Marine Pollution Impact On Corals Is Harsh, But They Can Recover
2013-11-26 14:24:00

[ Watch the Video: Protection From Marine Pollution Would Help Coral Reefs Recover ] Brett Smith for redOrbit.com - Your Universe Online A new study on coral reefs from a team of Florida and Oregon researchers has found common marine pollution doubled the rate of disease among corals and more than tripled the amount of coral bleaching, an early sign of reef stress. According to the team’s report in Global Change Biology, a three-year, controlled exposure of corals to high levels of...

Abundant, Dominant Corals Still Face Threat Of Extinction
2013-11-16 06:48:46

April Flowers for redOrbit.com - Your Universe Online Scientists generally assume that corals do not face a risk of extinction unless they become very rare, or their range is restricted. A new study, published in the journal Bioscience, reveals that global changes in climate and ocean chemistry affect corals whether scarce or abundant, and often it is the dominant, abundant corals with wide distributions that are affected the most. A research team, led by Charles Birkeland from the...

A Changing Climate May Not Spell Doom For Coral Reefs After All
2013-10-30 09:18:53

April Flowers for redOrbit.com - Your Universe Online A new study from the National Oceanic and Atmospheric Administration (NOAA) and its academic partners reveals that coral reefs may be able to adapt to moderate climate warming, improving their chance of surviving through the end of this century, if there are large reductions in carbon dioxide emissions. The findings, published online in the journal Global Change Biology, also suggest corals have already adapted to part of the warming...

Coral Chemical Affects Climate
2013-10-24 15:24:33

Brett Smith for redOrbit.com - Your Universe Online Anyone who has ever been to the ocean knows that signature smell of sea water. One of the molecules responsible for that smell is actually derived from a chemical made by tiny coral animals called dimethylsulphoniopropionate (DMSP). According to a new study in the journal Nature, Australian marine scientists have discovered the first evidence that DMSP plays a major role in local climate. The molecule offers the coral animals cellular...

Drone Creates Detailed Coral Reef Maps
2013-10-16 15:47:05

[ Watch the Video: Coral Reef Mapping With The Help Of Drones ] Brett Smith for redOrbit.com - Your Universe Online The War on Terror may have given unmanned drones a bad name, but a research team from Stanford University just might be able to rehabilitate that image. Ved Chirayath, an aeronautics researcher, and Steven Palumbi, a marine biologist, have started using an unmanned drone and cutting-edge computer software to map and measure centuries-old corals. Equipped with several...

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...

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...
