Mission Areas L2 Landing Page Tabs
Climate and Land Use science is essential to improve understanding of past and present change; develop relevant forecasts; and identify those lands, resources, and communities most vulnerable to Earth system change processes.Our Science Strategy
Significant damage to coastal communities and surrounding wetlands of the north Atlantic states was caused by Hurricane Sandy in late October 2012, mostly tied to an associated storm surge of record extent and impact.
Information Science staff help the National Office of the National Climate Change and Wildlife Science Centers and individual Climate Science Centers with a variety of project and data management activities, including storing, managing, and distributing datasets; building and maintaining metadata; discovering datasets; and delivering their data and metadata as web services through various...
USGS is committed to meeting the science needs of four Native American Tribes impacted by Hurricane Sandy in New England and New York: the Wampanoag Tribe of Gay Head - Aquinnah on Martha’s Vineyard, MA; the Mashpee Wampanoag Tribe on Cape Cod, MA; the Narragansett Indian Tribe near Charlestown, RI; and the Shinnecock Indian Nation on Long Island.
This project will create a Climate Change Adaptation Plan for the Chitimacha Tribe of Louisiana (Chitimacha), serving as an implementable plan for coastal community adaptation to climate change that can be used as a model in other small communities.
The interior marshes of the Ten Thousand Islands National Wildlife Refuge (TTINWR) are currently negatively impacted by sea level rise through saltwater intrusion from the south which furthers mangrove encroachment into the freshwater marsh.
As Greater Everglades restoration project implementation progresses, wetlands in near coastal areas may undergo changes in salinity, hydroperiod, and water depth.
Field observations over recent decades have confirmed mangrove expansion landward in tropical zones and poleward in temperate saltmarsh settings around the northern Gulf of Mexico.
Storm surge waves and tides of hurricanes have the propensity to wash up marsh detritus of dead reeds and leaf debris along with plastic trash and lumber, commonly referred to as wrack, from overwashed beaches, marshes, forests, streets, and lawns.
As custodians of ecological goods and services valued by society, coastal National Wildlife Refuges (NWRs) have an especially important role to play in helping socio-ecological systems adapt to global-change processes.
Climate change is widely acknowledged to be having a profound effect on the biosphere with many and diverse impacts on global resources. Mountain ecosystems in the western U.S. and the Northern Rockies in particular are highly sensitive to climate change. In fact, the higher elevations of the Northern Rockies have experienced three times the global average temperature increase over the past...
The science of dating growth rings and history of live and fossil wood samples is called dendrochronology. This technique is valuable for conducting climate reconstructions where meteorological data is lacking and for detecting past disturbance events such as tropical storms and hurricanes.
As tropical storms and hurricanes move onshore and make landfall, wind and storm surge can be sufficiently high to damage built-infrastructure and natural systems, most notably coastal forests at the interface of land and sea.
