    String acquisition_description "Sampling and Analytical Methodology:\\u00a0
 
1\\. Sampling:
 
Size-fractionated particles were collected using McLane Research in-situ pumps
(WTS-LV) that had been modified to accommodate two flowpaths (Lam and Morris
Patent pending).\\u00a0 Typically, two casts of 8 pumps each and two filter
holders per pump were deployed to collect a 16-depth profile.\\u00a0 The wire-
out was used to target nominal depths ('depth_n') during deployment. A self-
recording Seabird 19plus CTD was deployed at the end of the line for both
cruises. On the second cruise, three RBR data loggers were also attached to
pumps #2, #5, and #8 to help correct for actual depths ('depth') during
pumping. For the first cruise (KN199-4), the recorded CTD depth was near its
target depth and had a small standard deviation over the course of pumping, so
we report the target depth ('depth_n') as the final depth ('depth').\\u00a0 For
the second cruise, the target depth ('depth_n') is not the same as the final
depth ('depth'), since some casts experienced significant wire angles
(especially in the western boundary currents), so we corrected for the wire
angle based on the recorded depths in the three data loggers and terminal CTD.
\\u00a0
 
Filter holders used were 142 mm-diameter 'mini-MULVFS' style filter holders
with two stages for two size fractions and multiple baffle systems designed to
ensure even particle distribution and prevent particle loss (Bishop et al.
2012).\\u00a0 One filter holder/flowpath was loaded with a 51micron Sefar
polyester mesh prefilter followed by paired Whatman QMA quartz fiber filters.
The other filter holder/flowpath was also loaded with a 51micron prefilter,
but followed by paired 0.8micron Pall Supor800 polyethersulfone filters.\\u00a0
These filter combinations were chosen as the best compromise after extensive
testing during the intercalibration process (Bishop et al. 2012).\\u00a0 Each
cast also had a full set of 'dipped blank' filters deployed.\\u00a0 These were
the full filters sets (prefilter followed by paired QMA or paired Supor
filters) sandwiched within a 1micron polyester mesh filter, loaded into
perforated polypropylene containers, and attached with plastic cable ties to a
pump frame, and deployed.\\u00a0 Dipped blank filters were exposed to seawater
for the length of the deployment and processed and analyzed as regular
samples, and thus functioned as full seawater process blanks. \\u00a0
 
All filters and filter holders were acid leached prior to use according to
methods recommended in the GEOTRACES sample and sample-handing Protocols
(Geotraces 2010).
 
In this dataset, data reported from the 51micron prefilter are referred to
with a 'sink' suffix to indicate the sinking size fraction (>51micron); data
reported from the main filters (QMA - 1-51micron - or Supor - 0.8 micron-
51micron) are from the top filter of the pair only, and are referred to with a
'susp' suffix to indicate the suspended size fraction.
 
2\\. Analytical Methodology:
 
2.1. Opal (amorphous silica)  
 A 1/16 subsample of the top 0.8micron Supor filter, equivalent to ~30L, or
of the 51micron polyester prefilter above the QMA filter, equivalent to ~60L,
was analyzed for amorphous/biogenic Si concentrations using standard
spectrophotometric detection of the blue silico-molydate complex. We slightly
modified DeMaster\\u2019s time-series approach developed for marine sediments
to correct for the contribution of lithogenic silica to the leachate (Demaster
1981), using 20mL 0.2N NaOH at 85\\u00b0C for the leach, and taking a 1.6mL
subsample every hour for 3 hours.\\u00a0 The slope of the fit was negligible
for shallow samples but generally increased with depth of the sample, a
reflection of the increasing importance of lithogenic silica to total silica
with depth; we thus proceeded with a 1 hour incubation time for shallow cast
samples (<900m), and continued the time-series approach for deep cast samples
(>900m).\\u00a0 Dipped blank filters from both shallow and deep casts were used
to correct the Supor data.\\u00a0 For >51 micron samples on polyester
prefilters, blank corrections were made using the average failed pump values
(pumps that never turned on, or that shut off after <5% of programmed water
volume was filtered) because of anomalously high prefilter dipped blank
values.
 
