Dissolved concentrations of the trace metals Mn, Cd, Co, Cu, Ni, Zn, and Pb in vertical profile seawater samples from the upper 1,000 meters of the water column collected on R/V Roger Revelle cruise RR2004 in the south Pacific Ocean from Jan-Feb 2021

Abstract

This dataset includes dissolved (<0.4 micrometers) concentrations of the trace metals Mn, Cd, Co, Cu, Ni, Zn, and Pb in vertical profile seawater samples (upper ~1000 meters), collected on cruise RR2004 (on R/V Roger Revelle) in the south Pacific Ocean from 30 degrees South latitude to 60 degrees South along the 150 degrees West meridian. Water was collected using nine 5-liter trace metal Niskin-X bottles, suspended from Kevlar line and triggered to close with Teflon messengers. Pressure depth and temperature were determined using a data logger secured to the deepest bottle. These data are part of the NSF project "Collaborative Research: Biogeochemical and Physical Conditioning of Sub-Antarctic Mode Water in the Southern Ocean", which focused on the biological, physical, and chemical surface water properties across the polar and subpolar fronts of the south Pacific Ocean, especially as they related to the phytoplankton communities of coccolithophores and diatoms. Samples were collected by Dr. Pete Morton (Florida State University), Dr. Jule Middleton (MIT/WHOI), Dr. Logan Tegler (MIT/WHOI), and Lauren Hearn (Florida State University). Samples were analyzed by Dr. Pete Morton with assistance from Dr. Salvatore Caprara (University of South Florida-St Petersburg) at the National High Magnetic Field Laboratory.
