Tubeworms at Cloud Vent.

ROPOS dive 622 was in the water for 24 hours and returned with a record number of 46 samples from the seafloor. Of the 46 samples, 24 were from the vent fluid sampler, 14 were miniature temperature recorders that were recovered from last year, and the remaining 8 were suction samples. More...

R/V Wecoma - CTD Cruise

Part of the excitement of going to sea is discovering what's going on in the hidden world below. Last year we left five moorings on the seafloor here to monitor hydrothermal plumes, and today we'll recover them to see what secrets they hold. Since we can only visit Axial once a year, we must depend on instruments to provide information on changing hydrothermal conditions between cruises. More...

NOAA Ship Ron Brown - Jeff Goodrich

Suddenly ROPOS appears from the dark abyss below. ROPOS's huge winch is almost finished with the laborious task of raising the vehicle for the hour and a half that it takes to reach the surface. It slowly coils the metal cable around and around. The seven person deck crew is ready to retrieve and safely get the ROV back on deck. More...

R/V Wecoma - Missy Holzer

So what happens to those water samples from the Nisken bottles on the CTD? Yesterday you heard about the "fish" that we have deploying and recovering from the R/V Wecoma. Today we will explore what happens after the fish has been recovered as well as what occurs in the chemistry lab on board the ship. More...

Participant Perspective

Interview with George White
Executive Officer NOAA Ship Ron Brown

Jeff: What are your duties as an executive officer on the Ron Brown?

George: The executive officer is second in charge out here. It's kind of like vice-president. I oversee all the administration of the ship. Anything from pay to benefits, orders, travel, or human resources issues. I work directly with the chiefs of the departments and oversee the officers and junior officers on board about personnel issues, fitness reports and leave. Traditionally the captain and the executive officer stay separate from the daily watch standing duties but in modern times we operate on a minimum manning staffing. So, the captain and I both stand watch. That's fun because it keeps your hands in the daily events. Otherwise you get tied up with paperwork and lose track of the ship's operations. More...
