Data are in spreadsheet format. The data was used in conjunction with survey data collected as part of the NOAA RESTORE food web project and data from the State of Louisiana Coastwide Reference Monitoring System (CRMS) to characterize the salinity regime and the marsh flooding regime of the sampling sites. The data from the LSU sondes was used with the data from the CRMS sites to develop an index CRMS station for the project area. Little is known about how river diversions influence the ecological trajectory, food web structure, and function of natural versus created marshes. To address this gap, this project established sites in the West Point a la Hache (WPH) area (Barataria Bay, in Plaquemines Parish, Louisiana), near the WPH siphon which periodically shunts Mississippi River water into the local marshes. Sites were also established in nearby marshes that were restored as part of the Lake Hermitage (LH) Marsh Creation Project, representing an ideal model system to examine how seasonal and spatial shifts in salinity due to river diversions influence species composition and food web structure in both natural and different-aged created marshes. Objectives of the overall project included characterizing species compositions and abundances in multiple trophic levels (microbes to upper trophic level predators) and applying bulk (SIA) and compound-specific stable isotope analysis (CSIA) of amino acids (AA) in producer and consumer tissues to describe and compare the structure and complexity of food webs and reveal aspects of fish residency. The data in this accession were funded by the NOAA RESTORE Science Program under award NA17NOS4510091 to Louisiana State University.

The YSI software calculates salinity (psu) from the measured specific conductivity when the data from the sondes are retrieved.
