Sea charts and satellites: Mapping critical kelp beds along the Pacific coast
An ambitious project to map and monitor sea kelp forests along the entire B.C. coast is afoot, and scientists are using seemly disparate tools — both ancient and modern — to do it. Researchers are using centuries-old British sea charts and advanced technology, such as camera drones and satellite images, to trace shifts in the abundance and distribution of kelp beds over time, said geographer Maycira Costa. Like rainforests, B.C.’s canopy-forming kelp beds are critical and extensive ecosystems that shelter and feed a host of marine life, including juvenile salmon and marine mammals such...
