Coastal wetlands store more carbon than most ecosystems globally. However, little is known about the mechanisms that control the loss of organic matter in coastal wetlands at the landscape scale, and how sea-level rise will impact this important ecological function.

Above- and belowground production in coastal wetlands are important contributors to carbon accumulation and ecosystem sustainability. As sea level rises, we can expect shifts to more salt-tolerant communities, which may alter these ecosystem functions and services. Although the direct influence of salinity on species-level primary production has been documented, we lack an understanding of the landscape-level response of coastal wetlands to increasing salinity. What are the indirect effects of sea-level rise, i.e. how does primary production vary across a landscape gradient of increasing salinity that incorporates changes in wetland type? We measured above- and belowground production in four wetland types that span...

USGS Science Data Catalog (SDC),
This data release consists of vegetation cover, soil surface elevation (also called vertical land motion of the wetland (VLMw)), and vertical accretion data collected over 23 months beginning in May 2001 in a restored brackish marsh in southeast Louisiana, USA. Vegetation cover was estimated in permanent plots, and soil cores were collected for determination of bulk density, organic matter content and texture. VLMw was measured using rod surface elevation tables, while accretion was measured using feldspar marker horizons (i.e., RSET-MH technique).

USGS Science Data Catalog (SDC),
The sustainability of coastal wetlands largely hinges on their ability to accrue elevation capital at a rate that equals or exceeds relative sea-level rise. A better understanding of these processes is needed to accurately assess the sustainability of these landscapes, and to predict their response to restoration measures such as sediment delivery through river diversions.

[u'Ecology',
Continuous water quality sensor data were collected at USGS 292939089544400 Wilkinson Bayou cutoff north of Wilkinson Bay, LA gage. Field water-quality measurements were collected using a YSI EXO2 water-quality sonde equipped with a data logger to capture hourly data using sensors for measuring water temperature, specific conductance, salinity, pH, oxidation and reduction potential (ORP), fluorescent dissolved organic matter (fDOM), and turbidity. The monitor was housed in an 8-inch diameter polyvinyl chloride (PVC) pipe attached to a temporary wooden structure near the gage. Measurements were collected from a fixed mid-depth point in the water column. All data were collected using U.S. Geological Survey (USGS)...
