註釋Observations made during the 1990s and 2000s indicate that the Arctic physical environment and associated ecosystem are undergoing remarkable changes. The observed reduction in Arctic sea ice extent is arguably the strongest, most powerful visual symbol of climate change. The Arctic Ocean is changing as well. Here we discuss, from an observational point of view, the present understanding of the circulation, water masses, and stratification of the Arctic Ocean, highlighting the changes that have taken place during the past few decades. Many of these ocean signals evolve rapidly, making it essential that the state of the Arctic/Subarctic is observed continually, using all the recent advances that have been made in high-latitude monitoring and in Earth System understanding. Taking recent investigations of the Arctic atmosphere and sea ice as guides, we deem it likely that signatures of anthropogenic climate change in the Arctic/Subarctic Seas will begin to emerge above the high level of natural variability within the next decade.