The detection limit was three times the standard deviation of dipped blank
samples and was 0.26 and 0.19 micronol Si/filter for shallow and deep Supor
dipped blank subsamples, respectively, and was 1.05 and 0.35 micronol
Si/filter for shallow and deep polyester prefilter failed pump subsamples,
respectively.\\u00a0 Values below the detection limit are flagged (QF=4).
 
The mass of biogenic silica (opal) was calculated assuming a hydrated form of
silica: SiO2.(0.4 H2O) (Mortlock and Froelich 1989), or 67.2 g opal/mol bSi.
 
We use the standard deviation of the dipped blank filters used in the blank
subtraction to estimate error in the reported opal value.\\u00a0 The
appropriate filter-matched standard deviations were converted to \\u00b5g
opal/L using volume filtered and reported in the opal_susp_sd, opal_sink_sd
columns, as appropriate.
 
2.2 Total Particulate Carbon (TPC)  
 Total particulate carbon was measured using a Flash EA1112 Carbon/Nitrogen
Analyzer using a Dynamic Flash Combustion technique at the WHOI Nutrient
Analytical Facility. Suspended particles (1-51micron) were measured for total
particulate carbon using one or two 12mm-diameter punches from the top QMA
filter, representing the equivalent of 10-20L of material. For the >51micron
size fraction, particles from half or a whole 51micron polyester prefilter
were rinsed at sea with 1micron-filtered seawater onto a 25mm 0.8micron
Sterlitech Ag filter or 25mm pre-combusted Whatman QMA filter before being
dried at 60\\u00b0C.\\u00a0 A quarter of the Ag or QMA filter containing rinsed
particles was analyzed for total particulate carbon, typically representing
60-120L of material.  
 We use the standard deviation of the dipped blank filters used in the blank
subtraction to estimate error in the TPC measurement.\\u00a0 For TPC in the
suspended (0.8-51 micron) size fraction (TPC_susp), the standard deviation of
8 dipped blank or failed pump QMA filters (6.95 micronol C/filter for
QMA).\\u00a0 For TPC in the sinking (>51 micron) size fraction, the standard
deviation of 8 dipped blank filters rinsed onto Ag and onto QMA were 0.52
micronol C/filter and 0.59 micronol C/filter, respectively.\\u00a0 The
appropriate filter-matched standard deviations were converted to \\u00b5g C/L
using volume filtered and reported in the TPC_susp_sd, TPC_sink_sd columns, as
appropriate.
 
 2.3 Particulate Inorganic Carbon (PIC) and CaCO3  
 PIC was measured using one of four methods noted in data column
'PIC_method':  
 1.\\u00a0\\u00a0 \\u00a0Directly by coulometry (measurement of CO2 following
closed-system conversion of PIC to CO2 upon addition of 1N phosphoric acid to
a QMA punch or 1/16 polyester prefilter) (Honjo et al. 1995)  
 As CaCO3 from the measurement of salt-corrected Ca (using Na for salt
correction) (Lam and Bishop 2007) on a 1/16 subsample of Supor or polyester
prefilter or 2 QMA punches (2% of filter area) and measured by:  
 2.\\u00a0\\u00a0 \\u00a0ICP-MS at WHOI following a 2 hr room temperature 25%
glacial acetic acid leach, which was dried down and brought back up in 5% HNO3  
 3.\\u00a0\\u00a0 \\u00a0ICP-MS at WHOI following a 5% (0.6N) HCl leach for
12-16 hrs at 60\\u00b0C and diluted to 1% HCl  
 4.\\u00a0\\u00a0 \\u00a0ICP-AES at Boston University following a 5% HCl leach
overnight at room temperature  
 Intercomparability between methods was tested by running select samples in
replicate by different methods.\\u00a0 PIC_methods 1,2,3 had good
intercomparability.\\u00a0 There was a 20-30% offset in samples analyzed by
PIC_method=4 compared to the other methods.\\u00a0 Data from PIC_method=4 were
normalized using replicate analyses from a depth profile (GT11-8 for Supor
samples; GT11-24 for prefilter samples).\\u00a0 The resulting dataset has
improved oceanographic consistency.\\u00a0 When available, the reported error
is the standard deviation of replicate analyses (after normalization); if no
replicate analyses were made, the reported error is the standard deviation of
the dipped blank filters used in the blank subtraction for each method and
filtertype, adjusted for volume filtered. The standard deviation of the blank
subtraction was 18.3 \\u00b5g PIC/QMA filter for coulometry and 3.0 \\u00b5g
PIC/prefilter or 11.0 \\u00b5g PIC/Supor filter for ICP-MS. For ICP-AES, the
standard deviation of the blank subtraction was 190 \\u00b5g PIC/QMA filter, 61
or 12 \\u00b5g PIC/Supor filter (depending on the run), and 7.1 \\u00b5g
PIC/prefilter.
 
