Audrey uses microfossils (including diatoms), biomarkers and geochemical tracers preserved in sediments to reconstruct changes in climatic, environmental and oceanographic conditions on time scales spanning from decades to millennia.

Diatoms of North America relies on the financial support of our user community. We aim to build our technical content by engaging diatomists at all levels and training the next generation. We need you to reach our 2025 fundraising goal of $25,000.
