Expedition
Internal Wave Motion of the Southern Black Sea
Expedition NA012 in the Black Sea explored the transitional zone between the oxic and anoxic water layers along the paleoshoreline at ∼155 m depth. This expedition conducted comprehensive side-scan sonar survey grids at depths from 100- 400 m off Eregli and Sinop, Turkey to document acoustic changes in sediments across the oxic/anoxic boundary.
