Abstract

Lead samples from 1997-2013 were collected using the MITESS (Moored In situ Trace Element Serial Sampler) moored sampler (Bell et al., 2002) (1997-2005) and ATE shipboard sampling from HOT occupations (1997-2012), the HOE-DYLAN cruises (2012), and the HOE-PhoR cruises (2013).

Lead samples from 1997-2013 were collected using the MITESS (Moored In situ Trace Element Serial Sampler) moored sampler (Bell et al., 2002) (1997-2005) and ATE shipboard sampling from HOT occupations (1997-2012), the HOE-DYLAN cruises (2012), and the HOE-PhoR cruises (2013). Samples from 1997-2000 were analyzed as described by Boyle et al. (2005) and samples after that by the method described by Lee et al. (2011). The 1997-2013 Pb samples were measured as tdPb, that is analysis of an acidified unfiltered seawater sample. Since dissolved Pb (dPb) in pelagic settings is typically >90% of tdPb (Boyle et al., 2005), the tdPb concentrations from the Station ALOHA time-series are directly comparable to the 2015 KM1513 dPb data, i.e. filtered at 0.4 μm.
