More great articles coming out about deep sea mining. This one, at prestigious periodical Nature, is very well written, thoughtful, and in my opinion very correct. nature.com/articles/s4418…

Thank you to Time Magazine for agreeing to publish my Op-Ed regarding Deep Sea Mining. Space precluded going into more detail or covering even more issues relating to the topic, but hopefully this highlights some key issues. time.com/7287891/deep-s…

We should relabel "Rare Earth Metals." The mere name suggests they're hard to find - they aren't. They're "rare" because they're very tightly bound to other elements and really hard to refine or find in simple chemical form. They should be called "Tightly Bound Elements" instead.

Apologies for the frequent posts about Deep Sea Mining, but I saw this new piece of research on The Metals Company and thought it very insightful and focused on the key, economic and financial, issues. Felt compelled to forward. iceberg-research.com/2025/05/27/the…

The Resolution mine in Arizona, in the desert, was approved in May to produce 450,000 pounds of copper per year. The Metals Company's documents show they'll produce just 89,000 pounds per year. So, a single US mine will produce 5x more copper than TMC. Doubt they'll mention it.

A blast from the past, seven years ago. Final assembly of the DSV Limiting Factor at Triton Submarines in Vero Beach, Florida prior to the start of the Five Deeps Expedition. (I've heard people are interested in historical photos from back then . . .) #tritonsubmarines

So happy to hear Papua New Guinea, one of very few countries to have ever tried to mine the seafloor (with the predecessor of The Metals Company, Nautilus Minerals, which went bankrupt in 2019) is now against Deep Sea Mining at the UN Ocean Conference. postcourier.com.pg/png-opposes-de…

Continuing the effort to explore the capabilities of satellite-derived bathymetry (SDB) with partners TCarta and Greenwater by donating 1,287 sq km of UK coastal area to Seabed 2030. There might be some overlap, but hoping the UK can continue its efforts to map 100% of its EEZ.

Was able to visit the Omega museum in Bienne/Biel Switzerland. They are kind enough to feature an exhibit covering the dive by the Seamaster Planet Ocean Ultra Deep Professional (#1 of 3) on a replica of the Limiting Factor's robotic arm. Deepest diving timepieces ever. #omega

Interesting legal take on the issue of Deep Sea Mining. Talk about unchartered waters. If nodules on the seafloor are the "common heritage of mankind" as per the UN Law of the Sea, isn't mining them without the UN's permission *through the ISA* theft? ejiltalk.org/untouchable-me…

Posted just today by Tesla: They are nearing completion of their first facility in the US to manufacture renewable batteries: "LFP" batteries (Lithium Iron Phosphate), which do not use the only metals one can obtain from seafloor nodules: nickel, cobalt, manganese, or copper.

Came across this today, from April 2019. My good friends Capt. Don Walsh, first to the ocean's bottom (with Jacques Piccard) and PH Nargeolet, who trained me to dive on Titanic. We lost them both in 2023, but they will never be forgotten. It was an honor to call them shipmates.

You asked for it, so here you go. More historical footage from when the Limiting Factor was being built. My first interaction with the manipulator arm, and reviewing the electrical systems at Triton Submarines. Was just amazing. They were, and are, just the best.
