The ISSHA website is constructed with the idea of providing an interactive platform to promote research, dissemination and communication on Harmful Algae issues.

ISSHA is the International Society for the Study of Harmful Algae. Read more on About us and check out our facebook site.

The site has an events calendar for upcoming conferences, job ads, and links to Harmful Algal Bloom (HAB) websites that will be of interest to the international community of HAB researchers, managers and to the news media.

Members may access a Membership List, a Members' Discussion Forum, and a Members' Upload Page to upload articles, thesis abstracts, reports, documents, obituaries, and/or information on how to get them. After logging in, these are available via the SOCIETY navigation button.
