Abstract

These data include dissolved iron (Fe) concentrations and stable isotope ratios (δ56Fe relative to IRMM-014) from water column samples collected during four Bermuda Atlantic Iron Time-Series (BAIT) cruises (GApr13) in the Bermuda Atlantic Time-series Study (BATS) region in March, May, August, and November 2019. Analyses were carried out at the University of South Florida.

The primary data file "936824_v1_bait_dissolved_fe_and_isotopes.csv" includes data from all four cruises. Data from each cruise is also provided separately in the attached Supplemental Files (csv format). The Supplemental Files include the unique GEOTRACES barcodes assigned to each parameter from each cruise. These barcodes are used by the GEOTRACES program for data tracking purposes.
