Studying Seamount Ecosystems

Multibeam sonar is an important tool for better understanding the morphology of seamounts, especially the height, which is otherwise estimated from satellite altimetry. During one mapping expedition, researchers were especially surprised to find a seamount that was 1700 meters (5580 feet) taller than estimates from satellite altimetry!
During dives on seamounts using remotely operated vehicles (ROVs), geological and biological samples are collected to better understand their history and the current ecosystems living there.
