US ocean observation critical to understanding climate change, but lacks long-term national planning

Fri, 20 Oct 2017 12:57:58 EDT ~ Ocean observing systems are important as they provide information essential for monitoring and forecasting changes in Earth's climate on timescales ranging from days to centuries. A new report finds that continuity of ocean observations is vital to gain an accurate understanding of the climate, and calls for a decadal, national plan that is adequately resourced and implemented to ensure critical ocean information is available to understand and predict future changes.

Life goes on for marine ecosystems after cataclysmic mass extinction

Fri, 20 Oct 2017 09:22:26 EDT ~ One of the largest global mass extinctions did not fundamentally change marine ecosystems, scientists have found. Find out more...

Climate shifts shorten marine food chain off California

Thu, 19 Oct 2017 17:16:37 EDT ~ Environmental disturbances such as El Nio shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant over time. Find out more...

Maintaining fish biomass the key to conserving reef fish biodiversity

Thu, 19 Oct 2017 10:10:29 EDT ~ A new study has found that conserving fish diversity in Madagascar's coral reef systems may depend on maintaining fish biomass above critical levels. Find out more...

Scientists see order in complex patterns of river deltas

Thu, 19 Oct 2017 10:10:21 EDT ~ River deltas, with their intricate networks of waterways, coastal barrier islands, wetlands and estuaries, often appear to have been formed by random processes, but scientists see order in the apparent chaos. Find out more...

Fossil coral reefs show sea level rose in bursts during last warming

Thu, 19 Oct 2017 10:09:54 EDT ~ Scientists have discovered that Earth's sea level did not rise steadily when the planet's glaciers last melted during a period of global warming; rather, sea level rose sharply in punctuated bursts. Find out more...

Ice stream retreats under a cold climate

Thu, 19 Oct 2017 10:08:02 EDT ~ Warmer ocean surface triggered the ice retreat during The Younger Dryas. Find out more...

Keratin, proteins from 54-million-year-old sea turtle show survival trait evolution

Tue, 17 Oct 2017 09:18:57 EDT ~ Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provides direct evidence that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.

Waves in lakes make waves in the Earth

Mon, 16 Oct 2017 08:19:50 EDT ~ Scientists report that small seismic signals in lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake. Find out more...

Giant sea bass worth more alive as undersea wonders than as commercial catch

Sat, 14 Oct 2017 11:16:23 EDT ~ An investigation of the different economic values of giant sea bass finds they are worth more alive as undersea wonders than as commercial catch. Find out more...
