Very-high-resolution image acquisition over arctic sea ice using multiple remote sensing platforms

Abstract

Remote sensing of arctic sea ice provides useful information on the status of sea ice such as concentration, extent, motion and surface composition. Very-high-resolution (VHR) imaging acquiring images with a spatial resolution from few meters to few centimeters has become available from various remote sensing platforms, e.g., satellite, helicopter and unmanned aerial vehicle. In this study VHR image acquisition over arctic sea ice using multiple remote sensing platforms, and image processing protocols for extracting information from the acquired images are demonstrated. The VHR images and products from the images can be applicable to validate sea ice concentration data from coarse resolution remote sensing data, and can be used as an alternative reference data decreasing requirements for in-situ measurements. Furthermore, the VHR images can support safe research activities using icebreaker research vessel by providing the sea ice condition around the vessel.
