Supplied Name:

Conversion Necessary: 

Gas Saturation Anomaly expressed in percent. Defined as:

delta_He = (C(He)/C*(He)-1)*100%

where C(He) is the concentration of helium in seawater (as reported) in units of nmol/kg, and C*(He) is the solubility concentration in the same for helium at the potential temperature and salinity

of the water computed from the solubility relations measured in the laboratory by Weiss (1971).
