Description: Amateur diatomists have played an important role in diatom science since the discovery of diatoms by an amateur in 1703. Some of the most influential amateurs (Friedrich Hustedt, Niels Foged, and Loren Bahls, to name a few) made, or are making, significant contributions. However, amateurs often communicate by alternate outlets from professionals. By highlighting work by amateurs and describing collaborations with professional scientists, this presentation demonstrates the value of collaborations. The talk focuses on the Diatom Forum, an important online network for connecting investigations of recent and fossil diatoms and for sharing knowledge and methodologies. As technology has advanced, avid amateurs have kept pace, as will be shown by discussions and illustrations on the Forum. At the end of the talk, the discussion period will provide an opportunity for amateurs and professionals to connect, share ideas, and develop new collaborations.

Intended audience: This talk is intended for amateur and professional diatomists equally, as well as for the general public.
