"Sampling  
 Size-fractionated particles were collected using dual-flow McLane Research
in-situ pumps (WTS-LV). More details about filter holders and deployments were
described in Lam et al. (2017) and Ohnemus and Lam (2015). At most of the
stations, two casts of 8 pumps each and two filter holders per pump were
deployed to collect samples at 16 depths throughout the water column. At super
stations, a 24-depth profile was obtained with three casts. The targeted
depths of the wire-out were verified by a self-recording Seabird 19plus CTD at
the end of the line and an RBR pressure logger attached to the pump at the
middle of the line. The RBR was used for all casts in the entire cruise
whereas the CTD was only deployed in the northbound leg due to electronic
problems. 142 mm-diameter \\\"mini-MULVFS\\\" style filter holders, with multiple
stages and baffle systems designed to prevent large particle loss and promote
even particle distribution (Bishop et al., 2012), were used. One filter
holder/flowpath was loaded with a Sefar polyester mesh prefilter (51 um pore
size) and paired Whatman QMA quartz fiber filters (1 um pore size) in series
(\\\"QMA-side\\\"). The other filter holder/flowpath was also loaded with a 51 um
prefilter, but it was followed by paired 0.8 um Pall Supor800 polyethersulfone
filters (\\\"Supor-side\\\"). A 150 um Sefar polyester mesh was placed underneath
all 51 um prefilters and QMA filters as a support to facilitate filter
handling. All filters and filter holders were acid leached before use based on
the recommended methods in the GEOTRACES sample and sample-handling protocols
(Cutter et al., 2010). QMA filters were pre-combusted at 450 \\u02daC for 4
hours after acid leaching.
 
'Dipped blank' filters, including the full filter sets (prefilter on top of
paired QMA or paired Supor filters), were also deployed at each cast. Prior to
the deployment, these filters were sandwiched in a 1 um polyester mesh filter,
placed into acid-leached perforated polypropylene containers, and attached to
a pump frame with plastic cable ties. All dipped blank filters were exposed to
the seawater for the same amount of time, processed and analyzed as regular
samples. As process blanks, dipped blank filters were used for blank
subtraction, calculations of uncertainties, and determination of detection
limits. A total of 33 dipped blank filter sets were collected and used for
blank subtraction and determination of uncertainty and detection limit (Table
3).
 
In this dataset, data reported from the 51 um prefilter are referred to with a
LPT suffix to indicate large particulate total concentrations (>51 um); data
reported from the main filters (QMA\\u20141-51 um \\u2014or Supor\\u20140.8-51
um) are from the top filter of the pair only, and are referred to with a SPT
suffix to indicate the small particulate total concentrations.
 
Analytical Procedures  
 Particulate organic carbon (POC) and particulate nitrogen (PN)  
 POC and PN sample processing was similar to what was described in Lam et al.
(2017). Samples were fumed in a desiccator with concentrated HCl and dried in
the oven at 60 \\u02daC overnight, and then pelletized with tin discs. Tin disc
encapsulated samples, from either one 25 mm-diameter punch from the top SPT
QMA filters or the entire LPT silver filters, were measured using a CE
Instruments NC 2500 model Carbon/Nitrogen Analyzer interfaced to a
ThermoFinnigan Delta Plus XP isotope ratio mass spectrometer (IRMS) at the
Stable Isotope Laboratory at University of California, Santa Cruz. Isotopic
results obtained from the IRMS were calibrated using reference materials
Acetanilide (C\\u2088H\\u2089NO). The effect of dissolved organic carbon
sorption is corrected with isotopic values of dipped blanks. The isotopic data
are expressed in the standard delta notation (\\u03b4) as per mil deviations
(\\u2030) with respect to international standards of Pee Dee Belemnite (PDB)
and atmospheric nitrogen. The precision of the internal standard (Pugel)
analyzed along with the samples in the run is 0.07\\u2030 for \\u03b413C and
0.14\\u2030 for \\u03b4\\u00b9\\u2075N.
 
Particulate inorganic carbon (PIC)  
 A UIC Carbon dioxide coulometer was used for PIC measurement. Briefly, PIC
on SPT QMA punches or 1/16 LPT QMA-side prefilter was converted to CO\\u2082 by
addition of 2 N sulfuric acid. CO\\u2082 produced is carried by a gas stream
into a coulometer cell where CO\\u2082 is quantitatively absorbed by a cathode
solution, reacted to form a titratable acid and measured based on the change
in current.
 
