Some Corals May Be Resistant to Climate Change, Researchers Say

Publication: NBC News   Date: April 24, 2014   View Article

A new study on how coral reacts to global climate change has some researchers optimistic that at least a few of the polychromatic reefs crucial to underwater ecosystems may be better able to adjust to a warming world than was previously thought.

That’s good news, given that coral reefs soften the blow of storms headed to areas where people live, and nurture a kaleidoscopic array of fish that provide a livelihood and food for people around the globe.

But coral reefs aren’t out of hot water yet.

The Next Exxon Valdez? Remote Alaskan Waters, Experts Fear

Publication: NBC News   Date: March 24, 2014   View Article

A quarter-century after 10.8 million gallons of crude oil gushed from the Exxon Valdez and scarred Alaska’s Prince William Sound, oil spill responders fear that another disaster looms in more remote Alaskan waters where ship traffic is on the rise, due in part to the North American energy boom.

The largest concern centers on the Arctic, where oil exploration and development is progressing in fits and starts, and Unimak Pass in the Aleutian Islands, a choke point on a major shipping route between North America and Asia. Both regions are expected to see increased traffic as summer sea ice disappears and producers of North American crude oil and coal look to export fossil fuels to Asia.

Five distinct humpback whale populations identified in North Pacific

Five distinct populations of humpback whales ply the North Pacific Ocean each year between winter breeding and summer feeding grounds, according to a new study. The finding adds a layer of complexity to ongoing efforts to conserve the majestic marine mammals.

Humpback whales are found throughout the world’s oceans. In the North Pacific, they number more than 21,000 today, up from less than 1,000 at the end of commercial humpback whaling in 1966. “That is a great thing,” Scott Baker, a marine biologist with Oregon State University’s Hatfield Marine Science Center in Newport, told NBC News.

Google Earth spies unreported fish traps, study reveals

Fishing traps known as weirs that jut from coastlines may be snaring six times more fish in the Persian Gulf than what is officially reported, according to a new estimate based, in part, on satellite imagery available through Google Earth.

Scientists turned to the Internet search giant’s mapping tool as a way to cross-check catch data reported to the United Nations Food and Agriculture Organization by six countries in the gulf, a region of the world where marine ecosystems are understudied.

Cold-water fish food not adapting to a warming world, study says

Tiny sea creatures that play a big role in the ocean food chain are unable to adapt to warming oceans, according to a new study that may have profound ramifications for fisheries.

The cold-water plankton lives for one year or less. Researchers examined a 50-year dataset from the North Atlantic to determine how this creature and another plankton that thrives in warmer water fared over half a century.

Deep-sea Internet to detect tsunamis, spy on smugglers, and discover oil

Publication: NBC News   Date: October 15, 2013   View Article

The Internet may soon reach into the depths of the world’s oceans and relay real-time information to smartphones everywhere — about everything from drug-smuggling submarines and the location of untapped oil reserves to the approach of a deadly tsunami.

Arrays of scientific instruments already bob on ocean buoys, hitch rides on sea turtles and lay bolted to seafloors. But they communicate with each other and scientists in myriad and often inefficient ways, explained Tommaso Melodia, an electrical engineer at the University of Buffalo in New York who is leading the development of the deep-sea Internet.

$2 million in prizes offered for better tools to monitor ocean acidification

Publication: NBC News   Date: September 9, 2013   View Article

The tools that scientists use to monitor the acidification of the world’s oceans are expected to get a major upgrade, thanks to a $2 million competition aimed at rewarding innovations that lower the cost and improve the accuracy of chemical sensors.

The Wendy Schmidt Ocean Health X Prize, unveiled Monday, is the latest multimillion-dollar prize program conducted by the California-based X Prize Foundation. Past prizes have targeted technologies ranging from commercial spaceflight to energy efficient cars— but the latest prize focuses on an even bigger global issue: climate change.
