It is midnight, and the ship’s lights are dimmed to limit interference with some extremely light-sensitive instruments. Fernanda Henderikx and Mathilde Dugenne lower an optical float into the water with the moon as their main illumination source. It is an unusually beautiful scene to be conducting experiments in. Many microbes have diel rhythms, just like … Continued
Jan Witting is a biological oceanographer with long-running interests in the Sub Tropical and Equatorial Pacific, where he has served as Chief Scientist on more than 20 research cruises. His work broadly addresses the linkage between climate variation, circulation, and biological production in the tropical and subtropical oceans, where he studies the effects of changing … Continued
From the heart of the cyclonic eddy, we turned the Falkor north and cruised to its edge. We found the counterclockwise spinning cyclonic eddy. Now it is time to characterize the eddy’s physical, chemical, and biological features, which means it is time to get the LRAUVs (#MicrobeEddyBots) into the ocean and put them to work. … Continued
“The first problem we had is that the vehicle wasn’t communicating with the ship’s USBL system, so we weren’t able to keep track of where the Iver was underwater,” says Nick Goumas. “That made the mission very high risk. So we decided we were confident running a simple compass calibration mission, which is when the … Continued
Anna is a Research Associate at the University of Hawai‘i, Mānoa, working in the laboratory of Dr. Edward DeLong. She joined the team to spearhead developing high throughput workflows using robotics to prepare marine microbial and marine sediment trap samples for genetic sequencing. In addition to her laboratory role, she joined the UH/MBARI LRAUV collaboration … Continued
If you have ever flown over the Pacific and looked down from the window seat, the water seems still. Viewed from this distance, the water appears stagnant with unmoving dashes of waves.
As my time on board the R/V Falkor has drawn to a close, I look back and reflect on how truly amazing and wonderful this experience was. When I first stepped on board, I was not sure what to expect. Having never been on a research vessel before, this was a completely new experience for … Continued
The swell seems invisible, but is clearly revealed by Falkor’s rocking and rolling. It represents no challenge for the experienced crew and by the end of the day, ROV SuBastian is safely back on the aft deck after twelve hours of exploring the sea bottom. While the cloudscape glows a beautiful purple and orange tint, … Continued
One of the first things we did once we arrived at West Mata volcano was resurvey the seamount with R/V Falkor’s multibeam sonar system. We knew from previous repeated bathymetric surveys that West Mata has had frequent eruptions during the last decade, as we shared in our last blog. The last survey was in March 2016, so … Continued
West Mata is a Restless Volcano. West Mata Seamount is one of only two submarine volcanoes in the world where an active eruption has been directly observed on the seafloor. An expedition in November 2008 discovered evidence that West Mata was actively erupting while exploring the water column in the area for hydrothermal plumes – but the … Continued
