Investigating limnological processes and modern sedimentation at Lake Żabińskie, northeast Poland: a decade-long multi-parameter dataset, 2012–2021

Abstract. Here, we present the dataset from a decade-long monitoring at Lake Żabińskie, a hardwater and eutrophic lake in northeast Poland. The lake contains annually laminated (varved) sediments which form a unique archive of environmental variability in the past. Regular measurements of the lake water physical and chemical characteristics were done using multiparameter sonde and a set of temperature sensors deployed in the water column. Seasonal variability of sediment fluxes was documented by a sediment trap. Field sampling provided information about the hydrochemistry of incoming streams and of the outflow from the lake. The overall monitoring program was designed to capture a pattern of relationships between meteorological conditions, limnological processes, and modern sedimentation, and to answer the question if meteorological and limnological phenomena can be precisely tracked with varves. However, this dataset can also be a solid background for modeling physical and biogeochemical processes in lakes. The dataset is archived at https://doi.org/10.34808/bsk4-eg58 (Tylmann et al., 2023).