The mass of CaCO3 is calculated stoichiometrically from the mass of PIC (CaCO3
[\\u00b5g/L] = 100.08 g CaCO3/12 g C * PIC [\\u00b5g/L])
 
2.4 Particulate Organic Carbon (POC)  
 POC is calculated as the difference between TPC (see 2.2) and PIC (see 2.3).
Any negative numbers were set to 0.\\u00a0 Errors were propagated from those
from TPC and PIC.
 
2.5 Particulate Organic Matter (POM)  
 POM is calculated from POC (see 2.4) using a weight ratio of 1.88 g POM/g
POC (Lam et al. 2011).
 
2.6 Particulate trace metals (pTM)  
 Methods for particulate trace metal (pTM) digestion and analysis are
described in (Ohnemus et al. submitted) and briefly below.\\u00a0 Total pTM
concentrations in the suspended fraction (*_susp) were analyzed from 1/16
subsamples of the top Supor (0.8micron) filter.\\u00a0 pTM totals in the
sinking size fraction (*_sink) were analyzed from 1/8 subsamples (typically
~150L) of the QMA-side 51micron pre-filter. Pre-filter particles were rinsed
at sea onto 25mm Supor (0.8micron) filter discs using 0.2micron-filtered
surface seawater collected using clean techniques from an underway Fish system
(Bruland et al. 2005).\\u00a0 In Teflon vials (Savillex), samples were first
digested using a 3:1 mixture of sulfuric acid and hydrogen peroxide at high
heat to remove the Supor filter matrix, then dried. A mixture of HCl/HNO3/HF
acids (all acids 4N, heated to 135\\u00b0C for 4 hrs) was used to digest the
material in the remaining pellet, which was then dried, reacted with a small
amount of 50% HNO3/15% H2O2 to remove any remaining organics, dried, and
resuspended in 5% HNO3\\u00ac for analysis via ICP-MS (Element 2, Thermo-
Finnigan).\\u00a0 Elemental concentrations were standardized using multi-
element, external standard curves prepared from NIST atomic absorption-
standards in 5% HNO3\\u00ac.\\u00a0 Standard curves were fitted using weighted
least squares fits that consider instrument analytical uncertainties.\\u00a0
Data are reported in units of [nmoles per L of seawater filtered] and have had
the median of multiple (typically 12-16) dipped blank filters (analyzed using
identical methods) subtracted.\\u00a0 The detection limit of most elements was
defined as 3 times the standard deviation of 12-16 dipped blank
filters.\\u00a0\\u00a0 We define the detection limit for Ti to be one standard
deviation of the dipped blanks filters.\\u00a0 The median and standard
deviation of the dipped blank filters and detection limits for the Supor
(0.8-51 micron size fraction) and polyester prefilter (>51micron size
fraction) are reported in the following table in nmol per whole filter (NB:
filter area of 142mm filter is 158.4 cm2):
 
Table 1: Dipped (filter) blanks and detection limits for 0.8-51um samples for
142mm filters (nmol/filter) ([Table 1 PDF file](\\\\\"http://data.bco-
dmo.org/GEOTRACES/Lam/Lam_particulateComp_table1_v3.pdf\\\\\"))
 
In table 1 the errors (*_susp_error, *_sink_error) are reported as the 1-sigma
variation of propagated instrumental analytical and standard curve
uncertainties, and the variation in subtracted dipped blank filters.
 
