This project is one of a number that are in competition for funding from the NERC Great Western Four+ Doctoral Training Partnership (GW4+ DTP). The GW4+ DTP consists of the Great Western Four alliance of the University of Bath, University of Bristol, Cardiff University and the University of Exeter plus five Research Organisation partners: British Antarctic Survey, British Geological Survey, Centre for Ecology and Hydrology, the Natural History Museum and Plymouth Marine Laboratory. It aims to provide a broad training in earth and environmental sciences, designed to train tomorrow’s leaders in earth and environmental science http://nercgw4plus.ac.uk/

Project Background

Tropical coral reef ecosystems sustain not only high levels of biodiversity, but also provide numerous ecosystem goods and services that directly benefit society. Some of these goods and services are well documented and can be quantified with increasing reliability (e.g., food resource provisioning, coastal protection). However, far more poorly quantified are rates of carbonate sand production – a process strongly influenced by reef ecology because most reef sediment derives from the fauna and flora living on reefs e.g., as a by-product of parrotfish and urchin feeding, from skeletal organisms such as molluscs and foraminifera, and from carbonate-secreting algae such as Halimeda. Data on the rates at which these producers generate sediment on reefs is generally sparse, and is especially poorly understood in relation to different types of reef settings that differ in their environmental conditions and reef community composition. This is a major knowledge gap because the quantity and grade (size) of sedimentary material produced on reefs impacts upon reef growth and is essential for proximal beach and island building.

Project Aims and Methods

The aim of this project is to parameterise and then apply methodologies for quantifying sediment generation rates, with a specific focus on remote reef-reef islands systems in Western Australia (WA). The project will build on recent approaches that have piloted methods for quantifying sediment generation based on ecological census approaches (Perry et al. 2015, 2017, 2019), and which have also started to explore the influence of disturbance events on ecologically-driven sand production (Perry et al. 2020). The student will firstly establish a set of empirical datasets to quantify rates of biological sand production for a range of sediment producing reef species (parrotfish, sea urchins, Halimeda, foraminifera) across a range of both clear-water and turbid reefs of WA (the intention being that this will include sites in Exmouth Gulf and on Ningaloo Reef). This phase of the project will include testing of AI-based tools to support auto-analysis of reef sediments for quantifying the abundance of common producers groups such as benthic foraminifera.
