Dissolved organic matter composition given as FT-ICR-MS peak intensities measured on Lena river water sample L14_29 (duplicate samples)@en

Molecular composition of dissolved organic matter (DOM) in samples collected throughout the ice-free season in the Lena River Delta. DOM was isolated from water samples using solid-phase extraction. Results from ultra-high resolution mass spectrometry are reported as relative peak intensities of a nominal mass converted to a molecular formula.
