Bioavailable iron has been shown to be one of the key drivers to growth of the toxic cyanobacterium, Lyngbya majuscula. In this project, a model describing the kinetics of transformation between the various iron species that exist in natural waters will be developed and this model coupled with transport codes such that reliable predictions of the flux of bioavailable iron to Moreton Bay, its distribution in the Bay and its bioavailability to Lyngbya can be made. The impact of iron transformations on the bioavailability of phosphorus within the Bay will also be elucidated.

生物可利用的铁已被证明是有毒的蓝细菌，巨大鞘丝藻生长的关键驱动力之一。在这个项目中，将开发一个模型，描述存在于自然沃茨中的各种铁物种之间的转化动力学，该模型与运输代码相结合，以便可靠地预测生物可利用铁的通量到莫尔顿湾，其在海湾中的分布和其生物利用度到Lyngbya。铁转化对海湾内磷的生物利用度的影响也将得到阐明。
