This volcanic asphalt expulsion feature was found during an exploration project where BOEM requested NOAA's Okeanos Explorer to examine a rather odd looking sonar target that we thought to be a shipwreck. It was not. This was the first time one of these so called 'Tar Lillies' was ever oberved on the seafloor in the Gulf of Mexico. Video of this feature can be seen at: https://www.youtube.com/watch?v=QAcscK81-ro This model was produced by BOEM Marine Archaeologist Scott Sorset.
