Dataset abstract Humic acid like concentration (abbreviated HA) measured with respect to the Suwannee River Fulvic acid standards (��mol SRFA equivalent per litre). Seawater samples were collected from trace metal rosette (TMR) deployments at different depths in the water column during the Antarctic Circumnavigation Expedition (ACE). Humic acid like data from legs 1 and 2, from TMR cast numbers 3 to 16, were analysed by electrochemistry following standard additions of Suwannee River Fulvic Acid (standard 1, IHSS). This data is to support iron ligands and iron bioavailability as well as hydrolysable saccharides (TPZT) data, also collected during ACE. Dataset contents ace_humics_data.csv, data file, comma-separated values ace_humics_data_visual_summary.png, metadata, portable network graphics data_file_header.txt, metadata, text format README.txt, metadata, text format Dataset license This humics dataset from ACE is made available under the Creative Commons Attribution 4.0 International License (CC BY 4.0) whose full text can be found at https://creativecommons.org/licenses/by/4.0/

The Antarctic Circumnavigation Expedition was made possible by funding from the Swiss Polar Institute and Ferring Pharmaceuticals.
