Mercury stable isotope values for zooplankton collected during R/V Kilo Moana cruises KM1418 and KM1506 around Station ALOHA in 2014 and 2015 (NCEI Accession 0294373)
This dataset contains data collected on R/V Kilo Moana during cruises KM1418 and KM1506 from 2014-09-02 to 2015-05-02. These data include depth. The instruments used to collect these data include Inductively Coupled Plasma Mass Spectrometer and MOCNESS. These data were collected by Kanesa Seraphin of University of Hawaii, Brian N. Popp and Jeffrey C. Drazen of University of Hawaii at Manoa, Joel D. Blum of University of Michigan, and Claudia Benitez-Nelson of University of South Carolina as part of the "Collaborative Research: Isotopic insights to mercury in marine food webs and how it varies with ocean biogeochemistry (Hg_Biogeochemistry)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-02-24.

Supplemental Information | Acquisition Description: Zooplankton was collected using a multiple opening-closing net and environmental sensing system (MOCNESS); cod ends were fitted with a 200 micron mesh. Onboard, zooplankton were wet-sieved in filter seawater using different size mesh sieves and frozen at -20 (Degree-Celsius). The zooplankton was collected at Station ALOHA during the KM1418 and KM1506 research cruises. In the summer cruise, each tow collected material from 9 depth intervals spanning the ocean surface to 1500 m (0-50 m, 50-100 m, 100-150 m, 150-200 m, 200-300 m, 300-500 m, 500-700 m, 700-1000 m, 1000-1500 m). In the spring, four separate net tows were conducted to collected additional samples from a single depth interval (500-700 m). This was done to provide enough sample material. For total Hg (THg) determination about 10 mg of zooplankton was digested in reverse aqua regis overnight. For THg isotope determination zooplankton samples were combusted in a two-stage combustion furnace and Hg(0) g was trapped in a 1% KMnO4 solution. The 1% KMnO4 solution was analyzed for Hg stable isotope composition using a multiple collector inductively coupled plasma mass spectrometer. All the methods are detailed in Motta et al., (2019). |
