Measurements of dissolved N 2 , O 2 , Ar, C O2 , and CH 4 were made in perennially ice-covered Lake Hoare. Results confirm previous reports that O 2 concentrations in the upper water column exceed atmospheric equilibrium and that N 2 and Ar are supersaturated throughout the water column. The mean su...
