AB  - There is growing public concern about the global expansion of harmful algal bloom 
      species (HABs), with dinoflagellate microalgae comprising the major portion of 
      the harmful taxa. These motile, unicellular organisms have a lifecycle involving 
      sexual reproduction and resting cyst formation whereby cysts can germinate from 
      sediments and 'seed' planktonic populations. Thus, investigation of 
      dinoflagellate cyst (dinocyst) distribution in sediments can provide significant 
      insights into HAB dynamics and contribute to indices of habitat quality. Species 
      composition and abundance of dinocysts in relation to sediment characteristics 
      were studied at 18 stations in two densely populated temperate Australian 
      estuaries, Sydney Harbour (Parramatta River/Port Jackson; PS) and Botany Bay 
      (including Georges River; GB). Eighteen dinocyst taxa were identified, dominated 
      by Protoceratium reticulatum and Gonyaulax sp.1 in the PS estuary, together with 
      Archaeperidinium minutum and Gonyaulax sp.1 in the GB estuary. Cysts of 
      Alexandrium catenella, which is one of the causative species of paralytic 
      shellfish poisoning (PSP), were also detected in both estuaries. Out of the 
      measured sediment characteristics (TOC, Cd, Cr, Cu, Fe, Pb, Mn, Ni, Zn and 
      polycyclic aromatic hydrocarbons), TOC was the parameter explaining most of the 
      variation in dinocyst assemblages and was positively correlated to most of the 
      heavy metals. Given the significant relationship between sediment TOC and 
      dinocyst abundance and heavy metal concentrations, this study suggests that 
      sediment TOC could be broadly used in risk management for potential development 
      of algal blooms and sediment contamination in these estuaries.
