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

Major topographical features such as seamounts can cause large propagation losses which are functions of sound frequency and the type of interruption of the sound path. A 2 × 2 × 0.2-m high model of Dickens Seamount has been constructed of wood and plaster to a scale of 1:7874 and the sound shadowing in air has been studied for various source/receiver ...

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.

Publisher Summary The presence of numerous seamounts in the world's oceans, especially in the Pacific, has only become known to the scientific community in the last 50 years. This chapter deals with the current knowledge on the effects of seamounts on pelagic ecosystems, factors that influence the structure of seamount communities, the establishment,
