JC24: Dating volcanoes on the Mid-Atlantic Ridge


Cruise diary

Saturday 7 June 2008

We completed yesterdays MAPR survey in the early hours of this morning.  So did we find what we were looking for?

The TOBI data had shown us a classic looking, neutrally buoyant plume at around 2500m depth and we have been bracketing this depth with our MAPRs. Unfortunately one of the MAPRs developed a problem during the run and shorted out (meaning that data couldn’t be read from it) and data from the other one was inconclusive.

Tonight, having got both the MAPRs functioning correctly, we have launched a second survey, parallel to, but south of, yesterdays. This is due to be completed tomorrow afternoon, check back then to see what we’ve found.

Monitoring the MAPR cable.
