Equations for Determining the Gas and Brine Volumes in Sea-Ice Samples

  • G. F. N. Cox (a1) and W. F. Weeks (a1)

Abstract

Equations are developed that can be used to determine the amount of gas present in sea ice from measurements of the bulk ice density, salinity, and temperature in the temperature range of −2 to −30 °C. 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.

Résumé

On a établi des équations utilisables pour déterminer le taux de gaz inclus dans la glace de mer à partir de mesures de densité, de salinité et de température dans les gammes de températures entre −2 °C et −30 °C. Inversement ces relations peuvent être utilisées pour calculer la densité de la glace de mer en fonction de la température et de la salinité, en prenant en compte à la fois la présence de gaz et de cristaux de sel dans la glace. On donne aussi des équations qui permettent le calcul du volume de gaz et d’eau salée dans la glace à des températures autres que celle pour laquelle la densité a été déterminée.

Zusammenfassung

Es werden Gleichungen aufgestellt, die zur Bestimmung der Gasmenge in Meereis aus Messungen der mittleren Eisdichte, des Salzgehaltes und der Temperatur im Bereich von −2 bis −30 °C herangezogen werden können. Umgekehrt lassen sich diese Beziehungen zur Bestimmung der Dichte von Meereis in Abhängigkeit von seiner Temperatur und seines Salzgehaltes unter Annahme des Vorhandenseins von Gas und festen Salzen im Eis benutzen. Weitere Gleichungen erlauben die Berechnung des Gas- und Sole-Volumens im Eis bei Temperaturen, die von jenen absweichen, bei denen die mittlere Dichte bestimmt wurde.
