Collaborative Research on the State of the Arctic Sea Ice Cover: Sustaining the Integrated Seasonal Ice Zone Observing Network (SIZONET)

PEROVICH 0856377美国陆军寒冷地区研究和工程实验室提供基金，以加强季节性冰区观测网络(SIZONet)的活动。SIZONet第一阶段导致了海冰系统服务(SISS)概念的发展，描述了冰盖产生的社会效益(和潜在的负面影响)。通过评估SISS的性质和范围，PIS能够建立一个海冰观测网络，以满足科学界和主要利益攸关方的需要。SIZONet建立在与几个国际合作伙伴的合作基础上，覆盖了北极季节性冰带(SIZ)的整个纬度范围。根据项目小组领导的国际工作组制定的共同协议和协调观测战略，SIZONet第二阶段细化和缩小了项目范围，并侧重于维持核心观测。其目的是向科学家和利益攸关方提供以下方面的数据和信息：(1)满足北极环境变化研究(SEARCH)和相关努力确定的最紧迫的信息需求；(2)满足海冰用户的信息需求，重点是获取、利用冰作为平台，以及冰作为海岸灾害和海岸侵蚀的调节器；(3)促进气候建模和遥感缩小方法的发展；和(4)直接与SISS捆绑在一起，使现有的合作能够发展成为有助于跟踪和预测北极环境变化并满足长期信息需求的合作伙伴关系。观测包括对冰运动的岸基和漂流冰测量，关键质量平衡变量和关键冰雪属性，如反照率，以及航空冰厚度和属性调查。主要利益攸关方最感兴趣的沿海冰的测量包括水文系泊、勘测测量和卫星图像的整合。当地的冰层观测和联合冰迹测绘提供了海冰地球物理和本土海冰专门知识之间的联系。SIZONet的所有数据都被纳入一个档案和传播系统，该系统与阿拉斯加海洋观测系统、阿拉斯加地理信息网以及北极合作数据和信息系统相连。

Perovich 0856377US Army Cold regions research and Engineering LaboratoryFunds are provided to build on activities of the Seasonal Ice Zone Observing Network (SIZONet). SIZONet Phase I led to the development of the sea-ice system services (SISS) concept, describing societal benefits (and potentially negative impacts) derived from the ice cover. By assessing the nature and extent of SISS, the PIs are able to build a sea-ice observing network that is responsive to the needs of both the scientific community and key stakeholders. SIZONet builds on collaboration with several international partners, and spans the entire latitudinal extent of the Arctic seasonal ice zone (SIZ). Based on common protocol and coordinated observation strategies developed in the context of an international working group led by the project team, SIZONet Phase II refines and narrows the scope of the project and focuses on sustaining core observations. The aim is to provide data and information to scientists and stakeholders that: (1) address the most urgent information needs identified by the Study of Environmental Arctic Change (SEARCH) and related efforts; (2) meet sea-ice user information needs, centering on access, use of ice as a platform, and ice as coastal hazard and regulator of coastal erosion; (3) contribute to development of down-scaling approaches for climate modeling and remote sensing; and (4) are directly tied to SISS, allowing existing collaborations to grow into partnerships that can help track and predict Arctic environmental change and meet long-term information needs.Observations include shore-based and drift-ice measurements of ice motion, key mass-balance variables and critical snow and ice properties such as albedo, as well as airborne ice thickness and property surveys. Measurements in coastal ice, of greatest interest to key stakeholders, include hydrographic moorings, survey measurements and integration of satellite imagery. Local ice observations and joint ice-trail mapping provide a link between sea-ice geophysics and indigenous sea-ice expertise. All SIZONet data is ingested into an archival and dissemination system linked to the Alaska Ocean Observing System, the Geographic Information Network of Alaska, and the Cooperative Arctic Data and Information System.
