Dissolved iron-bound and total Fe-binding humic-like substances for water column samples collected in the West Antarctic Peninsula region of the Southern Ocean on RVIB Nathaniel B. Palmer cruise NBP1608 in Sept-Oct 2016

This dataset includes the concentrations of in-situ iron bound to electroactive humic-like substances and total electroactive iron-binding humic-like substances from discrete depth profile samples collected on the NBP16-08 cruise on the RVIB Nathaniel B. Palmer in the Southern Ocean from 11 September 2016 to 10 October 2016.

This project investigates the impact of Fe-binding humic-like substances on Fe biogeochemistry near the West Antarctic Peninsula and Drake Passage. The project used depth profile samples to characterize the contributions of humic-like substances to Fe biogeochemistry across gradients in Fe, water masses, and primary productivity in the Southern Ocean. Understanding the distributions of Fe-binding humic-like substances provides insight into their contribution to Fe stabilization and helps elucidate specific sources of these ligands.
