| Summary: | Aluminum dynamics in the ocean are unique given its rapid removal from the surface through adsorption onto sinking particles and its high abundance in the earth's crust. We optimized a flow injection analysis method to allow detection of the extremely low concentrations of dissolved aluminum found in the study region. Samples from the northeast Pacific have the lowest concentrations of dissolved Al found anywhere in the world’s ocean. We present dissolved aluminum data from a transect along Line P in the northeast Pacific in 2010 and 2011. Stations extend from near coastal waters, going through areas of potential eddy influence, and terminate at the historic Ocean Station Papa. Open ocean data shows concentrations an order of magnitude lower than extensive work performed in the Atlantic but overall similar trends with higher aluminum in the surface layer. The concentrations can go as low as 0.06 nmol/kg at depth and 0.36 nmol/kg in the surface. Coastal stations show elevated aluminum levels relative to the ... |
