GlobalHAB symposium on automated in situ observations of plankton

22/08/2022 26/08/2022

Aims and background

Harmful Algal Blooms (HABs) are affecting aquatic ecosystems and human societies. Biotoxin-producing HABs species and species causing fish mortalities are problems for aquaculture, fisheries and also for tourism. HABs have caused mortality of marine mammals and pose a threat to human health. Ecosystem-disruptive HABs and highbiomass HABs may cause anoxia in deep water and some HABs result in a decrease in coastal water quality and fouling of beaches. High-frequency in situ observations of HABs and predators of HAB species are needed to be able to understand HAB dynamics, to develop predictive models of HABs and to produce well-founded warnings for HABs. In recent years, novel in situ instrumentation have been developed for automated high-frequency HAB detection in near-real time. In addition, instruments for observing grazers, i.e. microzooplankton and multicellular zooplankton have been developed. These instruments are now being adopted in research and piloted in monitoring programmes. Some of the instruments are becoming available commercially. The aim of the symposium is to bring together experts on, and users of, automated in situ imaging systems to present methods, recent results and to share experiences. Another aim is to carry out a comparison of results when analysing plankton communities quantitatively. Young scientists are particularly encouraged to attend the symposium and a special follow-on workshop for young scientists on data processing and report/article writing.

A hybrid symposium

Part of the symposium will be available on line. An evening session is planned for presentations made by participants not on-site. Presentations from the morning sessions will be recorded and published at an IOC web site, link to be communicated later. Training sessions in the afternoons will not be recorded, but instruction videos will be published on line.
