"Compared to surrounding oceanic waters, the team found the Southern #Seamounts supported five times higher diversity, and 30 times higher biomass, of sharks and large predatory fishes combined. There was also a significantly higher number of several threatened and near-threatened species including silky sharks"

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

The seamounts of Cape Verde: a biodiversity hotspot and a priority for marine conservation in the central-eastern Atlantic

The seamounts of Cape Verde represent enclaves of enormous ecological and strategic value for marine conservation.

#Spain announced the designation of five new #MarineProtectedAreas (MPAs) https://oceanographicmagazine.com/news/conservation-win-for-spain-as-six-marine-protected-areas-declared/

"The decision adds 17,000 km² of marine space to the country’s protected waters. The newly protected sites include some of the most biologically rich and ecologically significant areas in Spanish waters: the #seamounts of the Mallorca Channel, the pockmark fields and seamounts of the Seco de Palos, the Capbreton canyon system, the Alboran Sea banks, and the Central Catalan Coast."

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"

Undersea mountains are key 'hubs' for sharks

Undersea mountains are key locations for predators—with 41 times more sharks than the open ocean, new research shows.

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
Shallow seamounts are “oases” and activity hubs for pelagic predators in a large-scale marine reserve

Seamounts have been likened to ‘oases’ of life in the comparative 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.

Satellites reveal stunningly detailed maps of Earth's seafloors

A newly-deployed satellite has created the most-detailed map yet of the ocean floor, finding hundreds of hills and underwater volcanoes that were previously missed.

I've set up hotspots for seamounts near each of the South Atlantic islands I review. I've written about it here:

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"
