Natural reefs are being decimated by mankind and artificial reefs are becoming a viable alternative. (PRWEB) October 05, 2013 Reefs are a wellspring
The continued accumulation of sand within the iconic ring-shaped reefs inside Maldivian atolls could provide a foundation for future island development new research suggests.
A new research paper shows that a great number of nearby terrigenous pollen and charcoal have been found from the deep-sea sediments of the last 200 kyrs in Okinawa Trough.
New research indicates that crustacean populations living near rapidly declining coral reef habitats could be at risk.
New research has revealed that more ice leaves Antarctica by melting from the underside of submerged ice shelves than was previously thought, accounting for as much as 90 per cent of ice loss in some areas.
One tornado can be damaging enough; severe weather systems that spawn hundreds of deadly tornadoes in super-outbreaks pose special challenges to the scientific and emergency management communities.
Based on satellite data, experts have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event.
Deep ocean waves play a vital role in long-term climate cycles and a new study from scientists at the University of Washington has revealed waves the height of skyscrapers circulating energy and nutrients deep below the Southern Pacific Ocean.
A research team led by professors at the University of California Santa Barbara (UCSB) has revealed that, contrary to popular belief, an ice sheet on West Antarctica existed 20 million years earlier than previously thought.
Major weather events can shock an ecosystem, but they are also part of Earth’s natural cycle, and many species are adept at recovering from an environmental shake up.
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...
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...
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...
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...
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...
