This raw dataset contains in-situ hyperspectral and co-located water depth measurments from melt ponds on Legs 4 & 5 of the MOSAiC Expedition, collected by Böötle. The dataset allows to calculate remote sensing reflectance (R_rs) over melt ponds with associated melt pond water depth measurements.The small Böötle remote controlled water colour spectro-radiometry platform allows for the simultaneous collection of hyperspectral, bathymetric and temperature data in waters as shallow as 15cm. It is equipped with three OceanOptics STS-VIS spectro-radiometers (downwelling above-water and below-water irradiance, upwelling below-water radiance), a Tritech PA500 point sonar (water depth), and a DS18B20 temperature probe (subsurface water temperature). Propulsion is achieved by two air screws, thereby limiting the impact on the water column and the bottom substrate. The platform is remotely controlled by the operator with a maximum range of 100m. A web interface is provided via a wireless network, which allows for ... : The Development of a hyperspectral measurement platform was supported by Prof. Dr. Werner Petersen-Stiftung (funding number 610). ...
