High-resolution bathymetric survey dataset of Yesik Lake, Kazakhstan: New insights into the morphology of the mountain water body

This dataset provides high-resolution bathymetric data for Yesik Lake, in southeast Kazakhstan's Tien Shan Mountain range. A bathymetric survey was undertaken from September 9 to 12, 2024, using a Lowrance ELITE Ti 9 multibeam sonar placed on a small vessel. The dataset comprises a digital elevation model (DEM) of the lakebed with a resolution of 1 meter, together with supplementary metadata. The supplied data facilitates comprehensive mapping of the lake's underwater topography, encompassing details on the substrate's depths, gradients, and morphological characteristics. This dataset applies to diverse research in limnology, hydrology, geomorphology, and the ecology of alpine water bodies. The data provides a crucial basis for examining sedimentation processes, evaluating water resources, and modeling the ecosystem of Yesik Lake.
