Brendan Cottrell studies the application of remote sensing and drone technology in marine mammal conservation at the Applied Remote Sensing Laboratory at McGill University where he recently completed his MSc. After graduating with a BSc in applied physics from Simon Fraser University, Cottrell worked with the British Columbia Marine Mammal Response Network where he was involved in marine mammal rescue, necropsies, and research. His current research is examining the ability of drones and remote sensing techniques to characterize and catalogue the prevalence and severity of entanglement scarring on large whales such as humpbacks.
He is the first author of a new Frontiers in Marine Science article in which he and his co-authors investigated the practicality of using smartphones to create 3D scans of stranded marine life that can aid in postmortem examinations and help scientists and conservationists protect marine species.
Some of the world’s leading scientific infrastructures, institutions and experts relating to biodiversity information are uniting around a new 10-year roadmap to ‘liberate’ data presently trapped in research publications. The initiative aims to enable the creation of a ‘libroscope’ - a mechanism for unlocking and linking data from scientific literature to support understanding of biodiversity, as the microscope and telescope previously revolutionized science.
Researchers at the University of Gothenburg have discovered that what was previously thought to be a unique seaweed species of bladderwrack for the Baltic Sea is in fact a giant clone of common bladderwrack, perhaps the world's largest clone overall. The discovery has implications for predicting the future of seaweed in a changing ocean.
Hydrogen has the potential to power internal combustion engines, including on-road and off-road vehicles and equipment, and large marine engines. Despite its promise to reduce climate change emissions such as carbon dioxide and harmful pollutants, hydrogen has largely remained underutilized in the United States.
Officials at the University of Michigan and University of California, Riverside, along with several industry partners, are working to change that with the launch of the Hydrogen Engine Alliance of North America, or H2EA-NA. The alliance will promote hydrogen as a viable alternative fuel that can complement internal combustion engine, or ICE, vehicles while supporting the transition to electric and other zero emission technologies.New modeling method helped researchers understand why kelp forests returned more slowly in Southern California than in British Columbia
