New research by the Lawrence Livermore National Laboratory suggests global ocean warming has been underestimated by 24 to 58 percent. The research appears in the October 5 issue of the journal Nature Climate Change. Livermore, California (PRWEB) October 07, 2014 Using satellite observations and a large suite of climate models, Lawrence Livermore scientists have found that long-term ocean warming in the upper 700 meters of Southern Hemisphere oceans has likely been underestimated....

Pacific Ocean

Brett Smith for redOrbit.com - Your Universe Online Water expands as it gets warmer and climatologists have suspected that warming in the deep ocean may add to rising sea levels around the world. However, a new study has found evidence that the deep ocean is not warming measurably. The study researchers, from at NASA's Jet Propulsion Laboratory (JPL) in California, added that this finding, reported in the journal Nature Climate Change, does not solve the mystery of why global warming...

WASHINGTON, Oct. 6, 2014 /PRNewswire-USNewswire/ -- The cold waters of Earth's deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24...

ARC Centre of Excellence for Climate System Science Current changes in the ocean around Antarctica are disturbingly close to conditions 14,000 years ago that new research shows may have led to the rapid melting of Antarctic ice and an abrupt 3-4 meter rise in global sea level. The research published in Nature Communications found that in the past, when ocean temperatures around Antarctica became more layered - with a warm layer of water below a cold surface layer - ice sheets and...

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers has developed a new, vivid map illustrating the world’s seafloor with twice the detail and accuracy of the previous version, which was created over 20 years ago. Using two streams of previously untapped data, scientists have mapped thousands of previously uncharted mountains rising from the seafloor along with providing additional clues about the formation of the continents. According to a study...

The Unpredictable El Niño Of 2014
2014-09-24 03:32:30

Alan Buis, NASA's Jet Propulsion Laboratory Prospects have been fading for an El Niño event in 2014, but now there's a glimmer of hope for a very modest comeback. Scientists warn that unless these developing weak-to-modest El Niño conditions strengthen, the drought-stricken American West shouldn't expect any relief. The latest sea-level-height data from the NASA/European Ocean Surface Topography Mission (OSTM)/Jason-2 satellite mission show a pair of eastward-moving waves of higher...

Great Barrier Reef Is An Effective Wave Absorber: Study
2014-09-19 03:25:13

University of Southampton New research has found that the Great Barrier Reef, as a whole, is a remarkably effective wave absorber, despite large gaps between the reefs. This means that landward of the reefs, waves are mostly related to local winds rather than offshore wave conditions. As waves break and reduce in height over reefs, this drives currents that are very important for the transport of nutrients and larvae. This reduction in wave height also has implications for shoreline...

“The Tsunami That Reshaped America” by James W. Mercer portrays new risks in the U.S. GREAT FALLS, Va. (PRWEB) September 09, 2014 Science can no longer be ignored. In his new novel “The Tsunami That Reshaped America,” author James W. Mercer, a hydrogeologist, provides a scientific-based political thriller following a fictitious plot to overthrow the U.S. government using geological warfare. “Natural threats triggered by humans have the potential to destroy large segments of the...

Coral Reef
2013-04-20 15:49:21

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Current Sea Level Rise
2013-04-01 10:39:21

The sea levels all around the world are rising. Current sea-level rise has the potential to affect human populations and the natural environment. Two key factors have contributed to the observed sea level rise. The first is thermal expansion: as the ocean water warms, it expands. The second is from the influence of land-based ice because of increased melting. The major store of water on land is found in the glaciers and the ice sheets. The rising of sea levels is one of several lines of...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...

Climate Impact On Your Budget For Billings Montana
2012-12-29 12:40:14

If you live in or around Billings, Montana the above graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. In Billings during a normal phase of the ENSO your heating degree days pass 900HDD. However, when El-Nino phase is present the monthly average dropped to around 650.5HDD, which is a pretty significant amount especially when you are talking about paying that heating bill. When the La-Nina phase sets up the heating degree...

If you live in or around Bismarck North Dakota the graph shows you what you can roughly expect when it comes to heating and cooling your house during the ENSO Phases. Bismarck North Dakota, with its northern latitude, does have an impact on what type of heating and cooling it sees. During an Normal Phase the HDD for the region hits about 1348 on average. When the region enters into an El-Nino they can expect the amount of HDD’s to decrease to around 970 which really helps cut down on the...
