This study focuses on the analysis of sediment core retrieved from deepest part (25 m) Pirovac Bay. A long sedimentary sequence (7.45 supplemented by a shorter (1.45 shallower bay was analyzed for sedimentological, mineralogical, geochemical, and micropaleontological (ostracod) parameters. The thickness above underlying karst paleorelief (karstic bedrock) is up to 12 m. Sediments recorded transition freshwater marine environment starting post-Neapolitan Yellow Tuff tephra sedimentation. First, floodplain developed in Bay, with intermittent pools ponds, followed wetland environment. formation shallow paleolake during Middle Holocene at 10 cal kyr BP enabled rising sea level high input karstified underground adjacent Lake Vrana (Biograd na Moru). onset intrusions through evident brackish lake Bay basin. Marine transgression flooding occurred 7.3 BP, evidenced geochemical ostracod parameters, providing crucial insights into dynamics coastal inundation under past climate change. Intriguingly, species were still present sediments, brought surficial canal Prosika groundwater discharge (numerous estavelles) along northeastern shores bay, proving their mutual influence. submerged paleolake, reported here first time, underlines sensitivity systems rise serves stress how important understanding these processes effective management zone change adaptation strategies. findings provided evidence supporting existence basins as lakes prior being flooded seawater consequence post-glacial rise.
