Measurements of brine diffusivity in both vertical and horizontal directions to 1400 mm in sea ice from McMurdo Sound
Entry ID: K131_2002_2003_NZ_1

Abstract: Nuclear magnetic resonance (NMR) techniques for probing sea ice cracks and imperfections and the use of this as a tool for wide ranging surveys of sea ice properties was investigated over several seasons. A probe is lowered into an angular cut made in the sea ice and measurements of brine diffusion are made. NMR uses the earth's magnetic field to obtain a sign from the liquid brine which is ...
