James Gardner looks like a duck out of water, standing on the deck of the ship, hands in his pockets, watching the prepping of the one-person submersibles at the stern. He is not a submersible pilot. He doesn't scuba-dive, but he has provided more information in two days about the bottom terrain of this region of the Gulf of Mexico than anyone has in the past century. Gardner is a marine geologist who has created the most exquisitely detailed maps of the Flower Garden Banks National Marine Sanctuary that will ever need to be done.
