ABoVE: Aerial Photographs of Frozen Lakes near Fairbanks, Alaska, October 2014

This dataset includes high resolution orthophotographs of 21 lakes in the region of Fairbanks, Alaska, USA. Aerial photographs were taken on October 8, 2014, three days after lake-ice formation. These photographs were used to identify open holes in lake ice that indicate the location of hotspot seeps associated with the releases of methane from thawing permafrost. Aerial photography can be used to measure changes in lake areas and to observe patterns in the formation of lake ice and other early winter lake conditions.

本数据集收录了美国阿拉斯加费尔班克斯地区21个湖泊的高分辨率正射影像。这些航空摄影于2014年10月8日拍摄，即湖冰形成后的第三天。这些影像被用于识别湖冰中的开放孔洞，这些孔洞指示了与融化永冻土释放甲烷相关的热点泄漏位置。航空摄影可用于测量湖泊面积的变动，并观察湖冰形成及其他早期冬季湖泊状况的规律。
