Porewater chemistry of Louisiana marshes with contrasting salinities and its implications for coastal acidification

Dissolved inorganic carbon (DIC) and total alkalinity (TA) are fundamental components of carbonate systems that control pH and buffering capacity of the receiving water body. Three coastal marshes with contrasting salinities in Barataria Basin, Louisiana, USA, were sampled to understand seasonal changes in porewater carbonate chemistry and its impact on surrounding water bodies. Each...

Water Quality and Habitat Data at Bayou Sauvage National Wildlife Refuge, 2019-2021

This data release includes water quality and habitat data collected at Bayou Sauvage National Wildlife Refuge (BSNWR). Monitoring water quality, water-level changes, and bird-use relationships in BSNWR is important to the long-term sustainability of these aquatic resources for use by visitors and aquatic life in these habitats. This data release includes datasets of continuous and...

High resolution water quality and dissolved carbon data from a coastal Louisiana salt marsh from 2019 to 2022

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)...

Wetland elevation and soil characteristics across Bayou Sauvage National Wildlife Refuge (2020-2021)

The recent completion of the US Army Corps of Engineers (USACE) Hurricane and Storm Damage Risk Reduction System (HSDRRS) for New Orleans has effectively blocked surface water exchange between Bayou Sauvage National Wildlife Refuge (BSNWR) and the surrounding Lake(s) Pontchartrain and Borgne and the Gulf of Mexico to which it was once connected. Monitoring changes in hydrology, water...

Coastal Acidification Monitoring in Long Island Sound

Understanding coastal acidification, as it varies from open ocean acidification, is crucial to identifying the unique problems occurring in coastal ecosystems such as Long Island Sound (LIS). The U.S. Geological Survey (USGS) is monitoring water quality parameters throughout LIS and its embayments to evaluate the status and trends of acidification processes in these waters. This project will...
