Lacy, J.R., Carlson, E.M., and Ferreira, J.C.T., 2016, Wind-wave and sediment-transport time-series data from Liberty Island and Little Holland Tract, Sacramento-San Joaquin Delta, California, 2015-2017 (ver. 2.0, September 2019): U.S. Geological Survey data release,


Water depth and turbidity time-series data were collected in Little Holland Tract (LHT) from 2015 to 2017. Depth (from pressure) was measured in high-frequency (6 or 8 Hz) bursts. Burst means represent tidal stage, and burst data can be used to determine wave height and period. The turbidity sensors were calibrated to suspended-sediment concentration measured in water samples collected on site. The calibration and fit parameters for all of the turbidity sensors used in the study are tabulated and provided with the data. Data were sequentially added to this data release as they were collected and post-processed. Typically, each zip folder for a deployment period contains one file from an optical backscatter sensor and two files [...]

These data will be used to determine the range of turbidity and suspended-sediment concentration (SSC) in Little Holland Tract and the extent to which wind waves contribute to turbidity, to investigate physical attributes of flooded habitats that promote enhanced turbidity, and to evaluate the potential for flooded agricultural tracts to contribute to elevated turbidity in adjacent waters.
