Aquatic insect eggs are laid on rocks just at the waterline along the Colorado River in Grand Canyon and here they are exposed as the water levels fluctuate. Aquatic insects are an important part of the food base in the Colorado River, providing food for fish, bats, and birds. Aquatic insects need to stay damp to survive and hatch.

The USGS along with the Monterey Bay Aquarium Research Institute (MBARI) funded a pilot study to use a long-range AUV to study limnology of Lake Michigan. The AUV is pictured here being deployed in Lake Michigan to document variation in algae productivity at a whole-lake scale and compare 3-D spatial patterns in chlorophyll a to satellite estimates.

These two NOAA satellite images show Cape San Blas Road in the Florida Panhandle town of Cape San Blas before Hurricane Michael, and after the Category 5 storm. The red circle shows where the USGS sea turtle researchers' field station and seasonal home once stood. The building was demolished down to the concrete slab.

Miriam Jones holding a peat core that was extracted from a thawed permafrost bog at the Alaska Permafrost Experiment (APEX) site at Bonanza Creek LTER, Alaska. The boundary between the formerly frozen permafrost plateau and thawed bog is visible in the peat stratigraphy, with the light-colored peat indicated thawed bog.

It is native to the Great Plains in the United States, where it is known from North Dakota, South Dakota, and Montana.

Hexagon-based aerial survey design with transects overlaid. The EPA 40 km² hexagons (White et al. 2018) were overlaid across the entirety of the northern Gulf of Mexico. Sampled hexagons were then selected using a Generalized Random Tesselation Stratified (GRTS) sampling scheme.

The alfalfa leafcutting bee (Megachile rotundata) is an introduced species common to Southwest Idaho. They originate from the old world, most likely from northeastern Africa or the Middle East. These bees are successful pollinators of various crops and have been imported to North America for use in agriculture and beekeeping.

In August of 2018 this adult female golden eagle was captured and outfitted with a GPS transmitter. You can see the transmitter on the eagle’s back, below the head. This was the first golden eagle ever captured as part of a research project in Yellowstone National Park.

A view of a vegetated inland coastline overlooking the water on Dauphin Island, Alabama. The island protects mainland Alabama’s coastal communities and resources from storms, while also providing recreational opportunities (fishing, beach tourism, etc.) and other economic benefits to the local community and state.

Bat, bird, and insect activity can be monitored with pairs of thermal-imaging cameras mounted on the wind turbines, and automatically recorded to a computer inside the base of the turbine.
