Description

Norwegian Cruise Line partnered with NatureMetrics to launch the cruise industry's most extensive marine environmental DNA (eDNA) monitoring program across Alaska's pristine waters. This groundbreaking initiative transforms cruise vessels into floating research platforms, collecting water samples during routine operations to identify marine species through their genetic traces. The program addresses critical ocean conservation needs by monitoring biodiversity, detecting invasive species, and supporting threatened species protection. Operating along the Inside Passage route, the initiative combines advanced molecular science with sustainable tourism, creating unprecedented opportunities for guest education while contributing vital data to global conservation efforts including the IUCN Red List database. NCL is now extending the sampling across more of its cruise routes filling global ocean data gaps.

Impact & Result

Detected 670+ marine species (endangered Sea Otters, Ocean Sunfish, and threatened Steller Sea Lions). Data contributed to IUCN conservation database, enabling protection strategies for at-risk species. Early warning system for invasive species detection across 9 cruise routes annually. Citizen science experiences, improved ESG reporting compliance (CSRD ESRS E4), and positioned NCL as sustainability leader generating competitive advantage and increased customer loyalty.

Solution Spotlight

eDNA enables data on species and ecosystems to be generated at unprecedented scales using DNA traces that organisms leave behind in the environment, especially in water. A simple kit is used to filter water from lakes, rivers or oceans, capturing the DNA traces the filter membrane, which is sent to a laboratory for analysis. In the lab, the DNA is sequenced and sequences are compared against a reference library to identify the species they came from. A single sample of just a litre of water can reveal hundreds of species, ranging from bacteria to blue whales and including both species that live in the water and those living on land nearby. The ease of sampling enables biodiversity to be surveyed in more places, more often, and by a wider range of stakeholders, providing the evidence-base for effective conservation, impact mitigation and restoration of our natural resources.
