Wetlands lose water through evaporation and plant transpiration, but separating these processes remains challenging. We compared ten methods across four Canadian moss-covered wetlands and found that no single method or methodological group consistently performed best. Performance also depended on the reference data used for evaluation. Our findings suggest comparing multiple methods to identify uncertainty and highlight the need for wetland-specific evapotranspiration partitioning approaches.

We present a novel analytical system that simultaneously measures mass loss, heat flow, gas emissions, and oxygen consumption during controlled heating. The method reveals how carbon, oxygen, and sulfur are stored, transformed, and recycled in geological materials. By providing high-resolution insights into thermal reactivity and redox processes, it helps identify hidden environmental changes and offers a powerful new tool for studying biogeochemical cycles and Earth’s environmental evolution.
