What is the IDS?
The International Diatom Symposium began as the “First Symposium on Recent and Fossil Marine Diatoms” in Bremerhaven, Germany in 1970 with 15 diatomists in attendance. The informal group decided to meet on a biennial basis with meetings moving to different venues across Europe. The group grew with each of the early meetings and came to recognize the need to include both marine and freshwater researchers at the symposium. At the fifth meeting of the group, the name was changed to reflect this; the “Fifth Symposium on Recent and Fossil Diatoms” was held in Antwerp, Belgium in 1978. The meeting eventually adopted the name “International Diatom Symposium” at the 1982 seventh meeting in Philadelphia, Pennsylvania, USA. In 1986, at the Ninth International Diatom Symposium in Bristol, UK, the International Society for Diatom Research (ISDR) was formally established and has used the International Diatom Symposium to hold their biennial meetings of the Council and the Society.
The IDS continues as a biennial gathering of international diatomists with symposia venues proposed by members, subjected to member vote, and given final council approval. The Society has encouraged meetings beyond European and American venues; notable venues have included the first Asian meeting (Fourteenth International Diatom Symposium, in Tokyo, Japan), the first Australian meeting (Fifteenth International Diatom Symposium, in Perth, Australia), and a symposium held in Russia (Nineteenth International Diatom Symposium in Listvyanka, Russia).

How to apply as IDS host
In order to apply as a future IDS host, the candidate needs to contact and apply to the ISDR Secretary/Council. The next step is to turn up at the following IDS – ISDR membership assembly to propose it, to be voted. To do this, a powerpoint or video file is needed to advertise it. Once the selection has been made, you can count on the support and expertise of the former conveners. A document on meeting practices is currently being created for further support. These will be found here.
Support for students
The ISDR will support a number of travel bursaries to enable student members of ISDR to attend and present at the International Diatom Symposium. The criteria which applicants must fulfill are:
- Registered / paid student member of the ISDR
- Abstract must be submitted and accepted for either an oral presentation or poster
- Must have proof of being registered student
- Priority given to students from low- and middle-income countries
