Completed the 1st human descent to the bottom of the Atacama Trench with Dr. Osvaldo Ulloa of Chile. Preliminary maximum depth of 8,062 m. Extraordinary marine life observed: very many holothurians, rock faces showing chemosynthesis, and the largest bacterial tendrils I've seen.

Just two weeks ago, it appears we beat our own 2020 record of 9000m for the deepest jellyfish ever filmed. This clip is from 10,000m in the Philippine Trench, a gorgeous trachymedusae called Crossata. (Identified by Prof. Alan Jamieson, our Chief Scientist)

Just completed the deepest wreck dive in history, to find the main wreckage of the destroyer USS Johnston. We located the front 2/3 of the ship, upright and intact, at a depth of 6456 meters. Three of us across two dives surveyed the vessel and gave respects to her brave crew.

With sonar specialist Jeremie Morizet, I piloted the submersible Limiting Factor to the wreck of the Samuel B. Roberts (DE 413). Resting at 6,895 meters, it is now the deepest shipwreck ever located and surveyed. It was indeed the "destroyer escort that fought like a battleship."

This has been a difficult week for the submersible community. Deep ocean diving is very safe when industry standard certifications and procedures are followed. I will miss my good friends PH Nargeolet, who I worked with closely, and Hamish Harding, my friend in sea and space.

If the photo yesterday was great, I think this video is even better. This hadal jellyfish, again, at 7396 (!) meters, is just beautiful watch. It floats in like a spaceship, but at 0:30 begins to thrust. It comes back around 1:00 to investigate the lander. Simply amazing.

Part of the dive on the Sammy B. It appears her bow hit the seafloor with some force, causing some buckling. Her stern also separated about 5 meters on impact, but the whole wreck was together. This small ship took on the finest of the Japanese Navy, fighting them to the end.

Congratulations to Nicole Yamase, the first citizen of the Federated States of Micronesia (FSM) to dive to the bottom of Challenger Deep. The Deep is actually in the FSM's territory, so we were happy to welcome not only a local citizen but the first marine botanist on a descent.

This video shows a "pasture" of holothurians (sea cucumbers) grazing at the bottom of the Atacama Trench, near 8,060 meters. This is the most dense collection of holothurians I have ever seen in a Hadal Trench, showing the large volume of life in this deep ocean ecosystem.

Yesterday, made the first human descent to the bottom of the Izu-Bonin Trench, making Dr. Katsu Michibayashi the deepest-diving Japanese ever (initial data indicates 9,789m max depth). Saw unusually large crinoids, mantle rock from the subducting plate, and a jelly at 9,703m.

It has regularly been said: "More people have walked on the moon than have been to the bottom of the ocean."

Continued our dives in the Atacama Trench yesterday with Dr. Ruben Escribano of Chile. Dove to ~7,200 meters near the Richards Deep, witnessing growths of ultra-deep ocean coral, Elpidids Peniagone (the small animals), and unknown colors (bacterial matting?) on rock outcroppings.

It's been so wonderful to share the story of the USS Johnston with so many people. Her crew and Captain, Ernest Evans - the first Native American in the Navy to be awarded the Medal of Honor, were extraordinarily heroic. Here's video from the dive and the bridge they fought from.

Here is a clip of what it is like to skim the bottom of a deep ocean trench (the San Cristobal, South Pacific) at a depth of 8484 meters in a submersible. It feels like skimming the surface of another planet like Europa or Ganymede in a spacecraft.

Another video from the survey dive on the Sammy B. This one is from the starboard side near the bridge and forward gun mounts. We kept our distance because we spotted potentially live shells in the 40mm gun, and later towards the stern, depth charges still in their racks.

On June 18, pilot Tim Macdonald (L) and sonar specialist Jeremie Morizet (R), onboard the submersible Limiting Factor, located a torpedo rack undeniably from the USS Samuel B Roberts (DE 413): "The Destroyer Escort that fought like a battleship" during the Battle off Samar, 1944.

Caladan's Chief Scientist, Dr. Alan Jamieson, believes that in June we might have filmed the deepest jellyfish ever seen -- at the Nero Deep (9,066 meters) in the Mariana Trench. It's a trachymedusae, filmed by one of our three full ocean depth landers. Gorgeous, no?

Captain Don Walsh, USN, passed away peacefully at his home in Oregon yesterday. He bravely piloted the first craft to the bottom of the Ocean with his colleague Jacques Piccard. An extraordinary explorer, oceanographer, and human being. I'm so honored I could call him my friend.

Blue Origin built the first suborbital rocket to return from space, land vertically, and be used again. Similarly, my submersible Limiting Factor is the first vessel to repeatedly dive to the ocean's deepest point. Finally: the arrival of economical, extreme machine reusability!

Just completed the first human dive to the bottom of the Kermadec Trench, the 4th-deepest trench in the world, northeast of New Zealand. The preliminary maximum depth reached, according to submersible instruments, was 10,012 meters. Rather chaotic geology and marine life.

Dr. Dawn Wright and I completed a dive to 10,919m +/- 6m at the bottom of Challenger Deep (my 15th visit), Western Pool. We successfully tested a new 11,000 meter-capable sidescan sonar which will allows us to more precisely scan and map the seafloor in the future, at any depth.

Okay. This is the most savage, vertical wall I've yet seen anywhere. It was at about 10,500 meters along the South Wall of the Eastern Pool, Challenger Deep. This, right here, is the jagged edge of the Pacific subducting plate crashing into the Philippine Plate. >150 meters high.

Another fascinating clip from the bottom of the Izu-Bonin Trench at ~9760m. We came across a "conclave" of two ultra-deep "Eye of Sauron" jellies alongside two holothurians. I have to imagine this is what it will be like to find life on another world on, say, Europa, or Ganymede.

The team is currently investigating the underwater epicenter of the Fukishima seaquake near the Japan trench. This video from the sub shows the vertical cliff caused by the quake (ignore the date, which is incorrect). It was a massive dislocation, over 40 meters we believe.

Apologies - this isn't ocean-related, but this is the best footage I have seen of what the summit of Everest, and the South Col-based route leading to it, looks like. Very fortunate to have been there in 2010 in very bad weather (visibility about 50m)

What does it take to find the deepest shipwreck ever? An amazing Triton submersible, a great former US Navy ship, but most of all, an extraordinary team. Ship's crew, sub team, expedition support -- it takes a great deal of talent, and is much harder than it may seem.

We are back out exploring near Samar island in the Philippines, looking for the other lost vessels from the World War II Battle of Leyte Gulf, 1944. We found the main hull of the Johnston last year, and seeking her other fallen brethren in one of the Navy's bravest actions ever.

So happy to make the first human descent of the Palau Trench with former President of Palau Tommy Remengesau, Jr. Max depth reached was 8,027m. Saw some great wildlife and ascended a very steep wall. But also, heartbreakingly and all too common, a piece of human contamination.

My home of Dallas, Texas experienced a total solar eclipse today: it was amazing. To get above the local clouds, I flew two friends above the layer to 7,500 feet. Enrique A. was able to take this amazing photo of the sun's corona. Henschel O. is in the back checking for traffic.

I would argue that it is increasingly likely that the first life we find on other moons or planets will be in their oceans . . . hence the need to learn as much as we can about life in our own deep oceans, to be prepared.

Here's the video of the bottle Dr. Dawn Wright and I discovered at the bottom of the Western Pool, Challenger Deep on July 12 of this year. Tragic. Glass doesn't decompose in the ocean, so please, please don't throw bottles into the sea. It will be there for a *very* long time.
