Influence of sea-salt on aerosol radiative properties in the Southern Ocean marine boundary layer

Article Abstract:

Small volatile sulphate particles are the most common type of aerosol in the marine boundary layer, while most of the aerosol mass is made up of larger sizes of sea salt particles. Mid-sized aerosols scatter the sun's radiation and so are very relevant to climatic changes. Evidence from the Southern Ocean indicates that these aerosols in the marine boundary layer contain sea-salt and these can account for most of the aerosol-scattered light.

Formation of ice XII at different conditions

Article Abstract:

A metastable, crystalline phase called ice XII has been identified, obtained from cooling liquid water to 260 K at a pressure of 0.55 GPa. The crystalline phase has a tetragonal unit cell with cell parameters a=8.276 plus or minus 0.004 A and c=4.027 plus or minus 0.004 A, resulting in a density p of 1.30 g cm(super-3). The formation of ice XII does not appear to be influenced by the shape or material of the pressure cells.
