Data from Pascuzzo et al "Development and evolution of icy layer outcrops on Mars' north polar ice cap: Observations of vertical and lateral variability"

Mars’ north polar ice cap features troughs that cut into the ice, exposing subsurface layers of different brightness and topographic expression. Specifically, these layers represent two different stratum types: lower albedo (higher dust content) marker beds, which protrude out of the wall topographically, and higher albedo (i.e., icier) interbeds which are recessed compared to the marker beds. In the paper "<i>Development and evolution of icy layer outcrops on Mars' north polar ice cap: Observations of vertical and lateral variability</i>", we investigate the role of local-scale processes by performing a detailed geomorphic characterization of variability in these strata. The dataset here contains all marker bed protrusion, surface brightness (a proxy for dust cover/content), and trough wall slope measurements used in the research.

火星北极冰盖分布有切入冰体的槽谷，暴露出亮度与地形特征各异的地下层理。具体而言，这些层理可分为两类不同的地层：一类是反照率（albedo）较低（粉尘含量更高）的标志层，其地形上突出于槽谷壁；另一类是反照率较高（即更富含冰）的互层，相较于标志层则向内凹陷。在论文《火星北极冰盖冰层露头的发育与演化：垂向与侧向变化观测》中，我们通过对这些地层的变化开展详细地貌特征表征分析，探究局地尺度过程的作用。本数据集包含本研究中使用的全部标志层突起量、地表亮度（作为粉尘覆盖度/含量的替代指标）以及槽谷壁坡度测量数据。
