Description: 
Saturation anomaly of He in percent. 0% indicates that the He concentration is equal to that expected at equilibrium for the potential temperature and salinity of the water. ie. Hesat = (He/Heeq - 1) *100 The He saturation anomaly is calculated relative to the solubility curve of Weiss, R.F. (1971) "Solubility of Helium and Neon in Water and Seawater", Journal of Chemical and Engineering Data, 16(2), 235-241. These saturation anomaly values are from individual samples. Where a duplicate from the same Niskin was collected and analyzed, the duplicate's value is listed in the second column with the same label appended with "2".
