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...

When Tsunamis Break All The Rules
2013-03-07 05:04:34

[ Watch the Video: Animation of a Tsunami Wave ] April Flowers for redOrbit.com - Your Universe Online An international collaboration has resulted in a new study showing that the earthquake zones off certain coasts, such as Japan and Java, make them especially vulnerable to tsunamis. These zones can produce a focusing point that creates massive and devastating tsunamis capable of breaking the rules by which scientists used to think tsunamis worked. Previously, scientists largely...

Wave Patterns In The Atmosphere Help Explain Weather Extremes
2013-02-26 11:51:00

April Flowers for redOrbit.com - Your Universe Online In recent years, the world has suffered from severe regional weather extremes such as the heat wave in the US in 2011, or the one in Russia in 2010 that coincided with the unprecedented Pakistan flood. There is one common physical cause behind these individual events, according to a new study from the Potsdam Institute for Climate Impact Research [PIK]. The findings of the study, published in Proceedings of the National Academy of...

Global Sea-Level Rise Could Occur Unevenly Across Globe
2013-02-19 15:43:16

Peter Suciu for redOrbit.com — Your Universe Online The fact sea levels could rise if the polar ice caps melt has been long established, but according to new research some regions could see greater increases than others. According to research published in the journal Geophysical Research Letters, sophisticated computer modeling of sea-level rise over the coming century suggests parts of the Pacific could see the highest rates of rise while some polar regions will actually...

Picky Eaters Keep Endangered Coral Reefs Clean
2013-02-14 06:19:23

[ Watch the Video: Picky Eater Fish Endanger Coral Reefs ] Peter Suciu for redOrbit.com — Your Universe Online Few pet owners would expect their dog or cat to clean up the house, and anyone who has ever camped in places such as Yellowstone Park knows that bears can visit and will leave a campsite in worse shape than they found it. Fish on the other hand could actually be doing some good in cleaning up coral reefs. A recent study conducted in the Fiji Islands found that four...

Rare Cold Volcanic Vent Discovered In Antarctic Waters
2013-02-07 10:51:55

April Flowers for redOrbit.com - Your Universe Online Scientists at the National Oceanography Centre (NOC), Southampton have discovered the location of an underwater volcanic vent in the Southern Ocean. In a study published this week in the journal PLOS ONE, the researchers describe how this vent, marked by a low-lying plume of shimmering water, differs from "classic" hydrothermal vents. The research group used the NOC´s high-resolution deep-towed camera platform SHRIMP to image...

Powerful 8.0 Magnitude Earthquake Strikes Solomon Islands, Triggers Deadly Tsunami
2013-02-06 07:00:15

Lee Rannals for redOrbit.com — Your Universe Online Villages on the Solomon Islands were struck by an 8.0 magnitude earthquake Wednesday, triggering a deadly tsunami that has taken the lives of at least six people, according to the latest estimates. Coastal Pacific communities as far away as Hawaii and Australia were also on high alert following the temblor yesterday afternoon. The Pacific Tsunami Warning Center (PTWC) said that a small tsunami wave reached part of the Solomon...

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...
