A Kelp Crab (Pugettia producta) captured in a beach seine during a 2012 Bainbridge Island larval forage fish survey.  This survey focused on the abundance, habitat use, and food habits of larval forage fish (surf smelt and sand lance) and was conducted by scientists from the Columbia River Research Laboratory -Western Fisheries Research Center.

Weir control at Beaver Creek below Linton, North Dakota.  For more information on the use of weirs to aid in the determination of streamflow, see volumes 1 and 2 of the USGS Water Supply Paper, Measurement and Computation of Streamflow.

A hydraulic fracturing operation is underway at this drilling pad in the Marcellus Shale gas play of southwestern Pennsylvania.

Wetlands Reserve Program site in Natchitoches Parish, Louisiana.  Ten years ago, this landowner worked with the USDA Natural Resources Conservation Service through the Wetlands Reserve Program to design and construct this slough as part of a plan to restore this field’s natural wetland hydrology.

IGBST researchers are very careful to keep the bear under shade and protected from the elements while they collect biological data.

USGS scientists return from an alpine ecosystem study site in Glacier National Park where they are researching and monitoring potential impacts of climate change on mountain ecosystems.

A massive forest die-off is projected to occur more frequently in the Southwest. Piñon pines, normally evergreen, have reddish-brown foliage in October 2002 (left). By May 2004 (right), the dead piñon pines have lost all their needles, exposing gray trunks and branches. The photos were taken from the same vantage point near Los Alamos, N.M.

Scientists at the USGS Upper Midwest Environmental Sciences Center view young freshwater mussels through miscroscopes. During laboratory tests, USGS scientists and partners found that the heart and growth rates of some species of young freshwater mussels declined as a result of elevated water temperatures, and many died.

This image of live silver carp larvae was taken with a microscope camera at the USGS Columbia Environmental Research Center. Asian carp are invasive species that could pose substantial environmental risks and economic impacts if they become established.

These juvenile silver carps are used to find potential physical, biological or chemical controls as part of an integrated pest management approach for natural resource managers.
