Dissolved inorganic carbon (DIC) and total alkalinity (TA) are fundamental components of carbonate systems that control pH and buffering capacity of a water body. Three coastal marshes with contrasting salinities in Barataria Basin, Louisiana, USA, were sampled five times between December 2018 and October 2019 to understand seasonal changes in porewater carbonate chemistry and its impact on surrounding water bodies. Porewater DIC and TA increased with depth irrespective of marsh type and ranged from 4.47 to 31.61 mmol/kg and from 1.78 to 28.56 mmol/kg, respectively. The salt marsh had higher porewater DIC and TA compared to the lower salinity intermediate and brackish marshes, probably due to sulfate reduction in...

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)...
