Hydrodynamic time-series data from San Pablo Bay and Grizzly Bay , California, 2019

Three platforms (Spider tripod, Hawaii tripod, and a surface mooring) were deployed in Grizzly Bay, and together contained the following instruments: RBR DUO bursting pressure sensor, Echologger Altimeter, three RBR CTDs, RBR Vituosos with Seapoint turbidity meter, three Nortek single point acoustic doppler velocimeters each with a Seapoint turbidity meter, Sequoia Scientific Laser In-situ scattering and transmissometry (LISST).

Instruments deployed in San Pablo Bay channel (via top-hat platform). Instruments deployed include: RDInstruments acoustic doppler current profiler and RBR CTD.

Instruments were retrieved from both San Pablo Bay and San Pablo Bay channel. The data from the retrieved instruments were post-processed using manufacturers software packages and USGS matlab codes.

Instruments were retrieved from Grizzly Bay. The data from the retrieved instruments were post-processed using manufacturers software packages and USGS matlab codes.

Data were accumulated into NetCDF files. During post-processing, data collected when instruments were out of the water were removed from the time series. Bad data points identified by 1) the deployment and recovery times, 2) data flagged as erroneous by the manufacturer, 3) amplitude or correlation values outside of predetermined quality thresholds for the velocimeter, were removed. The files include data of intermittent poor quality due to interference by vegetation caught on frames. In a few datasets with persistent vegetative interference the compromised data were removed, as noted in the associated metadata. Turbidity data are raw unless otherwise noted and include high values that may be attributable to vegetation. Use of these data requires careful assessment of data quality. LISST volume concentrations are most accurate when the optical percent transmission is above 30, as light passing through the sample volume is unlikely to be scattered by more than one particle. Low quality LISST data at the end of a few files were removed, however some bad data are still present in the files and therefore judgment should be applied when using them, as with all other data files.

Files were named with a convention that uses a 12- to 15-digit alpha-numeric code. The first three characters for this dataset are all 'ERO' for the experiment name; the fourth and fifth positions represent the calendar year in which the data were collected (19, 2019); the sixth, seventh and eighth characters are an alphanumeric code for the site name (GHT, PCT, etc.); the ninth and tenth characters represent the instrument position on the platform, where 01 is the top-most. Next is a two- or three-character code for the instrument type (vec, Norteks Acoustic Doppler Velocimeter; wh, RDInstrument's acoustic doppler current profile current data; wv, RDInstrument's acoustic doppler current profile wave data; pt, RBRs bursting pressure sensor with temperature; ctd, RBRs CTD; tu, RBRs Virtuoso turbidity logger; ls, Sequoia Scientifics LISST). There are an additional 2 characters for instruments that collect in a bursting pattern to indicate whether the file includes the burst data (-b) or the statistics and/or singular observations of the burst (-s). This indicator is omitted if there is no bursting pattern.
