Dataset Overview | National Centers for Environmental Information (NCEI)

Concentration of atmospheric aerosol total mercury (Hg) from R/V Knorr cruises KN199-04 and KN204-01 (GA03) in the Subtropical northern Atlantic Ocean from 2010-2011 (U.S. GEOTRACES NAT project) (NCEI Accession 0277930)

Graphic not available.

This dataset contains chemical data collected on R/V Knorr during cruises KN199-04 and KN204-01 from 2010-10-15 to 2011-12-09. These data include metal concentration in atmosphere. The instruments used to collect these data include Aerosol Sampler and Cold Vapor Atomic Fluorescence Spectrophotometer. These data were collected by Carl Lamborg of Woods Hole Oceanographic Institution and Chad Hammerschmidt of Wright State University as part of the "U.S. GEOTRACES North Atlantic Transect (U.S. GEOTRACES NAT)" project and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2021-05-11.

The following is the text of the dataset description provided by BCO-DMO:

Concentration of atmospheric aerosol total mercury (Hg) from the 2010 and 2011 U.S. GEOTRACES cruises.

Dataset Description:
This dataset includes concentrations of atmospheric aerosol total mercury across the North Atlantic Zonal Transect.

Supplemental Information	Acquisition Description: In general, the cruise path was contained from 15 to 40 N and 19 to 70 W. Aerosols were collected by Tisch high-volume aerosol sampler mounted on the 03 deck of the R/V Knorr, forward of the main stack. Sampling was sector-controlled to collect air only arriving at the ship from over the bow, to avoid sampling stack gases and debris associated with science activities on the back deck. Samples were frozen and transported to Woods Hole Oceanographic Institution (Woods Hole, MA) where they were analyzed within 3 months of collection. The filter swaths that were provided were digested in acid-cleaned polypropylene containers with 5 mL of 2N HNO3, heated to 60 degrees C and sonicated. Following digestion, 1 mL of BrCl was added directly to the digestate (Lamborg et al., 1995, Morton et al., in press). Total mercury analysis: - Fitzgerald & Gill, 1979, Bloom & Fitzgerald, 1988, Bloom, 1989. - Tekran Model 2500 CVAFS Mercury Detector - Detection limit: 50 fmoles - Procedural duplicates: 3 ± 2 percent r.s.d. (n=24) - Results are presented in filter- and reagent-blank corrected form.
