Atlantic ports unite to protect marine ecosystems with eDNA innovation

Four Atlantic ports — Saint John, Halifax, Summerside, and Corner Brook — have joined forces to advance marine ecosystem protection through the Atlantic Ports Baseline Biodiversity Initiative. The initiative will make use of environmental DNA (eDNA), a cutting-edge method that facilitates monitoring biodiversity without disrupting the environment.

The project is being led by the Halifax Port Authority through the PIER, its centre for port development and innovation, and brings together an impressive group of collaborators that include research and innovation partners Genome Atlantic, IGNITE Atlantic, the PEI Marine Science Organization, along with eDNA specialists Dartmouth Ocean Technologies (DOT) and eDNAtec.

Sampling began in 2024, with three to five sites in each port monitored regularly using traditional Niskin bottles. The ports of Halifax and Saint John are also piloting an automated sampling system developed by DOT.

The initiative aims to track biodiversity patterns across time and geography, ultimately improving the condition of nearby marine environments. It supports the continuing efforts by the Green Marine certified ports of Halifax, Saint John, and Summerside to advance their efforts within the program’s Aquatic Ecosystems performance indicator.

With recognition from the World Ports Sustainability Program, the initiative reflects a growing commitment to transparent, science-based environmental action. It also reinforces engagement by Atlantic Canadian ports in adopting more sustainable and innovative approaches to their operations.
