Overview and Benchmark on Multi-Modal Lidar Point Cloud Registration for Forest Applications

We describe the morphological characteristics of anastomosing (labyrinthine) bedrock channels to enhance the current understanding of subglacial meltwater dynamics of the Innuitian Ice Sheet. Our work reveals a morphological similarity between labyrinthine channels and other landscapes modified by glacial floods. We argue that the presence of anastomosis, distinct erosional surfaces, and longitudinal profile slope breaks imply formation by short-lived episodes of erosion associated with floods.

We present field measurements collected during the Finnish Antarctic Research Program (FINNARP) 2022 expedition at Aboa station in Dronning Maud Land, Antarctica. Weekly observations were taken at the automatic weather station site and at selected overpass locations of two satellites. The dataset includes continuous meteorological records, snow pit profiles, ground- and drone-based radiation measurements, and snow surface roughness from laser scans.
