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（Mars' north polar ice cap）发育有切入冰体的槽谷，裸露的冰下地层呈现出各异的亮度特征与地形表现。具体而言，这些地层可划分为两类不同的岩层：一类为低反照率（albedo，尘埃含量更高）的标志层（marker bed），在地形上突出于槽谷壁；另一类为高反照率（即更富含冰）的夹层（interbed），相较于标志层则呈凹陷状态。在题为《火星北极冰盖冰层露头的发育与演化：垂直与横向变化观测》（Development and evolution of icy layer outcrops on Mars' north polar ice cap: Observations of vertical and lateral variability）的论文中，本研究通过对这些地层的变化开展详细的地貌特征表征分析，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出量、地表亮度（作为尘埃覆盖度或含量的替代指标）以及槽谷壁坡度的测量数据。
