Short summary
Time series of vertical profiles of hydrophysical parameters and oxygen are critical for identifying trends in ventilation in the NE Black Sea. Such frequent measurements were performed using a moored profiler over the continental slope in winter 2016. For a brief period of time, the hypoxia onset depth rose to 97 m, the highest elevation ever recorded. As the shelf edge depth in this region is usually ~ 100 m, there is a risk of spreading of hypoxic bottom water to the outer shelf.
