MRI campaign summer 2007 • IO heterogenously mixed, mainly intertidal area (mixing ratios up to 30 ppt ->particle formation) • OIO/I2 below detection limit • BrO detected, also during the night (?) • Strong vertical gradient • Time Series for 5 weeks available, only IO and BrO clearly identified Mace Head Campaign summer 2007 • IO, OIO, I2 and BrO, can confirm results of earlier campaigns • Good correlation with LIF, but LIF sees higher concentrations • Also measurements of I2 and IO with CEAS, halocarbons, I atoms
