EOUATIONS FOR DETERMINING THE GAS AND IS. SECURITY CLASS. (of this report) Unclassified 1S. DECLASSI FICATION/ DOWNGRADING SCHEDULE DISTRIBUTION STATEMENT (of this Report)Approved for public release; distribution unlimited. ' Equations are developed that can be used to determine the amount of gas prernt in sea ice from measurements of the bulk ice density, salinity and temperature in the temperature range of -2 to -30C. Conversely these relationships can be used to give the density of sea ice as a function of its temperature and salinity, considering both the presence of gas and of solid salts in the ice. Equations are also given that allow the calculation of the gas and brine volumes in the ice at temperatures other than that at which the bulk density was determined.-J AN5 5
