Daily Summary: We continued our expedition, collecting data for seismic Line 15, over the Diebold Knoll. During the day, we had the opportunity to deploy Expendable Bathy Thermograph (XBT), used to measure the ocean temperature and calculate a sound velocity curve to calibrate bathymetry. Halfway through our day, we were delighted to learn we were 7 hours ahead of schedule, giving us extra seismic data acquisition time. We adjusted our plan accordingly and extended Lines 21 and 22, going over Brendan’s Seep, to acquire data that would give us greater geological context for the region.
