Tales From a Grad Student: Shallow Overturning Circulation

Julius Busecke

Graduate Research Assistant
Columbia University

Julius Busecke is a Ph.D. candidate at Lamont-Doherty Earth Observatory, Columbia University. He received his B.Sc. from the University of Kiel, Germany in 2010. His interests include the ocean's role in the global freshwater cycle, mixing and transport by ocean eddies, and the influence of ocean eddies on the oceanic surface variability.

Webinar Clip
Julius Busecke is interested in ocean circulation but more specifically, something known as shallow overturning circulation. In this clip, Julius explains what that is and uses the North Atlantic Ocean, home of SPURS (Salinity Processes In the Upper Ocean Regional Study) as a case study. He also gives viewers a glimpse at some preliminary results gleaned from a recent cruise to the SPURS.

Applicable Science Standards
  • Asking Questions and Defining Problems Asking Questions and Defining Problems. A practice of science is to ask and refine questions that lead to descriptions and explanations of how the natural and designed world(s) works and which can be empirically tested.
  • Using Mathematics and Computational Thinking Using Mathematics and Computational Thinking. In both science and engineering, mathematics and computation are fundamental tools for representing physical variables and their relationships. They are used for a range of tasks such as constructing simulations; solving equations exactly or approximately; and recognizing, expressing, and applying quantitative relationships.
  • Constructing Explanations and Designing Solutions Constructing Explanations and Designing Solutions. The goal of science is the construction of theories that provide explanatory accounts of the world. A theory becomes accepted when it has multiple lines of empirical evidence and greater explanatory power of phenomena than previous theories.
