Why study past environments?
We try to understand how the atmosphere and oceans behaved in the past. By doing this, we can better document the natural range of variability in these systems. This allows us to better understand the impacts global change might bring due to increased anthropogenic forcing.
Geochemical tools for reconstructing past climates and environments:
There are many ways and methods to investigate past climates and environments. Of these methods, stable isotope geochemistry is perhaps one of the most powerful and reliable tools.
What is sclerochronology?
Sclerochronology is considered by many to be the aquatic equivalent of dendrochronology. This powerful method is helping to unlock high-resolution marine archives (e.g., corals, corallines, mollusks, otoliths) for paleoclimate and paleoecology studies. Sclerochronological techniques are commonly used in freshwater environments as well.

Maddie Mette, Al Wanamaker and undergraduate Aubrey Foulk recently returned from fieldwork in northern Norway associated with funding from NSF (Collaborative research: Exploring the role of oceanic and atmospheric forcing on Arctic marine climate from newly developed annual shell based records in coastal Norway).
