It is 2:30am. The day started early with the morning meeting and has not slowed down since. We are at station number 6, the first 24 hour-long station. Dr. Mak Saito is operating the winch at R/V Falkor’s aft deck as the Trace Metal Rosette (TMR) comes up. He has not left this post for … Continued
With the discovery of big plumes and active venting on the seafloor during CTD tow-yo 6 we really hit the jackpot out here on the Mariana back-arc. This led to further investigation of the site with the Autonomous Underwater Vehicle (AUV) Sentry. The result was a beautiful high-resolution bathymetry map [FK151121_sentry_bathy.jpg] and an even more-detailed photographic … Continued
I wake up disoriented, not remembering where I am. I sit up and bang my head against the bunk above me. Oh, right, I’m on the Research Vessel Falkor in the Mariana Back-Arc (western Pacific). I stumble-walk across my cabin as the whole room is swaying side to side with the motion of the sea, … Continued
Appendix Two: Hydrothermal Exploration of the Mid-Cayman Rise CTD Casts FK008
We’re aboard the R/V Falkor on a #HydrothermalHunt in the unexplored parts of the Mariana back-arc. Hydrothermal vents host some of the most unique chemical environments and biological ecosystems on the planet. On this expedition, we are focussing our search on the segments of the Mariana back-arc that are numbered 4-10 on this map. We … Continued
2026 - The Southwest Atlantic Ocean In 2026, we’ll continue to explore the Southern Atlantic, one of the least explored marine regions on Earth. From the deep waters off Brazil to seamounts in the Mid-Atlantic, international teams will document biodiversity, study physical, chemical, and geological phenomena, and map seafloor features. We’ll support a host of … Continued
A new technology detects trace amounts of oxygen in an environment where previously these life-supporting molecules were below the limit of detection. Photos are available here ANTOFAGASTA, Chile – Using a new technology called a mini trace analyzer insitu logger, or mTail, an international team of scientists on a Schmidt Ocean Institute expedition has found … Continued
Scattered along the barren ocean floor lie uncounted hydrothermal vent sites—oases of hot, chemical-rich, life-nurturing fluids. These oases are a submarine version of Yellowstone National Park. Cold seawater in deep cracks is heated by cooling magma, becomes buoyant, and rises to the seafloor. Instead of forming a warm pond, as at Yellowstone, the hot fluid … Continued
Lots to tell you about today. We started off with a CTD coming on deck from the furthest north point we have been to (and also about as unpromising as can be) since we started our latest search. Then, because Casey and the Nereus team needed to do some engineering work on the back deck … Continued
Suddenly, the whole ship seems to have its groove on and science is really clicking. By deciding to focus on our shallowest site, we are stepping up the pace to dive every day, starting at 04h00, and staying out as long as we’re allowed. Reminds me of Summer nights when I was about 10 and … Continued
