When ice forms, salt contained in the water is returned to the ocean, less the salt retained in the ice itself. When ice melts, the salt contained is added back to the ocean.

The parameterisation is often seen as essential in Arctic ocean simulations even in high resolution models. The improvments it provide to an ORCA1-LIM simulation is shown in Wang and Holloway (OM, 2009).
