Wave beams mix and stir the ocean to create climate

Tue, 20 Jun 2017 00:00:00 EDT

(American Institute of Physics) Waves deep within the ocean play an important role in establishing ocean circulation, arising when tidal currents oscillate over an uneven ocean bottom. The internal waves generated by this process stir and mix the ocean, bringing cold, deep water to the surface to be warmed by the sun. This week in Physics of Fluids, investigators how to tell which way internal waves will go. The proposed theory unifies several previously understood explanations of wave propagation.

Amazonia's future will be jeopardized by dams

Wed, 14 Jun 2017 00:00:00 EDT

(University of Arizona) The hundreds of hydroelectric dams proposed for the Amazon River Basin will cause massive environmental damage all the way from the eastern slopes of the Andes to the Atlantic Ocean. About one-third of the 428 dams are built or are under construction. The environmental effects will ramify throughout the river system and beyond. The largest river system on Earth, the Amazon River and its watershed cover 6.1 million square kilometers and includes nine countries.

Autumn Eurasian snow variability in response to atmospheric circulation

Tue, 13 Jun 2017 00:00:00 EDT

(Institute of Atmospheric Physics, Chinese Academy of Sciences) investigate the autumn Eurasian snow variability, intending to provide a better understanding of the factors involved in Eurasian snow changes and their impacts on the wintertime Arctic Oscillation. The study concluded that atmospheric circulation and associated changes in the land-surface state are essential factors of influence for the autumn Eurasian snow variability. This complicates the prediction of autumn Eurasian snow anomalies and their climatic impacts.

Finding new homes won't help Emperor penguins cope with climate change

Wed, 07 Jun 2017 00:00:00 EDT

(Woods Hole Oceanographic Institution) Unlike other species that migrate successfully to escape the wrath of climate change, a new study shows that dispersal may help sustain global Emperor penguin populations for a limited time, but, as sea ice conditions continue to deteriorate, the 54 colonies that exist today will face devastating declines by the end of this century.

Indonesia makes its fishing fleet visible to the world through Global Fishing Watch

Wed, 07 Jun 2017 00:00:00 EDT

(Global Fishing Watch) The second largest fishing nation becomes first to publicly share government-owned vessel monitoring system data. Visible on the Global Fishing Watch public mapping platform, the data reveals commercial fishing where it had previously been invisible to the public and other nations. The bold move by Indonesia marks a victory for transparency in one of the most opaque industries in the world, prone to illegal activity that directly impacts the global economy and the environment.