Biogenic silica (bSi)  
 An alkaline leach with 0.2 M NaOH at 85\\u02daC was used to leach bSi for
both size fractions prior to the measurement on a Lachat QuikChem 8000 Flow
Injection Analyzer at UCSC. A 4-h time-series leaching approach was applied to
all samples below 500 m to take into account the contribution from lithogenic
Si (Lam et al., 2017), where lithogenic Si was of significance in the overall
measurement. The intercept of all points in the time series with corrections
given volume changes in NaOH at different sampling points was calculated with
linear regression and used to best represent the bSi concentrations, assuming
bSi is completely dissolved in 1 hour and lithogenic Si is dissolved at a
constant rate during the leach (Bar\\u00e3o et al., 2015; DeMaster, 1981).
 
Particulate trace metals (pTM)  
 The digestion method of pTM is based on a refluxing method (Cullen and
Sherrell, 1999; Planquette and Sherrell, 2012) with light modifications
similar to the \\\"Piranha method\\\" in Ohnemus et al. (2014). In brief, the
Supor filter was adhered to the wall by surface tension in a 15 mL flat-bottom
screw-cap Savillex vial to avoid immersion. After 4-h refluxing at 110 \\u02daC
with an ultrapure (ARISTAR\\u00ae or Optima\\u1d40\\u1d39 grade) 50%
HNO\\u2083/10% HF (v/v) mixture, digestion acids were transferred into
secondary vials and heated to near dryness. The residue was heated in 50%
HNO\\u2083/15% H\\u2082O\\u2082 (v/v) to dryness at 110 \\u02daC. The final
residue was re-dissolved with 2 ml 5% HNO\\u2083 spiked with 1 ppb In. Two
certified reference materials (BCR-414 and PACS-2) were digested routinely
alongside the samples to assure the quality of each digestion. Sample
solutions were analyzed using an Element XR high-resolution ICP-MS (Thermo
Scientific) at the UCSC Plasma Analytical Facility. Elemental concentrations
were standardized using multi-element, external standard curves prepared from
NIST atomic absorption-standards in 5% HNO\\u2083. Instrument drift and matrix
effects were corrected using the internal 1ppb In standard and monitored using
a mixed element run standard. Concentrations were determined using external
standard curves of mixed trace elements standards.

Other instrumentation described in 'Instruments' section below.
 
Problem report:  
 (1) Wire angles during pump deployments  
 Severe wire angle for the aft operations were encountered in the operation
and wire angles of more than 20\\u00b0 during pumping were a consistent issue
in the open Arctic water. The actual depth of the pumps is calibrated
according to corrections based on the CTD and/or RBR pressure sensors.
 
(2) Questionable measurements for certain trace metals  
 Problems related with sampling methods: We used Pall Supor800
polyethersulfone filters to collect pTM particles. Those type of filters are
known to have high trace metal blanks for Chromium (Cr) (Ohnemus et al.,
2014). Particulate chromium (pCr) concentrations are not good to use unless at
shelf/slope stations, where particulate Cr concentrations in the water column
are high enough.
 
Problems related to digestion methods: Thorium (Th) data are much lower than
the values reported by Morton during intercalibration. Likely, the digestion
method we used without submerging the entire filter in the acid mixture seems
not to access all Th in the filter.
 
Problems related to ICP-MS: The median of nickel (Ni) in the LPT dipped blanks
is negative. Due to potential contamination from the Ni cone in the ICP, we
tend to have a high Ni blank in the acid blank at the beginning of the run and
it is hard to wash it off. It is less problematic for SPT Ni, as it has much
higher concentrations than LPT. Although acid blanks were carefully according
to the shifting Ni baseline, Ni concentrations in both size fractionations are
likely to be underestimations, and Ni data should be used with caution.
 
(3) Instrumental differences (in-situ pump vs. Go-Flo bottles)  
 Overall, our digestion (Sherrell refluxing) of pump samples have
consistently lower concentrations than Morton\\u2019s digestion of GO-FLO
bottle particles. Given the good reproductivity of Go-Flo replicate particles
between us and Morton lab applying different digestion protocols in each lab,
it is believed that the concentration differences observed are mainly caused
by sampling methods (in-situ pump vs. GO-FLO bottle & 0.8 um Supor vs. 0.4 um
Supor). Further investigations and intercalibrations between these two
sampling systems are needed in other ocean basins.";

