Science Log

We arrived late last night back in Jacksonville, Florida docking at the Atlantic Marine Docks – taking on 8 scientists who will leading the ROV operations – over the next few days. The next morning was a flurry of activity as the science crew began to unload their equipment and the crew of the Pisces operated the cranes and prepared the the sides of the ship and the winches for deployment of the ROV.

While Jeannine stayed aboard to help running cables and rigging the GPS equipment needed for pinpointing the position of the ROV relative to the ship – I chose to join the scouting party inland; myself, Lieutenant Dunsford, Engineer Tony Assouad and Lead Scientist Andy David made contact with local at the village of “Walmart” and acquired much needed supplies.

AtlantisGear was stowed and the equipment set up, the science party met for their safety briefing, followed by a larger conversation of what we will be accomplishing over the next couple of days. We plan to take the “Deep Ocean ROV” to at 3 sites – testing in and outside the MPA or “Marine Protected Area” about sites a day. We will be running mostly day time operations and transitioning to next station at night as well as doing some multibeam mapping – using the same type of technology I mentioned in yesterday’s blog. When the Pisces arrives in an area it will begin to “mow the lawn” – doing transects back and forth to create a map of the ocean floor below so the scientists can better choose targets or areas to avoid during the daytime ROV operation. For the most part we are assisting the scientists with the launching and retrieval of the ROV as well as monitoring what the ROV sees from a TV in the Dry Lab on the Pisces.

Like a lot of science the ROV will be recording a ton of data which will be more carefully evaluated over the next few months after the voyage. Many of the places we document in and out of the MPA will be explored again to see changes – so in a way this study sets a baseline for future missions. I am excited to see how they launch the ROV, which will give me some ideas for when my Innovation Technology Seminar launches their little rovers in a few weeks. The operator/pilot of the rover will be inside the dry lab talking through a headset to another rover scientist outside monitoring the 900 feet of cable – talking to a deck crew member operating a winch. We are hoping not only for calm waters on the surface for deployment-but quiet currents below so ROV has the opportunity to explore, rather than ride the current.

A few porpoises rolled along side the ship enough to enjoy, but too quick to get a good picture. Only the gray pelicans on the dock would stand still to pose. Before we pulled out of Jacksonville we climbed to the top of the Flying Deck to watch the Space Shuttle Atlantis launch in the distance. Even though we didn’t do much today it was still a pretty great day. đŸ™‚
