Design, construction and characterisation of an atmospheric simulation chamber. The chamber will consist of an FEP Teflon bag (with a volume of approximately 2.6m3) and a 2kW Xenon arc lamp for photolysis.
An in-situ Incoherent Broadband Cavity Enhanced Absorption Spectroscopy (IBBCEAS) will be used to detect the presence of trace atmospheric gases. Special interest will be on Iodine emitted from a selected species of seaweed. Iodine species such as I2, CH3I and Iodine oxide radicals, IO and OIO will be monitored.
