Sea-ice tomography data set, Utqiaġvik, Alaska, 2013-2014

X-ray computed-tomography was performed on centrifuged sea-ice samples collected in landfast sea ice near Utqiaġvik, Alaska (AK). Data are part of the Seasonal Ice Zone Observing Network (SIZONet), by the sea-ice research group at the Geophysical Institute, University of Alaska Fairbanks, P.O. Box 757320, Fairbanks, AK 99775-7320, United State of America (USA). 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 Principle Investigators (PI) 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.

本研究针对从美国阿拉斯加州乌特恰维克（Utqiaġvik）附近固定海冰采集的离心海冰样品开展了X射线计算机断层扫描（X-ray computed-tomography）实验。相关数据隶属于阿拉斯加大学费尔班克斯分校地球物理研究所海冰研究团队构建的季节性冰区观测网络（Seasonal Ice Zone Observing Network, SIZONet）项目，该机构通讯地址为美国阿拉斯加州费尔班克斯市邮政信箱757320，邮编99775-7320。SIZONet一期项目催生了海冰系统服务（sea-ice system services, SISS）理念，该理念阐述了海冰覆盖所带来的社会收益及潜在负面影响。通过评估海冰系统服务的本质与覆盖范围，首席研究员（Principal Investigators, PI）可构建同时响应科学界与关键利益相关方需求的海冰观测网络。SIZONet依托与多个国际合作伙伴的协作，覆盖了北极季节性冰区（Arctic seasonal ice zone, SIZ）的全部纬度范围。基于该项目团队牵头组建的国际工作组所制定的统一观测协议与协同观测策略，SIZONet二期项目对项目范围进行了细化与收缩，并聚焦于核心观测的持续维持。数据引用信息：Eicken, H., R.
