FloatViz 6.0 - Apex/ISUS Data Visualization

ISUS nitrate sensors and Deep-Sea DuraFET pH sensors in Webb Research Apex or Sea-Bird Electronics Navis profiling floats.

What's new? We have changed file name formats from UW serial number to WMO (World Meteorological Organization) number. Click here for a table that maps old UW number to new WMO number.

+ CDOM is only available on Navis floats (*nxxxx)
++ Dual oxygen sensors are currently only available on Apex 5906481 and 5906482
* 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 in the QC file only from optical backscatter (b_bp) using the
algorithm in Johnson et al. (J. Geophys. Res. Oceans, 122, doi:10.1002/2017JC012838).
***Only one float (Navis 0565, WMO 5904672) has backscatter at 532 nm.
