ancillary_variables :: raw_signal_cdom
comment :: Fluorometric CDOM Concentration is a measure of how much light has been re-emitted (fluoresced) from colored organic compounds found in the colored dissolved organic matter (CDOM) in seawater. Examples of CDOM include tannins (polyphenols that bind to proteins and other large molecules) or lignins (polymers of phenolic acids) from decaying plant material and byproducts from the decomposition of animals. It accounts for the tea-like color in seawater. CDOM is not particulate, but seawater can contain both CDOM and turbidity.

(time)

float64

dask.array<chunksize=(13106200,), meta=np.ndarray>

ancillary_variables :: raw_signal_chl
comment :: Fluorometric Chlorophyll-a Concentration is an estimate of phytoplankton biomass using fluorescence. The fluorometer emits light at a specific wavelength that is absorbed by chlorophyll and re-emitted as light at a different wavelength. By measuring the intensity of the re-emitted wavelength of light the chlorophyll-a concentration in the surrounding seawater can be estimated. Chlorophyll-a concentrations can be used as a proxy for phytoplankton biomass as it is a dominant photosynthetic pigment.

comment :: Seawater Pressure refers to the pressure exerted on a sensor in situ by the weight of the column of seawater above it. It is calculated by subtracting one standard atmosphere from the absolute pressure at the sensor to remove the weight of the atmosphere on top of the water column. The pressure at a sensor in situ provides a metric of the depth of that sensor.
