摘要 盐水层间距是在 1978 年 1 月 19 日取自加拿大巴芬岛 Eclipse Sound 的岩心样本中测量的。对雪和冰条件的观察以及整个生长季节的气温记录使盐水层间距与海冰的生长速度相关联。生长速度与气候有关，冰中垂直盐水层间距剖面提供了以前天气状况的记录。这表明间距与生长速率成反比，并且还可能取决于晶体取向。随着岩心样品底部附近的深度的增加，间距迅速减小，这与间距和生长速率之间的一般关系不相容。在做出明确的声明之前，必须对来自不同地点、在各种气象条件下生长的岩心进行研究。
Abstract Brine layer spacing has been measured in a core sample taken 19 January 1978 from Eclipse Sound, Baffin Island, Canada. Observations on snow and ice conditions and a record of air temperatures for the entire growth season allowed correlation of the brine layer spacing with the growth rate of the sea ice. Growth rate is related to climatology, and the vertical brine layer spacing profile in the ice provides a record of previous weather conditions. It is suggested that the spacing is inversely proportional to the growth rate, and could also be dependent on crystallographic orientation. The spacing decreased rapidly with depth near the bottom of the core sample, and this is not compatible with a general relation between spacing and growth rate. Before a definitive statement can be made, cores from a variety of locations, grown in a range of meteorological conditions, will have to be studied.
