Palmer Station VERTEX-style Sediment Trap measurements, 50 m depth, 2012-2013

Measurements were made using moored VERTEX-style particle interceptor tube (PIT) sediment traps deployed at a depth of 50-m at stations B and E near Palmer Station between Nov. 2012 and Apr. 2013. Sediment trap contents was measured to determine fluxes of POC, PN, and Th-234 on two size fractions (>200 and <200 micron). Note that these are operational size classes and may not directly coincide with the size of aggregates that may have been sinking in the water column. For more details, please see Stukel et al. (in review, Global Biogeochemical Cycles).
