Abstract

The nourishment of carbonate beaches on coral reefs is reliant on the continual growth of calcareous organisms, and subsequent deposition on beaches. While understanding both production and deposition are both important, to date, there is a limited understanding of the dynamics that link these two processes. Large benthic foraminifera (LBFs) are unicellular organisms which calcify on coral reef algal flats and contribute >95% of carbonate beach sediments in certain locations. For this seminar, I will 1. present data collected on Lizard Island Reef to understand how substrata affect calcification rates of LBFs in current and near-future climate change scenarios of global climate change and ocean acidification. 2. I will present further syntheses of these data to understand how reef-scale carbonate production rates on Lizard Island Reef are projected to be altered by climate change. 3. Lastly, I will discuss current plans to refine both source production modelling efforts using metabolic scaling and sink deposition efforts through geospatial modelling.
