Diatom communities are a popular tool for monitoring environmental conditions, past and present, and are commonly used in studies of water quality.

Subsequently, the number of ESTs was extended to 12, 000 and the Diatom EST Database was constructed for functional analyses.

Diatom cells repeatedly and reliably manufacture valves of various shapes and sizes, potentially allowing diatoms to manufacture micro-or nano-scale structures which may be of use in a range of devices, including: optical systems ; semiconductor nanolithography ; and even using diatom valves as vehicles for drug delivery.

The Diatom Herbarium also provides collections and taxonomic services for the Phycology Section of the Patrick Center for Environmental Research.

Because of their expertise and their close working relationship with the Academy's Diatom Herbarium, the Phycology Section of the Patrick Center is able to provide algal analyses for governmental and other agencies interested in both assessing water quality and long-term environmental trends.

This view still might be contrasted with deep ecology, which holds that an intrinsic value is attached to all forms of life and nature, whether currently assumed to be sentient or not.
