A #Seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock.

Because of their abundance, seamounts are one of the most common marine ecosystems in the world.

Oregon’s most active underwater volcano could erupt this year,
according to a prediction recently shared by scientists.

The #Axial #Seamount,
located 300 miles from the state’s coast and one mile beneath the Pacific Ocean’s surface,
has been swelling at a steady rate for the past six months,
with seismic activity totaling hundreds of earthquakes per day,
according to an Oregon State University blog that chronicles eruption predictions of the sea volcano.

In November, scientists were tipped off about the possibility of an imminent explosion
when Axial’s surface swelled to nearly the same height it had risen to in 2015
—just before it last erupted.

"The team mapped a 1.9-mile tall #seamount, which is part of the #NazcaRidge, an underwater mountain range in the southeast #Pacific Ocean. The potentially #NewSpecies, which have yet to be officially confirmed, include a sea urchin, starfish and a squat lobster."

Yeah, I probably have to eat my words. My volcano-tracking app doesn’t include any active seamounts that aren’t on plate boundaries, so it very likely could be missing others. This very well could be an undersea volcanic eruption.

"We then apply such scalings to a global #seamount dataset and an ocean climatology to show that seamount-generated mixing makes an important contribution to the upwelling of deep waters. Our work thus brings seamounts to the fore of the deep-ocean mixing problem and urges observational, theoretical, and modeling efforts toward incorporating the seamounts’ mixing effects in conceptual and numerical #ocean circulation models"

Massive New #Seamount Discovered in International Waters Off #Guatemala
https://schmidtocean.org/massive-new-seamount-off-guatemala/

"The 1,600-meter seamount covers 14 square kilometers and sits 2,400 meters below sea level... This marks the ninth #seafloor #discovery since the #ResearchVessel #Falkor (too), was launched in March... #Seamounts are #biodiversity hotspots, providing surfaces for #DeepSea #corals, #sponges, and a host of #invertebrates... There are more than 100,000 #unexplored seamounts taller than 1,000 meters."

"The measures will protect #CabliersBank, the only cold-water #CoralReef known to be growing in the #Mediterranean... Cabliers Bank is a #seamount that harbours semi-pristine species such as #DeepSea white #corals and offers shelter and nursery for several commercial stocks such as Norway #lobster and blackspot #seabream. The coral mound is over 400,000 years old."

"Five weeks after setting sail from #Tromsø, #Norway, the @awi #ResearchVessel #Polarstern makes a stop at the northernmost point on Earth. Here, too, the international team of #researchers is investigating the coupling between #SeaIce, the #ocean and its life, including within the #DeepSea... the team has discovered an amazing #biodiversity at a previously unmapped #seamount at 1500 meters depth, under the ice."

"The team of scientists analysed data from visits by Japanese mining engineers to the Takuyo-Daigo #seamount. A year after the test extraction, researchers observed a 43% drop in #fish and #shrimp density in the “deposition” areas directly affected by #sediment #pollution, and a 56% drop in surrounding areas.
“It is easy to assume that once you are outside the zone of deposition there will be no impacts from #mining,” said Washburn"
