TURTLE - Beach profiles and bathymetry (16 Oct 2023 – 29 Jan 2024)

Bathymetric and topographic survey data collected during the TURTLE experiments on Galveston Island, TX, USA in the fall of 2023. The data includes handheld RTK-GPS cross-shore profiles, collected between October and December 2023, and bathymetric echo-sounder survey data, collected on 29 January 2024. This dataset is part of the collection <em>TURTLE: Measurements of groundwater, hydrodynamics, sand temperature, and sediment characteristics at two beach transects on Galveston Island, Texas, USA.</em><br>A full, detailed description of the experiments, instrumentation, and collected data is published in:Christiaanse, J.
