Seafloor Imagery – Mid-Atlantic Ridge

2016

Mid-Atlantic Ridge

Autosub6000

Aboard the RRS James Cook, this cruise was primarily focused on acquiring the active-source geophysical data and seafloor imagery to complement the passive recordings of microseisms made by 25 ocean-bottom seismographs (OBS).

Autosub6000 was used to collect the seafloor acoustic imagery alongside a hull-mounted swath system and gravity meter. Despite not quite performing to specification, the data and information acquired were still useful in addressing the scientific objectives.
