This raw dataset contains in-situ hyperspectral from Legs 4 & 5 of the MOSAiC Expedition, collected by Stickle. The dataset allows to calculate remote sensing reflectance (R_rs) as well as spectral albedo. For measurements over melt ponds, co-located water depth information was collected with a measuring ruler. The Stickle hyperspectral measurement platform is a hand-held gimbal-stabilized platform for three OceanOptics STS-VIS spectro-radiometers (downwelling upwelling irradiance, upwelling radiance). Position is logged with an included GPS receiver. Data of each deployment is collected into a zip/tar file, holding a folder of plain text raw data (spectra, depth, GPS position) and image-based raw data (co-deployed action cams (AC folders)). Digital copies of field notes (if any) are also included.
