//"IceEvRec" = 1 indicates that the float was unable to surface as a result of the ice-avoidance algorithm. Note that this result does not necessarily signify the presence of sea-ice.
//"IceEvRec" = 0 indicates that the float was able to surface as a result of the ice-avoidance algorithm (and/or the absence of ice-avoidance algorithm software, ie for low-latitude floats)
//For more information on the technical aspects of the ice-avoidance algorithm onboard profiling floats, please see Riser et al (2018) https://doi.org/10.1002/2017JC013419

//SPECIAL NOTICE:
//The pressure response for the pH sensor on this NAVIS float was not adequately described for shallow water.
//New coefficients were estimated by first propagating 175-150m average pH values to the surface (0690.023.msg) and then back
//calculating the pressure response (E0TP - E0T). The upper 150m pressure response was then fit to a 4th order polynomial. This
//polynomial was used for pH measurements above this depth and the factory calibration was used for samples below this depth

//NOTE ON CO2SYS CARBONATE SYSTEM CALCULATIONS:
//All carbonate system variables calculated with CO2SYS for Matlab
//(Sharp et al., 2020; see also Lewis and Wallace 1998)
//used the following conditions: pH was reported on the total scale.
//K1 and K2 dissociation constants were from Lueker et al., 2000, doi:
//10.1016/S0304-4203(00)00022-0. The KSO4 dissociation constant was
//from Dickson, 1990, doi: 10.1016/0021-9614(90)90074-Z. The KF dissociation
//constant was from Perez and Fraga 1987, doi: 10.1016/0304-4203(87)90036-3.
//The borate to salinity ratio was from Lee et al., 2010,
//doi:10.1016/j.gca.2009.12.027. Silicate and Phosphate were not
//measured by the float, but estimates based on Redfieldian ratios improved
//the carbonate system estimates. If a nitrate value was considered to
//be of good quality silicate = nitrate*2.5 and phosphate = nitrate/16,
//otherwise the best estimate for both was considered to be 0. When pCO2
//was estimated from TALK_LIAR and pHinsitu, a bias was first added to pHinsitu
//following Williams et al., 2017, doi: https://doi.org/10.1002/2016GB005541 , section 3.4, equation 3.
//This correction is not necessary for DIC and DIC is computed with the reported pH and the TALK_LIAR value.
//
//NOTE ON Chl_a [mg/m^3] CONCENTRATION:
//There is community-established calibration bias of 2 for the WET Labs 413 ECO-series fluorometers
//(Roesler et al, 2017, doi: 10.1002/lom3.10185).
//Chl_a has been recalculated using in situ measured dark counts. Chl_a is then divided by the Roesler factor of 2.
