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

阿拉斯加费尔班克斯大学提供的资金用于建立季节性冰带观测网络（SIZONet）的活动。SIZONet第一阶段导致了海冰系统服务（SISS）概念的发展，描述了来自冰盖的社会效益（和潜在的负面影响）。通过评估SISS的性质和范围，ppi能够建立一个海冰观测网络，以满足科学界和关键利益相关者的需求。SIZONet建立在与几个国际伙伴的合作基础上，跨越了北极季节性冰带（SIZ）的整个纬度范围。在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的基础上，SIZONet第二阶段完善和缩小了项目范围，并侧重于维持核心观测。其目的是为科学家和利益相关者提供数据和信息：(1)解决北极环境变化研究（SEARCH）和相关工作确定的最紧迫的信息需求；(2)满足海冰用户信息需求，以海冰获取、冰作为平台、冰作为海岸灾害和海岸侵蚀调节剂为中心；(3)促进气候模拟和遥感降尺度方法的发展；(4)与SISS直接相关，使现有合作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伙伴关系。观测包括冰运动的岸基和漂冰测量，关键的质量平衡变量和关键的冰雪性质，如反照率，以及机载冰厚度和性质调查。关键利益攸关方最感兴趣的沿海冰测量包括水文系泊、调查测量和卫星图像的整合。当地的冰观测和联合冰径测绘提供了海冰地球物理学和本土海冰专业知识之间的联系。所有SIZONet数据都被纳入一个与阿拉斯加海洋观测系统、阿拉斯加地理信息网和北极合作数据和信息系统相连的存档和传播系统。

Eicken 0856867University of Alaska FairbanksFunds 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.
