| Title: | Harmful Algal Blooms and their long term sediment record in East Coast Tasmanian waters |

University of Tasmania - Institute of Marine and Antarctic Studies [details] |
| Description: | Unprecedented toxic dinoflagellate blooms occurred off east coast Tasmania in 2012 and 2015, 2016 and 2017. These events led to a global shellfish product recall (AUD23M loss), lengthy (4 months) closures of mussel, oyster, scallop, and rock lobster fisheries, and 4 human hospitalisations (Paralytic Shellfish Poisoning). While the causative Alexandrium dinoflagellate had been previously detected, genetic evidence suggests that blooms represent a cryptic genotype newly stimulated by climate driven increased water column stratification. We seek to characterize expected recurrent blooms in relation to Maria Island NRS hydrological conditions, and compare this with the long time (1000+ yr) ancient DNA sediment record. |

Gustaaf Hallegraeff (UTAS/IMAS) | Harmful Algal Blooms And Their Long-Term Sediment Record In East Coast Tasmanian Waters (Chief Scientist: Gustaaf Hallegraeff, IMAS/UTAS) Unprecedented toxic dinoflagellate blooms occurred off east coast Tasmania in 2012 and 2015/2016. These events led to a global shellfish product recall (AUD23M loss), lengthy (4 months) closures of mussel, oyster, scallop, and rock lobster fisheries, and 4 human hospitalisations (Paralytic Shellfish Poisoning). While the causative Alexandrium dinoflagellate had been previously detected, genetic evidence suggests that blooms represent a cryptic genotype newly stimulated by climate-driven increased water column stratification. We seek to characterize blooms from with the long time (1000+ yr) ancient DNA sediment record using novel genetic methods. |
