular and cost-effective way to monitor animal populations, evaluate animal behavior, and study ecological processes influencing populations. However, a camera trap dataset for a single site or research question can result in millions of images that require classification to be useful for analysis.

Use of UAS Imagery to Detect Prairie Dog Burrows, Map Burrow Density, and Estimate Colony Acreage
Dr. Kearney is using unmanned aerial system (UAS) imagery to detect individual prairie dog burrows, map burrow density and, ultimately, estimate colony acreage within managed rangelands.
-
Exploring Methods for Developing 3D Maps of Soil Organic Carbon
Scientists at the Cropping Systems and Water Quality Research Unit in Columbia, Missouri have extensive experience estimating soil biological, physical, and chemical properties using proximal soil sensors.

Guidemaker: software for CRISPR based gene function discovery
CRISPR-Cas is a powerful tool for gene editing. CRISPR can also be used to discover gene function by disrupting every gene in the genome and screening millions of cells in parallel.

SCINet accelerates development of a big-data driven and inter-disciplinary technology platform for soybean post-genomic research
Soybean (Glycine max (L.) Merr.) is a versatile, nutrients-laden, economically invaluable crop with capacity to restore soil fertility through atmospheric nitrogen fixation. It holds great significance in ensuring adequate global nutritional food security and environmentally friendly sustainable agriculture.

Putting flowers on the map: Quantifying spatio-temporal patterns in floral resources for pollinators
Flowers provide critical nectar and pollen resources to support foraging, learning and memory, and reproduction of pollinating insects, but there are very few large-scale maps of floral resources for pollinators.
