As ships get bigger port infrastructure needs to adapt; this often results in channels, berths and swing basins being widened and/or deepened via capital dredging. Environmental risks associated with capital dredging are well understood. In recognition of these risks substantial investment has been made in recent years to progress dredging science, including via the WAMSI dredging science node, and the National Environmental Science Program (NESP).

Here we present a case study from the Port of Townsville where we have embedded emerging water monitoring techniques from these programs into capital dredge monitoring. Parameters monitored for compliance are being supplemented by multispectral light measures, providing new ways of interpreting data and partitioning drivers of change in real time. Findings from this program enable informed management approach by Port, whilst also supporting proof of concept of emerging science in real world applications.
