Gouge marks on deep-sea mud volcanoes in the eastern Mediterranean: caused by Cuvier's beaked whales?
Enigmatic seafloor gouge marks at depths of 1700-2100m have been observed from submersible during geological survey work studying mud volcanoes in the eastern Mediterranean Sea. The marks consist of a central groove (about 10 cm deep and 1-2m long), superimposed on a broader bowl-shaped depression (...
