The icy seas between Australia and Antarctica could become a money generator by engineering nature to soak up carbon dioxide and then selling carbon credits worth millions of dollars. But many scientists believe the concept of using nature to mop up mankind's excess CO2 to fight global warming is fraught with risk and uncertainty. An Australian research body suggests more research is needed before commercial ventures are allowed to fertilize oceans on a large scale and over many years to...

Researchers in Germany and Canada reported on Thursday that climate change could effect the global food chain by supporting animals with short life spans rather than their larger long-lived predators. Researchers noted that animals showed widely differing "thermal windows" -- a range of temperatures in which they best feed, grow and reproduce, meaning that global warming would have a varying effect on each species. "Climate change will favor species with wide thermal windows, short life...

Diatoms, mighty microscopic algae, have profound influence on climate, producing 20 percent of the oxygen we breathe by capturing atmospheric carbon and in so doing, countering the greenhouse effect. Since their evolutionary origins these photosynthetic wonders have come to acquire advantageous genes from bacterial, animal and plant ancestors enabling them to thrive in today's oceans. These findings, based on the analysis of the latest sequenced diatom genome, Phaeodactylum tricornutum, are...

A team of scientists is studying the complex ocean upwelling process by mimicking nature "“ pumping cold, nutrient-rich water from deep within the Pacific Ocean and releasing it into surface waters near Hawaii that lack the nitrogen and phosphorous necessary to support high biological production. The researchers are harnessing the power of the ocean to conduct their experiments, using the up-and-down motion of waves to pump deep water to the surface. Their next step is to create a pump...

By BINA VENKATARAMAN By Bina Venkataraman The New York Times Many coastal areas of the world's oceans are being starved of oxygen at an alarming rate, with vast stretches along the seafloor depleted of it to the point where they can barely sustain marine life, researchers are reporting. The main culprit, scientists say, is nitrogen-rich nutrients from crop fertilizers that spill into coastal waters by way of rivers and streams. A study to be published today in the journal Science...

By Anonymous The brilliant beamlines of the Australian Synchrotron are finding a host of environmental applications, from studying the chemistry of the upper atmosphere to developing better catalysts for hydrogen production. Detecting and precisely locating specific atoms and molecules is one of the things synchrotrons do best. That makes them very useful for many environmental applications. The Australian Synchrotron's microspectroscopy beamline, for instance, can be used as a probe to...

A Giant sea monster was brought back to life at a nature reserve to celebrate National Marine Week. Theatre group the Desperate Men brought a life-size model of a sea sturgeon, once native to the Humber Estuary, to Far Ings Nature Reserve, in Barton-Upon-Humber. Children who came to see the monster were delighted by the play and able to make their own sea creatures, including flying fish. Ellen Frost (10), of Forkedale, Barton, said: "I felt sorry for the sturgeon and hope it can find...

By Elisabeth Rosenthal Blue patrol boats crisscross the swimming areas of beaches here with their huge nets skimming the water's surface. The yellow flags that urge caution and the red flags that prohibit swimming because of risky currents are sometimes topped now with blue ones warning of a new danger: swarms of jellyfish. In a period of hours during a day a couple of weeks ago, 300 people on Barcelona's bustling beaches were treated for stings, and 11 were taken to hospitals. From Spain...

A seasonal bloom of ocean plankton is pulling more carbon dioxide than previously thought from the atmosphere into the Atlantic Ocean, U.S. researchers said. The bloom -- nurtured by the Amazon River -- may be enough to turn the tropical Atlantic from a net source of atmospheric carbon into a net carbon sink that removes carbon dioxide from the atmosphere, New Scientist reported. Ajit Subramaniam, an oceanographer at Lamont-Doherty Earth Observatory in Palisades, N.Y., and his colleagues...

More than 93 million years ago, researchers say undersea volcanic activity caused mass extinction in the worlds' oceans. During the late Cretaceous Period, the supposed "anoxic event" starved oxygen from the ocean depths and wiped out millions of marine organisms. Researchers from the University of Alberta, Canada, published their findings in the journal Nature. They found a telltale signature of underwater volcanism in rocks dating to the period. Researchers say during the undersea...

Mediterranean feather star, Antedon mediterranea
2013-05-18 06:26:42

The Mediterranean feather star is a filter feeder that obtains food by straining suspended matter and food particles from water. The star has a stalk that has up to forty tendrils, (threadlike organs) which help the star cling to hard surfaces. The “body” of the star is called a calyx and is shaped like a small cup. This calyx is surrounded by feathery pinnules bearing arms. These arms are quite unique in the fact that they can regenerate if one should get broken off; these arms extend to...

Chilean Sea Urchin, Loxechinus albus

Image Caption: Chilean Sea Urchin, Loxechinus albus. Credit: Dentren/Wikipedia (CC BY-SA 3.0) The Chilean sea urchin (Loxechinus albus) is a species that can be found along the coastlines of Chile and Peru. It is typically found in shallow waters at or below the tide level, buried in sand or lying just on top of it. This species is often associated with Macrocystis pyrifera, a type of kelp. It is most often found in more open spaces. The Chilean sea urchin can reach an average width of...

The White-spotted jellyfish is also known as the Australian spotted jellyfish (Phyllorhiza punctata). The jellyfish feeds primarily on assorted snail species and thrives in the southwestern Pacific. The bell of the White-spotted jellyfish averages 17-19 inches in diameter but there had been a maximum reported size of 24 inches. However, on Sunset Beach in North Carolina in October, 2007, a White-spotted jellyfish was found on the shore measuring in at 28 inches, perhaps the largest to...

The Tarakihi or Jackass morwong, Nemadactylus macropterus, is a morwong of the genus Nemadactylus found off the coast of southern Australia, the Atlantic coast of South America, and all around New Zealand to depths of about 1312.34 ft (400 m). Its length is between 11.81 and 23.62 in (30 and 60 cm). The Tarakihi is similar to the Porae but with a silver body color and a distinctive black saddle immediately behind the head. Their diet is similar to that of the Porae but also with a wide...
