Fish Colonized Reefs In Two Distinct Waves

University of California, Davis The world's reefs are hotbeds of biological diversity, including over 4,500 species of fish. A new study shows that the ancestors of these fish colonized reefs in two distinct waves, before and after the mass...

University of Southampton A new publication from researchers at the University of Southampton and the National Oceanography Centre, Southampton highlights the importance of nutrients for coral reef survival. Despite the comparably small footprint they take on the ocean floor, tropical coral reefs are home to a substantial part of all marine life forms. Coral reefs also provide numerous benefits for human populations, providing food for millions and protecting coastal areas from erosion....

Climate Change Could Cause Trillions In Damage To World's Coastal Regions
2014-02-05 10:28:40

University of Southampton New research predicts that coastal regions may face massive increases in damages from storm surge flooding over the course of the 21st century. According to the study published in the Proceedings of the National Academy of Sciences, global average storm surge damages could increase from about $10-$40 billion per year today to up to $100,000 billion per year by the end of century, if no adaptation action is taken. The study, led by the Berlin-based think-tank...

First Ever Cold Water Coral Reef Found In Greenland
2014-01-28 13:46:36

[ Watch the Video: Cold Water Coral Reef Discovered In Greenland ] Lee Rannals for redOrbit.com - Your Universe Online Researchers have discovered the first ever cold-water coral reef in Greenland at a depth of nearly 3,000 feet below sea-level. Scientists have found several species of coral in Greenland, but this is the first time that an actual reef has been found. The team discovered the Greenlandic reef in southwest Greenland off Cape Desolation south of lvittuut. They found...

Competition Between Coral, Seaweed Occurs On A Chemical Scale
2014-01-09 06:32:58

April Flowers for redOrbit.com - Your Universe Online For one particular species of tropical seaweed, competition may have a high cost. Scientists investigating the chemical warfare that takes place on Fijian coral reefs have discovered that one species of seaweed increases its production of noxious anti-coral compounds when placed in contact with reef-building corals. The study, published in Proceedings of the Royal Society B, show that as this seaweed competes chemically with the...

Corals Keep Climate Record
2013-12-16 10:19:07

Brett Smith for redOrbit.com - Your Universe Online In addition to providing shelter and being an important part of a marine ecosystem, coral reefs can also serve as a record of long-term changes to the ecosystem. According to a new study published on Sunday in the journal Nature, an analysis of Pacific corals has revealed changes at the bottom of the marine food web observed in recent decades in the North Pacific Subtropical Gyre may have started over 150 years ago. The study team...

Long Island Barrier Still Intact After Hurricane Sandy

Alan McStravick for redOrbit.com – Your Universe Online On August 29 of last year, Hurricane Sandy, noted as the most powerful hurricane of the 2012 season, made landfall in southern New Jersey, wreaking havoc across much of the eastern seaboard. Residents of the area faced property destruction and crisis situations like flooding and massive, long-term power outages just in time for a particularly frigid autumn. Now more than a year out from the superstorm, a University of Texas led...

Economical Solutions For Maintaining Critical Delta Environments
2013-12-10 08:47:46

Woods Hole Oceanographic Institution Millions of people across the world live or depend on deltas for their livelihoods. Formed at the lowest part of a river where its water flow slows and spreads into the sea, deltas are sediment-rich, biodiverse areas, a valuable source of seafood, fertile ground for agriculture, and host to ports important for transportation. At least half of the deltas around the world are so-called “wave dominated deltas” – open to the sea and under the...

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...
