Subtropical systems experience occasional severe floods, dramatically altering the phytoplankton community structure, in response to changes in salinity, nutrients, and light. This study examined the effects of a 1:100 year summer flood on the phytoplankton community in an Australian subtropical bay – Moreton Bay – over 48 weeks, from January to December 2011. Immediately after maximum flood levels were reached on the rivers f...

Diatoms are important primary producers within pelagic, benthic, and epiphytic communities, and their siliceous frustules sink rapidly to the sediment. We measured benthic nutrient and gas fluxes and water column and sediment properties in an estuary of southeastern Australia to identify control mechanisms coupling benthic and pelagic processes, in particular, how nutrients become fractionated by processes affecting benthic nu...
