Skidaway grad students participate on glider team cruise 

From May 31st to June 5th, Skidaway Institute graduate students Kun Ma and Lixin Zhu joined a science cruise on the R/V Savannah off Cape Hatteras, N.C. The cruise was led by Jeffrey Book from the U.S. Naval Research Laboratory (NRL). The main objective of this cruise was to test and demonstrate the use of gliders together in teams and assimilate the data into ocean forecast models. The cruise was 22 days in total, divided into 3 legs. Kun and Lixin were part of the third leg.

Kun is a new Ph.D. student at Skidway, working mainly on the MoDIE project with Jay Brandes and Aron Stubbins. This was her first science cruise and she collected some particular organic matter and dissolved inorganic carbon samples. She also helped Skidaway Institute researcher Bill Savidge by collecting some chlorophyll samples in order to calibrate the chlorophyll sensor on the CTD instrument.

Lixin is a visiting Ph.D. student in Aron Stubbins’ lab. He collected filtered water samples on the cruise. He will analyze the color/fluorescence dissolved organic matter, and dissolved black carbon concentrations. In addition, Lixin performed solid phase extraction aboard and collected high-resolution real-time CDOM data using a S::CAN sensor coupled with the underway SCS system on the ship. Eventually, he will combine these data with other field data collected in the South Atlantic Bight area to see the overall dynamics of dissolved black carbon.

“I really appreciate Dr. Jeff Book for having us on this amazing cruise,” Lixin said. “I am glad that we overcame seasickness, and it’s really cool to see that the glider team controlled six gliders at the same time aboard.

“Furthermore, their working approach and decision making process, based on real-time data, modeling and satellite results, impressed me a lot. Getting some samples from such a dynamic area definitely made me really excited.”
