ctdcal.oxy_fitting

Module for processing oxygen from CTD and bottle samples.

Functions

PMEL_oxy_weighted_residual
calculate_bottle_oxygen	Wrapper function for collecting parameters and calculating oxygen values from Winkler titrations.
calculate_dV_dt	Calculate the time derivative of oxygen voltage.
calculate_weights	Calculate weights (as a function of pressure) for weighted least squares fitting.
calibrate_oxy	Non-linear least squares fit chemical sensor oxygen against bottle oxygen.
correct_flask_vol	Correct flask volume for changes from thermal expansion of glass.
gather_oxy_params	Collect Winkler oxygen measurement parameters from LabVIEW data file headers.
hysteresis_correction	Remove hysteresis effects from oxygen concentration values.
load_flasks	Load oxygen flask information from .vol file.
load_winkler_oxy	Load Winkler oxygen titration data file.
match_sigmas
oxy_ml_to_umolkg	Convert dissolved oxygen from units of mL/L to micromol/kg.
oxy_umolkg_to_ml	Convert dissolved oxygen from units of micromol/kg to mL/L.
prepare_oxy	Calculate oxygen-related variables needed for calibration: sigma, oxygen solubility (OS), and bottle oxygen
