The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.
This video illustrates differences among the various interpolation methods in ModelMuse.
This video shows how to use ModelMuse to specify layers in MODFLOW that vary in elevation.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from Puerto Rico. Questions include:
- Why has the rainy season been so long in Puerto Rico?
- How is global warming impacting the island of Puerto Rico?

In this briefing USGS demonstrated a new and innovative online decision support system used to identify sources of nutrients to downstream waters, such as the Gulf of Mexico, Long Island Sound and others. The decision support system provides access to six newly-developed regional models that describe how rivers receive and transport nutrients to sensitive waters.

Following the Condit Dam removal, a significant amount of bedload sediment was transported downstream. As the material moved along the river bottom, dunes began to form then collapse. This dune formation is seen through the waveform action as the stream's normal laminar flow is replaced by whitecap wave forms before returning, once again, to laminar flow.

Video showing the fast-moving upper section of the lava stream on the relatively steep eastern flank of Pu‘u ‘Ō‘ō. The video pans to the left to show the smaller lava stream eruption from the lower (eastern) end of the fissure.

Video showing a 6 m (20 ft) high lava cascade near the eastern base of Pu‘u ‘Ō‘ō. This is the same lava stream shown in the previous two videos. The lava stream continues on several hundred more meters (yards) before transitioning into rubbly pāhoehoe and ‘a‘ā and stalling well short of yesterday’s flow front, which is now inactive.

This clip shows a pair of wedge-tailed shearwaters (Puffinus pacificus) as imaged with a camera sensitive to near infrared light. The shearwaters appear out of the night sky at a distance of about 100 meters, and fly along the coast directly towards the camera. This clip demonstrates the application of high-resolution cameras to image nocturnal seabird activity.

The camera was set up to frequently take pictures of the stream during Hurricane Lee. This photography is part of a larger project by the USGS National Research Program, the Virginia Water Science Center and the Maryland Water Science Center examining sediment flow.

This Quicktime video shows recent activity at the lava lake deep within the Halema‘uma‘u vent cavity. Spattering can be seen in the northwest corner (upper left) and a steady stream of lava, coming from an unseen source towards the southeast, is in the lower right. For scale, the lava lake is about 150 meters (164 yards) wide here.

This movie shows views from today's overflight of the vents on the lower west flank of Pu‘u ‘Ō‘ō. There are several vents, topped by spatter cones, that are feeding narrow, fast-moving flows that feed into a broad area of ponded lava.

This Quicktime movie shows views of the numerous spattering vents during today's overflight. Spattering at each source is creating spatter cones and ramparts, and the lava issuing from the individual vents is creating a series of narrow streams which join to feed a broader flow channel.

In April of 2010, Paul Hsieh, a research scientist, readily stepped up to an opportunity to provide a service to the public that pulled him away from his work, that pulled him out of his environment. This was not something that's in his job description, but it was a way for him to make a tangible contribution, and as it turned out, he made a significant difference.
