| The Beaufort Gyre is a significant reservoir of freshwater in the Arctic. It is thought to play a key role in regulating Arctic freshwater discharge to the North Atlantic, and in recent decades its freshwater content has increased in a time of rapid Arctic change. Despite this, its exact dynamical behaviour is not fully understood. Here, we make use of an Arctic‐wide dataset of Dynamic Ocean Topography (DOT), including data under sea ice, to characterise the time‐varying extent, shape, and location of the Beaufort Gyre. We show that the gyre expanded towards the north‐west between 2003 and 2014, resulting in increased proximity to the Chukchi Plateau and Mendeleev Ridge by 2014. We find that the gyre strength and maximum DOT both respond readily to changes... |
