Dataset: Intertidal mooring chlorophyll-a

All fluorometry data and tidal height predictions are collected and processed in Coordinated Universal Time (UTC). Out of water measurements are flagged in the dataset by interpolating between the raw fluorescence data points in order to align the fluorescence time series with tidal height predictions (downloaded from: http://tbone.biol.sc.edu/tide/) and identify observations when the tide is < 1 m above the apparent tidal height of the fluorometer. The apparent tidal height of the fluorometer is determined by visual inspection of the plotted fluorescence and tidal height data. The focal period is during extreme low tides when the fluorometer is clearly out of water, recorded measurement are close to the dark count offset value (see below) and do not change over the low tide interval. These data delineate an obvious, sharp transition as the instrument is uncovered or covered by the tide.  Instrument “fouling” is also flagged in the dataset by visual inspection of the plotted fluorescence data.  Fouling is defined as any period of randomly scattered data without an obvious trend in the fluorescence signal.
