Description

This dataset contains concentrations of aerosol trace elements collected from bulk aerosol samples on the 2015 US GEOTRACES Western Arctic Transect (USCG Healy GN01).

Methods & Sampling

A total of fourteen 3-4 day integrated aerosol samples were collected during the US GEOTRACES Western Arctic research cruise (hereafter known as GN01), which took place from 9th August to 12th October 2015 on the USCGC Healy (cruise HLY1502). The cruise track consisted of a northward transect from Dutch Harbor, Alaska, across the Bering Sea, through the Bering Strait and across the Makarov Basin to the North Pole, followed by a return transect across the Canada Basin and back across the Bering Sea to Dutch Harbor.

Bulk aerosol samples for multiple trace element analyses were collected using one of five Tisch Environmental high-volume (~1 m³ air min⁻¹) aerosol samplers (model 5170V-BL). For each deployment, 12 replicate 47 mm diameter Whatman 41 filters were loaded on open-face filter holders (Advantec MFS) installed on the aerosol sampler on a PVC adaptor plate (Shelley et al., 2015). Filters were acid-washed before use to reduce trace element blanks, following the procedure described by Morton et al. (2013). The samplers were deployed on the ship's flying bridge, ~23 m above sea level, to minimize the influence of sea spray on samples. Samplers were controlled by wind speed and direction, through a Campbell Scientific CR800 data-logger interfaced with an anemometer and wind vane set up in close proximity to the samplers, in order to eliminate contamination from the ship's stack exhaust. This setup was used to restrict sampling to periods when relative wind speed and direction were >0.5 m s⁻¹ and from within ±60° of the bow of the ship, respectively, for at least five continuous minutes.

Total aerosol was analyzed on a ThermoScientific Element2 high-resolution ICP-MS at Florida State University.

Data Processing Description

Data have been corrected for field and analytical blank. Reported aerosol trace element concentrations values have been normalized to the volume of air filtered during sample collection. Each sample collection period (n = 14) produced 36 replicate filters. Three of those filters were digested to produce three replicate measurements of total particulate aerosol concentration. Data from the three replicates were averaged and reported along with the standard deviation. Outliers and replicate samples that were below the field blank value were not included in the mean. Data are marked as described in the datasheet.

Problem Report: The air volume sampled for Event 6197 was too low to produce reliable measurements. All data from this event are marked with the Flag=4.

Notes on concentration averages:
This dataset reports all 3 replicate values, plus the average and standard deviation of replicates, for the following event numbers: 6149, 6236, 6347, 6444. These averages are averages of 3 independent filter sample digestions, except when values were excluded because:
(a) a value was lower than 3x standard deviation of filter blank, or
(b) a value varied from the mean of the other two replicates by more than a factor of three.

A single value/replicate is reported for the following events (thus there are "nd"s in the average and standard deviation columns): 6060, 6123, 6168, 6197, 6267, 6304, 6387, 6424, 6487, 6495.

Quality Flags: Quality flag definitions follow the SeaDataNet Scheme. More information on SeaDataNet flags is available from GEOTRACES at http://www.geotraces.org/library-88/geotraces-policies/1577-geotraces-quality-flag-policy and from SeaDataNet at https://www.seadatanet.org/Standards/Data-Quality-Control. In summary:
BDL - below detection limit,
0 - No QC performed,
1 - Good data,
2 - Probably good data,
3 - Probably bad data that is potentially correctable,
4 - Bad data,
5 - Value changed,
6 - Sample < blank,
8 - Interpolated value,
9 - Missing value.

BCO-DMO Processing Notes:
- replaced blanks (missing data) with "nd";
- modified parameter names to conform with BCO-DMO naming conventions;
- added ISO_DateTime_UTC columns;
- 03 June 2020: updated to v2 (GEOTRACES IDP DOoR-formatted version).
