Abstract:
Airborne light detection and ranging (LiDAR) is a remote sensing technology that quantifies the travel time of photons emitted in pulses from a LiDAR instrument to travel to and reflect back from objects. Knowing the travel time for the photons and accounting for the speed of light, distances to objects from the instrument can be quantified. When LiDAR is acquired over forested areas some of the pulses will find canopy openings and "penetrate" to the ground with others striking the canopy at various heights above the ground, generating an XYZ point-cloud of eastings, northings, and elevations.

Where once the Arctic basin held predominantly old, thick perennial sea ice, it is now increasingly occupied by young, thin seasonal ice. The sea ice surface topography, which affects and is affected by many of the physical processes operating at the interface between ocean, sea ice and atmosphere, is closely related to the age and type of sea ice cover. In this thesis, new methods are presented for measuring and understanding sea ice topography using Light Detection and Ranging (LiDAR) technology.
