Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
