Marine debris is a ubiquitous contaminant in the world’s oceans, and yet there exists a paucity of data on the distribution of debris in the world’s urbanized estuaries. The aim of this project is to complete a survey of debris on beaches in Sydney Harbour, examining debris types, spatial distributions and pathways. Using novel photogrammetry techniques unique to this field, data will be collected using point locations from georeferenced photograph transects. The outcomes of this project will include a model of the distribution and aggregation of marine debris and insights into the pathways of marine debris. These outcomes will clearly outline how marine debris poses a threat within Sydney Harbour and will assist with the sustainable management of this estuary.
