The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Dissolved REE concentrations from the US GEOTRACES Arctic cruise (GN01, HLY1502) from August to October 2015 (NCEI Accession 0291443) |
| Abstract: | This dataset contains data collected on USCGC Healy during cruise HLY1502 in the Arctic Ocean, Bering Sea, and Chukchi Sea from 2015-08-14 to 2015-09-28. These data include depth. The instruments used to collect these data include Inductively Coupled Plasma Mass Spectrometer, Niskin bottle, and SeaFAST Automated Preconcentration System. These data were collected by Leopoldo D. Pena Gonzalez and Steven L. Goldstein of Lamont-Doherty Earth Observatory, Brian Haley of Oregon State University, and Howard Scher of University of South Carolina as part of the "Collaborative Research: GEOTRACES Arctic Section: Nd isotopes and REEs in the Arctic (Arctic GEOTRACES Nd/eNd)" and "U.S. Arctic GEOTRACES Study (U.S. GEOTRACES Arctic)" 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 2021-01-25. The following is the text of the dataset description provided by BCO-DMO: Dissolved REE concentrations from LDEO Dataset Description: This dataset contains data from samples analyzed at Lamont-Doherty Earth Observatory (LDEO). Additional dissolved REE data are reported by Oregon State University (OSU) in a separate dataset (see 'Related Datasets'). |

| Supplementary information: | Acquisition Description: Samples were filtered, acidified, and split at sea. Samples were collected by Niskin bottle. Refer to the cruise report for more information on cruise operations ( http://dmoserv3.whoi.edu/data_docs/GEOTRACES/Arctic/ARC01-report.pdf ). For REE concentration analyses, aliquots of 50 mL were taken from each sample. About 12 mL of each sample was then weighed and 30-300 mg of a mixed REE spike enriched in ¹⁴²Ce, ¹⁴⁵Nd, ¹⁴⁹Sm, ¹⁵³Eu, ¹⁵⁵Gd, ¹⁶¹Dy, ¹⁶⁷Er, and ¹⁷¹Yb was added. Samples were then preconcentrated offline using a SeaFast PICO system (ESI) following the methodology described in Behrens et al., 2016 and Wu et al., 2020. Resulting solutions were analyzed at Lamont Doherty Earth Observatory (Palisades, NY) using a Nu Attom ES HR-ICP-MS. |
