  • The sampling programme was carried out successfully using kites and helium balloon assisted kites to sample in both low and higher winds speeds. Air samples were successfully processed using the Ice Nucleus chamber for a variety of wind directions representing a range of air mass trajectories and source regions. The aim was to sample air that had passed over land (the Peninsula), sea (Bellingshausen and Weddell) or ice (the plateau) and compare the size and quantity of ice crystals transported. Air filters and ice crystal replication slides have been returned to the laboratory for analysis.

  • Data was collected via Automatic Weather Station (AWS), an ADAS tether sonde system, some radiosondes, a sensor and logger attached to the ice-crystal replicator system and an Ice Nucleus chamber. The collection was made during a month-long period in January and February, 2002, at a site east of Weatherheaven.The data are documented with a detailed diary, a summary of weather observation and a summary of data collection dates and hours.
