If you could step back to the edge of the solar system...
...and look at our atmosphere...
...what would you see?
Chemical signatures of a living planet!
- Primary production
- Nutrient cycling
- GHG production / consumption
- Influence geology, climate, chemistry, and biology of Earth

What effect will anthropogenic pressures such as climate change and coastal eutrophication have on microbial "ecosystem services"?
A "model ecosystem" in Cape Breton
A "model ecosystem" in Cape Breton
- Anoxic, sulfidic waters
- Model site for impacts of coastal deoxygenation
- Metabarcoding, metagenomics will be done soon to understand taxa present
- Student research projects characterizing this system will be built on this foundation
- Projects will support overarching research question