The completeness of our digestion method for trace elements was assessed by
digesting and analyzing three certified reference materials: a freshwater
plankton CRM from the European Commision Community Bureau of Reference
(BCR-414), and two marine sediments from the National Research Council of
Canada (PACS-1 and MESS-3).\\u00a0 Certified values with their standard
deviation and recoveries from our lab with standard deviations, are presented
in the table appended at the end of this document.
 
2.7 Lithogenic material  
 Al is usually used as a tracer of lithogenic material since it is the third
most abundant element in Earth\\u2019s crust after Si and O.\\u00a0 Al has the
added advantage that its concentration does not vary much between upper
continental crust (UCC Al = 8.04% by weight) and bulk continental crust (BCC
Al = 8.41wt%), so the estimate of lithogenic mass is not very sensitive to
lithogenic source regions.\\u00a0 However, our data suggests that there is
considerable scavenged Al in particles near the coasts, which would lead to
overestimates of lithogenic mass in coastal samples.\\u00a0 We thus calculate
lithogenic mass two ways: 1) using the UCC Al concentration of 8.04% to
calculate lithogenic mass (Litho_AlUCC), and 2) using Ti, a lithogenic tracer
that appears to be less affected by scavenging (Litho_TiDust).\\u00a0 Ti has
the disadvantage of varying greatly as a function of different source regions
(e.g., UCC Ti=0.3wt% and BCC Ti=0.54wt%).\\u00a0\\u00a0 We make the assumption
that the source of the lithogenic material is from African dust, and use the
concentration of Ti and Al in aerosols collected on four samples between Cape
Verde and Mauritania (Shelley and Landing, personal communication) to estimate
a Ti composition of 0.6 wt% to estimate lithogenic mass (Litho_TiDust).\\u00a0
We estimate an uncertainty in the lithogenic mass derived from Ti of 7%, which
is the propogated uncertainty of the analytical error (1 sigma) of Ti (6%) and
the variability in the estimate of the Ti composition of the collected
aerosols (4%).\\u00a0 The Ti-based estimate (Litho_TiDust) is the one that we
use in subsequent calculations (eg., suspended particulate mass, section 2.9).
 
2.8 Fe and Mn oxyhydroxides  
 Fe and Mn in oxyhydroxides were calculated by subtracting Fe and Mn
associated with lithogenic material.\\u00a0 Unlike Al, crustal Fe, Mn, and Ti
vary as a function of crustal material, but the ratios of Fe and Mn to Ti are
less variable. We therefore use Fe/Ti = 8.736 (mole ratio) and Mn/Ti = 0.1268
(mole ratio) derived from aerosols collected on four samples between Cape
Verde and Mauritania (Shelley and Landing, personal communication) to subtract
the lithogenic contributions of Fe and Mn to derive Fe(OH)3_TiDust and
MnO2_TiDust.\\u00a0 For comparison, UCC Fe/Ti and Mn/Ti mole ratios are 10.0
and 0.1745, respectively. Variability in the Fe/Ti and Mn/Ti ratios in the
aerosols and analytical errors for Fe, Mn, and Ti were propagated to determine
the error for Fe and Mn oxyhydroxides.\\u00a0 The variability in the Fe/Ti and
Mn/Ti ratios in the aerosols was 2% and 6%, respectively.\\u00a0 Typical
analytical errors for Fe, Mn, and Ti are 3%, 3%, and 6%, respectively. We
approximate the formulae for Fe and Mn oxyhydroxides to be Fe(OH)3
(ferrihydrite approximation) and MnO2 (birnessite approximation), with formula
weights 106.9 g Fe(OH)3/mol Fe and 86.9 g MnO2/mol Mn, respectively. Negative
numbers were set to 0.
 
