Land Change Monitoring, Assessment, and Projection (LCMAP) - A new way of presenting where, how and why land change has occurred.
 

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US.

The Arizona Water Science Center demonstrates new methods in Reach-Scale Monitoring to improve accuracy and measurability of high flow events. By installing pressure transducers and using LiDAR to measure topography data, hydrologists are able to simulate flows with two dimensional models which will help better calibrate stream gages.

SEABed Observation and Sampling System (SeaBOSS) operations were conducted north of Nantucket, MA as part of an agreement with Massachusetts Coastal Zone Management to map the geology of Massachusetts waters .

Title: Underwater Secrets of the Hayward Fault Zone: Integrated 3D imaging to understand earthquake hazards 

The USGS Hydrography Seminar Series shares success stories from users, provides information on the National Hydrography Dataset (NHD), Watershed Boundary Dataset (WBD), NHDPlus High Resolution (NHDPlus HR), and other related products, and provides a forum for users to learn more about hydrography-related topics. Seminar 9 is an overview of the NHDPlus HR.

Image of the Week: Okefenokee National Wildlife Refuge Fire



Landsat 8's Operational Land Imager captures the scene as many acres burn in the Okefenokee National Wildlife Refuge.



Series Description:

Permanent Site: H1 East Transect; Depth: 5.9 Meters (19.5 Feet); Distance from river mouth: 2.4 Kilometers (1.5 Miles) east; Pre/Post Dam Removal: 6 years post-dam removal; Lat/Long: 48.1479177,-123.53472865; Site Description: This is a shallow site and one of the farthest removed from the effects of the sediment plume outside of the control sites.

This time-lapse sequence shows the outgassing plume from the Halema‘uma‘u lava lake at the summit of Kīlauea. The images were captured by a camera on the flank of Mauna Loa on May 19, 2017. As the plume rose from the vent, it reached the atmospheric inversion layer, which effectively capped the height of the plume.

This webinar was recorded on May 18, 2017 as part of the Climate Change Science and Management Webinar Series, held in partnership by the USGS National Climate Change and Wildlife Science Center and the USFWS National Conservation Training Center. 

• Corrosive groundwater, if untreated, can dissolve lead and other metals from pipes.
• National maps have been prepared to identify the occurrence of potentially corrosive groundwater in the U.S.
• These findings have the greatest implication for the 44 million people dependent on domestic wells for drinking water.

Natural resource managers face increasing challenges in dealing with drought. As competition for water increases between its various uses (water supply, energy demands, ecological services, recreation, and other environmental and ecological needs), our ability to forecast the onset and termination of drought becomes ever more important.

This video captures both the resident and anadromous forms of (Oncorhyncus mykiss) Rainbow Trout in a small tributary in the upper Cowlitz River Basin, Washington during spawning season. The male Rainbow Trout exhibits a courting behavior as it quivers against the side of the larger female (HOR) hatchery origin steelhead.

Kathy Conn, a U.S. Geological Survey Water Quality Specialist, demonstrates a new USGS field method using a continuous flow centrifuge to collect suspended sediment from large volumes of water in the Duwamish River near Seattle Washington.
 

This video clip shows the Kamokuna ocean entry, with the laze plume blocking the view of the delta. The billowing white cloud rising from the ocean entry is a corrosive seawater plume laden with hydrochloric acid and fine volcanic particles that can irritate the skin, eyes, and lungs.

Have you ever wondered what all the parts of a satellite do? This video identifies a few of the main components onboard Landsat 8 and tells you about their role in flying the satellite and capturing images of the Earth's surface below. Learn more about USGS Landsat.

The USGS Texas Water Science Center has developed a new mobile application called “Water On-the-Go” that gives people easy access to current conditions in streams across Texas. The information reflects what is happening in streams near you at that very moment.
