Daily Science Report: Thursday January 26th

The multibeam & magnetometer survey ended at 9am & we immediately launched Sentry for another ~ 24 hour survey (dive 422) on very steep terrain which exposes the dike-gabbro transition. Once again we are collecting bathymetric data, magnetic data and also “sniffing” for possible vent fluids. If we see a significant area of exposure below this transition, we’ll be back to sample with Jason. Sentry will be recovered in the morning & in the meantime we’ve continued to cut & describe the rocks we have.
