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...

Pipeline Wave Frozen In Time
2013-07-23 05:40:15

April Flowers for redOrbit.com - Your Universe Online A team of scientists from the Universidad Carlos III of Madrid (UC3M) and the University of California - San Diego (UC San Diego) have created a static pipeline wave in a laboratory. The wave has a crest that moves neither forward nor backward, which will allow improvements in boat and seaport designs. The wave will also allow analysis of how carbon dioxide exchange between the ocean and the atmosphere occurs. The study findings are...

Crustacean Sand-dwellers Suffering Localized Extinctions In Southern California
2013-07-18 11:14:11

University of California - Santa Barbara Two types of small beach critters -- both cousins of the beloved, backyard roly-poly -- are suffering localized extinctions in Southern California at an alarming rate, says a new study by UC Santa Barbara scientists. As indicator species for beach biodiversity at large, their disappearance suggests a looming threat to similar sand-dwelling animals across the state and around the world. Led by David Hubbard and Jenifer Dugan of UCSB's Marine...

Coastal Storm Damage Not As Severe Thanks To Mother Nature
2013-07-18 10:28:51

April Flowers for redOrbit.com - Your Universe Online People and property along coastal regions are being placed at greater risk by extreme weather, sea-level rise and degraded coastal systems. A new study by scientists with the Natural Capital Project at the Stanford Woods Institute for the Environment shows that natural habitats such as dunes and reefs are critical to protecting millions of US residents and billions of dollars in property from coastal storms. The study, published...

Buried Seawall Helped Protect New Jersey From Hurricane Sandy
2013-07-17 08:53:32

April Flowers for redOrbit.com - Your Universe Online Bay Head and Mantoloking are residential beach communities that sit side-by-side on a narrow barrier island that separates the Atlantic Ocean and Barnegat Bay in Ocean County, New Jersey. Someone traveling between Mantoloking into Bay Head before Hurricane Sandy landed on October 29, 2012, would have noticed few changes in residential development, dunes, beaches and shoreline between the two towns. The important difference was...

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...
