Thermometer-equipped cod provide valuable data

By - February 25, 2011 2 Pictures
With the advent of robust, miniaturized electronic devices, an increasingly common method of studying wild animals involves temporarily attaching data-logging sensors directly to them. Some readers might have seen point-of-view video footage obtained with National Geographic's "Crittercam," for instance, or heard about the study where the migratory routes of Arctic terns were determined by putting tiny light loggers on the birds. Now, a consortium of scientists from nine European research institutions have tagged cod fish with mini-thermometers, to find out how they will be able to cope with rising ocean temperatures.

Oasis at sea: The Ark hotel concept

By - December 30, 2010 17 Pictures
Russian architectural firm Remistudio has taken the concept of a man-made biosphere and gone to sea with its vision for the floating "Ark Hotel." Designed to withstand floods, tidal waves and rising ocean levels as well as earthquakes and other natural disasters, the hotel concept would float and function independently on the surface of a body of water, providing a green, self-sustaining environment for guests who presumably, would never have to leave.

IMOS monitors almost one-third of the world's oceans

By - December 22, 2010 7 Pictures
Australian climate and ocean scientists are studying some of the planet's most remote areas using a multi-million dollar array of high-tech underwater equipment that provides data vital for the monitoring of almost one-third of the world's oceans. The kit of technology includes sensor floats and autonomous underwater vehicles, which combine with sensor tagged animals, moored scientific stations and satellite remote sensing to form the Integrated Marine Observing System (IMOS). All data collected is made available online, which represents a big step forward in climate science. Gizmag's Grant Banks takes a closer look at what makes IMOS tick. Read More

ScanEagle UAV and image recognition software used to track seals

By - December 18, 2010 2 Pictures
The Arctic region is currently experiencing a warming trend which is seeing the ice cap break apart, and may even ultimately result in the total absence of ice in the summer months. Many scientists attribute this trend to man made global warming, but whatever the cause, it’s not good news for the seals that breed, rest, and escape marine predators on the ice. In an effort to understand the full scope of the situation, scientists have turned to the Boeing-designed Scan Eagle – an unmanned aerial vehicle more often used for military reconnaissance.

Eggshells could be used to fight global warming

By - October 29, 2010 1 Picture
Carbon capture and sequestration (CCS) is a hot area of research in the effort to fight global warming through the process of removing carbon from the atmosphere and ferreting it away within carbon soaking materials, a team from the University of Calcutta has found an unexpected (or should that be uneggspected) material that could trap carbon from the atmosphere in the form of eggshells. The team has demonstrated that the membrane that lines an eggshell can absorb almost seven times its own weight of carbon dioxide from the atmosphere, allowing the gas to be stored until environmentally friendly methods of disposing, or even using it, can be found.

Wind farms can cause change in local temperatures

By - October 5, 2010 1 Picture
The benefits of wind farms in terms of global climate change are well recognized but according to researchers at the University of Illinois they can also affect local climates as well. The researchers observed that the area immediately surrounding a wind farm is slightly warmer at night and slightly cooler during the day compared to the rest of the region. The discovery could allow for strategies to mitigate those effects in areas where they are undesirable, or take advantage of them in others. Read More

Ozone layer no longer decreasing

By - September 19, 2010 1 Picture
A new report suggests that international efforts to halt the destruction of the ozone layer have been successful. Launched on the UN International Day for Preservation of the Ozone Layer, the report by 300 scientists also provides new information about the net effects on Earth's climate, and also the effects of climate change on the ozone later moving forward.

'Dry water' could be used to store carbon dioxide

By - August 25, 2010 1 Picture
You know, I’m pretty sure I remember a Far Side cartoon or something, where someone was selling powdered water – “Just add water!” Well, dry water isn’t quite the same thing. It’s 95 percent liquid water, but that water takes the form of tiny droplets each encased in a tiny globe of silica. The resultant substance is dry and granular. It first came to light in 1968, and was used in cosmetics. More recently, a University of Liverpool research team has been looking into other potential uses for the substance. They have found several, but most interesting is its ability to store gases such as carbon dioxide. Read More

First solar/coal hybrid power station up and running

By - July 15, 2010 2 Pictures
The world's first hybrid solar/coal power plant has been built near Palisade in Colorado. Xcel Energy and Abengoa Solar are partnering on the demonstration project which uses solar parabolic trough technology to supplement the use of coal. Initially, it's expected to reduce the emissions generated by the Cameo Station's Unit 2 plant by three to five percent, but it's thought that this could increase to up to ten percent. Read More
