deployed from surface ships and manned submersibles. 

 Sequential sampling sediment traps that can collect data year 

 round and multi-chambered fluff layer traps that can work at the 

 sedimentwater interface are but two examples of technically 

 advanced tools needed to advance hypotheses about the fate of 

 POM. Staging missions in spring and early summer periods when 

 primary production is likely to peak in the mixed layer will 

 permit assessments of POM flux.
