Wind-driven freshwater buildup and release in the Beaufort Gyre constrained by mesoscale eddies†
Recently the Beaufort Gyre has accumulated over 20 km3 of freshwater in response to strong anticyclonic atmospheric winds that have prevailed over the gyre for almost two decades. Here, we exploreExpand
Climate impacts of intermittent upper ocean mixing induced by tropical cyclones
[1] Tropical cyclones (TC) represent a powerful, albeit highly transient forcing able to redistribute ocean heat content locally. Recent studies suggest that TC-induced ocean mixing can have globalExpand
Analysis of the Beaufort Gyre Freshwater Content in 2003–2018
TLDR
Despite significant uncertainties in the different observations, this study has demonstrated the synergistic value of having multiple diverse datasets to obtain a more comprehensive understanding of Beaufort Gyre freshwater content variability. Expand
A Theory of the Wind-Driven Beaufort Gyre Variability
The halocline of the Beaufort Gyre varies significantly on interannual to decadal time scales, affecting the freshwater content (FWC) of the Arctic Ocean. This study explores the role of eddies inExpand
Submesoscale Sea Ice-Ocean Interactions in Marginal Ice Zones
Signatures of ocean eddies, fronts, and filaments are commonly observed within marginal ice zones (MIZs) from satellite images of sea ice concentration, and in situ observations via ice-tetheredExpand
Generation and Separation of Mesoscale Eddies from Surface Ocean Fronts
AbstractThis study is motivated by Arctic Ocean observations of sub–mixed layer eddies found at large distances from their assumed formation region of a surface ocean front. Eddy formation isExpand
Enhanced eddy activity in the Beaufort Gyre in response to sea ice loss
TLDR
The authors found that dramatic loss of sea ice and acceleration of surface currents after 2007 led to a net annual wind energy input to the Beaufort Gyre, and anticipate that continued sea ice decline will lead to an increasingly energetic BeaufortGyre with eddies playing a greater role in its stabilization.

Robust ENSO across a Wide Range of Climates
AbstractEl Nino–Southern Oscillation (ENSO) is a pronounced mode of climate variability that originates in the tropical Pacific and affects weather patterns worldwide. Growing evidence suggests thatExpand
Pathways of ocean heat towards Pine Island and Thwaites grounding lines
TLDR
An unprecedentedly high-resolution ocean model is used that resolves shelf-sea and sub-ice-shelf environments in qualitative agreement with existing observations during austral summer conditions and demonstrates that the waters reaching the Pine Island and Thwaites grounding lines follow specific, topographically-constrained routes.
