Particulate Th-234 from in-situ pumps, including large size fraction (> 51 um) and small size fraction (1-51 um), from R/V Thomas G. Thompson cruise TN303 in the Eastern Tropical Pacific in 2013 (U.S. GEOTRACES EPZT project) (NCEI Accession 0277951)
This dataset contains chemical and physical data collected on R/V Thomas G. Thompson during cruise TN303 in the South Pacific Ocean from 2013-10-29 to 2013-12-18. These data include depth and trace metal concentration. The instruments used to collect these data include McLane Pump and Riso Laboratory Anti-coincidence Beta Counters. These data were collected by Willard S. Moore of University of South Carolina and Kenneth O. Buesseler and Matthew A. Charette of Woods Hole Oceanographic Institution as part of the "U.S. GEOTRACES East Pacific Zonal Transect (U.S. GEOTRACES EPZT)" and "US GEOTRACES Pacific Zonal Transect: Rates of supply, removal and internal cycling of trace elements and isotopes (EPZT TEI Rates)" projects and "U.S. GEOTRACES (U.S. GEOTRACES)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-07-09.

Supplemental Information | Acquisition Description: Sampling details: Super stations: approximately 24 discrete particulate Th-234 samples were collected throughout the water column. Full stations: approximately 16 discrete particulate Th-234 samples were collected throughout the water column. Hemi station: 8 discrete particulate Th-234 samples were collected from the upper 3000 m. Demi and Shelf stations: no particulate samples were collected at the demi stations and the number of depths at the shelf stations was determined by the depth of the water column. Between 5 and 8 discrete particulate Th-234 samples were collected at the shelf stations. Particulate material was collected using in situ McLane pumps (also see data from Charette and Lam groups). All data were decay corrected back to the mid-pumping times. >51 um Th-234: Mesh screens were provided by the Lam group. The whole mesh screen was rinsed onto a 25 mm silver filter and dried down. The mean volume pumped through the whole Supor mesh screens was 404 L. 1-51 u m Th-234: Whole QMAs, located below a mesh screen in the filter head housing, were provided by the Lam group and oven-dried upon recovery. A 25 mm subsample was taken from this whole filter for beta counting for Th-234. The mean effective volume for the 25 mm QMA subsample was 41 L (1042 L for entire QMA).
