Forecasting Winter Weather Using Airflow
2013-05-15 18:41:51

Lee Rannals for redOrbit.com — Your Universe Online Researchers writing in the Royal Meteorological Society publication Weather said forecasting winter weather over Europe has become more difficult over the years. A team at the National Oceanography Center uncovered the relationship between winter weather and the strength of the airflow coming in from the Atlantic, saying it is stronger in some years than others. This airflow is one of the factors used by meteorologists to...

New Study On Coral Reef Formations Lays To Rest Conflicting Theories
2013-05-14 07:53:01

April Flowers for redOrbit.com - Your Universe Online In the South Pacific, three types of coral reef island formations have fascinated geologists for ages. The coral of Tahiti forms a “fringing” reef, with a shelf growing close to the island´s shore. In Bora Bora, the “barrier” reefs are separated from the main island by a calm lagoon. Manuae represents the last type, an “atoll,” which appears as a ring of coral enclosing a lagoon with no island at...

Iceberg Production Modeled For Greenland Glaciers
2013-05-09 05:59:32

April Flowers for redOrbit.com - Your Universe Online Climate change impacts on the surface of the Greenland Ice Sheet have been widely studied. An understanding, however, of the key processes in iceberg production has eluded researchers for a long time. A new study, led by the Universite Libre de Bruxelles, presents a sophisticated computer model that provides fresh insight into the impact of climate change on the production of icebergs by Greenland glaciers. The model also demonstrates...

Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

Brett Smith for redOrbit.com - Your Universe Online When corals become stressed, they expel their symbiotic algae companions in a process known as “bleaching.” Corals can survive the bleaching, but it leaves them highly vulnerable and often results in die-off. As a changing climate threatens to bleach the corals of the world´s oceans on a massive scale, a team of researchers from Northwestern University has found that some corals facilitate bleaching through the...

Strong Correlation Between Asian Summer Monsoon And The Climate Pattern That Preceded It
2013-04-24 10:13:28

University of California, San Diego For much of Asia, the pace of life is tuned to rhythms of monsoons. The summer rainy season is especially important for securing the water and food supplies for more than a billion people. Its variations can mean the difference between drought and flood. Now a Scripps Institution of Oceanography, UC San Diego-led study reports on a crucial connection that could drastically improve the ability of forecasters to reliably predict the monsoon a few months...

In 2009, the North Carolina Coastal Resources Commission (CRC), a body that controls and regulates coastal development in North Carolina, asked 13 members of its advisory Science Panel to prepare a report on the state of sea-level rise in North Carolina. After the report was published, there was a subsequent maelstrom regarding its utility and validity. In this month's issue of EARTH Magazine, Orrin Pilkey and Alexander Glass from Duke University describe what happened. Based on the...

Deep Magma Imaged Beneath Pacific Seafloor Volcano
2013-03-28 04:51:18

redOrbit Staff & Wire Reports - Your Universe Online By using electromagnetic technology to map a large area of seafloor near Central America and the northern East Pacific Rise, researchers from the Scripps Institution of Oceanography report that they have a better idea of the origin of the erupted magma that eventually becomes new seafloor. Scientists have known for several decades that the seafloor is formed throughout the major ocean basins at the linear chains of volcanoes known...

Greenland's Peripheral Glaciers Also Contribute Significantly To Sea-Level Rise
2013-03-18 13:39:33

Alan McStravick for redOrbit.com - Your Universe Online The oft-cliché idea behind the naming of Iceland and Greenland claims their names were derived in an attempt to fool would be sailing marauders, attracting them to the desolate but more hospitably named Greenland, leaving the citizens of Iceland to live upon their slightly more lush island without threat of invasion. In fact, Erik the Red, it is believed, gave the moniker to attract settlers to the ice covered island...

Significant Iron Contributed To North Atlantic Ocean By Glaciers
2013-03-11 12:23:52

Woods Hole Oceanographic Institution All living organisms rely on iron as an essential nutrient. In the ocean, iron´s abundance or scarcity means all the difference as it fuels the growth of plankton, the base of the ocean´s food web. A new study by biogeochemists and glaciologists at Woods Hole Oceanographic Institution (WHOI) identifies an unexpectedly large source of iron to the North Atlantic — meltwater from glaciers and ice sheets, which may stimulate plankton...

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...
