Canadian-built underwater observatory transmitting data from around Antarctica

A cache of scientific equipment that could fit in the back of an SUV has been lowered into the sea north of the Antarctic Peninsula, and is already streaming open-source data for anyone wanting to monitor the Southern Ocean’s health. Scientists say the underwater observatory collects measurements, including temperature, oxygen concentration and chlorophyll levels, and … Read more

Why scientists say Canada’s logging industry produces far more emissions than tallied

Canada’s forestry sector is responsible for far more greenhouse gas emissions than show up in official tallies, potentially leading to policies that aren’t in line with the country’s climate goals, a new study suggests. The peer-reviewed study, published in the academic journal Frontiers in Forests and Global Change, found that annual greenhouse gas emissions attributable … Read more

The Rocky Mountains conjure up images of grey rugged peaks capped with white. But within the upper reaches of the harsh mountain landscapes, a rosier hue often blooms. Watermelon snow, also known as glacial blood, is caused by algae that turns the snow a startling shade of red. The algae blooms in summer, forming on … Read more
