Your best ocean photos
Thank you for these beautiful images, in celebration of World Oceans Day 2015!
Tides, and the pull of the moon and sun
The sun and moon, shape of a beach, angle of a seabed and prevailing ocean currents, and the winds, all affect the height of the tides.

How much do oceans add to world's oxygen?
Most of Earths oxygen comes from tiny ocean plants called phytoplankton that live near the waters surface and drift with the currents.

These currents can flow faster than humans can swim. If you're going to the beach this summer, this is one video you and your kids need to watch.
Editorial: Coalfield distress
Researchers at West Virginia University found that coal mines in the northern half of the state are doing well, increasing output by 8 percent per year between 2011 and 2014. But mining in southern counties is an economic tragedy.
Southern production fell nearly half (46 percent) between 2008 and 2014, a new WVU report found. This dragged down the states total output, from 158 million tons in 2008 to 115 million in 2014 with further loss to 98 million forecast for next year.
About the same time the WVU study was released, Murray Energy and Alpha Natural Resources West Virginias two largest producers announced 1,800 more miner layoffs, and Patriot Coal filed for bankruptcy a second time.
All this adds up to grief in southern counties. Families and communities are devastated by job and income loss. Real suffering results.
The Carbon Tracker Initiative, a project of Investor Watch, warns investors that U.S. coal is in structural decline. It says 26 mining firms have failed in the past three years and 264 mines have closed. In a five-year span, coal corporation stocks lost 76 percent of their value in spite of the Dow Jones Industrial Average increasing by 69 percent during the same period, it reports.
Andrew Grant of the Carbon Tracker Initiative said: The roof has fallen in on U.S. coal, and alarm bells should be ringing for investors in related sectors around the world. ...
Why arent West Virginia leaders launching emergency strategies to cope with the snowballing economic change? Why dont they seek ways to rescue suffering counties and towns? Why do they endlessly blame coals decline on federal pollution-control laws?
On June 1, a volunteer group called United Citizens for Coal was launched in Boone County, declaring: We cant sit back and watch our communities destroyed. President Roger Horton said:
WV pols, incld ones in DC, would rather howl about Obama and EPA than help the state move away from petroleum-based economy -- and that inclds fracking for natural gas. Makes one wonder (not really) just who not only provides their bread, but butters it for them as well.
