Cruise description

This cruise was a "shake down" cruise, the first cruise after the Tully came out of her second Vessel Life Extension, and it went amazingly well. Following the first VLE in 2006 we were expecting more delays and more problems. Lots of people worked really hard for the ship to be ready on time. The weather was also on our side, allowing us to do all our work in the allocated time.
No Trace Metal samples were collected during this cruise, and only one station (P26) was sampled for pH. Since this cruise was still considered a "pre-EXPORTS" cruise, TOC and Gels samples were collected for the University of Miami.
The regular sampling was completed using a CTD, a Rosette, the Bongo, the Multiple Plankton Sampler (MPS or Multinet), and the Ring net.
Four Argo floats (two NOVA and two ARVOR) were deployed for IOS at P9, P14, P18, and P26.
