Time-series measurements of oceanographic and water quality data collected in the Herring River, Wellfleet, Massachusetts, USA, November 2018 to November 2019

Restoration in the tidally restricted Herring River Estuary in Wellfleet, MA benefits from understanding pre-restoration sediment transport conditions. Submerged sensors were deployed at four sites landward and seaward of the Herring River restriction to measure water velocity, water quality, water level, waves, and seabed elevation. These data will be used to evaluate sediment dynamics and geomorphic change and inform marsh modeling efforts over tidal and seasonal timescales. Submerged sensors were deployed to collect a time series of water level, velocity, pressure, waves, seabed elevation, turbidity, pH, fluorescent dissolved organic matter (fDOM), chlorophyll, dissolved oxygen, blue-green algae, conductivity, and temperature data. These data were collected as part of a larger study, funded by the USGS-NPS Natural Resource Preservation Program (NRPP), of four sites within the Northeast Coastal and Barrier Network: Cape Cod National Seashore, Fire Island National Seashore, Gateway National Recreation Area, and Assateague Island National Seashore. The overarching goals of this study are to identify the dominant sources of sediment, determine how sediment transport varies over time, and analyze sediment availability to the marshes in order to inform management efforts
