Operations Area: Mid-Atlantic Ridge

Lat/Lon: 16° 30.0′ N / 46° 35.0′ W

Depth Range: 1800 m / 4500 m

Will the vessel be operating within 200 NM of a foreign country? no

Science objectives

The science objectives are to understand the processes controlling the formation, evolution, and linking of mid-segment detachment faults, and to examine the relationship between magma supply along the ridge axis and detachment fault formation.

Science Activities

Our plan is to obtain regional multibeam bathymetry and magnetic data to understand the spreading history out to 5 Ma. High-resolution multibeam bathymetry, magnetic, CTD and optical sensor data will be collected from the autonomous underwater vehicle (AUV) Sentry, and photographs from the WHOI Towcam.  We will also complete an extensive dredging operation.
