Serious Sous Vide!

Image
In a daring culinary science experiment the current expedition team is trying a 'Mariana marinade' on the dive carrying Kelly Walsh (son of Trieste pilot Don Walsh) down into the Western Pool. Chef Manfred has a  6lb beef sirloin in a bag of marinade, plus 2 lbs each of Cajun chicken and chicken satay, being taken down to full ocean depth. (Its riding in the same compartment as all the “please shrink” styrofoam. Cups). That should drive the marinade and spice into the meat!  #infusion #sharkbait

Success!

June 7, 2020: Journey to the bottom of the Challenger Deep - and back. Longer posts describing this remarkable day will follow soon. Will add pix when we get back to 4G bandwidth.  Stay tuned!

GO for Dive Ops!

Image
We are over the eastern pool of the Challenger Deep and making final preparations for our first dive. 

Victor has just gotten into the sub to power up and run through the pre-dive checklist. I board in about 30 minutes. We aim to be off the hook and pumping down at 8am local time. Fine seas (<1 meter wave + swell), winds about 15kts and yesterday’s squally weather breaking up. A great day for diving!

At Challenger Deep.

We have arrived over the Challenger Deep. (You can see the depth - 10,352 meters or 33,963 feet - on the screen at left). Today is a day of mapping, with an autonomous lander deployment into the Western Pool.  
The weather is looking good for our dives.  All is well.  Today’s fun task is organizing a comms link from the bottom of the Challenger Deep to the International Space Station during my dive tomorrow. Fingers crossed we can make it work!

June 9: Swim time!

Image
Today’s highlight: Jumping off the ship for a swim in 36,000 ft of deep blue water.  

Otherwise a quiet day for us divers, as the Triton team works to prepare the sub for its next dive. We sent out three scientific landers back to the bottom of the trench this morning. They’re now on their way back to the surface with a day’s worth of data. Sadly, their retrieval times fall in the middle of the chef’s burger barbecue, so the Triton guys will have to eat and run, and postpone their beers until everything’s back on deck and secured. 

3 for 3!

Limiting Factor is on her way back to the surface after the third and longest dive of our expedition (4 hours on bottom). Fifty-two years elapsed between Trieste’s dive in 1960 and the Deepsea Challenger dove in 2013. We conducted three successful dives in seven days. That’s testament to LF’s innovative design and superb engineering, and those come from the outstanding engineers at Triton Submarines. Thank you Triton! And thank you Victor Vescovo for inviting me along on this remarkable journey!

Bonanza!

Our finalé, the third dive of our expedition, was hugely successful. Full duration of 4 hours on the bottom. A travers of about 1 mile in the easternmost shallow basin of the Eastern Pool. What look to be microbial mats and spectacular basal outcroppings at the eastern wall, cut by dramatic canyons. Victor and John got some great pix and videos!
