Radar Technology - A Tool for Understanding Migratory Aerofauna

Understanding the factors affecting migratory bird and bat populations during all three phases of their life cycle—breeding, non-breeding, and migration—is critical to species conservation planning. This includes the need for information about these species’ responses to natural challenges, as well as information about the impact of human activities that alter resources critical to migrants...

Water-Quality Sampling at Five Hydrologic Benchmark Stations in the Western United States

The Hydrologic Benchmark Network (HBN) was established in 1963 to provide  Swiftwater Creek, MT long-term measurements of streamflow and water quality in areas of the United States that are minimally affected by human activities. Historically, the HBN has used a fixed-interval sampling strategy, however other more robust sampling strategies are now available. Trend networks, for example, can...

Clinker capped Tongue River Formation near Lame Deer, Montana

Clinker is formed when rock units that overlie exposed burning coal seams are baked and fused. The red and brown clinker is more resistant to erosion than non-baked adjacent Tongue River Formation sandstones and forms caps of many plateaus and buttes. Photo taken north of Lame Deer, Montana.
