Sediment flux determined via sediment traps at marine sites around Davis Station, East Antarctica, summer 2009/10.

No preservatives were used to keep the settling particles. Upon collection the sediment trap contents were transferred to acid cleaned 200 mL HDPE bottles. Collected sediment material was transported to the laboratory at Davis Station and stored at 4 degrees C until processed (within 48 hours of collection).

All plastic ware and filters were acid cleaned in a 10% nitric acid bath, rinsed with Milli-Q and dried prior to use. Sediment material was twice filtered through pre-weighed 0.8 micron glass fibre filters and 0.45 micron cellulose acetate filters. Filters were then placed on individual petri dishes, oven dried at 60C, cooled in a desiccator and their dry weights recorded.
