These investigations are directly coupled to:
- geologic framework studies , which provide a more robust interpretation of the underlying stratigraphy,
- wetland studies , that allow us to examine, for example, the hydrologic control on wetland structure, and
- paleo-eutrophication studies that can place our modern interpretations into an historic context.
We need to continue to develop a better understanding of external/internal influences on the observed responses, to be able to critically evaluate long-term trends in ecosystem health.
