In the Arctic, rivers are often thought to freeze completely during winter. Since fish need liquid water to survive, there are few places where they can live. Fish usually inhabit deep river channels and areas where springwater enters a stream.

Title: The Story of California's Changing Ecosystems: As observed from space

• How can we use images from space to help us understand changes to our coasts, rangelands, forests and wildlife habitats?
• How can they help to predict future changes?
• What more can we learn from advances in earth observing technologies?

Video shows periphyton growth along the nearshore of Lake Tahoe. 
 

The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor is located aboard NASA’s Terra and Aqua satellites. These data are crucial for studying changes that have occurred on the surface of the Earth, including during times of drought.

This wide-angle video shows the southwest portion of Kīlauea caldera in the area of Halema‘uma‘u. Faint plumes of volcanic gas are rising from yellow fumaroles on the walls of the deep conical pit. Overall, no significant changes were observed at the summit on today's overflight.

In these videos, speakers discuss upcoming changes to the USGS National Water Quality Program (NAWQA Project) and three new priority areas for the USGS Water Mission Area. Gary Rowe discusses plans for transitioning from current NAWQA Project activities to the new priority areas.

Forests around the world are experiencing increasingly hot and severe drought conditions, and drought severity is expected to increase as temperatures rise in coming decades, particularly in the already hot and dry Southwest U.S.

Title: Land Subsidence: The Lowdown on the Draw-down

The link between groundwater use and sinking landscapes

A USGS crew used new drone technology to test and evaluate new technology to measure water speed from the air without touching the water. This drone footage was taken on the Missouri River at Hermann, Missouri on March 27, 2019. Scientists compared these new method results to the conventional way of taking measurements from a boat. 

Ice jam was holding on upstream side of bridge an suddenly broke lose while in the process of making a streamflow measurement. Equipment pulled to safety, and this video taken about 5 minutes later.
 

This episode features Jay Stevens (GIS Specialist BLM – Oregon/Washington) Jay presents BLM’s collaboration efforts with the Forest Service, the Oregon Department of Forestry, Oregon Department of Geology and Mineral Industries, NRCS to delineate Western Oregon with new lidar-derived NHD and WBD.

This 3D model of the Pu‘u ‘Ō‘ō crater was constructed from thermal images taken during a recent helicopter overflight. White areas show warm spots in the crater. Despite the absence of active lava in Pu‘u ‘Ō‘ō, changes at the crater have continued since magma drained from beneath it on April 30, 2018.
