Melting Icebergs: Study Methods, Dynamics & Impacts - 10.21.2010

Ben Twining
In our 5th ROLE Model webinar, scientist Ben Twining described the methods and technologies he uses to conduct research about melting icebergs in the Antarctic, including CTDs, ROVs, LSTs and UAVs. In his presentation he explained the physics that occur at the boundaries of melting icebergs and the implications for nutrients and particles as they are carried with freshwater into the surrounding denser sea waters. These nutrients in turn have implications for phytoplankton and zooplankton living there. The research team's use of a small remotely operated airplane has allowed valuable overhead observations of iceberg structure and Ben's concept map includes access to a dramatic video of one of the plane's voyages to an iceberg.

Annette deCharon, COSEE-OS Directory, talked about the components of concept maps and the challenges many people have when they begin constructing them. She shared the "Luke Skywalker" technique she uses to help people get comfortable with the mapping process and as a method for learning about each other and for team building. Attached to Annette's maps are a variety of useful and fun resources specifically designed as "warm-ups" for concept map skill-building: these include Conceptionary (a variation on Pictionary), which provides practice in thinking about complex concepts and ideas, and At the Movies, an exercise for honing linking phrases.
