Maritime Management recently converted a 40 year old research vessel into a modern exploration vessel and has managed it through many successful operational seasons.
The ship is now equipped with purpose built ROVs operating at up to 4,000m depth and under the leadership of Dr. Ballard, a forerunner in scientific, oceanographic and archaeological research. Dr. Ballard is known for the discoveries of the Titanic, PT 109 and the Bismarck.