2.9 Suspended particulate mass \\u00a0  
 Suspended particulate mass in the sinking (>51micron) and suspended
(1-51micron) size fractions was estimated as the chemical dry weight of the
major particulate phases, which is the sum of POM, opal, CaCO3, lithogenic
material from Ti (Litho_TiDust), and Fe and Mn oxyhydroxides, and is
calculated as:  
 SPM = 100.08 g CaCO3/12 g C * PIC [\\u00b5g/L] + opal [\\u00b5g/L] + 1.88 g
POM/g POC * POC [\\u00b5g/L] + ...  
 \\u00a0\\u00a0 \\u00a0Litho_TiDust [\\u00b5g/L] + Fe(OH)3_TiDust [\\u00b5g/L] +
MnO2_TiDust [\\u00b5g/L]  
 Note that the resolution of this data is dictated by the lowest resolution
of the component parts.";

The first U.S. GEOTRACES Atlantic Section will be specifically centered around a sampling cruise to be carried out in the North Atlantic in 2010. Ed Boyle (MIT) and Bill Jenkins (WHOI) organized a three-day planning workshop that was held September 22-24, 2008 at the Woods Hole Oceanographic Institution. The main goal of the workshop, sponsored by the National Science Foundation and the U.S. GEOTRACES Scientific Steering Committee, was to design the implementation plan for the first U.S. GEOTRACES Atlantic Section. The primary cruise design motivation was to improve knowledge of the sources, sinks and internal cycling of Trace Elements and their Isotopes (TEIs) by studying their distributions along a section in the North Atlantic (Figure 1). The North Atlantic has the full suite of processes that affect TEIs, including strong meridional advection, boundary scavenging and source effects, aeolian deposition, and the salty Mediterranean Outflow. The North Atlantic is particularly important as it lies at the \"origin\" of the global Meridional Overturning Circulation.
It is well understood that many trace metals play important roles in biogeochemical processes and the carbon cycle, yet very little is known about their large-scale distributions and the regional scale processes that affect them. Recent advances in sampling and analytical techniques, along with advances in our understanding of their roles in enzymatic and catalytic processes in the open ocean provide a natural opportunity to make substantial advances in our understanding of these important elements. Moreover, we are motivated by the prospect of global change and the need to understand the present and future workings of the ocean's biogeochemistry. The GEOTRACES strategy is to measure a broad suite of TEIs to constrain the critical biogeochemical processes that influence their distributions. In addition to these \"exotic\" substances, more traditional properties, including macronutrients (at micromolar and nanomolar levels), CTD, bio-optical parameters, and carbon system characteristics will be measured. The cruise starts at Line W, a repeat hydrographic section southeast of Cape Cod, extends to Bermuda and subsequently through the North Atlantic oligotrophic subtropical gyre, then transects into the African coast in the northern limb of the coastal upwelling region. From there, the cruise goes northward into the Mediterranean outflow. The station locations shown on the map are for the \"fulldepth TEI\" stations, and constitute approximately half of the stations to be ultimately occupied.

Hydrography, CTD and nutrient measurements will be supported by the Ocean Data Facility (J. Swift) at Scripps Institution of Oceanography and funded through NSF Facilities. They will be providing an additional CTD rosette system along with nephelometer and LADCP. A trace metal clean Go-Flo Rosette and winch will be provided by the group at Old Dominion University (G. Cutter) along with a towed underway pumping system.
The North Atlantic Transect cruise began in 2010 with KN199 leg 4 (station sampling) and leg 5 (underway sampling only) (Figure 2).

The red line shows the cruise track for the first leg of the US Geotraces North Atlantic Transect on the R/V Knorr in October 2010.  The rest of the stations (beginning with 13) will be completed in October-December 2011 on the R/V Knorr (courtesy of Bill Jenkins, Chief Scientist, GNAT first leg).
