Details

Dr. Xiaojun Yuan fires a XBT temperature and depth probe over the rail of the Oden in the Drake Passage. The expendable sensor measures water temperature and depth as it plunges toward the bottom. A coil of copper wire unrolls behind the sensor and transmits data back to the ship as the probe sinks. Each XBT sensor can only be used once but it is much less expensive than using the large CTD sensor that requires the ship to come to a stop for over an hour as a crew of people use a crane to lower the sensor package over the side and return it to the ship. Aboard the icebreaker Oden.

Being a scientist really appealed to me because I was really excited about the opportunity to be curious about the world and to try to answer questions that interested me about the natural world.

One of the most challenging things about being a teacher is to get students truly interested in what they're learning.

One of the most rewarding things about being a scientist is the discovery of new knowledge. You get to go out and ask questions that nobody has asked before, use your imagination to see the world around you and become excited about discovering new knowledge and new ideas.
