Ocean Gliders: The New Storm Chasers

Unmanned ocean gliders go deep to help improve hurricane forecastsA fleet of 15 autonomous underwater vehicles (AUV), or gliders, will be deployed to collect important ocean data in the Caribbean Sea and tropical Atlantic Ocean that could prove useful to forecasters this hurricane season.NOAA, the U.S. Integrated Ocean Observing System and university partners will begin deploying the torpedo-shaped, remotely-operated, battery-powered gliders from vessels off Puerto Rico and the U.S. Virgin Islands in mid-July. Ten of the gliders will come from the U.S. Navy, and the others from NOAA.The gliders will

Drifting Iceberg Puts Greenland on High Alert

An iceberg the size of a hill has drifted close to a tiny village on the western coast of Greenland, causing fear that it could swamp the settlement with a tsunami if it calves.The iceberg towers over houses on a promontory in the village of Innaarsuit but it is grounded and has not moved overnight, state broadcaster KNR reported.A danger zone close to the coast has been evacuated and people have been moved further up a steep slope where the settlement lies, a Greenland police spokesman told Reuters.“We can feel the concern among the residents. We are used to big icebergs, but we haven’t

German North Sea Wind Production on the Rise

Offshore wind power plants in Germany's North Sea produced 5.15 percent more electricity from January to June than in the same period in 2017 at 8.17 terawatt hours (TWh), TenneT, the grid operator for the region, said on Thursday.On the day of highest capacity use, TenneT said 4,431 megawatts (MW) were tapped. This is equivalent to four to five big nuclear plants, or 44.4 percent of Germany's existing nuclear reactor total.North Sea wind accounted for 15.1 percent of total German wind production in that period, although that is not a fixed number because it depends on weather patterns.If a

The iMARL is a network of deep sea ocean sensors including ocean bottom seismographs (OBS), broadband acoustic sensors, and RBRquartz³ BPRs for measuring absolute water pressure and temperature at the ocean floor. Strapped to deep sea landers, the iMARL network will allow for the detection of offshore earthquakes and offshore storms, as well as noise in the ocean and biologically generated acoustic signals.The RBRquartz³ BPR uses an integrated Paroscientific Digiquartz pressure sensor to ensure initial accuracy, resolution and low drift performance.

Ocean Robots Gather Live Data from Volcano Lava Flow

Two high-tech autonomous ocean robots have been deployed to capture live ocean data close to where lava is flowing into the ocean from Hawaii’s Kilauea Volcano.By using Liquid Robotics’ unmanned Wave Gliders, scientists have the rare opportunity to study the effects of the lava entering the ocean, the plume it creates and the interactions of the lava and seawater directly from the surface of the ocean. Scientists note that very few volcanic eruptions and lava flows have ever been monitored in real time from the ocean.Over a three-week mission, the long-duration wave and solar powered Wave

How Does River Outflow Impact Coastal Sea Level?

A new study led by the Woods Hole Oceanographic Institution (WHOI) has uncovered a new factor affecting coastal sea levels.Tides, winds, waves and even barometric pressure have been known to play a role in the ebb and flow of the ocean in coastal areas. According to the recent study, river outflow could play a role in sea level change as well.The study, published July 9 in the journal Proceedings of the National Academy of Sciences, examined decades’ worth of river level and tidal data from gauges installed throughout the eastern U.S. The researchers then combined that data with information on

Subsea Robotics for Renewables

As the global fleet of offshore renewables fleet increases, ways to reduce the cost and increase the efficiency and safety of operations and maintenance work, using robotics and autonomous systems, will also grow. Elaine Maslin reports.Robotics and autonomous systems are moving into many areas of modern day life. It’s becoming harder to avoid them, from our phones to automotive systems and now offshore energy renewable projects.Both are seen as tools to do otherwise dull, dirty or dangerous work, without human involvement, but also as a way to reduce operational cost and to produce more reliable
