After successfully avoiding the typhoon, we begin the trip back to port to complete the rest of our loading. The return leg is a good opportunity to further test the on-board instruments whilst near the relative shelter of Guam. We escalate from simpler surface tests to deep dives, then on to sampling. This ensures we … Continued

Today was a good day. Even before our 7:00 am kick-off meeting on the Bridge, Leighton, Nathan and Jimbo from the Falkor together with Ko-ichi and James from our science team had been up and busy on the back deck readying the CTD for deployment. After a quick polishing of the optical sensors (I like … Continued

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

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

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

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

This morning at 0800, Falkor arrived at the entrance to Juan de Fuca Strait on her way offshore. There was a little fog, but everyone was pleased to find relatively calm seas in the 2-meter range. The acoustic Doppler current profiler ran all night during the steam from the Straight of Georgia, through Haro Strait, … Continued

Well, not just passing, but collaborating in a very unique way.

Take a breath, now take another… for one of those breaths you have a phytoplankton to thank. About half of the world’s oxygen comes from the photosynthesis of oceanic microscopic plants, called phytoplankton. These plants grow so fast that if there wasn’t some control on their population, they would turn the oceans into a green … Continued
