Texas A&M University at Galveston (TAMUG) is going deep-water exploring to investigate the mystery of three sunken ships off Galveston's coast.

The university is joined by several agencies, including the National Oceanic and Atmospheric Administration (NOAA), during Thursday and Friday's search.

A remotely-operated vehicle (ROV) from the NOAA ship Okeanos Explorer will be patrolling the Gulf of Mexico using high-definition video cameras and mounted with a lighting system to broadcast live video online.

The goal of the expedition is to figure out what or whom the ships were used by, for instance where they sailed by pirates or used for privateering.

The ship were discovered last year south of the Flower Garden Banks National Marine Sanctuary when Shell Oil Co. was surveying at a 4,300-foot depth. At the time, one of the ships was mapped and explored in detail.

Found aboard were muskets, cannons, suspected hide roles and medicinal supplies, like ginger, to treat sea sickness.

Scientists believe the ships date back to the 19th century and may have sunk together during a storm.

The other two ships will be explored next by the ROV as part of NOAA's 2014 Exploration of the Gulf of Mexico project until April 30.

Okeanos Explorer is looking at other deep-sea habitats and features.

On Wednesday, the ROV will be broadcasting video of the Keathley Canyon to explore the geology and biology. Watch the live feed here.
