Short summary
Freezing can affect dissolved organic matter properties and concentrations. Nevertheless, water samples are regularly frozen for sample preservation. To test, if fast-freezing with liquid nitrogen instead of normal freezing at −18 °C can prevent changes in DOM characteristics, we compared fresh and differently frozen terrestrial water samples. We found that fast-freezing with liquid nitrogen can prevent bulk organic matter concentrations but not its spectroscopic properties.
Freezing can affect dissolved organic matter properties and concentrations. Nevertheless, water...
