Impact From Humans Felt On Black Sea Long Before Industrial Era
2012-09-04 14:44:23

When WHOI geologist Liviu Giosan first reconstructed the history of how the Danube River built its delta, he was presented with a puzzle. In the delta´s early stages of development, the river deposited its sediment within a protected bay. As the delta expanded onto the Black Sea shelf in the late Holocene and was exposed to greater waves and currents, rather than seeing the decline in sediment storage that he expected, Giosan found the opposite. The delta continued to grow. In fact,...

Arctic Waters Invaded By Tropical Plankton
2012-07-25 08:29:52

Researchers see natural cycle; but questions arise on climate change For the first time, scientists have identified tropical and subtropical species of marine protozoa living in the Arctic Ocean. Apparently, they traveled thousands of miles on Atlantic currents and ended up above Norway with an unusual–but naturally cyclic–pulse of warm water, not as a direct result of overall warming climate, say the researchers. On the other hand: arctic waters are warming rapidly, and such...

Ocean Fertilization Suffocates Carbon, Reduces Climate Change
2012-07-19 10:19:23

Lawrence LeBlond for redOrbit.com - Your Universe Online The negative impact of climate change might be avoided by dumping massive amounts of iron into the world´s oceans, which smothers carbon dioxide for centuries, according to an international team of researchers who have recently published results of an ocean iron fertilization experiment (EIFEX) carried out in 2004. The new study, published in the science journal Nature, shows that sowing the ocean with iron particles sucks up...

The results, which were published in the scientific journal Nature, provide a valuable contribution to a better understanding of the global carbon cycle An international research team has published the results of an ocean iron fertilization experiment (EIFEX) carried out in 2004 in the current issue of the scientific journal Nature. Unlike the LOHAFEX experiment carried out in 2009, EIFEX has shown that a substantial proportion of carbon from the induced algal bloom sank to the deep sea...

North Atlantic Phytoplankton Bloom Triggered By Eddies
2012-07-06 05:16:57

redOrbit Staff & Wire Reports - Your Universe Online Scientists studying the annual growth of tiny plants in the North Atlantic Ocean have discovered that this year´s growth spurt began before the sun was able to offer the light needed to fuel the yearly phenomenon. The annual growth spurt of plankton, which is known as the North Atlantic Bloom, takes place each Spring, and results in an immense number of phytoplankton bursting into existence -- first "greening," then...

The pico is a very small unit, even smaller than the nano as it is the equivalent of 10-12. The biologist Aitor Alonso has devoted himself to studying green algae of this imperceptible size existing in the Bilbao estuary, paying particular attention to the area beyond the Nervión estuary. This has enabled him to identify six genera and eleven nano- and picoplanktonic species that until now had not been catalogued in these waters. He has also put forward some measures designed to...

Foundational Concept Of Ecology Tested With Experiment

Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other “organisms” their assigned plant or animal interacts with in some way. Once an ecosystem web has been created, the teacher describes an event that affects one “organism.” That...

[ Watch the Video ] redOrbit Staff & Wire Reports NASA officials announced on Thursday that an expedition they sponsored had uncovered a massive bloom of phytoplankton in the ice-capped waters of the Arctic Ocean -- a discovery which the U.S. space agency has called "as dramatic and unexpected as finding a rainforest in the middle of a desert." The findings, which came as part of Impacts of Climate on EcoSystems and Chemistry of the Arctic Pacific Environment (ICESCAPE)...

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife. In a study published May 23 in the journal...

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...
