Acoustic Wave Tsunami Warning System
2013-08-29 13:34:12

[ Watch the Video: What is a Tsunami? ] Peter Suciu for redOrbit.com – Your Universe Online While the waves from a tsunami can be extremely destructive, acoustic waves could help warn of the impending danger. Not much can be done to actually stop these natural disasters, but the earlier a warning goes out that a tsunami could strike the coast, the better the chances of effectively evacuating the area. Early warning systems play a critical role in ensuring that people reach safety,...

Coral Reef Biodiversity More Important To Divers Than Fish Abundance
2013-08-20 15:31:55

[WATCH VIDEO: Tamar Artificial Reef Now Teeming With Life] Brett Smith for redOrbit.com - Your Universe Online With ecotourism on the rise, determining what elements of a nature-based attraction are most appealing can have significant consequences financially and for raising awareness of conservation issues. In a new study of the Negev from Ben-Gurion University (BGU) in Israel, researchers found that divers were able to differentiate between an artificial reef’s biodiversity and...

When enough raindrops fall over land instead of the ocean, they begin to add up. New research led by the National Center for Atmospheric Research (NCAR) shows that when three atmospheric patterns came together over the Indian and Pacific oceans, they drove so much precipitation over Australia in 2010 and 2011 that the world’s ocean levels dropped measurably. Unlike other continents, the soils and topography of Australia prevent almost all of its precipitation from running off into the...

Smallest Continent Had Biggest Role In Sea Level Drop
2013-08-20 08:53:03

NASA A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time, finds a new study co-authored and co-funded by NASA. In 2011, scientists at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., and the University of Colorado at Boulder reported that between early 2010 and summer 2011, global sea level fell sharply, by about a...

Unexpected Plume Challenges Iron Estimates
2013-08-20 08:47:27

April Flowers for redOrbit.com - Your Universe Online A vast plume of iron and other micronutrients more than 620 miles long has been discovered billowing from hydrothermal vents in the South Atlantic Ocean. Teams of scientists from Woods Hole Oceanographic Institute (WHOI) and the University of Liverpool, UK say their findings, published in an upcoming issue of Nature Geoscience, call into question past estimates of iron abundances and may challenge researchers’ previous assumptions...

Glacial Melt Minimal Effect On Sea Level
2013-08-13 09:47:09

Brett Smith for redOrbit.com - Your Universe Online Occasionally, melt water on top of a glacier will trickle down to the bedrock below and act as a lubricant for the glacier’s movements. Once thought to be a major contributor to sea-level rise, melt water was found to have only a minor effect on sea level in a new study from a team of European and American scientists. Using computer modeling based on observations of Greenland’s ice sheet, the research team concluded glacier...

Coastal American Cities Threatened By Sea-Level Rise
2013-07-31 08:55:40

Michael Harper for redOrbit.com - Your Universe Online Boston, Miami, New York and more than 1,700 other coastal American cities are facing a greater risk from rising sea levels than had previously been estimated. A new study published in the Proceedings of the National Academy of Sciences (PNAS) claims at least 316 American cities will one day be overtaken by the sea if pollution continues to grow as it has been. More than 1,400 other cities will be "locked-in" by rising sea...

How Cold, Deep Ocean Waters Influence Sea Surface Temperatures
2013-07-26 06:04:28

Brett Smith for redOrbit.com - Your Universe Online Newly published research from Oregon State University has revealed new details on the forces behind El Nino and could lead to more refined predictions for global warming. According to their report in the journal Nature, OSU scientists have used new measurements of ocean mixing to record the first multi-year data set that will allow for a comprehensive analysis of how cold, deep ocean waters can influence sea surface temperatures on a...

Pipeline Wave Frozen In Time
2013-07-23 05:40:15

April Flowers for redOrbit.com - Your Universe Online A team of scientists from the Universidad Carlos III of Madrid (UC3M) and the University of California - San Diego (UC San Diego) have created a static pipeline wave in a laboratory. The wave has a crest that moves neither forward nor backward, which will allow improvements in boat and seaport designs. The wave will also allow analysis of how carbon dioxide exchange between the ocean and the atmosphere occurs. The study findings are...

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...
