Alaska Community Ice Observations - 2019-2024

This dataset contains community based observations of ice thickness throughout the winters of 2019/2020, 2020/2021, and 2021/2022. Observations are co-located within or near communities participating in the Fresh Eyes on Ice project, seeking to expand spatial coverage of ice observations and science literacy in classrooms around the state. This spatially distributed dataset provides valuable information about ice thickness through the winter for the period of 2019-2022 on lakes and rivers around Alaska, including Big Lake near Venetie, Alaska, Brown's Slough in Bethel, Alaska, Noyes Slough in Fairbanks, Alaska, the Tanana River near Fairbanks, Alaska, Shageluk Lake near Shageluk, Alaska, Third Lake near Noatak, Alaska, Alexander Lake in Galena, Alaska, Smith Lake near Fairbanks, Alaska, Big Trail Lake near Fairbanks, Alaska, Toolik Lake at Toolik Research Station, Alaska, Jan Lake near Tok, Alaska, Float Pond Lake near Nenana, Alaska, unnamed lakes in the communities of Kenny Lake, Alaska, Arctic Village, Alaska, Sleetmute, Alaska, Utqiagvik, Alaska, and McGrath, Alaska, Pippen Lake near Tonsina, Alaska, Yukon River near Eagle, Alaska, Long Lake near Eagle Village, Alaska, Sculpin Lake near Chitina, Alaska, Dog Pits Lakes near Fairbanks, Alaska, Yukon River near Rampart, Alaska, ACSA Pond near Nome, Alaska, Willow Creek near Kenny Lake, Alaska, Chena River near Fairbanks Alaska, and Cripple Creek near Fairbanks, Alaska. These observations were made by drilling of 3 holes in an undisturbed location at the site by students, teachers, and community members, as well as members of the Fresh Eyes on Ice project. Snow depth was recorded at each of the holes prior to drilling.本数据集涵盖2019/2020、2020/2021及2021/2022年冬季的基于社区的冰厚观测数据。观测点位均分布于"冰上明眸"（Fresh Eyes on Ice）项目参与社区的内部或周边区域，该项目旨在扩大全州范围内冰况观测的空间覆盖范围，并提升课堂中的科学素养。这套空间分布式数据集提供了2019至2022年冬季阿拉斯加州周边湖泊与河流的宝贵冰厚信息，覆盖点位包括：阿拉斯加州维内蒂附近的大湖、贝瑟尔的布朗斯沼泽、费尔班克斯的诺伊斯沼泽、费尔班克斯周边的塔纳纳河、沙盖卢克附近的沙盖卢克湖、诺阿塔克附近的第三湖、加莱纳的亚历山大湖、费尔班克斯周边的史密斯湖、费尔班克斯周边的大特雷尔湖、图利克研究站的图利克湖、托克附近的简湖、尼纳纳附近的浮塘湖、肯尼湖、北极村、斯利特穆特、乌特基亚维克以及麦格拉思各社区内的无名湖泊、汤森纳附近的皮彭湖、鹰附近的育空河、鹰村附近的长湖、奇蒂纳附近的杜父鱼湖、费尔班克斯周边的狗坑湖、兰帕德附近的育空河、诺姆附近的ACSA池塘、肯尼湖附近的柳树溪、费尔班克斯周边的切纳河，以及费尔班克斯周边的克里普尔溪。本次观测由学生、教师、社区成员以及"冰上明眸"（Fresh Eyes on Ice）项目成员在各点位的未受干扰区域钻取3个观测孔完成，且在钻取每个孔洞前均记录了对应点位的雪深。
