The Arctic is changing rapidly in response to a warming global climate, with a reduction in sea-ice coverage providing the most obvious indicator. However, the impact of this reduction in sea- ice on water column and seafloor ecology is much less certain. Changing physical conditions potentially impacts on the timing, magnitude and distribution of both ice algae and pelagic primary production(1,2) with as yet unresolved effects on trophic pathways which support both pelagic and benthic consumers(3). The recently funded NERC Arctic PRIZE project (Arctic PRoductivity in the seasonal Ice ZonE) aims to determine how these sea ice changes will affect biological and biogeochemical systems in this climatically-sensitive region.

随着全球气候变暖，北极正在迅速变化，海冰覆盖面积的减少提供了最明显的指标。然而，海冰减少对水柱和海底生态的影响则不那么确定。物理条件的变化可能会影响冰藻和浮游初级生产的时间、规模和分布（1、2），对支持浮游和底栖消费者的营养途径的影响尚未得到解决（3）。最近资助的NERC北极奖项目（季节性冰区的北极生产力）旨在确定这些海冰变化将如何影响这一气候敏感地区的生物和地球化学系统。
