The added weight, electricity demand and aerodynamic drag of the sensors and computers used in autonomous vehicles are significant contributors to their lifetime energy use and greenhouse gas emissions, according to a new study.

Jellyfish blooms are becoming more widespread and scientists are looking for ways to understand them better, including their impact on species like salmon that compete with them for food sources. Now, researchers at the University of British Columbia have enlisted aerial drones to track these jellyfish clusters, their behaviours, and populations in greater detail.

Scientists have for the first time captured the sounds of snapping shrimp off the Oregon coast and think the loud crackling from the snapping of their claws may serve as a dinner bell for eastern Pacific gray whales, according to new research by NOAA and Oregon State University presented here today.

Last year was a record-breaking one for Operation IceBridge, NASA’s aerial survey of the state of polar ice. For the first time in its nine-year history, the mission, which aims to close the gap between two NASA satellite campaigns that study changes in the height of polar ice, carried out seven field campaigns in the Arctic and Antarctic in a single year.

Temporary lakes and ponds emit CO₂ during all year –even when they are dry-, and dry areas are the ones emitting a larger amount of carbon to the atmosphere. This phenomenon, described now for the first time, could have an impact on the global carbon cycle that controls Earth’s climate, according to a study led by the lecturer Biel Obrador, form the Faculty of Biology of the University of Barcelona, and Núria Catalán, from the Catalan Institute for Water Research (ICRA).

A few years ago, I helped lead a ship-based expedition along south Alaska during which several scientists and noted artists documented and made art from the voluminous plastic trash that washes ashore even there. At Katmai National Park, we packed off several tons of trash from as distant as South Asia. But what made Katmai most memorable was: huge brown bears. Mothers and cubs were out on the flats digging clams. Others were snoozing on dunes. Others were patrolling.

Scientists have confirmed what native Alaskans have observed for centuries – maritime winds influence the travel patterns of northern fur seal pups. New research presented at the Ocean Sciences Meeting here today shows strong winds can potentially displace seal pups by hundreds of kilometers during their first winter migration.

Scientists agree that changes in land use such as deforestation, and not just greenhouse gas emissions, can play a significant role altering the world’s climate systems. Now, a new study by researchers at MIT and Dartmouth College reveals how another type of  land use, intensive agriculture, can impact regional climate.

Study shows direct link between healthy coral reefs and shoreline stability and field-tests an innovative risk-reduction solution that combines engineering with reef restoration.

The first time Andrea Wishart held a baby squirrel, she knew then she wanted to better understand the furry little creatures, especially their boom-or-bust behaviours.

There are plenty of reasons why these bushy-tailed critters would want to maximize the amount of food to store for the winter, especially in the harsh climates of the Yukon, where Wishart, a PhD student at the University of Saskatchewan, conducts her research.
