The bottles on the CTD start out open. Marine technicians help the scientists send the CTD over the side of the ship. Then scientist work together with the ships crew to lower to the CTD to however deep we want to go. On this we had one CTD go down to 5000 meters… thats over 3 miles down!! Then we begin to bring the CDT back up and when we get to a depth that we want a sample from, we stop the CTD and flip a switch that closes the bottles. When the CTD is back on board, we use spouts to collect the water. The CTD also has many complicated instruments on it that tells us the temperature, how salty the water is, and how much chlorophyll is in the water. It is a very cool instrument to work with!

Watch a video of a CTD at work HERE.

Thanks,

Much of the bacteria in the deep oceans are very similar to the bacteria that are in the surface ocean and on land. But because the deep ocean is what we call an “extreme environment” (because it is very cold, very dark, and their is a lot of pressure), we are also discovering bacteria that do things in very different way. For instance, many bacteria live off of the chemicals that come out of undersea volcanoes. Very cool!
Thanks,
Steve Tuorto

What have you learned so far about the chemistry and microbiology of what lives in the deep oceans?
