Two views from the Rainbow Falls overlook, downstream of the Wailuku River streamgage near Hilo, Hawaii. The image on the left shows a typical base flow of about 35 cubic feet per second (cfs). The image on the right shows the early impact of Hurricane Lane with a flow of about 26,000 cfs taken at 8:35 a.m. HST, August 23, 2018. This U.S.

Looking up at a drone hovering near an open-path methane analyzer mounted on a flux tower. Instruments mounted on both the towers and on the drones are measuring gases emitted from the soil.

GeoGirls analyze volcanic sediment at the Coldwater Lake outlet.

GeoGirls take core samples at a pond near the Hummocks Trail to study groundwater transport.

The GeoGirls examined tephra (ash and pumice) deposits from Mount St. Helens’ eruptive past and learned how to create a stratigraphic column.

Many bumble bee species have declined in recent decades due to changes in habitat, climate, and pressures from pathogens, pesticides and introduced species. The western bumble bee, once common throughout western North America, is a species of concern and is being considered for listing by the U.S. Fish and Wildlife Service under the Endangered Species Act.

USGS scientist Nick Voichick rafted about 150 miles in nine days on the Grand Canyon portion of the Colorado River to collect groundwater samples from springs in remote locations. 

 

USGS scientists Tom Porter and Joel Unema warm up in the sun as the scientific expedition moves downstream to the next sample location.

USGS scientists Kim Besiner, John Solder and Kate Wilkins collect groundwater samples at Grapevine Main Spring. 

Scientists traveled to the remote locations along the south rim of the Grand Canyon to assess the potential effects of mining along the Coconino Plateau and groundwater withdrawals associated with increasing populations.

USGS scientist Joel Unema hikes to National Canyon Spring to collect groundwater samples from a remote location near the south rim of the Grand Canyon. Joel Unema was part of a group of USGS and National Park Service scientists that rafted 150 miles in nine days to better understand natural resources.
