Yukon River Basin Fire and Permafrost Study: Elevation of soil surface and permafrost table along transects with different fire disturbance regimes (2009-2012)
收藏资源简介:
Two 100 - 200 m transects were established on hilly loess deposits in the Yukon Flats near Boot Lake to monitor annual changes in the permafrost table and thaw settlement under different fire disturbance regimes. One was located in an area that burned around 1925; the other transect was located in a 2009 burn. Both transects were partially affected by a fire in 1967. This dataset includes the elevations of the ground surface, permafrost surface, water table, and surface organic thickness measurements. Note that there was compaction of the organic layer due to human disturbance along the portion of the transect that burned in only 1925. These transects are associated with the burned and unburned silty upland sites detailed in related datasets.
在布特湖(Boot Lake)附近的育空平原(Yukon Flats)丘陵黄土沉积区域,共布设两条长度为100~200米的样带(transect),用于监测不同火灾干扰制度下的永冻层顶面(permafrost table)年际变化与融沉现象。其中一条样带位于约1925年过火的区域,另一条样带位于2009年过火的区域;两条样带均在1967年的火灾中受到部分影响。本数据集包含地表高程、永冻层顶面(permafrost surface)、地下水位高程以及地表有机层厚度的实测数据。需注意:仅在1925年过火的样带区段,有机层因人为干扰发生了压实作用。本样带与相关数据集所载的过火与未过火粉质高地站点相关联。
