加拿大大部分地区的湖泊每年都有很长一段时间被冰覆盖。冰盖创造了与其他季节根本不同的条件,低透光率,低温,以及气体交换障碍的存在。在北温带的大部分地区,我们观察到了冰盖时期的迅速下降。气候变化预测表明,冰盖的进一步减少是可以预期的。然而,与冬季野外工作相关的后勤挑战意味着我们对冬季湖泊的现状了解相对较差。因此,对未来变化的预测充满了不确定性。
英文摘要
Lakes across much of Canada are ice-covered for long periods every year. Ice cover creates conditions fundamentally different from other seasons, with low light penetration, low temperatures, and the presence of a barrier to gas exchange. Throughout much of the North Temperate Zone we have observed rapid declines in periods of ice cover. Climate change predictions suggest further reductions in ice cover can be expected. However, logistical challenges associated with winter field work mean that we have relatively poor understanding of current conditions in lakes during winter. As a result, prediction of future changes is fraught with uncertainty.
