Polar Geoengineering: A Risky Experiment That Will Not Fix Climate Change

Earth’s climate is warming because we burn fossil fuels for electricity, transport, heating, and food production, and this releases greenhouse gases. The polar regions (the Arctic and Antarctic) are w...

Preliminary results are in: Fixed-wing drones show strong potential for moose surveys.

Monitoring moose populations has been traditionally done by helicopter. Our partners at UBC are exploring if drones are a better alternative.

Model generalisation & transferability 🛰️ We tested 2 setups (A & B) to see when site-specific models beat generic ones. Expanded discussion on limitations + showed how data augmentation can boost robustness as a proof-of-concept.

U-Net models were trained & validated with spatial block CV, including both site-specific and generic models across all sites, to produce more realistic and transferable evaluations. Random CV inflated performance estimates by up to 28%.
