Even if coastal lakes and or lagoons systems are a less studied environmental archives compared to other lacustrine systems, they provide valuable information on the reconstruction of rapid environmental changes under both terrestrial and marine forcing. Depending on their geomorphology (more or less connected to the ocean) and climate context (from tropics to high latitudes), many challenges are particular to this lacustrine system such as marine influence, high bioturbation, shallow water, evaporation or seasonal variation in salinity. In this session we encourage the presentation of studies on sediment in coastal lakes or lagoons to extract varying information at a range of different timescales (decadal to millennial) from marine submersions (tsunami, storm surge), sea-level fluctuations, anthropogenic impacts and climate variations (wet/dry periods) to ecological dynamics and water quality, with a focus on past geodynamic, climate and/or environmental forcing.
