The IOC and IAEA is proud to announce the publication of IOC Manuals & Guides no 59

This manual is intended as an introduction to basic analytical techniques that can be applied when designing a standard sampling protocol for both planktonic and benthic microalgae (and associated environmental conditions) and vectors of biotoxins (shellfish and fish). This standardization of methods will enable more robust data comparisons between countries and will yield improved risk assessments of potentially toxic HABs events.

This Manual is a joint product of the IAEA and the IOC of UNESCO. The IAEA and the IOC express their profound gratitude to the highly committed editors Beatriz Reguera (Spain), Rosalba Alonso (Mexico), Ángel Moreira (Cuba), Silvia Méndez

(Uruguay), who also contributed as authors; to the expert authors that prepared the original manuscript in Spanish and the updated version in English: and to Laura-Victoria Perdomo and Andrés-Leonardo Malagón (Colombia), Jaime Espinoza (El Salvador), and Leonel Carrillo (Guatemala) who revised the first (Spanish) edition; to Patricia Tester (USA) as a new co-author of chapter 3 in this second (English) edition, and to Mireille Chinain (French Polynesia) and Rachel Clausing (IAEA) who contributed with a new chapter 8 for this second edition.

This publication was funded under the US Peaceful Use Initiative within the framework of the International Atomic Energy Agency (IAEA) Technical Cooperation Project RAS7026 and through IOC UNESCO Regular Programme for the Harmful Algal Bloom Programme. The International Atomic Energy Agency is grateful to the Government of the Principality of Monaco for the support provided to its Environment Laboratories.
