Depleted seamounts Hawaii decades protection
2019/10/21
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...

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'...
Can We Protect Seamounts for Research?A Call For Conservation
Protect Seamounts Call For Conservation
2015/7/7
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...

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 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...
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...
