* These variables are estimated and only computed in quality controlled data files.
TALK_LIAR (Total Alkalinity) is estimated from the LIAR algorithm (Carter et al., Limnol. Oceanogr.: Methods 16, 2018, 119–131).
DIC (Dissolved Inorganic Carbon) and pCO2 (CO2 partial pressure at in situ conditions) are
computed from pH and TALK_LIAR using carbon dioxide equilibrium constants (Williams et al.,
Global Biogeochem. Cycles, 31, doi:10.1002/2016GB005541).
** POC (Particulate Organic Carbon) is computed from optical backscatter (b_bp) using the
algorithm in Johnson et al. (J. Geophys. Res. Oceans, 122, doi:10.1002/2017JC012838) in the QC file.
****Only one float Apex 21291, WMO 5907061 has an FLBBFL sensor with chlorophyll at 470 and 435 nm
++Float 21146, WMO 7901106 is a 6 sensor float that includes downwelling irradiance
