The impacts of climate change on Arctic marine systems are noticeable within the scientific “lifetime” of most researchers and the iconic image of a polar bear struggling to stay on top of a melting ice floe captures many of the dominant themes of Arctic marine ecosystem change. But has our focus on open‐ocean systems and parameters that are more easily modeled and sensed remotely neglected an element that is responding more dramatically and with broader implications for Arctic ecosystems? We argue that a complementary set of changes to the open ocean is occurring along Arctic coasts, amplified by the interaction with changes on land and in the sea. We observe an increased number of ecosystem drivers with larger implications for the ecological and human communities they touch than are quantifiable in the open Arctic Ocean. Substantial knowledge gaps exist that must be filled to support adaptation and sustainability of socioecological systems along Arctic coasts.

多种气候驱动因素加快了北冰洋沿岸生态系统变化的速度和后果


气候变化对北极海洋系统的影响在大多数研究人员的科学“一生”中是显而易见的，北极熊努力留在融化的浮冰顶部的标志性图像捕捉到了北极海洋生态系统变化的许多主要主题。但是，我们对更容易建模和远程感知的开放海洋系统和参数的关注是否忽略了一个反应更剧烈、对北极生态系统具有更广泛影响的因素？我们认为，北极沿岸正在发生一系列与公海相辅相成的变化，并通过与陆地和海洋变化的相互作用而放大。我们观察到越来越多的生态系统驱动因素，对它们所接触的生态和人类社区的影响比开放的北冰洋中可量化的影响更大。存在巨大的知识空白，必须填补这些空白，以支持北极沿岸社会生态系统的适应和可持续性。
