How #DeepSea Cables That Power World Are Made
#Undersea routes are often preferred option for sharing #electricity between countries or simply keeping cables out of sight
“We are basically sold out through 2028,” Massimo Battaini, CEO of #Prysmian, said in an interview at the plant. He added that orders on the books for these conduits, which can carry up to two gigawatts of power, have jumped to around €17 billion from €2 billion five years ago

Sea spiders found farming methane-eating #microbes in cultivated biofilm phys.org/news/2025-06-sea-spid

Diverse, epibiotic #methanotrophs serve as a source of nutrition for #DeepSea methane seep Sericosura. By Bianca Dal Bó et al. pnas.org/doi/10.1073/pnas.2501

"#MethaneSeeps are areas of the seafloor where #methane forms flourishing ecosystems... 3 species of #SeaSpiders were discovered to host dense layers of CH4-consuming microbes on their exoskeletons... and graze upon them with specialized mouthparts"

Want to Be a #DeepSea Explorer? Don’t Worry, There’s Lots Left.
Humans have visually documented about 1,470 square miles, or a mere 0.001 percent, of the deep #seafloor, according to a new study. That’s a little larger than the size of Rhode Island.
Researchers collected more than 43,000 records of dives and assessed the photos and videos to determine how much of the bottom has been seen by humans.

New bacterial genome announcement from our team:

Draft genome sequence of Desulfobacterota strain M19, a mesophilic sulfur-disproportionating bacterium from a deep-sea hydrothermal vent on the Mid-Atlantic Ridge journals.asm.org/doi/10.1128/m

This new bacterium was found on a #DeepSea hydrothermal vent, 1663m deep under the Atlantic ocean surface. It can grow by both "eating" and "breathing" a single chemical—pure elemental sulfur.

Experts alarmed over Trump’s promotion of #deepsea #mining in international waters
Critics call for an industry moratorium until more scientific data can be obtained.
On April 24, President Trump signed an #executiveorder promoting #deepseamining in the US and international waters, touting the industry’s potential to boost the country’s economic growth and national security.
Thirty-three countries are also calling for a moratorium or outright ban on deep-sea mining.

Rare giant "shrimp" is more widespread than previously believed, new findings reveal phys.org/news/2025-05-rare-gia

The supergiant #amphipod Alicella gigantea may inhabit over half of the world’s oceans royalsocietypublishing.org/doi

"#Amphipods like A. gigantea are #shrimp-like #crustaceans known for their narrow frames and a signature hump-backed curl in their posture. They roam the #DeepSea, from the abyssal depths (3,000–6,000 m) to beyond hadal zones (>6,000 m)"

New species of octopus discovered in a deep-sea canyon csiro.au/en/news/All/News/2025

"The Carnarvon Flapjack #Octopus is a gelatinous #DeepSea octopus that grows to around 4 centimetres diameter... It's the 10th and latest #NewSpecies to be described from specimens collected during a 2022 voyage by RV Investigator... The #FlapjackOctopus is a deep-sea shape shifter with the ability to flatten its body to resemble a pancake—or flapjack—or to pull itself up to look like a tiny gelatinous umbrella."

This is my favorite exhibit at the aquarium: Into the Deep. It's special because it's also the reason why I now work at the aquarium.

I have a habit of listening to random podcasts on topics I don't know anything about, and somehow when I was job-searching last year I heard a lot of 'Monterey Bay Aquarium and MBARI and deep sea research' podcasts. With marine scientists and engineers who built the ships and tools etc.

I was like 'I want to work somewhere like that!" Looked it up, and there was a job for literally the thing that I do. At my onsite job interview, I touched a giant isopod, and I was like 'this is better than any other job I can get. I can touch a giant isopod everyday if I want.'

New Coral Gardens and Hydrothermal Vents Found in the Icy Depths of the Remote South Sandwich Islands schmidtocean.org/new-coral-gar

"recent #DeepSea expedition observed thriving polar ecosystems, discovered new #HydrothermalVents, coral gardens, and many suspected #NewSpecies... #SchmidtOceanInstitute’s RV #FalkorToo explored the #SouthSandwichIslands, including one of the coldest and most isolated submarine trenches on the planet, and also found evidence of explosive volcanism."
