Lake bed geomorphology and sedimentary processes in glacial lake Windermere, UK

Research reveals that Windermere, the largest lake in the English Lake District, exhibits a complex geomorphological landscape shaped by glacial processes and modern sedimentary dynamics. High-resolution multibeam bathymetry, backscatter data, lake bed photography, and sediment sampling identified nine sub-basins separated by steps, ridges, and isolated topographic highs, likely formed during the retreat of the British and Irish Ice Sheet post-Last Glacial Maximum. The study also uncovered five distinct lake bed facies, dominated by gyttja, with coarser sediments in shallow, lake-marginal waters influenced by dredging scars and deposits. Post-glacial slope failure and debris flows have further reshaped the lake bed, exposing finely laminated mud beneath the surface drape of gyttja. This detailed mapping provides insights into the lake's sedimentological history and ongoing processes.
