Please join us Thursday at 4pm in Spiess 330 for this week's AOS Seminar. We will be hearing from Dr. Grant Deane presenting "Aerosols, bubbles, and melting glacier ice: studying microscopic processes on global scales", detailed below. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Dr Grant Deane, SIO "Aerosols, bubbles, and melting glacier ice: studying microscopic processes on global scales" Climate and weather are profoundly influenced by microscopic processes occurring on global scales, driving exchanges of heat and matter between the ocean, atmosphere and cryosphere. Examples include ocean bubbles bursting to produce sea spray aerosol, bubble mediated CO2 exchange between the ocean and atmosphere, and the sound made by bubbles bursting from glacier ice, which provides a signal of ice melt rates. Parameterizing such processes is critical to inform Global Climate Models as their direct simulation on global scales lies way beyond current computational power. However, their in situ observation is extremely challenging and our knowledge of the complex feedback loops between physics, biology and chemistry at the sea surface remains limited. Analytical, numerical and experimental approaches to this problem will be presented, including examples from a recent field study of melting glacier ice in the Arctic. Progress on the Scripps Ocean Atmosphere Research Simulator (SOARS), a 2.4 m x 2.4 m x 36 m ocean-atmosphere simulator being built in the Hydraulics Laboratory at SIO will also be presented. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Please forward to any colleagues who you feel may be interested in this talk.
