We use established \r\nmethods and explore new techniques to assess changes in marine \r\ninfluence. Bathymetric and sub-bottom profiles were acquired \r\nto examine basin-wide sedimentation and a 5.8 m sediment core \r\nspanning the last 7800 cal yr BP was analyzed.  We measured \r\nmagnetic susceptibility, bulk organic matter properties, \r\nmolecular biomarkers, diatom assemblages, and elemental \r\nprofiles acquired by scanning X-ray fluorescence. These \r\ncharacteristics of the sediment reflect detailed changes \r\nin salinity and water column conditions as the lake was \r\nprogressively isolated. Three distinct litho/chemo-stratigraphic \r\nunits represent a restricted marine phase (7800–6500 cal yr BP), \r\na transitional phase characterized by intermittent marine \r\ninfluence (6500-4900 cal yr BP), and complete isolation \r\nand freshwater sedimentation (4900 cal yr BP to present). \r\nAlthough there are uncertainties in the estimate of the \r\nthreshold elevation of the lake, the timing of these phases \r\ngenerally corresponds with previous interpretations of the \r\nlocal relative sea-level history. This record captures sea-level \r\nregression following the Tapes transgression and supports the \r\ninterpretation of a subsequent sea-level stillstand, dated in\r\nHeimerdalsvatnet from 6500 to 4900 cal yr BP.","author":null,"citation":"Balascio, N.L., Z.
