Sea mountains are arguably the most common large geomorphological features on Earth. Most seamounts are volcanic in origin and vary in shape with size. Small volcanic seamounts are simple, typically truncated cones, whereas seamounts taller than 3km have more diverse forms due to multiple volcanic centers, flank rift zones and landsliding.

Age of Kōko Seamount, Emperor Seamount chain
Earth and Planetary Science Letters, 1973K Ar ages obtained by the conventional isotope-dilution and the 40Ar/39Ar techniques on two sanidine trachytes, four basalts, and a phonolite dredged from the top of Ko¯ko Seamount, 300 km north of the Hawaiian-Emperor bend, show that the seamount is 46.4 ± 1.1 my old.

Atlas of the Mediterranean seamounts and seamount-like structures
2016Seamounts are relevant seafloor structures, which may have different origins and which feature all the world oceans and they may be defined as hotspots of biodiversity, greatly affecting the productivity of the offshore ecosystems and the distribution of pelagic top predators.

Seamounts are ubiquitous undersea mountains rising from the ocean seafloor that do not reach the surface. There are likely many hundreds of thousands of seamounts, they are usually formed from volcanoes in the deep sea and are defined by oceanographers as independent features that rise to at least 0.5 km above the seafloor, although smaller features ...

“Seamount effects” in the zooplankton community near Cobb Seamount
Deep Sea Research Part I: Oceanographic Research Papers, 1996Abstract Oceanic seamounts often support large nektonic stocks. Since the mid-1950s it has been believed that this high productivity results, in part, from biological response to the physical interaction between oceanic currents and the abrupt topographic profiles represented by most seamounts.

Volcanic Islands and Seamounts
2017Recent advances in seafloor imagery systems have enabled the extensive mapping of submarine volcanic areas, depicting with unprecedented detail a large spectrum of landforms. They can be grouped in two main types: volcanic and erosive-depositional landforms, reflecting the interplay between constructive and destructive forces that control the growth ...

Sound Reflected from Seamounts in the Bermuda Seamount Chain
The Journal of the Acoustical Society of America, 1962Shots detonated in the bottom of the Northeast Trough (Gulf of Maine) were monitored at SOFAR-depth hydrophone locations on the Continental Slope off the U.S.A. and off the Antillies. Stations in line with the axis of the Northeast Trough received proportionally more shots than those that were off axis. The direct water arrival was followed by a second
