Cold Suns, Warm Exoplanets and Methane Blankets

CarlSagan_20080903-full.jpg

Three billion years ago, the sun shone weaker, but Earth stayed surprisingly warm. Carl Sagan thought a greenhouse effect must have been to thank. A model built on 359 chemical processes has finally arrived at scenarios with a reasonable chance of producing enough methane to do the trick.

New Research Shows Hydropower Dams Can Be Managed Without an All-or-Nothing Choice Between Energy and Food

Nearly 100 hydropower dams are planned for construction along tributaries off the Mekong River’s 2,700-mile stretch. In Science Magazine, researchers present a mathematical formula to balance power generation needs with needs of fisheries downstream.

Brittle Starfish Shows How to Make Tough Ceramics

A coral reef-dwelling starfish that creates highly resistant lenses from chalk has given an international team of researchers a biostrategy that could lead to new ways for toughening brittle ceramics in applications including optical lenses, automotive turbochargers and biomaterial implants.

Final Check as Instruments Set Sail to Track Aerosols Over Southern Ocean

icebreaker-720px.jpg

Imagine spending several weeks aboard a ship traversing the stormiest ocean on Earth, climbing each day to the highest deck to check on scientific instruments mounted inside a windowless, 20-foot shipping container. As you steady yourself against the rolling seas by wedging your body between instrument racks, you might wonder why you’re not sitting poolside on a tropical cruise instead.

In Churchill today, the federal government, through Western Economic Diversification Canada, announced a significant investment to assist Canadians with the cost of food and to generate economic growth, particularly in northern Manitoba.

Marine Invertebrates Have Noisy Human Neighbors

Dossot_ASA_Figure1copy.jpg

Marine invertebrates are impacted by the rising levels of underwater noise produced by humans, but the production of underwater noise is not only difficult to control, but the direct effect on marine invertebrates can be challenging to observe or measure. Researchers will present results on the use of a standing wave tube to simulate and measure the effects of anthropogenic noise on marine invertebrates at the 174th ASA Meeting, Dec. 4-8, 2017, in New Orleans.

Fish Exposed to Treated Wastewater Have Altered Behaviour: Research

IMG_12122.jpg

A team of researchers from Environment Canada and Climate Change Canada and McMaster University have found that fish living downstream from a wastewater treatment plant showed changes to their normal behaviour—ones that made them vulnerable to predators—when exposed to elevated levels of antidepressant drugs in the water.

Submarine Volcanoes Add to Ocean Soundscape

ASA-fall-2017-Tepp-volcano.jpg

Most volcanoes erupt beneath the ocean, but scientists know little about them compared to what they know about volcanoes that eject their lava on dry land. Researchers think that with improved monitoring, they can learn more about these submarine eruptions, which threaten travel and alter the ocean soundscape. During the 174th ASA meeting, held Dec. 4-8, 2017, in New Orleans, Gabrielle Tepp of the USGS will discuss the challenges and benefits of remote monitoring and what it can teach about submarine volcanoes.
