Sensing whales, storms, ships and earthquakes using an Arctic fibre optic cable
Abstract Our oceans are critical to the health of our planet and its inhabitants. Increasing pressures on our marine environment are triggering an urgent need for continuous and comprehensive monitoring of the oceans and stressors, including anthropogenic activity. Current ocean observational system...

Abstract Our oceans are critical to the health of our planet and its inhabitants.
