Cold Spice: Double Diffusion Generated by Vertical Ice Walls at Erebus Ice Tongue and Drygalski Ice Tongue, Antarctica
Entry ID: K132_2010_2012_NZ_1

Summary
Abstract: “Ocean spice” refers to one of the great hidden mechanisms driving ocean missing. Large regions of the oceans are layered in such a way that differences in molecular characteristics between heat and the salt (technically called double diffusion) are sufficient to vigorously mix the seawater – but only in vertically confined layers. These layers form tendrils anywhere from 1 to 100 m thick and can ... View entire text
