Diatom collections

Diatom Flora of Britain and Ireland is a collaborative project aiming to compile a web-based diatom flora and taxonomic review of diatoms from freshwater, brackish and subaerial habitats in the British Isles.

Diatoms of North America is a collaborative effort to discover and document the diversity of diatom species across North America. We aim to provide accurate information on diatom diversity, identification, ecology and geographic distribution.

Diatom databases

DiatomBase is an attempt to integrate the Catalogue of Diatom Names, and include names that have appeared since the Catalogue of Diatom Names was last updated (2011), as well as to include information about types, ecology, images, original descriptions and distributions.

This database contains images acquired as part of the ADIAC project (= Automatic Diatom Identification and Classification), which aims at developing a fully automated, unsupervised system for the identification of diatoms. As part of this, a large reference database is required which contains “standards” that each input specimen has to be compared against. Here, we are making these images available for public use, as they are obviously also useful as a supplementary identification aid.

AlgaeBase is a global database of information on algae that includes terrestrial, marine and freshwater organisms and gives information about taxonomy, nomenclature and distribution of algae.


The Diatom Taxonomic Certification Committee (TCC) is offering a free and recorded webinar series to introduce key topics concerning diatom biology and application of diatoms to environmental science. The presentations will be made by TCC members and guests and the sessions will allow time for feedback and discussion. JOIN US!

The PAGES Early-Career Network (ECN) aims to facilitate the exchange of ideas and skill sets in order to give early-career researchers the tools to excel in their research fields. The PAGES ECN will aid in the dissemination of information, establish vital scientific networks, and foster the development of ideas that can lead to future research collaborations and improved job prospects.
