Seamounts are exceptionally important to their biome ecologically, but their role in their environment is poorly understood. Because they project out above the surrounding sea floor, they disturb standard water flow, causing eddies and associated hydrological phenomena that ultimately result in water movement in an otherwise still ocean bottom ...
Seamounts are often called the hotspot of marine life [1] [2] serving as a barrier that disrupts the current and flow in the ocean, which is referred to as the seamount effect. [3] [4] Around 25 million seamounts are known to exist, [2] [4] [5] however, the research on microbial communities are focused on volcanically active seamounts.
A sheet flow more than 3 km (2 mi) long and 500 to 800 m (1,640 to 2,625 ft) wide was produced from Axial Seamount's upper southern flank, on the site of what was formerly an active geothermal field. The southern flows were in an area marked by a difference between older sediments and newer, glassier rock, and the maximum ridge generated by the ...
Seamounts enhance water flow through localised tides, eddies, and upwelling, and these physical processes may enhance primary production. [36] Seamounts may therefore be considered as hotspots of marine life; fauna benefit from the enhanced hydrodynamics and phytoplankton supply, and thrive on the slopes and summits.
Seamounts are underwater mountains usually formed from the remnants of extinct volcanoes. The giant structure measures 5,249ft (1,600m), making it twice the height of the Burj Khalifa in the ...
Studies have indicated that a seamount functions as an "oasis of life," with a higher species count and more biodiversity than the surrounding seafloor. [4] Although previous analysis has stressed the exceptionalism of the seamount habitat, recent biological analysis, much of it centered on Davidson Seamount, has indicated that this does not necessarily translate into a higher endemic percentage.
A seamount is a mountain rising from the ocean seafloor that does not reach to the water's surface (sea level), and thus is not an island, islet or Cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
Adams and the other seamounts were created by the Pitcairn hotspot, and these seamounts are its present-day location. [3] This hotspot is one among several hotspots in the Pacific Ocean, along with the Austral hotspot, Hawaii hotspot, Louisville hotspot, Samoa hotspot and Society hotspot. [6] The seamounts rise from a 30 million years old crust ...
