National Weather Service alerts headed to smartphones

Live in an area prone to flash floods, hurricanes, blizzards? Smartphone users will soon get a severe-weather alert from the National Weather Service, a division of the National Oceanic and Atmospheric Administration.

The new nationwide emergency alert system, called the Wireless Emergency Alerts (WEA), sends 90-character text messages to smartphones of people facing extreme weather conditions. Severe weather defined by the NOAA includes tornadoes, flash floods, hurricanes, extreme wind, blizzards and ice storms, tsunamis, and dust storms. Note that thunderstorms aren't on the list because they occur so frequently. … Read more

Will Cameron's deep-sea voyage yield breakthrough drugs?

Blockbuster-moviemaker-turned-aquanaut James Cameron's solo dive in the Pacific to the Mariana Trench's Challenger Deep site last month opens up a vast, under-explored region of the world's oceans to researchers. There, scientists hope to discover, retrieve, and study a host of previously unknown organisms and chemical compounds that may someday help solve decades-old medical mysteries.

"What better place to look for adaptations and unusual compounds that have unusual characteristics than in the most extreme environments we can go to on this planet," says Richard Lutz, a professor of marine ecology and biology of deep-sea hydrothermal vents … Read more

NASA video visualizes a 'Perpetual Ocean'

NASA has released a computer visualization project called "Perpetual Ocean" that presents a data-created time lapse of the Earth's ocean and sea surface currents over a two-year period.

The animation (see below) shows the globe slowly spinning as white swirls curl and move in the water around landmasses. It looks as if Vincent van Gogh had painted into the oceans -- from the Gulf of Mexico to the Indian Ocean to the Black Sea.

Using NASA's Jet Propulsion Laboratory's computational model called Estimating the Circulation and Climate of the Ocean Phase II ( ECCO2), scientists simulated … Read more

Cameron and Branson race to bring urgent attention to oceans

Did famed filmmaker James Cameron just do for the oceans what scientific experts have struggled to do for decades?

When "Avatar" and "Titanic" director Cameron piloted his custom submersible, the Deepsea Challenger, to the bottom of the Mariana Trench yesterday and became the first person ever to make a solo dive to the world's deepest spot, he shined a crucial spotlight on the field of ocean exploration.

In recent years, scientists have been shouting from rooftops around the world that unless humanity puts more energy into studying our oceans, we are at real risk of … Read more

Oceans are acidifying faster than ever

The burning of fossil fuels and the release of carbon dioxide into the atmosphere don't affect just the air--it also impacts the Earth's oceans, according to U.S. National Oceanic and Atmospheric Administration (NOAA).

Oceans absorb the carbon dioxide, which in turn changes the water's pH acidity levels. What this means is that coral reefs are growing at a slower rate and the survival of marine species is decreasing, according to NOAA.

Now, the speed at which ocean pH level is changing is faster than any time in the last 300 million years, according to a new … Read more

Google launches underwater endeavor with Seaview

Imagine if Google Earth could take users under the ocean. People on laptops sitting hundreds of miles away from any body of water could dive down and spot colorful reef fish, coral forests, sea snakes, and rare turtles. A program just like this was officially announced today.

In a partnership with Google, the global insurance company Catlin Group Limited and nonprofit Underwater Earth launched the Catlin Seaview Survey. The goal is to let people explore the ocean from afar and also carry out the first detailed study about the composition and health of coral reefs. The mapping expedition is expected … Read more

'R2D2s of the sea' sails across Pacific for science

As you read this, four wave-propelled robots are making their way across the Pacific Ocean in a record-setting journey that will hopefully lead to new scientific discoveries. But they need your help.

With the support of Virgin Oceanic and Google Earth, Sunnyvale, Calif.-based company Liquid Robotics launched four of its Wave Glider ocean robots on November 17 to embark on a PacX (as in Pacific crossing) expedition, where they are expected to collect 2.25 million pieces of data about the ocean. The Wave Gliders feature a wing system that uses wave motion to propel the robots, while solar panels power the various sensors used to collect data. … Read more

Ocean-faring robots set sail on Guinness record attempt

SAN FRANCISCO--Four robots left the Golden Gate today on an across the globe mission to set a world distance record and demonstrate new data-gathering tools that could help save the planet.

The robots, known as Wave Gliders, were built by a Silicon Valley startup known as Liquid Robotics. And starting today, the four autonomous sea-faring craft are heading out on journeys to Australia and Japan with the intention of setting the Guinness World Record for the longest distance traveled on the surface of the Earth by a robot.

The four Wave Gliders are thought to be capable of traveling across … Read more

IBM listens in on wave energy's subsea sounds

Harnessing energy from the oceans involves a lot more than putting a generator in the water.

IBM Research today announced a project to monitor the impact of noise on marine ecosystems from a wave energy generator in Ireland. Done in conjunction with the Sustainable Energy Authority Ireland, its part of an ongoing SmartBay project to monitor the environment of Galway Bay with sensors and telemetry to advance ocean energy.

To monitor the acoustic impact of wave power, a generator from OceanEnergy in Ireland is equipped with audio sensors. Data from the sensors is fed continuously to IBM's data centers … Read more
