Unusual Sources of Tsunamis - From Krakatoa to Monterey Bay
by Eric Geist, USGS Research Geophysicist
- Not all tsunamis are generated by earthquakes
- Tsunamis can be caused by volcanoes, landslides, and even atmospheric disturbances
- Data from tide gauges can help unravel the complex physics of these sources
Geology Up-Close: Big answers from small scale observations
by Leslie Hayden-USGS Geologist, Diane Moore-USGS Geologist, Kathryn Watts-USGS Research Geologist, Marjorie Schulz-USGS Research Hydrologist, and Laura Stern-USGS Research Geophysicist
- How does a scanning electron microscope (SEM) work?
- What does USGS study with the SEM? Earthquakes, Volcanoes, Mineral and energy resources, Soil and aquifer processes
Brown Bears, Sea Otters, and Seals, Oh My!: Unexpected interactions on the Katmai Coast
by Grant Hilderbrand, Chief of the Marine Ecosystems Office
- Highlights of ongoing research on brown bears on the coast of the Katmai National Park
- Observations from video collars deployed on brown bears
- Implications for population health and species adaptability
Potential Corrosivity of Untreated Groundwater in the United States
by Kenneth Belitz, Chief, Groundwater Assessment, National Water-Quality Assessment Project
- 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.
Underwater Secrets of the Hayward Fault Zone: Integrated 3D imaging to understand earthquake hazards
by Janet Watt, USGS Research Geophysicist
- Underwater imaging provides a unique opportunity to study urban fault hazards.
- How do we link surface structures to depths where earthquakes occur?
- How does "acoustic trenching" help us understand earthquake history?
The Effects of Climate Change: A Scientific Pathway Forward
by Tom Suchanek, USGS (Scientist Emeritus) Western Ecological Research Center, and
UC Davis (Research Associate) Bodega Marine Lab and Dept. of Wildlife, Fish & Conservation Biology
- The frequency of extreme and unpredictable weather events is increasing.
- What are the effects of an increase or decrease in carbon emissions?
- What is scientific research projecting for the future of climate change?
Warm Ice - The Dynamics of Rapidly Changing Glaciers
by Bruce F. Molnia, USGS Physical Scientist
- Glacier Numerology -- The how big, how long, how thick, how much, how often, of glacier science.
- Glacier Photography -- While a picture may be worth a thousand words, a collection of images may tell a complete forensic story.
- Glacier Geophysics -- How new technologies are being introduced to reexamine and refine decades old glacier analyses.
Roving on Mars: Curiosity's exploration of Gale Crater
by Lauren Edgar, USGS Research Geologist
- Overview of the Mars Science Laboratory Mission
- Highlights from 5 years of exploring sedimentary environments
- Preview of next steps in Curiosity's climb up Aeolis Mons
What's in a species Name?: How wildlife management relies on modern systematics research and museum collections
by John B. French, Jr., Center Director USGS Patuxent Wildlife Research Center
- What have museum collections taught us about invasive diseases?
- When is an endangered species not a species?
- How can birds in a museum help protect airline passengers?
- How do geology and biology govern what species we find on the Channel Islands?
Global Trends in Mineral Commodity Supplies?
by Steven M. Fortier, Director of the USGS National Minerals Information Center
- The U.S. is increasingly reliant on supply of mineral raw materials from other countries.
- Advanced technologies are increasingly making use of nearly the entire periodic table of the elements.
- Dynamic studies of critical and strategic mineral supply and demand can identify emerging potential supply risks.
- The USGS - National Minerals Information Center has assumed a leading role in mineral criticality studies.
