Presentation transcript:

The Beaufort Gyre Observing System Andrey Proshutinsky and Richard Krishfield Woods Hole Oceanographic Institution GOAL: To understand the structure of the BG system, its regulating mechanisms, and impact on Arctic climate. 2003-2004 – supported by NSF 2004-2005 – supported by WHOI 2005-2009 – supported by NSF

Each component of the system stores and exchanges mass and energy differently during different climate regimes. Quantifying and describing the state and variability of these components and their coupling is essential to understand the state and fate of present day Arctic climate.
