Macquarie Island Lake Water Chemistry 2022/23

Lake water samples collected from Macquarie Island lakes during three sampling campaigns occurring in 2022-2023. Data includes field data, lab physical parameters, anions and cations analysed at ANSTO using ICP-AES, ICP-MS and IC, stable water nitrogen and carbon isotopes analysed at ANSTO using IRMS, 3H analysed at ANSTO using liquid scintillation, FT-ICR MS analysis of DOM analysed at the National High Magnetic Field Laboratory (Tallahassee), and fluorescence analysis of DOM using an Aqualog at UNSW Sydney.These data were collected as part of the SAEF Program (Securing Antarctica's Environmental Future), run out of Monash University.
