Archbold's Lake Annie is one of few subtropical lakes in the world under continuous study. It serves as a timekeeper of Florida's past, present, and future. Scientific discoveries are drawn from sediment records, monthly sampling, and monitoring buoys. Archbold collaborates with scientists around the world feeding data into regional to global networks, informing how lakes respond to change in Florida and worldwide.

Although Archbold does not have a staff limnologist, the long-term data and intrinsic values of the lake for research has attracted researchers from many countries. Students from across the USA have conducted fieldwork for Masters and PhD theses, including studies of hydrology, paleo, water quality, dissolved organic carbon, and plankton communities.

Most recently the Gaiser Laboratory at Florida International University has supported extensive graduate research on paleoecology and diatom communities. Many classes, including University of Florida and Florida International University, use Lake Annie for field courses.
