A front forms in northern Baffin Bay (~75.25°N) between Atlantic-derived water carried by the West Greenland Current and Arctic-derived waters exiting southward through Nares Strait and Jones Sound via the Baffin Current. Subsurface waters (e.g. below 100 m) of the West Greenland Current are as much as 2°C warmer than those of the Baffin Current. Confluence of these waters leads to a frontal transition between 100-500 m wherein cross-frontal gradients of potential temperature (Δθ/ΔL ~ 0.06-0.07 °C.km-1) and salinity (ΔS/ΔL ~ 0.005-0.007 PSU.km-1) are largely density compensating (Δσθ/ΔL ~ 0.001 km-1). Subsequent thermohaline interleaving establishes conditions conducive to mixing via cabelling and double-diffusion. The front's location would allow it to play a contributing role in the formation of Baffin Current water structure and eventual export of freshwater to the North Atlantic.
