    Measurements were made of iron (Fe) and the potential for phytoplankton iron limitation on CalCOFI survey cruises (2002-2004) in coastal transition zones of the southern California Current System. This is a weak upwelling regime that is relatively low in nutrients and chlorophyll. The majority of seawater samples from the mixed layer were collected using a pole sampler, others were collected using a trace metal clean Teflon pump system. Profiles for dissolved Fe analysis were collected using GO Flo bottles attached to a synthetic line and the seawater samples were filtered under ultra-pure conditions.  Dissolved Fe was measured using an FeLume flow injection analysis system. Changes in phytoplankton (Chla response to Fe+) and nutrient parameters upon iron addition were also investigated.
