Data to support carbon (C) budget assessment of tidal freshwater forested wetland and oligohaline marsh ecosystems along the Waccamaw and Savannah rivers, U.S.A. This work represents the first estimates of C standing stocks, C mass balance, soil C burial, and lateral C export to aquatic environments in tidal freshwater forested wetlands undergoing transition to oligohaline marsh. First release: 2018 Revised: May 2019 (ver. 2.0)

Forest surveys were conducted in nine 20 m x 25 m study plots, split into 3 representatives each for three forest types in Great Dismal Swamp, VA and NC, USA, December 2015 - February 2018. Trees, saplings, and shrubs were identified to species and measured for estimates of standing stocks. Standing stock data include: tree diameter at breast height (dbh), height, and condition; sapling dbh; shrub diameter at root collar, and height. In each plot, roughly 10 co-dominant trees were equipped with dendrometer bands and measured annually for growth estimates.

Data were collected from coastal wetlands (tidal swamps and marsh) along the Waccamaw and Savannah Rivers in South Carolina and Georgia (See Krauss et al. 2009 for additional details). Data were collected from coastal wetlands (tidal swamps and marsh) along the Waccamaw and Savannah Rivers in South Carolina and Georgia (See Krauss et al. 2009 for additional details). Data collected include water level, porewater salinity (conductivity based), water temperature, and conductivity. First measurements began in 2004 and continued through 2016. Water level data: A network of water level recorders was established in 2004-2006 (forests) and in 2009 (marsh). Continuous hourly data were recorded using vented pressure...

These data represent sap flow measurements from four tree species and were recorded every 30 minutes over several months in 2015. Data were collected from a tidally-influenced freshwater forested wetland at Strawberry Swamp, located on Hobcaw Barony, which is approximately 7 km east of Georgetown, South Carolina, USA.

These data represent net ecosystem exchange of CH4 and CO2 collected using eddy covariance over various time frames. Data were collected from a brackish marsh at Pointe-aux-Chenes State Wildlife Management Area and a tidally influenced freshwater marsh at Salvador State Wildlife Management Area. Both sites were located within the coastal zone of Louisiana, USA.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
