Gas bubbles from a natural seep rise up in front of a calibrated grid added to the front of the Little Hercules remotely operated vehicle, enabling the collection of imagery data that will allow scientists to assess sizes and rates of bubble escape from a seep.

The fifth remotely operated vehicle (ROV) dive of the cruise was conducted today at the Pascagoula Salt Dome. A calibrated grid was added to the front of the ROV, enabling us to collect imagery data of seeps with our high-definition video cameras that will allow scientists to assess sizes and rates of bubble escape from a natural seafloor gas seep. Measurements were conducted at several natural seep sites where bubbles of gas rise up from the seafloor.
