Coral Bleaching Study Explains Different Responses To Climate Change
2013-04-24 12:24:35

Brett Smith for redOrbit.com - Your Universe Online When corals become stressed, they expel their symbiotic algae companions in a process known as “bleaching.” Corals can survive the bleaching, but it leaves them highly vulnerable and often results in die-off. As a changing climate threatens to bleach the corals of the world´s oceans on a massive scale, a team of researchers from Northwestern University has found that some corals facilitate bleaching through the...

Scientists Say More Large Ocean Wilderness Parks Needed
2013-04-15 08:43:45

ARC Centre of Excellence for Coral Reef Studies Leading international marine scientists have called for the protection of more, large marine wilderness areas in a bid to shield the world´s dwindling stocks of fish from destruction. Working in the world´s largest unfished marine reserve, the remote Chagos Archipelago in the central Indian Ocean, scientists from Australia and the US have shown there is a dramatic difference in the numbers, size and variety of fish compared with...

Picky Eaters Keep Endangered Coral Reefs Clean

[ Watch the Video: Picky Eater Fish Endanger Coral Reefs ] Peter Suciu for redOrbit.com — Your Universe Online Few pet owners would expect their dog or cat to clean up the house, and anyone who has ever camped in places such as Yellowstone Park knows that bears can visit and will leave a campsite in worse shape than they found it. Fish on the other hand could actually be doing some good in cleaning up coral reefs. A recent study conducted in the Fiji Islands found that four...

According to a new technical report, the effects of climate change will continue to threaten the health and vitality of U.S. coastal communities' social, economic and natural systems. The report, Coastal Impacts, Adaptation, and Vulnerabilities: a technical input to the 2013 National Climate Assessment, authored by leading scientists and experts, emphasizes the need for increased coordination and planning to ensure U.S. coastal communities are resilient against the effects of climate change....

Investigating How Corals Survive In The Hottest Reefs On The Planet
2013-02-01 14:48:45

National Oceanography Centre, Southampton (UK) Coral reefs are predicted to decline under the pressure of global warming. However, a number of coral species can survive at seawater temperatures even higher than predicted for the tropics during the next century. How they survive, while most species cannot, is being investigated by researchers at the National Oceanography Centre, Southampton (NOCS) and New York University Abu Dhabi (NYUAD). We tend to associate coral reefs with tropical...

Cape Cods Salt Marshes Are Under Threat
2013-01-26 05:59:46

Alan McStravick for redOrbit.com - Your Universe Online One of the iconic ecological features of Cape Cod in Massachusetts is the dominant form of coastal wetland in the region called salt marshes. Most typically, a salt marsh can be found behind a barrier beach and within estuarine systems. They have, over the previous 3,000 years, come into existence as a direct result of sea-level rise. Vegetation in the area primarily consists of saltmeadow cordgrass and, in lower marshes, smooth...

China´s coral reefs have suffered a devastating 80 per cent decline in recent decades, driven mainly by the country´s unrestrained economic development, according to a new international scientific study. The first comprehensive survey of the state of corals along mainland China and in the South China Sea reports a grim picture of decline, degradation and destruction resulting from coastal development, pollution and overfishing. A new study by Professor Terry Hughes and Matthew...

Government Agency Proposes Dozens Of Coral Species For Endangered Species Act
2012-12-03 16:06:58

Lee Rannals for redOrbit.com — Your Universe Online A new Endangered Species Act listings proposed by the National Oceanic and Atmospheric Association (NOAA) would cover 66 coral species found in the Pacific and the Caribbean. NOAA said that in 2009, it received a petition to list 83 species of reef-building corals under the ESA from the Center for Biological Diversity. The organization found that the Center presented substantial information indicating a listing under the ESA...

Scientists Discover Three New Arthropod Species In Spain
2012-11-28 13:35:13

April Flowers for redOrbit.com - Your Universe Online Three new collembolan species have been discovered in the Maestrazgo caves in Teruel, Spain, by a team of scientists from the University of Navarra and the Catalan Association of Biospeleology. The team published descriptions of the new species — minute animals belonging to one of the most ancient animal species on the planet — in the journal Zootaxa. Biospeleology is the study of life in caves, karst formations 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...
