All About El Nino - A
2012-04-09 05:12:08

RedOrbit.com Meteorologist Joshua Kelly El Nino is a term used to describe a weather pattern that sets up in the Tropical Pacific Ocean. So you may ask why does it matter to me and should it matter to me? The answer is yes because it impacts each and every one of us on Earth. The impacts are felt from weather pattern changes to lifestyle changes. As we know, off the coast of Peru normally they will have cold upwelling waters that are found off the coast. This is important because it...

Are Ocean Levels And Temperatures On The Rise?
2012-04-02 13:29:53

A new study has revealed a global warming and rising of the oceans. Contrasting ocean temperature readings from the 1870s with modern readings, this study reveals an upward rising trend spanning over 100 years. Dan Roemmich, a Scripps Institution of Oceanography at UC San Diego physical oceanographer led the research. He found a .33 degree Celsius (.59-degree Fahrenheit) increase on average in the top portions of the ocean, down to 700 meters. Ocean surface temperatures, however, saw the...

Image 1 - West Antarctic Ice Shelves Tearing Apart at the Seams
2012-03-28 04:31:05

[ Watch the Video ] A new study examining nearly 40 years of satellite imagery has revealed that the floating ice shelves of a critical portion of West Antarctica are steadily losing their grip on adjacent bay walls, potentially amplifying an already accelerating loss of ice to the sea. The most extensive record yet of the evolution of the floating ice shelves in the eastern Amundsen Sea Embayment in West Antarctica shows that their margins, where they grip onto rocky bay walls or...

Image 1 - Scientists Examine Peculiar Underwater Mountain
2012-03-27 10:53:47

Scientists have recently finalized an expedition in an effort to learn more about an undersea mountain they say may have formed in a very different way than the rest of the seafloor. Aboard the JOIDES (Joint Oceanographic Institutions for Deep Earth Sampling) research ship, these scientists studied the formations and makeup of Atlantis Massif. This undersea mountain has been found to be made up of rocks typically found much deeper in the oceans crust. Other volcanic seamounts are usually...

Fishing Boat Missing Since 2011 Tsunami Found
2012-03-25 05:31:36

A large Japanese fishing trawler that was swept away by the devastating tsunami of 2011 has been spotted off the coast of British Columbia in the western part of Canada, various media outlets reported Saturday. According to the Associated Press (AP), the 50-foot long vessel had been discovered approximately 160 miles west of Haida Gwaii, where it had been slowly drifting towards the shore. Officials had identified it as originating from Hokkaido, Japan, and rescue workers said that...

Rising Sea Levels Could Boost Storm Surges
2012-03-16 05:19:24

Sea level rise due to global warming has already doubled the annual risk of coastal flooding of historic proportions across widespread areas of the United States, according to a new report from Climate Central. By 2030, many locations are likely to see storm surges combining with sea level rise to raise waters at least 4 feet above the local high-tide line. Nearly 5 million U.S. residents live in 2.6 million homes on land below this level. More than 6 million people live on land below 5 feet;...

Marking The One-Year Anniversary Of The Japanese Earthquake And Tsunami
2012-03-10 06:14:43

World leaders, scientists, and members of the media are among those pausing this weekend to reflect on the one-year anniversary of the 9.0 magnitude earthquake that struck Japan on March 11, 2011 and, combined with the ensuing tsunami, caused widespread death and destruction throughout the country. "As we mark one year since the catastrophic earthquake, tsunami and nuclear disasters in Japan, Michelle and I join all Americans in honoring the memory of the 19,000 victims lost or missing,"...

Did The Moon Play A Role In Sinking The Titanic?
2012-03-06 12:27:19

A team of astronomers from Texas State University is claiming the moon was an accomplice in bringing down the Titanic. Texas State researcher Donald Olson said the moon may help explain why the icebergs initially got into the path of the Titanic. “Of course, the ultimate cause of the accident was that the ship struck an iceberg. The Titanic failed to slow down, even after having received several wireless messages warning of ice ahead,” Olson said recently. The researchers...

Scientists Search For Causes Of 2010 'Snowmaggedon'
2012-02-10 04:32:18

[ Watch the Video ] In the quiet after the storms, streets and cars had all but disappeared under piles of snow. The U.S. Postal Service suspended service for the first time in 30 years. Snow plows struggled to push the evidence off of major roads. Hundreds of thousands of Washington metropolitan residents grappled with the loss of electricity and heat for almost a week. By Feb. 10, 2010 the National Weather Service reported that three storms spanning from December to February in the...

Researchers Taking Stock Of Earth's Melting Ice
2012-02-09 10:36:22

[ Watch the Video ] In a new study led by researchers at the University of Colorado at Boulder, scientists using NASA data have found that Earth´s glaciers and ice caps outside of the regions of Greenland and Antarctica are losing nearly 150 billion tons of ice annually. Using satellite measurements from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE), researchers were able to measure ice loss in all of Earth´s land ice between 2003 and 2010....

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...

Climate Impact On Your Budget For Bismarck, North Dakota
2012-09-18 13:29:03

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...
