This dataset contains shoreline positions derived from available Landsat satellite imagery (1984 to 2023) for the Romanian Black Sea coast. The shoreline positions were derived on transects 50 m apart using the open-source toolbox, CoastSat described in Vos and others, 2019a and 2019b. Landsat coastal imagery was classified, and shoreline positions were detected at the sub-pixel scale. Transects starting and end coordinates as well as all shoreline points along the transects for each date for which a Landsat image was processed are delivered in a comma delimited CSV table. Significant uncertainty can be associated with the locations of shorelines in extremely dynamic regions, including at the locations of river mouths, tidal inlets, capes, and ends of spits. Since the Black Sea is a micro-tidal environment (less than 10 cm tidal range), the expected positional shoreline root means square error (RMSE) is less than 10% of Landsat pixel size of 30 m. These data can be used with any GIS software for shoreline evolution analysis, or other software to assist identifying and assessing possible areas of change and vulnerability, along with appropriate inclusion of uncertainty.
