About isa SEAweed

The International Seaweed Association (ISA) welcomes you to its web site. The ISA is an international organisation dedicated to the encouragement of research and development of seaweed and seaweed products.

One of the main activities of the ISA is the organisation of a 3-yearly International Seaweed Symposium of which 20 have now taken place all over the world. The 22nd Symposium took place in Copenhagen in 2016 and the next will be in Korea in 2019.

The Proceedings of Symposia are published on behalf of the ISA under the general title of “Proceedings of the International Seaweed Symposium”. More recently, selected papers presented at symposia are published by the Journal of Applied Phycology.

Mission & Vision

The mission of the ISA is to promote applied phycology on a global basis, and to stimulate interactions among research workers and industrialists in all relevant institutions and industries in all countries. Within this mission, the objectives of the ISA are primarily directed towards seaweeds, but also include other algae including cyanobacteria, as well as algal constituents.

The Gordon and Betty Moore Foundation has launched a new area of research, the Symbiosis in Aquatic Systems Initiative. Over the next nine years, we will invest $140 million to support development of new tools, theory and concepts about aquatic symbioses and to bring different research communities together to learn how symbioses involving microorganisms function, evolve and serve critical ecosystem roles in marine and freshwater environments.
** We have a call for applications open for individual investigators with a deadline of June 3, 2019. Application website: https://symbiosis.smapply.io/. Additional funding opportunities will be announced soon. **
