Calcareous foram ooze of the ocean floor viewed from the submersible
Alvin in the Oceanographer Fracture Zone, central North Atlantic (~35N,
35W).
Trail of burrows made by an unidentified organism.

Picture below shows calcareous ooze lapping onto basaltic outcrop and
talus.
The submersible had just touched the ooze which can be seen starting to
rise in a mud cloud in the lower center of the picture.
