Empowering our communities to map rough ice and slush for safer sea-ice travel in Inuit Nunangat

海冰的粗糙度、厚度和雪泥是决定因纽特人安全和有效旅行的关键特征。不断变化的气候正在对海冰的这些特性产生负面影响，导致旅行事故和搜救事件增加。海冰不仅是狩猎平台和旅行公路，也是我们文化和身份的一部分，不断变化的海冰状况也对我们的心理健康、粮食安全和文化习俗产生负面影响。通过结合我们的因纽特人Qaujimajatuqangit（IQ），卫星数据和最先进的无人机（无人机或无人机），我们将共同制作关于海冰和雪粗糙度和雪泥的新信息，用于SmartICE冰上旅行安全地图。这些地图的制作将在北极湾、Gjoa Haven、Nain、Pond Inlet、Qikiqtarjuaq和萨卢伊特的合作社区进行试点，并最终扩展到因纽特人Nunangat的所有SmartICE社区（>24）。我们的方法将以IQ为基础，包括共同设计的因纽特人培训计划，用于基于无人机的海冰监测，以增强SmartICE开发的成熟环境数据收集。我们将调整无人机和传感器来收集高分辨率的地形和电磁数据，用于当地的旅行安全地图，以及基于光学和微波频率的海冰厚度和粗糙度的一系列新的卫星产品的地面实况。在我们的北极绒鸭协会合作伙伴的帮助下，一个不断壮大的因纽特人Nunangat社区网络将能够通过土著知识社会网络平台（SIKU）近实时地访问这些新的卫星和现场数据产品以及SmartICE冰上旅行安全地图。应社区管理委员会的要求，当地旅行安全地图也将以纸质形式在社区内分发。

Sea-ice roughness, thickness and slush are key characteristics that determine safe and efficient travel for Inuit. The changing climate is negatively affecting these sea-ice characteristics causing increasedtravel accidents and search-and-rescue incidents. Sea ice is not only a hunting platform and travel highway, it is part of our culture and identity and changing sea-ice conditions are also negativelyaffecting our mental health, food security and cultural practices. By combining our Inuit Qaujimajatuqangit (IQ), satellite data and state-of-the-art uncrewed airborne vehicles (UAVs, ordrones), we will co-produce new information on sea ice and snow roughness and slush for the operational SmartICE Ice Travel Safety Maps. The production of these maps will be piloted in ourpartner communities of Arctic Bay, Gjoa Haven, Nain, Pond Inlet, Qikiqtarjuaq, and Salluit, and eventually be expanded to all SmartICE communities (>24) in Inuit Nunangat. Our approach will begrounded in IQ, and include a co-designed Inuit training program for UAV-based sea ice monitoring to augment the mature environmental data collection developed by SmartICE. We will adapt UAVs andsensors to collect high-resolution topographic and electromagnetic data for local travel safety maps, as well as ground-truth a series of novel satellite products of sea-ice thickness and roughness, based onoptical and micro-wave frequencies. With our Arctic Eider Society partner, a growing network of Inuit Nunangat communities will be able to access in near real-time these new satellite and in-situ dataproducts and SmartICE Ice Travel Safety Maps through the Indigenous Knowledge Social Network platform (SIKU). At the request f our Community Management Committees, the local travel safety mapswill also be distributed in paper format within communities.
