File Cainey1.csv was created using Excel Version 5.0 and is comma delimited. It contains the Ion Chormatography results (obtained using a Dionex DX500) for four impactor samples taken at Cape Grim during ACE-1. The impactor used was an eleven stage Micro-Orifice Uniform Deposition Impactor (MOUDI). Cainey1.csv contains the sample dates, volume sampled, size ranges for each stage and the volume of water the sample was extracted in. The following ions were determined: Chloride, Bromide, Nitrate, Sulfate, Oxalate, Sodium, Ammonium, Potassium, Magnesium and Calcium. The levels of each species is given in M and nmoles/m. Non-sea-salt sulfate has also been determined using sodium and magnesium as markers for sea salt. For further information please contact jill.cainey@dar.csiro.au.
