Water depth, turbidity, and current velocity time-series data were collected in Little Holland Tract from 2015 to 2017. Depth (from pressure) and velocity were measured in high-frequency (8 Hz) bursts. Burst means represent tidal stage and currents, and burst data can be used to determine wave height, period, direction, and wave-orbital velocity. 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 a CTD, two files of data from a bursting pressure sensor and two data files from the velocimeter, which includes data from the optical backscatter sensor.
---------
Data were collected from several sites in Little Holland Tract (LHT) and Liberty Island (LI), including the Liberty Island Conservation Bank (LICB), from 2015 to 2017. Table 1 (below) lists the deployment name (DLXXX) and dates for each sampling station location. Station names starting with ‘H’ are in LHT; station names starting with ‘L’ are in LI, and the station name starting with ‘W’ is in LICB. At stations with a ‘W’ as the second character of the station name, we collected water-level, wind-wave, and turbidity time-series data. At stations with a ‘V’ as the second character of the station name, we collected water-level, wind-wave, and turbidity, as well as velocity time-series data. The turbidity sensors were calibrated to suspended-sediment concentration measured in water samples collected on site (tables 2a,b) for LHT and LI. Details on instrumentation and sampling are included on the individual pages for each station (see links below). Data were sequentially added to this data release as they were retrieved and post-processed.
