A WHOI “D2” ocean-bottom seismograph is field-tested on the seafloor near the TAG hydrothermal vent site in the North Atlantic. The seismometer is housed in the silver canister at right; a weight anchors it to the bottom. The instrument records details of earthquakes on the seafloor for up to a year, including very faint tremors that are difficult to detect and analyze from shore.
