Summary: | This paper describes the growth of sea ice and the salinity profiles observed in Eclipse Sound near Pond Inlet, Baffin Island, Canada, during the winter of 1977-78. A numerical method of calculation has been developed to incorporate the variations in snow conditions and physical properties of ice and snow during the growth season. It is shown that the growth rate can be predicted reasonably well. It is also shown that the vertical salinity profile in the ice towards the end of the season, provides a record of previous climatological condtions. A dependence has been shown between the predicted growth rate and the measured salinity. Cet article décrit la croissance de la glace de mer et les profils de salinité observés à Eclipse Sound près de Pond Inlet, dans l'ile de Baffin, Canada, pendant l'hiver 1977- 78. On a mis au point une méthode numérique de calcul pour incorporer les variations dans les conditions de la neige et dans les propriétés physiques de la glace et de la neige pendant la saison d'accumulation. On montre que la vitesse de croissance peut être assez bien prévue. On montre, de plus, que les profils verticaux de salinité dans la glace, jusqu'à la fin de la saison, constituent un enregistrement des conditions climatologiques passées. On a montré qu'il y avait une liaison entre la vitesse de croissance prévue et la salinité mesurée. Peer reviewed: Yes NRC publication: Yes |
