Seamount microbial communities (Ecology 🏞️)

Seamount microbial communities refer to microorganisms living within the surrounding environment of seamounts. Seamounts are often called the hotspot of marine life serving as a barrier that disrupts the current and flow in the ocean, which is referred to as the seamount effect. Around 25 million seamounts are known to exist, however, th...

The #seamounts of Cape Verde are essential refuges for many species, and this study highlights the importance of a multidisciplinary approach to understanding the relationships between #geology , #oceanography , biology and socio-economic aspects

Undersea mountains are key hubs for sharks https://phys.org/news/2025-02-undersea-mountains-key-hubs-sharks.html paper: https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3003016

"#Zooplankton were twice as common at shallow #seamounts than in the open ocean, while #shark biomass was 41 times higher... #FilterFeeders may benefit from prey being blown over the peak, and the peak may also stop prey species from retreating into deeper water... Also, some predators appear to use seamounts as hubs to gather, socialize, mate or rest"

Seamounts have been likened to ‘oases’ of life in the deserts of the open ocean. This integrated study of tropical #seamounts suggests that high faunal biomass is sustained by exogenous energy inputs and that they act as aggregating 'hubs' for marine top #predators #plosbiology https://plos.io/4hqrJoY

Expedition searching for #NewSpecies in #Arctic Ocean https://geographical.co.uk/news/expedition-searching-for-new-species-in-arctic-ocean

"On board the expeditions boat, the #RVKronprinsHaakon #ResearchVessel, is a multi-disciplinary team of 36 #scientists from 15 universities and institutes whose goal is to explore and chart a series of #hydrothermal vent fields, #CarbonSeeps, #seamounts and #DeepSea ridges... With only 1,100 species currently described from the #ArcticOcean, the team is hopeful of new discoveries"

"The elusive #PricklyShark was observed during a #submarine expedition to the depths of the #CordilleraDeCoiba #seamounts, a #biodiversity hotspot and marine protected area."

Underwater Mountains Harbor Abundant Life Off Chile’s Coast

"#scientists may have discovered more than 100 #NewSpecies living on #seamounts off the coast of #Chile. The recent #SchmidtOceanInstitute expedition resulted in identifying #DeepSea #corals, glass #sponges, #SeaUrchins, #amphipods, squat #lobsters, and other species likely #NewToScience."

Four New #Seamounts Discovered in the High Seas
https://schmidtocean.org/four-new-seamounts-discovered-in-the-high-seas/

"The crew of #SchmidtOceanInstitute’s research vessel #Falkor (too) discovered four underwater mountains — the tallest of which is over 1.5 miles high — on a January transit from #CostaRica to #Chile... The seamounts were found as the technicians plotted a course to examine gravity anomalies during the transit... Underwater mountains and trenches often host #DeepSea #CoralReefs, #sponges, & #anemones"

We need to know more about inner space--the oceans of Earth. And not mess them up, because they are probably what's protecting us from our own follies. #Seamounts #oceans

Study shows that Rio Grande Rise was once a giant mineral-rich tropical island near Brazil

Red clays indicate sub-aerial exposure of the #RioGrandeRise during the #Eocene volcanic episode https://www.nature.com/articles/s41598-023-46273-y

"#RioGrande Rise, a possibly continental basaltic plateau and chain of #seamounts now #submerged in the South #Atlantic #Ocean some 1,200 km from the coast of #Brazil, was once a giant tropical island, rich in #minerals and covered with vegetation."

Microbial Magic in the Deep
https://schmidtocean.org/cruise-log-post/microbial-magic-in-the-deep/

"On this cruise... we aim to identify key ecosystem services provided by #microbial life in #seamounts, including how fluid-rock-microbial processes influence #animals of the #DeepSea... in June we deployed microbial colonization experiments at sites of fluid venting... Recovery of these on-going #seafloor experiments, as well as collecting the nearby fluids and animals is a major objective of our second visit to the Costa Rican seamounts"

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."

#Scientists discover additional healthy #DeepSea #CoralReefs and new #seamounts in the #Galápagos https://phys.org/news/2023-11-scientists-additional-healthy-deep-sea-coral.html

"The larger of the #reefs spans over 800 meters in length. The second measures 250 meters in length. They exhibit a rich diversity of stony #coral species, suggesting that they have likely been forming and. supporting marine biodiversity for thousands of years. This discovery follows the April 2023 finding of the first deep coral reefs in the #GalápagosMarineReserve"

"#Scientists examining underwater cliff ecosystems onboard #ResearchVessel #Falkor (too) using #ROV #SuBastian, have discovered 2 pristine #CoralReefs in the waters surrounding the #Galápagos. These newly identified #ColdWaterReefs are situated at depths ranging from 370 to 420 meters. The discovery expands our understanding of #DeepReefs within the #GalápagosIslandsMarineReserve"

Giant #sponge grounds of Central #Arctic #seamounts are associated with extinct seep life. By Teresa Maria Morganti et al. http://dsbsoc.org/awards-2/2023-outstanding-ph-d-thesis-paper/ @dsbsoc #DeepSea

"During #Polarstern expedition to the #CentralArctic, we discovered dense #SpongeGardens covering a chain of 3 fully ice-covered giant #seamounts extending from >4000 to 5000 m depth. The observed #bacteriosponges produce dense mats of siliceous spicules, and sponge individuals sit on remnants of past seep biomass."

Gravity Anomalies Lead to Discovery of Vast Unknown #MountainRanges Under the #Ocean
Scientists used satellites to detect surface disturbances from the gravitational pull of #seamounts, discovering more than 20,000 underwater #mountains. https://www.vice.com/en/article/n7endd/gravity-anomalies-lead-to-discovery-of-vast-unknown-mountain-ranges-under-the-ocean

#Satellite data reveal nearly 20,000 previously unknown #deepsea #mountains
The number of known mountains in Earth's oceans has roughly doubled. Global satellite observations have revealed nearly 20,000 previously unknown #seamounts, researchers report in the April Earth and Space Science
https://www.sciencenews.org/article/satellite-data-unknown-oceans-sea-mountains

Scientists have discovered more than 19,000 undersea volcanoes using new seamount maps. These unexplored volcanoes could host diverse life forms and mineral resources. They could also help us understand plate tectonics, ocean mixing, and climate change.
