Abstract:
During the RU-Land_2021_Yakutia summer field campaign in August and September 2021 in the Verkhoyansk Mountain Range in Eastern Yakutia and in the Central Yakutian Lowland, multispectral drone-based images were acquired over 53 selected lakes to analyse the vegetation and shallow lake waters along shores and to record the current lake shorelines. The images were taken in the course of further investigations of the lakes during that summer expedition. Baisheva et al. (2022) gives an overview of the lakes studied and the corresponding hydrochemistry. In addition, we published datasets including water isotope data of the lake (Stieg et al. 2022) and vegetation surveys of the lakeshores (Stieg et al. 2022). The dataset with the corresponding processed lake images, the so-called orthomosaics, can be found here: https://doi.pangaea.de/10.1594/PANGAEA.956223.
Here we provide the event list, which gives an overview of the relevant lake information. Due to the varying lake sizes, only sections of the shore were recorded for some lakes (see information on orthomosaic quality). Some orthomosaics contain several lakes because the lakes are small and are located close to each other. This is especially the case for the thermokarst lakes in the Central Yakutian lowland. Occasionally, there are multiple orthomosaics (indicated with _1 and _2) because either different sections of the shore have been recorded or they were acquired on different days. The lake sizes were calculated from the processed orthomosaics. For fragmented orthomosaics, additionally, Sentinel-2 satellite data was used to calculate the lake area provided in the metadata.
