- The primary objective of the dive on April 24, 2014, in the Gulf of Mexico was to investigate an approximately 60 meter-long sidescan acoustic target, which was suspected to be a shipwreck.
The site was approached from the southwest, across a flat, sedimented seafloor characterized by scattered black areas suggestive of bacterial mats and a number of unbranched bamboo corals and holothurians. Within minutes of observing the first part of the suspected shipwreck, it became clear that the feature was not man-humade, but a natural phenomenon that was nicknamed a “tar lily.”
Discussion between the shore and the ship zeroed-in on the likeliest explanation - that this feature was a flower-like extrusion of asphalt at the seafloor - the first of its kind documented in this area of the Gulf of Mexico.
After documenting the first asphalt extrusion, D2 investigated a second sonar anomaly which turned out to be another "tar lily."
