Ice Sheet Collapse And Sea-level Rise At The Bølling Warming 14,600 Years Ago
2012-04-06 04:23:00

International scientists have shown that a dramatic sea-level rise occurred at the onset of the first warm period of the last deglaciation, known as the Bølling warming, approximately 14,600 years ago. This event, referred to as Melt-Water Pulse 1A (MWP-1A), corresponds to a rapid collapse of massive ice sheets 14,600 years ago and resulted in global sea-level rise of ~14 m. These findings are published in the 29 March 2012 issue of the journal Nature (Volume 483, Issue 7391)....

Extreme weather such as hurricanes, torrential downpours and droughts will become more frequent in pace with global warming. Consequently, this increases the risk for species extinction, especially in bio diverse ecosystems such as coral reefs and tropical rainforests. Human impact means that flora and fauna become extinct at a rate 100-1000 times higher than normal. Climate change has been deemed as one of the main causes of species depletion. A research team in theoretical biology at...

Anoxia and toxic sulfide are a menace to coral tissue Researchers of the Max Planck Institute for Marine Microbiology along with Australian colleagues, have examined corals from the Great Barrier Reef affected by the Black Band Disease and identified the critical parameters that allow this prevalent disease to cause wide mortality of corals around the world. Corals infected with Black Band show a characteristic appearance of healthy tissue displaced by a dark front, the so called Black...

Ancient Civilizations Reveal Ways To Manage Fisheries For Sustainability
2012-03-24 03:06:20

In the search for sustainability of the ocean's fisheries, solutions can be found in a surprising place: the ancient past. In a study published on March 23 in the journal Fish and Fisheries, a team of marine scientists reconstructed fisheries yields over seven centuries of human habitation in Hawaii and the Florida Keys, the largest coral reef ecosystems in the United States, and evaluated the management strategies associated with periods of sustainability. The results surprised them....

Marine Protected Areas Prove To Be Vital Aspect Of Green Turtle Sustainability
2012-03-21 05:08:51

Ryan Parson for RedOrbit.com Some sea turtles appear to be reaping the benefits of government designated areas of bodies of water, known as Marine Protected Areas (MPAs). A recent study published in the journal Global Ecology and Biogeography suggests that the MPAs are playing a key role in the support and nourishment of the Green turtle. According to the National Marine Fisheries Service, all six species of sea turtles that inhabit US waters are currently listed under the Endangered...

Management of fisheries at the community level can help curb overfishing and the ℠tragedy of the commons´ which is driving humans to decimate the planet´s dwindling fish stocks, an international scientific team says. The positive finding comes from the world´s largest field investigation of 42 co-managed coral reef fisheries in five countries spread across the Indian and Pacific oceans. The team of 17 scientists from eight nations concluded that partnerships between...

Evidence In Bahamas And Bermuda Suggests Increased Rise In Sea Levels
2012-03-15 11:45:55

Scientists are now predicting sea levels will climb another several inches -- or even a few feet -- by the year 2100, according to recent studies. Studying cliffs and ancient reefs on the sub-tropical islands of the Bahamas and Bermuda, scientists are investigating global sea rise and comparing these results against data from more than a century ago. The Bahamas and Bermuda have been attracting fossil hunters for many years. The land on the Bahamas, for example, is built on a foundation...

Sharks More Prevalent In Protected Areas, Study Claims
2012-03-10 06:22:33

Using data collected from over 200 baited remote underwater video (BRUV) cameras, scientists have discovered that Caribbean reef sharks are more abundant in marine reserves than in areas where fishing is allowed. The BRUV cameras, affectionately dubbed "chum cams," were placed both inside and outside aquatic reserve areas on the Mesoamerican Barrier Reef in the Caribbean Sea by researchers from the Stony Brook University Institute for Ocean Conservation Science. Their goal was to test a...

Future Of Energy Source Is Seaweed, Researchers Say
2012-03-05 13:30:46

Researchers are looking to the sea in their search for safer and cleaner future alternative energy sources. The team from various institutions and organizations is developing methods for growing and harvesting seaweed as a source of renewable energy. Professor Avigdor Abelson of Tel Aviv University's Department of Zoology believes that not only can the macroalgae be grown unobtrusively along coastlines, they can also help clear the water of excessive nutrients. Pollution caused by...

Ocean Acidification Rapid Compared To Ancient Times
2012-03-02 13:49:09

The world´s oceans may be acidifying more rapidly than they have at any time in the past 300 million years due to high levels of pollution, according to research published this week in the journal Science. Researchers, led by Columbia University´s Lamont-Doherty Earth Observatory and the University of Bristol, assessed a number of climate change events in Earth´s history, including an asteroid impact that wiped out the dinosaurs 65 million years ago. They warn that too...

Black Sea Urchin, Diadema antillarum
2013-11-06 11:22:21

Diadema antillarum, known also as the Lime Urchin, the Long-Spined Sea Urchin, or the Black Sea Urchin, is a species of sea urchin belonging to the family Diadematidae. It is characterized by its extremely long black spines. This species is the most plentiful and significant herbivore on the coral reefs of the western Atlantic and Caribbean basin. Then the population of these sea urchins is at a healthy level, they’re the main grazers which prevent algae overgrowth of the reef....

Synaptula lamperti
2013-11-04 09:27:28

Synaptula lamperti is a species of sea cucumber belonging to the family Synaptidae within the phylum Echinodermata, located on coral reefs within the Indo-Pacific region. The echinoderms are marine invertebrates and they include the sea urchins, sea cucumbers, and starfish. They’re radially symmetric and have a water vascular system that is driven by hydrostatic pressure, making them able to move around via numerous suckers known as tube feet. Sea cucumbers are typically leathery,...

Diadema setosum
2013-04-30 15:23:43

Diadema setosum is a species of sea urchin that can be found in Indo-Pacific waters. Its range extends from the Red Sea to coasts of Australia in the east, and from Japan in the north to the east coast of Africa in the south. There have been a few individuals found outside of this natural range, leading experts to believe that it was introduced by natural or manmade causes. Two individuals were found off the coast of the Kaş peninsula in Turkey in 2006. These individuals represent the first...

Lampert's Sea Cucumber, Synaptula lamperti
2013-04-30 15:18:06

Synaptula lamperti is a species of sea cucumber that can be found in the waters of the Indo-Pacific. Its range includes the coastal waters of Papua New Guinea, the Philippines, Indonesia, and Micronesia. It does not have the tube feet, which are common to other species of sea cucumber, instead moving around by using a small grouping of pinnate feeding tentacles, which are always moving. It can also move by using the small, hook-like bones found along its body, attaching itself to the sea...

Black Sea Urchin, Diadema antillarum
2013-04-30 12:59:49

The black sea urchin (Diadema antillarum), also known as the lime sea urchin or the long-spined sea urchin, is a species that can be found in the Caribbean basin and the western waters of the Atlantic Ocean. It prefers to inhabit coral reefs in these areas and resides at depths of up to 32.8 feet. This species has a test, or outer shell, that is similar that of most species of sea urchin. However, this species has longer spines, a trait from which it derived one of its common names. These...
