We know that Loihi Seamount is affected by hydrothermal activity that can lead to giant plumes of rusty flecks in the water column and at the seafloor. Those marine particles form when hydrothermal iron is oxidized either by microorganisms (the “iron eaters” that poop rust) or by small amounts of oxygen dissolved in the deep … Continued
Join me, Dana Yoerger on my first journey aboard R/VFalkor to Loihi Seamount. With over 70 oceanographic expeditions under my belt, I still get excited for the unknown adventure that awaits mapping underwater seamounts and volcanoes, who knows what discovery is just around the corner. July 1st, 2014 We had a good dive with Sentry … Continued
Last evening Falkor made the turn around South Point, Hawaii Island, and a couple hours later we arrived at Loihi Seamount. This is my fifth expedition to Loihi, and a trip that I have been looking forward to for many years. This cruise is especially exciting because we are focusing on the unexplored reaches of … Continued
After spending a day off shore and calibrating all the equipment, we are off to our destination! It will take approximately 15 hours to transit to the south east corner of Hawaii Island to Loihi Seamount. Since the remainder of the cruise will focus on what we find at the world’s largest underwater volcano, let’s … Continued
Our capabilities for exploring the seafloor have undergone a revolution in the last few decades. Depending on the scientific problem we need to solve, we can image from the ship and see large-scale features like mountains, or get very close to the seafloor in a submersible or remotely operated vehicle, and see tiny animals up … Continued
When you think about the amount of preparation needed for a cruise, the whole thing can make you exhausted. Months of planning, timelines, securing equipment and tools needed for the excursion, and science preparation, all play an important part of getting ready. . Checking and double checking is a critical piece of this preparation, as … Continued
If you have not already become enamored by the beautiful and diverse marine zooplankton that we have been talking about over the past week, let me give you one more reason– they glow! Well, some of them do at least, and one of the projects on this cruise has been to dig a bit deeper … Continued
Our time on the R/V Falkor is nearly finished, the last samples have been collected, our equipment has been washed and dried in the afternoon sun, and the pace of work on the ship has slowed. The scientists have transitioned from the busy, physical work of deploying and recovering the CTD-Rosette, MOCNESS and ring net to … Continued
I sit awkwardly, muscles tensed, waiting for my target to float into view. My weapon, a glass pipette, poised to strike. Suddenly something gently glides into view, looking deceptively relaxed, with its’ six legs splayed wide, gently feeling the water currents. I slide the pipette carefully into the water, quietly sneaking upon the baby zooplankton … Continued
