Abstract:

Reconnaissance dives on seven of the New England Seamounts showed them to be rugged igneous features with pillow and massive basaltic rock exposures the dominent bottom type. A unique wall-like or radial dike was observed on two seamounts. Glacial erratics are rare on the east end of the chain but numerous on the west end. There are small bottom water currents that transport sediment sometimes causing sediment waves. There is a bottom biological population that distinctly varied from the eastern to the western seamounts. Mytilus was found to have a 300 meter shallow water coral cap rising above its volcanic base at 3,000 meters. None of the other seamounts visited on this cruise gave evidence of subsidence. Author
