None of the indicators are currently operational for the assessment of Descriptor 1 for any marine turtle species, due to the lack of threshold values and too patchy data, although some data are available that provide information on incidental catch mortality (D1C1), abundance (D1C2), and distribution (D1C4) of marine turtles. The methodological standards associated with the D1 criteria will be specified following further studies, as provided for in Ministerial Order 2019 on the definition of good environmental status of marine waters. The summary of the assessment is available via this link: https://doi.org/10.13155/60198
