The extent of Hurricane Sandy’s wrath — and the future coastal vulnerability of the region — is clear in a new U.S. Geological Survey analysis of recently collected lidar coastal data. The research documented particularly dramatic impacts within the Fire Island National Seashore on Long Island, NY.

Groundwater in Virginia is a greater contributor to streamflow than calculated by the most commonly used technique, according to recent USGS research. For decades, hydrologists have used only the changing water levels and flow rates, a graphical hydrograph separation or GHS method, in streams to try to estimate the base-flow component. However, many individual studies during

Groundwater provides drinking water for millions of Americans and is the primary source of water to irrigate cropland in many of the nations most productive agricultural settings. Although the benefits of groundwater development are many, groundwater pumping can reduce the flow of water in connected streams and rivers—a process called streamflow depletion by wells. The USGS

As recovery efforts for those impacted by Hurricane Sandy continue, U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane. This sampling effort is part of the federal government’s broad efforts to ensure public health and to support the state, tribal, and local response

The higher river flows following Hurricane Sandy will bring an increased amount of nutrient and sediment to the Chesapeake Bay; however these amounts will not approach the nutrient and sediment loads seen in 2011 from Hurricane Irene and Tropical Storm Lee, according to preliminary data released by the U.S. Geological Survey.

On Oct. 29, 2012, USGS revised its forecasts for coastal change due to Hurricane Sandy. Now, the forecasts are as follows: Delmarva Peninsula: 91 percent of the beaches are expected to experience erosion; 55 percent of the beaches are expected to experience overwash, and 22 percent are expected to experience inundation. Coastal New Jersey: 98

Nearly three quarters of the coast along the Delmarva Peninsula is very likely to experience beach and dune erosion as Hurricane Sandy makes landfall, while overwash is expected along nearly half of the shoreline.

Storm response crews from the U.S. Geological Survey are installing more than 150 storm-tide sensors at key locations along the Atlantic Coast — from the Chesapeake Bay to Massachusetts — in advance of the arrival of Tropical Storm Sandy.

The most deadly type of malaria in humans and the one most prevalent in Africa is one that is very sensitive to climate. Previously published scientific studies put the optimal temperature for malaria transmission from mosquitos to humans at 31 degrees C (88 degrees F), but according to a new mathematical model, the temperature for peak

Landsat satellites have witnessed over four decades of changes on Earth. In advance of the next Landsat spacecraft launch, the Landsat Data Continuity Mission, the U.S. Geological Survey (USGS), in cooperation with the National Aeronautics and Space Administration (NASA), announces the selection of the Landsat Science Team. This expert team of scientists and engineers will serve
