The tenth ROV dive of the expedition was conducted towards the SE corner of the Mid-Cayman Rise, transecting NNW across the rifted Oceanic Core Complex. Much of the dive was spent traversing biogenic sediment, however highlights included fresh basalt pillow lavas, and examples of frozen sheet flow lavas.
