Dataset Description

Aerosol data collected on R/V Polarstern cruise ARK-XXVI-3.


Methods & Sampling

Aerosols were sampled at a rate of 1 cubic meter per minute (1 m3/min) using the Florida State University high volume aerosol sampler (Tisch Environmental TSP TE5170V). The sampler was located on the flying deck, forward railings. Acid-washed Whatman 41, 47 mm disc (cellulose esters; W41) filters were used.

Data Processing Description

Concentrations below the detection limit are flagged as "BDL" in the data columns. Detection limits were calculated using an air volume of 1200 cubic meters. See PDF of detection limits for this dataset.

Quality flag definitions:
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 edits:
- changed Aug and Sept to 08 and 09 in month columns;
- replaced blanks with 'nd' to indicate 'no data';
- modified parameter names to conform with BCO-DMO naming conventions;
- removed % signs from RSD columns.

Description
The Polarstern expedition ARK-XXVI/3 "TransArc" (Trans-Arctic survey of the Arctic Ocean in transition) served the overarching goal to capture the physical, biological and chemical state of the Arctic Ocean in a changing climate. During TransArc, investigators sampled the ocean and ice properties and their ecosystems along gradients from the Eurasian shelf edge to the Canadian Basin. Polarstern left Tromso on August 5, 2011, with 54 scientists from 10 institutes of 7 countries and 43 crew members on board. A number of ice-tethered buoys and bottom-mounted moorings were deployed and recovered respectively. Ice thickness and optical measurements were made at stations, and an ROV was deployed for under ice observations. CTD casts, plankton net casts and sediment sampling were also conducted. The station work finished on September 26. After passing the ice-free Northern Sea Route to the western Barents Sea and the stormy Norwegian and North Seas, Polarstern returned to Bremerhaven on 6 October 2011.

Project Information

Sample Analysis to Test a Novel Method of Determining Atmospheric Deposition of Trace Elements to the Ocean/Ice System of the Arctic (Be-7 Tracer Method)


Description from the NSF award abstract:
The investigators propose to use the naturally occurring isotope beryllium-7, which is produced in the atmosphere by cosmic rays and has a 53.3-day half-life, as a tracer for estimating the atmospheric fluxes of a variety of trace elements to the surface of the Arctic Ocean. They have collected samples of snow, sea ice, surface waters, and atmospheric aerosols through an international collaboration concurrent with the preparation of this proposal. This project provides funding for the analysis of Be-7 and for trace elements including aluminum, manganese, iron, cupper, zinc, cadmium, and lead. The atmospheric input of numerous chemical species into the global ocean has been shown to equal or exceed that from river sources. In the Arctic, several contaminant elements in particular are dominated by atmospheric sources, with implications for the Arctic ecosystem and human health. The project will investigate several elements of interest to the international GEOTRACES program, which is currently formulating plans for coordinated Arctic work. The project will support a Ph.D. student who will incorporate these results into his dissertation.
