Importance of the film formation at the air/sea interface for the transport and production of trace gases



FILGAS Webseite

The properties of interphase boundaries in marine environment determinde the transport of matter between the different compartments. At the same time these interfaces provide physico-chemical conditions for prefered photochemical and microbiological transformations. In order o study the impact of organic surface active material on the inhibition of gas exchange and on the production of trace gases a project was initiated, which concentrates the studies of marine and atmospheric physico- and analytical chemists, physicists and microbiologists in four subprojects:

  • Subproject 1: Kinetics of film formation and impact on the diffucion of trace gases
    (IO Warnemuende, Uni Rostock)
  • Subproject 2: Chemical characterization and reaction in surface films
    (IO Warnemuende, IfT Leipzig)
  • Subproject 3: Microbiological production of trace gases
    (IO Warnemuende, IFM-GEOMAR Kiel)
  • Subproject 4: Microphysical model for exchange processes through film-covered surfaces
    (IO Warnemuende)


Our working group is involved in two subprojects:
