Dr Amanda Hodgson

Amanda is a researcher focusing on marine megafauna within the Centre for Marine Ecosystems Research.

Background

Amanda’s core research objective is to develop innovative methods and technologies to research, monitor and conserve marine megafauna and their critical habitat. During her early career Amanda studied the behaviour of dugongs and response to human impacts (boats and pingers). She has since designed and conducted many aerial surveys to understand the distribution, abundance and habitat use of marine mammals (particularly dugongs). In 2007, Amanda was one of the first in the world to investigate the potential for using drones for fauna surveys. She partnered with Insitu Pacific Ltd (Boeing), who supplied their ScanEagle for field tests and this work demonstrated the feasibility of drone surveys and has investigated the probability of detecting marine megafauna in aerial imagery in order to transition to imagery surveys. Amanda also partners with AI experts to develop deep-learning models for processing drone images, and a photogrammetric engineer/software developer to create imagery survey tools. Amanda’s research is largely centred on dugongs, and her objective of developing innovative research techniques is motivated by the need to develop research tools that are accessible and affordable in developing / under-developed countries that form a large proportion of the dugongs’ range.
