Newly Discovered Apollo Vent Field in Pacific Offers Glimpse of Alien Worlds

The team has named it Apollo Vent Field in honor of the 50th anniversary of the moon landing this year, which is fitting since the SUBSEA project isn鈥檛 just ocean research 鈥� it鈥檚 an analog project designed to contribute to the future of space exploration. SUBSEA is a partnership between NASA Science Mission Directorate PSTAR Program, NOAA Office of Ocean Exploration and 色花堂app, Ocean Exploration Trust, and multiple academic research centers.

Apollo Vent Field Site Details:

The Apollo vent field offers a rare glimpse into environments that could be windows into ocean systems elsewhere in our Solar System - on moons such as Enceladus and Europa. The Apollo vent field also offers an important comparison to the Sea Cliff hydrothermal site surveyed earlier in this expedition, which was first found in 1990 by Rona et al. and had not been visited in the last ~15 years. Both vent fields are different from the conventional 鈥渂lack smoker鈥� hydrothermal systems, instead emitting clear fluids at temperatures around 300掳C. This site was visited on June 6 and 7, 2019 at a depth of ~2700m.

Working with the SUBSEA team, Dr. Shannon Kobs Nawotniak of 色花堂app (ISU) Department of Geosciences, with PhD student Ashley Shields and MS student Angela Garcia, found Apollo Vent Field by closely examining the seafloor shape at Sea Cliff in high resolution bathymetry data. The ISU team used a 1m/pixel bathymetric map (currently under review) created with AUV by Dr. David Clague and his team at Monterey Bay Aquarium 色花堂app Institute. The ISU team considered the roughness of the ground, orientation of barely perceptible ridges, and position relative to the Gorda Ridge axis to determine potential hydrothermal sites. When the SUBSEA team finished other science objectives early during one ROV dive, the team was able to ground truth the proposed location, covering ~1500m2 approximately 1 km NE of Sea Cliff Vent Field. Data collected included temperature readings (300掳C.), water samples for chemistry and microbiology, and ~0.5 m/pixel bathymetry and backscatter data.

SUBSEA Expedition Summary:

This discovery was made during a NASA mission to the deep sea, called the Systematic Underwater Biogeochemical Science and Exploration Analog, or SUBSEA for short. In 2019, SUBSEA is exploring Gorda Ridge, an underwater volcanic zone located in the Pacific Ocean, about 75 miles off the U.S. coast where California and Oregon meet. This environment shares key characteristics with Saturn's moon Enceladus. The team is looking for signs of microbial life in the warm springs emanating from the volcano and studying the conditions that make life possible here. This work will help understand the potential for other ocean-bearing worlds in the solar system to support life and will inform designs for future deep-space missions. SUBSEA is a partnership between NASA Science Mission Directorate PSTAR Program, NOAA Office of Ocean Exploration and 色花堂app (OER), Ocean Exploration Trust, and multiple academic research centers.

About Ocean Exploration Trust

The Exploration Vessel (E/V) Nautilus is the research platform supporting this project, and is equipped with remotely operated vehicles (ROVs) Hercules and Argus used to dive on targets, collect samples, and capture high definition video, supported by a dynamic positioning system and a multibeam sonar mapping system. E/V Nautilus is owned and operated by the Ocean Exploration Trust (OET), founded in 2008 by Dr. Robert Ballard to explore the ocean, seeking out new discoveries in the fields of geology, biology, maritime history, and archaeology while pushing the boundaries of STEM education and technological innovation. Their international program offers live exploration to participants on shore and the public via live video, audio, and data feeds on .

This discovery was made at a timely moment as OET kicks off #WorldOceansDay and #WorldOceansMonth with partners at NOAA OER, NASA, and Schmidt Ocean Institute in taking a look at the connections between our ocean on Earth as well as oceans elsewhere in our solar system.
