In this webinar, data and publications will be presented describing the results of research identifying potential changes to estuaries in the Pacific Northwest due to different climate change stressors.

]]> http://gallery.usgs.gov/videos/575 This time-lapse video shows the dramatic natural tidal cycles of a salt marsh in San Francisco Bay -- daily rhythms to which animals take refuge in high ground, and the marsh receives sediment and nutrients from the estuary. But what will happen to these marsh ecosystems under sea level rise scenarios? Will we see shifts in vegetation and animal species, or lose some marsh ecosystems altogether? USGS scientists are surveying Pacific Coast marshes to model sea level rise scenarios for the next 100 years -- helping coastal planners visualize the threats to marsh habitat under current conditions, and work towards long-term management strategies.

Or will the marsh be completely inundated? USGS scientists are conducting extensive elevation and habitat surveys along the U.S. Pacific Coast, and using the data to model sea level rise impact for the next 100 years. This research will help coastal planners visualize the threats to marsh habitat under current conditions, and work towards long-term management strategies.

Dark blue represents mean high water level, light blue is mean sea level. The marsh platform is accreting a constant 1.9 mm/yr, sea level rises 0.4 m by 2050 and 1.0 meter by 2100.

]]> http://gallery.usgs.gov/videos/468 This video describes how scientists study past changes in sea-level and coastal environments by analyzing mangrove peat. Mangrove islands located off the coast of Belize are underlain by deep deposits of peat (organic soil), which retain a record of past sea level, vegetation, and climate. By studying past changes in sea level and how intertidal ecosystems, such as mangroves, have responded to these changes, we can better predict what will happen in the future as sea levels increase. The information generated by such research is critical to geophysical modeling efforts as well as to management and conservation of coastal ecosystems.

]]> http://gallery.usgs.gov/videos/432 The Mekong is one of the world's great rivers cascading through six Asian countries from the Tibetan Plateau to the South China Sea, connecting China, Myanmar, Laos, Thailand, Cambodia and Vietnam. How one country uses or changes the waters of the Mekong upstream can have important implications for the health of the river and people downstream. Increasing demands for hydropower and irrigation have prompted several countries to plan the construction of dams on the Mekong River and its tributaries. The cumulative effects of such dams can be quantified through the use of hydrologic data and computer models. Visualization tools can help people develop a shared understanding of river resources and provide a science basis for critical decisions about regional development and sustainability. The U.S. Department of State in cooperation with the U.S. Geological Survey and university partners are developing visualization tools to help policy makers and planners communicate and evaluate complex river issues. The video is a form of science diplomacy requested by the U.S. Department of State to educate policy-makers and citizens in Southeast Asia about the vital importance of the Mekong river and delta in maintaining food security and livelihoods in the region. The six nations that share the Mekong River will all benefit from a commonly-held understanding of the benefits, trade-offs, and impacts of water resource development. Scientific visualization provides a powerful tool for improving future planning and harmonizing the development of the Mekong for people, fish, and wildlife.

]]> http://gallery.usgs.gov/videos/369 USGS scientists from the Pacific Coastal and Marine Science Center explore how sediment moves across San Francisco Bay tidal flats.  The research team deploys a suite of large instrumented tripods to record sediment movements over a six-week period in early 2011.  Answers from this work will help determine whether deposition of sediment at high tide is occurring quickly enough to preserve marshes in the face of sea-level rise.  

The program also highlights the value and function of the USGS Mendenhall Fellowship Program.   The Mendenhall Program at the USGS provides recent PhD graduates an opportunity to conduct cutting-edge research on pressing scientific questions with the guidance and mentoring of established scientists.

]]> http://gallery.usgs.gov/videos/347 This video describes causes of wetland loss in the Mississippi River Delta. Rapid land subsidence due to sediment compaction and dewatering increases the rate of submergence in this deltaic system.  The construction of levees along the lower Mississippi River also has reduced delivery of sediments to coastal wetlands, which have been deteriorating as soil surfaces sink and wetland plants are subjected to excessive flooding.  Other factors that have contributed to land loss include construction of canals and periodic hurricanes. Sea-level rise can lead to movement of saltwater inland, but coastal plants tolerate salinity through several morphological and physiological mechanisms. The causes of wetland loss are complex and not the result of any single factor.  Natural and anthropogenic factors have combined with global processes such as sea level rise to cause wetland loss in the Mississippi River Delta.