"Description from NSF award abstract:
In pursuit of its goal \"to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions\", in 2015 the International GEOTRACES Program will embark on several years of research in the Arctic Ocean. In a region where climate warming and general environmental change are occurring at amazing speed, research such as this is important for understanding the current state of Arctic Ocean geochemistry and for developing predictive capability as the regional ecosystem continues to warm and influence global oceanic and climatic conditions. The three investigators funded on this award, will manage a large team of U.S.scientists who will compete through the regular NSF proposal process to contribute their own unique expertise in marine trace metal, isotopic, and carbon cycle geochemistry to the U.S. effort. The three managers will be responsible for arranging and overseeing at-sea technical services such as hydrographic measurements, nutrient analyses, and around-the-clock management of on-deck sampling activites upon which all participants depend, and for organizing all pre- and post-cruise technical support and scientific meetings. The management team will also lead educational outreach activities for the general public in Nome and Barrow, Alaska, to explain the significance of the study to these communities and to learn from residents' insights on observed changes in the marine system. The project itself will provide for the support and training of a number of pre-doctoral students and post-doctoral researchers. Inasmuch as the Arctic Ocean is an epicenter of global climate change, findings of this study are expected to advance present capability to forecast changes in regional and globlal ecosystem and climate system functioning.
As the United States' contribution to the International GEOTRACES Arctic Ocean initiative, this project will be part of an ongoing multi-national effort to further scientific knowledge about trace elements and isotopes in the world ocean. This U.S. expedition will focus on the western Arctic Ocean in the boreal summer of 2015. The scientific team will consist of the management team funded through this award plus a team of scientists from U.S. academic institutions who will have successfully competed for and received NSF funds for specific science projects in time to participate in the final stages of cruise planning. The cruise track segments will include the Bering Strait, Chukchi shelf, and the deep Canada Basin. Several stations will be designated as so-called super stations for intense study of atmospheric aerosols, sea ice, and sediment chemistry as well as water-column processes. In total, the set of coordinated international expeditions will involve the deployment of ice-capable research ships from 6 nations (US, Canada, Germany, Sweden, UK, and Russia) across different parts of the Arctic Ocean, and application of state-of-the-art methods to unravel the complex dynamics of trace metals and isotopes that are important as oceanographic and biogeochemical tracers in the sea.";

"NSF Award Abstract:
An investigator from Woods Hole Oceanographic Institution participating in the 2015 U.S. GEOTRACES Arctic expedition will collect and analyze suspended particulate matter in the Western Arctic Ocean to better understand cycling of trace elements in the region. In common with other multinational initiatives in the International GEOTRACES Program, the goals of the U.S. Arctic expedition are to identify processes and quantify fluxes that control the distributions of key trace elements and isotopes in the ocean, and to establish the sensitivity of these distributions to changing environmental conditions. Some trace elements are essential to life, others are known biological toxins, and still others are important because they can be used as tracers of a variety of physical, chemical, and biological processes in the sea. Particles are a key parameter for the GEOTRACES program because of their role as sources, sinks, and in the cycling of trace elements. Results from this study will be shared through outreach to native groups in Alaska. The project will involve training of graduate and undergraduate students.
Particle cycling in the Arctic Ocean is profoundly different from other ocean basins. Extremely low primary production in the perennially ice-covered central Arctic leads to a very weak biological pump. With little particle flux coming from above, the dominant source of particles to the Arctic Basin appears to be lateral transport from the margins, and these laterally transported particles have much higher lithogenic content than is typically found in particles in other ocean basins. The different source and composition of particles in the Arctic potentially sets up a completely different dynamic for the removal of particle-reactive trace elements and their isotopes from the water column than is currently understood. There has yet to be a comprehensive survey of the concentration and composition of suspended particles in the Arctic. In this study, the size-fractionated suspended particles will be analyzed for major phases and trace element composition, measurements needed to determine scavenging removal of particle reactive elements and provide insight into the mechanisms controlling the biological pump.";

tabledap lets you request a data subset, a graph, or a map from a tabular dataset (for example, buoy data), via a specially formed URL. tabledap uses the OPeNDAP (external link) Data Access Protocol (DAP) (external link) and its selection constraints (external link).

The URL specifies what you want: the dataset, a description of the graph or the subset of the data, and the file type for the response.

Tabledap request URLs must be in the form
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/datasetID.fileType{?query}
For example,
https://coastwatch.pfeg.noaa.gov/erddap/tabledap/pmelTaoDySst.htmlTable?longitude,latitude,time,station,wmo_platform_code,T_25&time>=2015-05-23T12:00:00Z&time<=2015-05-31T12:00:00Z
Thus, the query is often a comma-separated list of desired variable names, followed by a collection of constraints (e.g., variable<value), each preceded by '&' (which is interpreted as "AND").

For details, see the tabledap Documentation.
