The 9-inch circular glass sculpture showcases the ocean zones and habitat of the model diatom Phaeodactylum tricornutum (PT). Our model diatom PT is found in open oceans, coastal areas, and on the continental shelf (specifically, the benthic zone). PT is a pennate diatom, which refers to its elongated spindle-like shape. It can be easily grown in a laboratory setting and thrives in a wide range of environmental conditions. This characteristic makes it an excellent experimental model for biofuel studies and molecular research.
