How will sea level rise impact coastal ecosystems like salt marshes? Will plant species change and shift available habitat for local wildlife? 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. Learn more at the San Francisco Bay Sea Level Rise Project website.
This animation depicts projected sea-level rise at Fagan Slough Marsh. 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.

US Topo is the next generation of topo¬graphic maps from the U.S. Geological Survey (USGS). Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known. In contrast to paper-based maps, US Topo maps provide modern technical advantages that support faster, wider public distribution and enable basic, on-screen geographic analysis for all users.
US Topo maps are available free on the Web. Each map quadrangle is con¬structed in GeoPDF® format from key layers of geographic data (orthoimagery, roads, geographic names, topographic con¬tours, and hydrographic features) found in The National Map.
US Topo quadrangles can be printed from personal computers or plotters as complete, full-sized, maps or in custom¬ized sections, in a user-desired specific format. Paper copies o...

The National Elevation Dataset (NED) is the primary elevation data product produced and distributed by the USGS National 3D Elevation Program (3DEP). The NED provides seamless raster elevation data of the conterminous United States, Alaska, Hawaii, and the island territories. The NED is derived from diverse source data sets that are processed to a specification with a consistent resolution, coordinate system, elevation units, and horizontal and vertical datums. The NED is the logical result of the maturation of the long-standing USGS elevation program, which for many years concentrated on production of topographic map quadrangle-based digital elevation models. The NED serves as the elevation layer of The National Map, and provides basic elevation information for earth science studies and mapping applications in the United States.
The NED is a multi-resolution dataset that is updated bimonthly to integrate newly available,...

The St. Clair River, Lake St. Clair and the Detroit River, also known as the Huron-Erie Corridor, are the international waters that connect Lake Huron to Lake Erie. Environmental changes in the Corridor over time have resulted in a loss of habitat for fish and other organisms. This video is focusing on the successful St. Clair River fish habitat restoration project and the science and collaboration that made it a success!
The Huron-Erie Corridor is the epicenter of fish populations and fish habitat restoration in the Central Great Lakes. The fish spawning habitat restoration successes in these connecting channels can have positive impacts on Lakes Erie and Huron as well as the entire Great Lakes basin.

This female Burmese python broke the records for her length -- 17 feet, 7 inches -- and the number of eggs she contained: 87. She was first captured in Everglades National Park by USGS researchers in the spring of 2012, when they followed a "Judas snake" -- a male python with a transmitter -- and found her nearby in the bushes. USGS scientists then outfitted her with two radio transmitters, a GPS device, and a motion-sensing device before releasing her back into the wild. The second radio transmitter was a failsafe, ensuring she wouldn't "go wild" again. The snake remained in the wild for 38 days and then was removed and euthanized. The information from this snake's every move -- each pitch, roll, and yawl -- was recorded by the motion detector, allowing biologists to piece together her behaviors, including her kills. Biologists plan to use detailed information about the snake's biology a...

The 2011 Mississippi River flood was among the largest and most damaging to occur along this waterway in the past century. This major flood event dramatically increased the flow of water and sediment down the main channel of the Mississippi River and its tributary, the Atchafalaya River. To alleviate pressure on the levee system and control structures, water and sediment were diverted from the river into swamps and marshes in the Atchafalaya basin and Lake Pontchartrain. In contrast to negative impacts to human communities, the flood potentially delivered nourishing sediment to wetlands in the Mississippi River delta plain. This video follows one group of scientists as they investigate sediment deposition in the wetlands of the Mississippi River delta plain. The results of this investigation will lead to a better understanding of how extreme flood events influence sedimentation in wetlands and also will inform efforts to restore the det...

This video describes how scientists are studying freshwater wetlands on the North Island of New Zealand and how nutrients from pasture runoff may alter the vegetation and peat formation in these important ecosystems. Much of what is known about wetlands comes from research conducted in the Northern Hemisphere. In contrast, much less is known about wetland ecosystems in the Southern Hemisphere. Because New Zealand has been geographically isolated, it has unique species of plants and animals found nowhere else. Scientists from the U.S. Geological Survey are collaborating with counterparts in New Zealand to study nutrient effects on plant production and decomposition processes. The peat-forming plants in freshwater wetlands are identified and methods used to study effects of nutrients on peat formation are illustrated. By studying how nutrients affect wetlands in New Zealand, scientists will gain a much broader understanding of how eutr...

This video provides a visual example of how airborne LiDAR (Light D
etection And Ranging) imagery penetrates dense forest cover to reveal
an active fault line not detectable with conventional aerial
photography. The video shows an aerial perspective of the range front
Mt. Tallac fault, which is one of five active faults that traverse
the base of the steep mountains west of Lake Tahoe, California. The
USGS has recently published a report in the Bulletin of the
Geological Society of America that details the seismic hazards of the
Tahoe -Sierra frontal fault zone mapped with the new technology.

Virtual fly-through of San Francisco Bay revealing the seafloor as if the water was drained from the Bay. The movie flies through the south and central Bay, pausing over prominent seafloor features including, large sand waves, rock pinnacles, current scour pits, as well as many human impacts on the seafloor.

Geologists rely on information from deep beneath the Earth's surface to reconstruct the past. As sediments accumulate over time, they create records geologists use to understand Earth history and to predict future processes and trends. The most common way to get this information is to drill a hole in the Earth where sediments have been deposited over time. The type of drilling tool used for cores depends on how deep and how hard the sediments are. Vibracoring is one of the tools used in shallow coastal areas where sediments consist of soft sand and mud. This video podcast describes how cores are collected in shallow water from the deck of a research vessel using vibracoring. The sediments drilled are recovered in the form of a core that will contain an intact record of the past. Core samples are used to assess the geologic history of an area, such as its geomorphology; coastal, marine, and terrestrial processes; and changes in environment...
