For decades, overfishing and trawling -- dragging the ocean bottom with heavy nets -- devastated parts of an underwater mountain range in the Pacific Ocean near Hawaii, wrecking deep-sea corals and de...
Seamounts are mountains that rise from the seafloor. The technical geological definition of a seamount is a steep-sided feature with greater than 1000 m of relief compared to the surrounding sea botto...
Seamounts are windows into the deep Earth that are helping to elucidate various deep Earth processes. For example, thermal and mechanical properties of oceanic lithosphere can be determined from the f...
Seamounts play a fundamental role in facilitating the exchange of fluids, heat, and solutes between the oceanic lithosphere and the overlying ocean. Global heat flow compilations indicate that much of...
Seamounts attract the attention of physical oceanographers for a variety of reasons: seamounts play a special role in ocean biology; they may be hydrothermally and magmatically active and thereby feed...
Seamount systems that are geographically, hydrographically, topographically, and/or genetically "isolated" are likely to have developed highly endemic taxa and ecosystems. Although current estimates o...
Much interest has been generated by the discoveries of biodiversity associated with seamounts. The volcanically active portion of these undersea mountains hosts a remarkably diverse range of unusual m...
The "Subduction Factory" is a metaphor for the geochemical processing of subducted oceanic crust and sediment into components that are either incorporated into the volcanic arc or recycled into Earth'...
Extractive processes such as fishing and mining are degrading seamount ecosystems considerably, raising serious concerns about the impacts of these practices on global ocean biodiversity and key fluxe...
One of the longest seamount tracks in the Atlantic Ocean was formed by the Great Meteor or New England hotspot. This more than 3000-km-long hotspot track formed both the New England and Corner Rise se...
Graveyard Seamounts     Graveyard  Seamounts       2015/7/7
The "Graveyard seamounts" comprise a complex of 28 small volcanic edifices covering about 140 km2 (Figure 1) on the northern flank of the Chatham Rise, an oceanic plateau that extends several hundred ...
Deep-Sea Corals on Seamounts     Deep-Sea Corals  Seamounts       2015/7/7
Deep-sea corals are solitary and colonial suspension-feeding cnidarians commonly associated with seamounts around the world. They are important components of seamount ecology, providing food and refug...
Effects of Trawling on Seamounts     Trawling  Seamounts       2015/7/7
Trawling involves the towing of nets through the water or along the seafloor to sieve out fish and marine invertebrates. It is the most widely used method to catch fish throughout the world, and there...
Knowledge is key to good science and good management. But, what do you do when the information you need is scattered among hundreds of journals and reports, in dozens of languages? Or worse, data are ...
Collectively, seamounts form a significant biome the size of Europe with important but heavily depleted fisheries (see Box 12 on page 206 of this issue [Etnoyer et al., 2010]). Recently, large seamoun...
