videoRecovering the CTD in Heavy Rain

Watch as the CTD (an instrument used to measure the ocean water's Conductivity, Temperature, and Depth) is brought back aboard ship in monsoon conditions. It was really rainy and rough, but scientist Bekki Helton said she had "the time of her life." The successful recovery gave everyone a great feeling of satisfaction.


Check out these photos, which have been transmitted to the University of Delaware from the R/V Atlantis.

 

BWI Airport

There's always something to be done on a ship this size. Special K does a little priming.

SSSG techs Dave Simms (right) and Robbie Laird prepare the CTD for Bekki and Kurt's evening deployment. CTD stands for conductivity, temperature, and depth. This large array measures those three parameters continuously as it's lowered to the bottom of the ocean. The large Niskin Bottles take water samples at specific depths. Each bottle can be fired from the ship. When all the bottles are full, or the cast is done, the array is brought up onto the ship (regardless of weather).

I really thought we'd have a lot of sun while in the tropics. It's the end of the rainy season, so I expected some rain, but the crew tell me that this is the rainiest they've seen it in a long time. The up side is that the sky is a constant source of beauty; it's constantly changing and giving us something new to look at. It is sunny one minute and not five minutes later, the sky looked like this.

Dr. Andy Berglund hangs out on the bow while waiting for the sub to come up. He says he loves being here, but he misses his two girls.

Alvin suddenly resurfaces. It looks so small in the vastness of the ocean.

Jen and Lisa wait for Dave Shin's arrival in the sub. They can't wait to see his welcome.

SSSG Robbie Laird comes out of the computer room long enough to grab a bird's eye view of the recovery.

Dave looks really happy.

Until he put on his shoes and found that they had been frozen solid. Andy placed them inside the freezer (not just ANY freezer) but the –70°F freezer. They were stiff.

First-time diver Dave Shin got a special welcome.

The obligatory ice water followed the optional tomato soup. As the cruise goes on, the crew and scientists look for more and more new and intersting ways to greet the newly initiated.

Andy also left a little present in Dave shoe. This was a mussel collected Wednesday at East Wall. So it smelled bad. But Dave couldn't smell anything but tomato soup, so he opted to "mussel-model."


BWI Airport
Although Andy orchetrated Dave's arrival, Dave made sure that he left his mark. Nothing like a little tomato soup.

The fun of the greeting is a way to pass time until the moment of truth. Dr. Kevin Fielman waits to see what's in the basket.

A really large Alvinella pompejana was collected in the biobox.

The worm catch of the day. The Alvinella on the top is approximately 10 cm in length.

Dr. Stefan Sievert and Dr. Cary examine the "Mosquito." It was deployed on Wednesday, Oct. 30, and recovered on November 2. The "Mosquito" takes continuous temperature readings inside a tubeworm.

Starboard view of the sunset. I thought I'd see some colorful sunsets in the tropics; they have yet to materialize. However, the late evenings right now are spectacular in their own way.
