Abstract

In 1995, the first of a nearly continuous sequence of biophysical moorings was deployed at a site (M2) on the southeastern Bering Sea shelf. Over the next 15 years, 10 additional mooring sites were initiated. The resultant long-term biophysical mooring array extends over 1,800 km from the southern Bering Sea to the northern Chukchi Sea, covering most of the US Arctic. It provides a full range of oceanographic data for researchers, stakeholders, and managers. In addition, these data sets have been critical for the validation of regional ocean models. The ocean temperature data have quantified regional warming and formed the basis for understanding how warmer temperatures and loss of sea ice are modifying these high-latitude marine ecosystems. Changes observed in the context of observations from the mooring program include delayed spring bloom, low abundances of large crustacean zooplankton and crab species, seabird die-offs, changes in ocean acidification, northward expansion of subarctic fish species, and shifts in the ranges of marine mammal species.

美国北极海洋生态系统的长期生物物理观测和气候影响

1995年，在白令海东南部大陆架的一个地点(M2)部署了第一个几乎连续的生物物理系泊。在接下来的15年里，又新建了10个系泊点。由此产生的长期生物物理系泊阵列从白令海南部延伸到楚科奇海北部超过1800公里，覆盖了美国北极的大部分地区。它为研究人员、利益相关者和管理人员提供了全方位的海洋学数据。此外，这些数据集对区域海洋模式的验证至关重要。海洋温度数据量化了区域变暖，并为理解温度升高和海冰减少如何改变这些高纬度海洋生态系统奠定了基础。在系泊项目的观测背景下观察到的变化包括春季开花延迟、大型甲壳类浮游动物和螃蟹物种丰度降低、海鸟死亡、海洋酸化变化、亚北极鱼类物种向北扩张以及海洋哺乳动物物种范围的变化。

期刊介绍： First published in July 1988, Oceanography is the official magazine of The Oceanography Society. It contains peer-reviewed articles that chronicle all aspects of ocean science and its applications. In addition, Oceanography solicits and publishes news and information, meeting reports, hands-on laboratory exercises, career profiles, book reviews, and shorter, editor-reviewed articles that address public policy and education and how they are affected by science and technology. We encourage submission of short papers to the Breaking Waves section that describe novel approaches to multidisciplinary problems in ocean science.
