Abstract:
The West Antarctic Peninsula (WAP) in the Bellingshausen Sea is one of the most variable environments on Earth, with significant atmospheric, oceanographic and cryospheric changes taking place since the middle of the 20th century. It has
been argued that changing ocean heat content and circulation have significantly impacted melting of the fringing ice shelves and marine-terminating glaciers over the last 30 years, but our understanding of the processes by which ocean heat is fluxed onto the WAP shelf, and the mixing and exchange that occurs on the shelf, was, until recently, remarkably limited. Over the past decade, ocean gliders have yielded important insights into both circulation and mixing. In this talk, we present results from two underwater glider studies in 2015 and 2016, which show that (a) eddies and topographically-forced flows are highly significant for the two-way flux of water across the shelf break, and (b) mixing of warm deep waters on the shelf with cold and fresh Antarctic surface waters is an important control on the delivery of heat to marine-terminating glaciers, and that the rates of mixing on the shelf are heavily modulated both by near-inertial wind forcing and by sea-floor topography. These results have important implications for the representation of circulation and mixing in regional and global models, which in turn affects sea level rise projections under future greenhouse gas emission scenarios.

Online Teaching and Learning Strategies
- Location: Online
- Contact: CITS Instructional Development
- Description: A rigorous four-week, fully online certification course that introduces faculty to the current research and best practices for online teaching and learning. Using their own discipline-specific course materials for activities, faculty will work independently, collaboratively with peers from across campus, and with Instructional Designers to design and build one unit of online instruction in a myCourses site. This unit will meet the Quality Online Course Review Rubric criteria and be a model that faculty can reference and replicate as they continue to develop their upcoming fully online course(s).
