This stunning octopod, Benthoctopus sp., seemed quite interested in ALVIN's port manipulator arm during last year’s expedition. Those inside the sub were surprised by the octopod's inquisitive behavior. Click image for larger view and image credit.
Expedition to the Deep Slope 2007
June 4 - July 6, 2007
This year’s “Expedition to the Deep Slope” expedition will continue our exploration and study of hydrocarbon seep communities deeper than 1000 meters in the Gulf of Mexico. Funded by the Minerals Management Service (MMS), the leader in supporting the scientific characterization of seep communities in the Gulf of Mexico, and the NOAA Ocean Exploration (OE) program, our diverse team of scientists will be using the Remotely Operated Vehicle (ROV) Jason II and the NOAA Ship Ronald Brown. Our team includes US scientists who have led the exploration, discovery, and study of the Gulf of Mexico cold seeps for the last 20 years as well as leading international seep scientists from Germany, France and Austria.
We will be revisiting several of the sites discovered last year to see how much some of the animals have grown and how the animal communities have changed. We will also be diving on at least four new sites that have never been visited before. Our team of geologists, geochemists, microbiologists, physiologists, and ecologists will be working side by side to maximize what can be learned about the deep Gulf of Mexico cold seep and coral communities during this month-long expedition of exploration and study.
