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....

A drifting buoy is deployed.
2012-01-28 13:36:26

The tsunami that followed on the heels of the March 11, 2011, earthquake in Japan produced as much as 25 million tons of debris. Much of this debris was swept into the ocean. What stayed afloat drifted apart under the influence of winds and currents, most of it eastward. Predicted to reach the West Coast of the United States and Hawaii within the coming years, the debris' composition and how much is still floating on the surface are largely unknown. One thing is certain: the debris is...

North Atlantic “Blocking” Will End the Very Mild, Early Winter and May Usher in Much Cooler Weather Andover, MA (PRWEB) January 23, 2012 WSI (Weather Services International) expects temperatures for the upcoming period (February-April) to average lower than normal across the UK, along with parts of western Europe and Norway, with above-normal temperatures common elsewhere, most notably, across southeastern Europe. “The first half of winter has clearly been much milder...

Repeating La Niña Hitting Its Peak: NASA
2012-01-21 04:27:40

La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean shown above. The image is based on the average of...

Image 1 - Increased Ice Loss Resulted In Greater Greenland Bedrock Lifting
2011-12-11 06:42:42

A higher-than-normal 2010 melting season sped up the melting of ice in southern Greenland, causing sizable portions of the island's bedrock to rise somewhere about a quarter of an inch more than usual, an Ohio State University (OSU) researcher said on Friday. According to an OSU press release, Michael Bevis, Ohio Eminent Scholar in Geodynamics and professor in the OSU School of Earth Sciences, said that 50 GPS stations spread across the coast of Greenland normally "detect uplift of 15 mm...

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...
