Summary of measurements

-At station: Mooring a reference magnetometer to correct diurnal variations.
-Underway measurements: 3.5 kHz Seabeam; Digital single-channel seismics; Gravimetry; Magnetism.
-International cooperation: embarking on RV Meteor (Germany) to explore an area of the Mohns Ridge (taking rock and sediment samples, video filming), based on mapping produced from Mohns Ridge 1.
