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.

Elevated CO2 Facility, WARC, Lafayette, LA, USA
Date Published: April 8, 2016

Wetlands have the potential to absorb large amounts of carbon dioxide via photosynthesis, and flooded soils have low oxygen levels which decrease rates of decomposition to promote the retention of soil carbon. However, the type of greenhouse gases emitted from wetlands varies by wetland type and soil condition. A suite of approaches are being used to assess  fluxes of greenhouses gases, like...

USGS investigates the eco-physiological responses of coastal forested wetland vegetation to envrionmental stressors, and what role vegetation may have in affecting local hydrological cycling as a result of these stressors.

Date Published: April 8, 2016

As tidal freshwater forested wetlands - TFFWs - are influenced by salinty due to salt water intrusion, they may experience changes in plant community composition, growth, and productivity. Models are needed to predict vegetation community change or dieback, as well as changes in carbon sequestration and storage due to changing climate, drought, changes in freshwater discharge, elevated carbon...

Sampit River, SC, USA
Date Published: April 8, 2016

Tidal freshwater forested wetlands - TFFWs - can be found in the upper intertidal areas of many estuaries and act as a transition between coastal marshes and bottomland hardwood wetlands. However, it is because of their location that makes them vulnerable to sea-level rise, and they are constantly transitioning to different wetland types. USGS addresses how various processes are affected in...

Tidally Influenced Freshwater Forested Wetlands
Date Published: April 8, 2016

Wetlands in river deltas - like the Mississippi River Delta Plain - may be more vulnerable to sea-level rise. Historically, coastal wetlands responded to these changes by increasing surface elevation or migrating up-slope. USGS conducts research to identify the biogeochemical influences on sediment addition in coastal wetland areas. 

Controlled greenhouse experiments manipulating the marsh elevation and flood duration
Date Published: April 8, 2016

Sudden Marsh Dieback - SMD - has been documented for the past two decades throughout coastal areas of the United States. With these large-scale diebacks comes the loss of ecosystem functions and services. USGS scientsts use field work and greenhouse studies to investigate the factors that control the resilience and resistance of coastal salt marshes to SMD.

Coastline degradation as an indicator of global change

Finding a climate change signal on coasts is more problematic than often assumed. Coasts undergo natural dynamics at many scales, with erosion and recovery in response to climate variability such as El Niño, or extreme events such as storms and infrequent tsunamis. Additionally, humans have had enormous impacts on most coasts, overshadowing...

Late Cenozoic geology and lacustrine history of Searles Valley, Inyo and San Bernardino Counties, California

Searles Valley is an arid, closed basin lying 70 km east of the south end of the Sierra Nevada, California. It is bounded on the east and northeast by the Slate Range, on the west by the Argus Range and Spangler Hills, and on the south by the Lava Mountains; Searles (dry) Lake occupies the north-central part of the valley. During those parts of...

Modeling and dynamic monitoring of ecosystem performance in the Yukon River Basin

Central Alaska is ecologically sensitive and experiencing stress in response to marked regional warming. Resource managers would benefit from an improved ability to monitor ecosystem processes in response to climate change, fire, insect damage, and management policies and to predict responses to future climate scenarios. We have developed a method...

Coastal-change and glaciological map of the Trinity Peninsula area and south Shetland Islands, Antarctica: 1843-2001: Chapter A in Coastal-change and glaciological maps of Antarctica

Changes in the area and volume of polar ice sheets are intricately linked to changes in global climate, and the resulting changes in sea level could severely impact the densely populated coastal regions on Earth. Melting of the West Antarctic part alone of the Antarctic ice sheet would cause a sea-level rise of approximately 6 meters (m). The...
