DescriptionDiatoms – single-celled algae – are abundant in both fresh and salt waters and are among the most common types of phytoplankton. By some estimates diatoms are responsible for one-fifth of the photosynthesis on earth. Diatom cell walls are hard due to a high proportion of silica. Their geometric shapes are diverse and beautiful, and they are incredibly durable, persisting for hundreds of millions of years in the right matrix. Because they have different ecological requirements, the kinds, mixture and relative abundance of diatoms is an exceptional tool for the study of ancient marine and freshwater environments and their change through time.

Christof Pearce of Aarhus University, working with colleagues at Utrecht University and the Geological Survey of the Netherlands, studied the diatoms preserved in a 79cm-long core of peat sediment from Highlands Hammock state park in central Florida to reveal a 2,500-year history of the area's hydrology. They discovered a new diatom species, Aulacoseira coroniformis, which proved important for reconstructing aspects of the site's ecological history.
