LANDOVER, Md., Dec. 12, 2012 /PRNewswire-USNewswire/ -- From Nov 13(th) to December 11(th) 2012 a team of scientists from the Khaled bin Sultan Living Oceans Foundation, joined by visiting researchers, conducted hundreds of underwater survey dives on reefs in the Tuamotu Archipelago of French Polynesia. This study follows research the team did earlier in the Society Islands and has produced some noticeable differences between the two island groups. "We basically repeat the same survey...

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...

NEW YORK, Nov. 27, 2012 /PRNewswire-iReach/ -- Artist Paul Hunt of Brooklyn, NY has launched a 30-day Kickstarter campaign which will run from November 27 through December 26. The purpose is to raise funds that will enable the completion of his multimedia installation art project. He hopes that his work will encourage people to gain an understanding of the importance of coral reefs, visit these impressive sea creatures for themselves, support programs that clean the ocean and influence...

The terms “gas” and “sea” for many will invoke associations of reserves, business, and a lot of money. Whatever the association, most of the efforts in Israel´s energy field are being directed at gas buried deep under the Mediterranean seabed. Now a new geophysical study, the first of its kind in Israel, has uncovered a system of active gas springs in the Haifa Bay seabed, at relatively shallow depths, only a few dozen meters below the surface. The study,...

Rapid advances in the new and developing field of restoration sedimentology will be needed to protect the world's river deltas from an array of threats, Indiana University Bloomington geologist Douglas A. Edmonds writes in the journal Nature Geoscience. The commentary, published this week in the November issue, addresses the fact that land is disappearing from river deltas at alarming rates. And deltas are extraordinarily important: They are ecologically rich and productive, and they are...

Sweden’s Säcken Reef Facing Death
2012-10-23 21:13:37

Alan McStravick for redOrbit.com — Your Universe Online The Säcken reef in the Koster Fjord in Sweden is that country´s last remaining cold-water coral reef and it is under a distinct threat of extinction. Like the more common warm-water reefs, cold-water reefs are known for their rich biological diversity. With the Säcken reef in distress, researchers from the University of Gothenburg have started a restoration project extracting healthy corals...

The number of leisure boats along the Swedish West Coast has risen dramatically over the last 20 years, resulting in a risk that the inner archipelago might be destroyed. These are the findings of new research from the University of Gothenburg, Sweden. In Sannäs Fjord, a silled fjord to the north of Grebbestad in Bohuslän, researchers from the University of Gothenburg have studied the marine environment in the inner archipelago and built a treatment plant for...

Salt Marshes Disappearing
2012-10-18 21:05:22

Brett Smith for redOrbit.com — Your Universe Online [ Watch the Video: Why Our Salt Marshes Are Falling Apart ] Salt marshes along the eastern coast of the United States have been disappearing over the past two decades and a group of American researchers led by Linda Deegan of the Marine Biological Laboratory (MBL) in Woods Hole, Mass. has shown that an influx of phosphorus- and nitrogen-based nutrients is partly to blame. These nutrients come from untreated sewage systems and...

Coral Can Have Too Much Of A Good Thing
2012-10-15 04:54:29

redOrbit Staff & Wire Reports - Your Universe Online While the single-celled algae that live inside corals typically play a vital role in keeping the reefs healthy, a new study suggests that an overabundance of the symbiotic organisms could have a negative effect on them. According to scientists at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science, these algal symbionts provide corals with the energy needed to build larger reef frameworks. When...

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...
