An episode of fog during 8–9 January 1996 over the Schirmacher Oasis of East Antarctica was investigated. It revealed that the fog was formed due to advection of southeasterly winds by high moisturecontaining northwesterly winds, blowing from the ocean over the cold ice shelf, which leads to the condensation of moisture, thereby forming fog for a duration of about 24 h. A monostatic acoustic sodar recorded the episode, which revealed the thickness of fog layer up to an altitude of about 300 to 400 m. Supplementary meteorological and radiosonde data were utilized to understand the mechanisms of the formation and dissipation of advection fog in this region. Supporting literature illustrates that this type of fog is an important source of water for photosynthesis, growth, reproduction and other metabolic activities of the poikilohydric microbiotic crust inhabiting the cold, arid and dry ecosystem of the coastal East Antarctic oases.
