I have a cold. Yuk. I suspect I am not alone and given that there are about 50 of us all living close in one another’s company, I likely won’t be the last. But right now I feel pretty grotty. Still, so long as you wipe down your screens after reading this, hopefully you won’t … Continued
Today has been a quiet day but we’ve been making steady progress. The first CTD cast started at 4am and the last of the day will finish just before midnight. Tomorrow we will start again at 04h00. Working to that pattern we have managed to measure water column properties from top to bottom at three … Continued
The time has finally come to start our exploration of Perth Canyon and so we left dock early this morning to get a first glimpse of what lies ahead. However, as mentioned in a previous post, not everything always goes according to plan – and in our case we are still missing one part for … Continued
Well, not just passing, but collaborating in a very unique way.
As you may have noticed, there is a lot of high-tech experimental equipment and instruments on an oceanographic research cruise.
Marine Technician Jimbo (Paul Duncan) has spent all night, every night, for 24 nights keeping the Falkor’s multibeam sonar operational and recording data. The sonar sends “pings” of sound to the sea floor. The pings bounce back. The length of time between sending and receiving can be converted to depth. Each pulse sends over 400 … Continued
HAGANTA, GUAM – A diverse team of scientists are returning from a 28-day expedition onboard R/V Falkor that has more than doubled the number of known hydrothermal vent sites in the Mariana Back-arc region. This area, west of the Mariana Trench, is where plate spreading and submarine volcanism are concentrated. Several momentous findings were made, … 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
Like a bloodhound on the scent, the recent discovery of our first new vent site energized our exploration efforts. Our next target site was on Map 5, which shows two shallow “saddles” separated by deep basins. These high points correspond to places along the Mariana Back-arc where an enhanced supply of molten magma over hundreds of … Continued
Schmidt Ocean Institute’s research vessel Falkor recently arrived in Honolulu after a 21 day expedition across the equator looking at small-scale mixing in the central Pacific Ocean. She is now undergoing scheduled upgrades before heading off in early October to map the world’s largest underwater volcano, Tamu Massif. While some of the projects during the upgrade … Continued
