Across the desert Southwest, ground void of plant material is prone to soil erosoin and dust storms. In this fallowed agricultural field, we see that a spring breeze can carry away fertile top soil and create air quality concerns.

Усны эргэлт - The Water Cycle, Mongolian

Тэнгэрээс орох борооны дусал бүр, аягалан уух ус болгон чинь шив шинэ гэж чи бодож байж магадгүй. Гэвч энэ ус үргэлж оршсоор ирсэн, усны эргэлтийн нэг хэсэг юм шүү дээ.

Limited information is available about the movements of riverine smallmouth bass in landscapes with prevalent river-reservoir interfaces. This lack of information is especially problematic for the Neosho subspecies of smallmouth bass given the distribution covers an interwoven landscape of rivers and reservoirs.

Topographic “point clouds” (or 3D maps) created by computer processing of air photos show what the Mud Creek area looked like on March 8, 2017 (top), May 19 (center), and May 27 (bottom).

Tables are placed below bat boxes to collect guano from roosting bats during spring/summer. NWHC is investigating use of community guano samples from summer roosts for Pseudogymnoascus destructans (Pd) surveillance.

USGS staff are preparing to deploy the Edgetech 512i sub-bottom profiling system from the stern of a research vessel.  The sub-bottom profiling system was used to map the geologic structure and sediments beneath the seafloor.
