BRUSSELS, Oct. 11, 2012 /PRNewswire/ -- Environmental degradation is a significant factor that reduces the capacity of societies to deal with disaster risk in many countries around the world. This is the key message of the World Risk Report 2012, presented today in Brussels, Belgium by the German Alliance for Development Works (Alliance), United Nations University Institute for Environment and Human Security (UNU-EHS) and The Nature Conservancy. The report examines the risks of and...

Coral Hotspots Found In Deepwater Canyons
2012-09-28 04:33:26

Alan McStravick for redOrbit.com - Your Universe Online When most people think of coral reefs, they are transported to temperate waters in a tropical locale. To even locate a coral ecosystem in the cold waters of the mid and north Atlantic would be a difficult endeavor. Or, at least, one would have thought. A recent exploration of the continental shelf and slope of the Northeastern United States has revealed coral hotspots. These are areas that have an abundance of sea life existing in...

HOLLYWOOD, Fla., Sept. 12, 2012 /PRNewswire/ -- Nova Southeastern University will host a grand opening ceremony for America's largest coral reef research center on Sept. 27. Media Kit with video and photos: http://www.nova.edu/ocean/excellence/index.html NSU scientists are conducting reef research locally, nationally and globally at the 86,000-square-foot Center of Excellence for Coral Reef Ecosystems Research. The facility is located at NSU's Oceanographic Center at John U. Lloyd Beach...

A new model allows researchers at UNESCO-IHE, TU Delft and Deltares to much more accurately predict coastline erosion due to rising sea levels. It would appear that the effects of coastline erosion as a result of rising sea-level rise in the vicinity of inlets, such as river estuaries, have until now been dramatically underestimated. The scientists have published their research in the online edition of Nature Climate Change on Sunday 2 September. Coastline recession The anticipated rise...

New Model Used To Find Where Corals Are Most Likely To Survive Climate Change
2012-08-31 11:51:43

Marine conservationists from the Wildlife Conservation Society working with other coral reef experts have identified heat-tolerant coral species living in locations with continuous background temperature variability as those having the best chance of surviving climate change, according to a new simplified method for measuring coral reef resilience. Therefore, coral reefs with these characteristics should receive immediate attention for conserving this highly threatened ecosystem, according...

Coral Reef Diversity - Sometimes Less Is More
2012-08-29 10:08:25

Brett Smith for redOrbit.com - Your Universe Online A general rule of Darwinian evolution is that diversity provides for a more robust population that is capable of withstanding a higher degree of stress than a more homogenous population. However, researchers at the University of Hawaii at Manoa (UHM) have found that less diverse coral populations lead to reefs that are less sensitive to environmental disturbances, according to their report in Proceedings of the Royal Society B....

Charles Darwin Was Right - Some Species Can't Make The Trip
2012-08-28 11:07:18

April Flowers for redOrbit.com - Your Universe Online In 1880 Charles Darwin hypothesized that most species could not disperse across the Eastern Pacific Barrier (EPB). A new study, led by Iliana Baums, assistant professor of biology at Penn State University, is the first comprehensive test of that hypothesis using coral. The study, to be published in Molecular Ecology, found that a coral species in abundance from Indonesia eastward to Fiji, Samoa and the Line Islands rarely crosses the...

Additions To Coral Reef Woes Are Microbes, Sponges And Worms
2012-08-07 13:46:12

Study by Wildlife Conservation Society and University of the Azores identifies additional risks to reefs stemming from pollution and heavy fishing Microbes, sponges, and worms–the side effects of pollution and heavy fishing–are adding insult to injury in Kenya's imperiled reef systems, according to a recent study by the Wildlife Conservation Society and the University of Azores. The authors of the study have found that pollution and overfishing on reef systems have an...

Deepwater Horizon Spill Exacerbated Existing Problems In Louisiana Marshes
2012-06-26 04:10:50

The BP Deepwater Horizon oil spill temporarily worsened existing manmade problems in Louisiana's salt marshes such as erosion, but there may be cause for optimism, according to a new study. A study appearing online Monday in the Proceedings of the National Academy of Sciences found the 2010 spill killed off salt marsh plants 15 to 30 feet from the shoreline and this plant die off resulted in a more-than-doubled rate of erosion along the marsh edge and subsequent permanent marsh habitat...

Understanding The Effects And Impacts Of Flooding In The South Of England
2012-06-15 11:32:42

Research from the University of Southampton has developed and applied a method for understanding the effects and impacts of coastal flooding, which could contribute to more effective flood forecasting, defense design and land use planning. By using observations from real coastal floods and numerical models, researchers simulated coastal floods within the Solent region of the South of England to approximate the consequences of synthetic flood events, using land and property as example...

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...
