A54C:
Marine Aerosols and Trace Gases II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 16285

Session Description:
Particulate - sea salt and organic matter - and gaseous - sulfur and halogen -  emissions from the oceans affect the formation, number concentration, and composition of cloud condensation nuclei (CCN) and ice nucleating particles (INP), and influence the reactive chemistry, budgets, and lifetimes of climate-active gases. This session invites contributions in the general areas of (1) laboratory studies, field experiments, and satellite studies of the production, chemical characterization, and optical properties of sea spray, sea-surface micro layer composition, measurements of gaseous halogens and DMS, and aerosol photochemistry; (2) regional and global scale modeling of sea spray and ocean-derived trace gases; (3) development of innovative instrumentation relevant to air-sea aerosol/gas exchange. Contributions from recent field campaigns leading to process-level understanding of entrainment of aerosol from the upper troposphere and removal mechanisms (both dry and wet deposition) are also encouraged.
