This activity will not result in any data. This operation is only for personnel support for Activity MBARI GORDA2017. MBARI is the lead organization. The Principal Investigator is David Clague of MBARI; the only USGS participant is Stephanie Ross. MBARI is also the lead funding organization; USGS is funding travel for Stephanie Ross.

This work is a follow-on to a similar research cruise with MBARI in 2016 (Field Activity 2016-657-FA). Bad weather on the 2016 cruise stopped us from working on the Gorda Ridge; this 2017 cruise will tackle that missed work.

Depending on the weather, the cruise will start between 8/13 and 8/17. The plan is for 11 days of work, returning between 8/23 and 8/27.
