This study looks at how the underground layers of peatlands (wetlands with layers of decaying plant matter) influence surface features like plant patterns and water areas in both northern boreal peatlands (like those found in Maine) and sub-tropical peatlands (like the Everglades). Through the use of ground-penetrating radar (GPR) to study the layers below the surface and see how things like peat thickness and soil depth affect the landscape above, such as vegetation types or water pools. They found that differences in the peat layers, like changes in decomposition, help shape surface features and may even affect how groundwater moves through these ecosystems. This research helps us understand the link between underground conditions and the surface landscape in peatlands across different regions.
