The Porsuk River floodplain near Eskisehir, Turkey contains a large number of wetlands, which have been managed by humans for millennia.
This study will examine the potential effects of climate-change-induced sea level rise, drought and water extraction by examining tree growth patterns across the Gulf Coast, specifically targeting long-term research plots available in the North American Baldcypress Swamp Network (NABCSN) and the Suwannee River.
Modeling both potential changes in climate and responses of species and habitats can increase certainty in management decisions by helping managers to understand the range of possible species and habitat responses under different alternative futures. Climate envelope modeling is one type of modeling that can be useful in understanding species and habitat responses to climate change...
Peninsular Florida is one of the most vulnerable regions to climate change in the United States. With complex socioeconomic and ecology dynamics and a large number of governing agencies involved in conservation planning, USGS worked to created an appropriate framework for landscape conservation cooperative-scale decision-making across current conservation planning agencies and jurisdictions....
Severe coral bleaching in 2005, followed by a disease outbreak, resulted in severe reef degradation in the US Virgin Islands; the amount of living coral cover at long-term monitoring sites decreased an average of 60%. With climate change, high seawater temperatures are expected to lead to more frequent bleaching episodes and possibly more disease outbreaks. ...
At the global-scale, macroclimatic drivers govern ecosystem structure and function in tidal saline wetlands (e.g., salt marshes, mangrove forests, salt flats). However, global reviews and models for these ecosystems typically do not directly include climatic drivers. The objective of this research is to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure...
Extreme drought and temperature in the southeastern United States may become more frequent in the future, and any extreme shifts in climate condition are likely to have effects on wetland ecosystem function. USGS research predicts the effects of climate change by shifts in function and biodiversity across existing climate gradients in baldcypress swamps. ...
USGS aims to integrate biological and hydrological models to help develop management tools to deal with the projected ecological consequences of rising sea level in coastal south Florida....
Mangrove forests have migrated inland over the past few decades at many locations along the northern Gulf of Mexico coast. This expansion has been attributed to factors associated with climate change, such as increased salinity resulting from sea-level rise and longer intervals between winter freezes, which can kill cold-intolerant mangrove species. ...
The USGS National UAS Project Office supports the safe, efficient, and cost-effective adoption of UAS technology into the research and operational activities of the DOI.
Science projects are the backbone of the NCCWSC and CSCs. Our projects are based on the needs of our partners, including land managers, natural/cultural resource managers, tribal and indigenous communities. Our research is complemented by our other efforts that include training the next generation of scientists and conducting national synthesis projects that cross CSC boundaries.
Risk and vulnerability studies that seek to improve the scientific basis for assessments and develop quantitative, qualitative, geospatial decision support tools that characterize and communicate the vulnerability of both human communities and natural ecosystems.
Evidence for an ice shelf covering the central Arctic Ocean during the penultimate glaciation
The hypothesis of a km-thick ice shelf covering the entire Arctic Ocean during peak glacial conditions was proposed nearly half a century ago. Floating ice shelves preserve few direct traces after their disappearance, making reconstructions difficult. Seafloor imprints of ice shelves should, however, exist where ice grounded along their flow paths...Jakobsson, M., Nilsson, J., Anderson, L., Backman, J., Björk, G., Cronin, T.M., Kirchner, N., Koshurnikov, A., Mayer, L., Noormets, R., O’Regan, M., Stranne, C., Ananiev, R., Macho, N.B., Cherniykh, D., Coxall, H., Eriksson, B., Flodén, T., Gemery, L., Gustafsson, O., Jerram, K., Johansson, K., Khortov, A., Mohammad, R., and Semiletov, I.
Evaluating Coastal Landscape Response to Sea-Level Rise in the Northeastern United States—Approach and Methods
The U.S. Geological Survey is examining effects of future sea-level rise on the coastal landscape from Maine to Virginia by producing spatially explicit, probabilistic predictions using sea-level projections, vertical land movement rates (due to isostacy), elevation data, and land-cover data. Sea-level-rise scenarios used as model inputs are...Erika E. Lentz, Sawyer R. Stippa, E. Robert Thieler, Nathaniel G. Plant, Dean B. Gesch, and Radley M. Horton
Summarizing components of U.S. Department of the Interior vulnerability assessments to focus climate adaptation planning
A secretarial order identified climate adaptation as a critical performance objective for future management of U.S. Department of the Interior (DOI) lands and resources in response to global change. Vulnerability assessments can inform climate adaptation planning by providing insight into what natural resources are most at risk and why. Three...Thompson, Laura M.; Staudinger, Michelle D.; Carter, Shawn L.
Vulnerabilities and opportunities at the nexus of electricity, water and climate
The articles in this special issue examine the critical nexus of electricity, water, and climate, emphasizing connections among resources; the prospect of increasing vulnerabilities of water resources and electricity generation in a changing climate; and the opportunities for research to inform integrated energy and water policy and management...Frumhoff, Peter; Burkett, Virginia; Jackson, Robert B.; Newmark, Robin; Overpeck, Jonathan; Webber, Michael
Effects of antecedent hydrologic conditions, time dependence, and climate cycles on the suspended sediment load of the Salinas River, California
Previous estimations of sediment flux for the Salinas River of central California were based on data collected in the 1970s and assumptions of time invariant suspended sediment–discharge behavior. The goals of this study were to estimate sediment flux from the Salinas River using data from 1967–2011 by incorporating time dependent behavior and...Andrew B. Gray, Gregory B.

Climate change and wildfire risk in an expanding wildland–urban interface: a case study from the Colorado Front Range Corridor
We projected the spatial pattern of the WUI and its associated wildfire risk from 2005 to 2050 at 90-m spatial resolution and 5-year intervals in Colorado Front Range using CHANGE, a landscape change model that simulates land cover and land use change, natural vegetation dynamics, and wildfire in a unified framework. A total of four scenarios from...Zhihua Liu, Michael C. Wimberly, Aashis Lamsal, Terry L. Sohl, Todd J. Hawbaker
Quantitative attribution of major driving forces on soil organic carbon dynamics
Soil organic carbon (SOC) storage plays a major role in the global carbon cycle and is affected by many factors including land use/management changes (e.g., biofuel production-oriented changes). However, the contributions of various factors to SOC changes are not well understood and quantified. This study was designed to investigate the impacts of...Wu, Y., Liu, S., and Tan, Z.
Trend analyses with river sediment rating curves
Sediment rating curves, which are fitted relationships between river discharge (Q) and suspended-sediment concentration (C), are commonly used to assess patterns and trends in river water quality. In many of these studies, it is assumed that rating curves have a power-law form (i.e. C = aQb, where a and b are fitted parameters). Two fundamental...Jonathan A. Warrick
