Natural reefs are being decimated by mankind and artificial reefs are becoming a viable alternative. (PRWEB) October 05, 2013 Reefs are a wellspring of strange and beautiful sea-life, catering to an entire ecosystem and acting as an important shelter for multiple protected species. Many of these plants and animals exist only within or around these reefs, and are being destroyed by reckless seafaring and pollution. Artificial reefs, designed and implemented by man, may help to curb the...

New Island Formation In The Maldives Should Not Be Restricted By Future Sea Level Rise
2013-09-26 12:23:48

University of Exeter 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. Islands like the Maldives are considered likely to be the first to feel the effects of climate change induced sea level rise, with future island growth essential to counter the threat of rising sea levels. The study published in the journal Geology, and carried out by researchers from the...

Coral Decline Affects Crustacean Biodiversity
2013-09-23 15:48:53

Brett Smith for redOrbit.com - Your Universe Online With many scientists expecting climate change to have a devastating effect on the world’s coral reefs over the coming century, new research from the University of Florida indicates that crustacean populations living near rapidly declining reef habitats could be at risk. Appearing in the November issue of the journal Geology, the new study is based on an analysis of the fossil record surrounding decapod crustaceans, a group that...

Widespread Contamination Caused By Mine Metals At Maine Superfund Site
2013-09-20 09:29:35

Dartmouth College Dartmouth study is among first to analyze open pit mining's impact on US estuaries, coastal food web Toxic metals from the only open pit mine in an estuary system in the United States are widespread in nearby sediment, water and fish and may be affecting marine and coastal animals that feed on them beyond the mine site, a new Dartmouth study finds. Mining contamination's effects on human health and aquatic and terrestrial wildlife is well documented in the United...

Skyscraper-Size Waves Circulate Energy, Nutrients In Deep Ocean
2013-09-09 15:51:47

Brett Smith for redOrbit.com - Your Universe Online While massive waves are a surfer’s dream, they are also fascinating to oceanographers – particularly those waves breaking deep in the ocean. These 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. “Climate models are really sensitive...

Shocking Reefs Back To Life
2013-09-02 10:56:39

Brett Smith for redOrbit.com - Your Universe Online 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. New research from a joint team of Australian and Swedish researchers has shown that ecosystem shocks caused by changing climate or seasons could play a key role in bringing back some of the world’s badly degraded coral reefs, according to a new report in the journal...

Rising Sea Waters Threaten Hawaiian Shorelines
2013-08-31 08:19:16

April Flowers for redOrbit.com - Your Universe Online In Hawaii, sea-level rise (SLR) has been isolated as a principal cause of coastal erosion. After examining other influences on shoreline change including waves, sediment supply and littoral processes, and anthropogenic changes, the best explanation for the difference in island-wide shoreline trends, such as beach erosion or accretion, is the differing rates of relative sea-level rise on the islands of Oahu and Maui. A new study,...

Epic Ocean-spanning Voyages Of Coral Larvae Revealed
2013-08-20 15:44:55

University of Miami Rosenstiel School of Marine & Atmospheric Science Models provide first-ever simulated glimpse into dispersal and potential effects of climate change A new computer simulation conducted at the University of Bristol (UB) and University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science has revealed the epic, ocean-spanning journeys traveled by millimeter-sized coral larvae through the world's seas. The study, published in Global Ecology and...

Coral Reef Biodiversity More Important To Divers Than Fish Abundance

[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...

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...

Mudflats
2013-04-19 21:07:34

Mudflats, or otherwise known as tidal flats, are coastal wetlands that form when mud is left behind by tides or rivers. They’re found in sheltered regions such as bayous, lagoons, estuaries, and bays. Mudflats might be seen geologically as exposed layers of bay mud, a result from the deposition of estuarine silts, marine animal detritus, and clays. The majority of the sediment in a mudflat is within the intertidal zone, therefore the flat is submerged and exposed about twice per day. In...

Salt Marsh
2013-04-19 21:04:15

A salt marsh, also otherwise known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone that lies between the land and the open salt water or brackish water that is routinely flooded by the tides. It’s dominated by dense stands of salt-tolerant plants, for example, herbs, grasses, or low shrubs. These plants originate from all around the globe and are important to the stability of the salt marsh in trapping and binding sediments. Salt marshes...

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...
