Marsh elevation, relative to sea level, is maintained by both organic material and the deposition of inorganic sediment. Additionally, horizontal marsh extent is altered by lateral erosion and accretion. In wetlands within and near Grand Bay National Estuarine Research Reserve, parts of the salt marsh are eroding relatively rapidly. To understand the connection between sediment fluxes and these processes, the U.S. Geological Survey made oceanographic and water-quality measurements from August 2, 2016, to January 28, 2017, to quantify suspended-sediment concentration and sediment transport in tidal channels and open embayments in and near Grand Bay National Estuarine Research Reserve. Purpose: These suspended-sediment concentration (SSC) data from water samples collected in Grand Bay, Alabama and Mississippi, from August 2, 2016, to January 28, 2017, supplement oceanographic and water-quality time-series measurements. Specifically, the SSC data are used to estimate the relation between suspended mass and optical turbidity measurements. Supplemental_Information: These data were collected as part of a six-month-long study of flow velocity, sediment transport, waves, and water quality within Grand Bay. The larger study included long-term time-series deployments of oceanographic instrumentation, with the goal of measuring water-column sediment fluxes and relating them to observed shoreline erosion. More information about the field activity during which these data were collected is available at https://cmgds.marine.usgs.gov/fan_info.php?fan=2016-034-FA . More information about the Estuarine Processes, Hazards, and Ecosystems project, which conducted the long-term study, is available at https://www.usgs.gov/centers/whcmsc/science/estuarine-processes-hazards-and-ecosystems .

Difference between first and second weighing were checked for stability and were within +or- 1%. Logical_Consistency_Report: Water samples were collected using a van Dorn sampler, and processed for suspended-sediment concentration(SSC) following USGS methods (Fishman and Friedman, 1989). Water samples were stored in a refrigerated and dark location, and were filtered within one month of collection. The entire volume of each water sample was filtered to avoid sub-sampling errors. Deionized water was put through each filter as the last step of the filtration process to rinse dissolved salts from the filter. Standard laboratory protocols (Fishman and Friedman, 1989) were followed to ensure thorough drying and accurate weighing of samples. Completeness_Report: Dataset is considered complete for the information presented. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Horizontal position was determined using a Garmin GPSMAP 78sc handheld GPS. The expected absolute, horizontal accuracy is stated to be 3 to 5 m at the 95% confidence level using the WAAS setting. Additional sources of error in the position for the water sample locations are caused by the offset from the GPS and the exact location of the van Dorn water sampler at the time the sample was taken, which could be as large as 2 m; therefore overall expected accuracy of the reported horizontal position for these water sample locations is on the order of 7 m or better. One exception is sample 160 where no GPS way point was stored and the horizontal position coordinates were estimated from the samples taken before and after at the GB4 site location; for this sample the position accuracy could be greater than 7 m. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Total water column depth values at each sample site were determined from using a handheld depth sounder. Sample depths were determined by markings on the lowering line for the van Dorn sampler, and the samples were typically between 0.25 and 0.75 m above the seabed. Depths given were taken from the water surface at time of sample, and were not referenced to a fixed datum. Expected accuracy of depth measurements is 0.3 m or better.
