Jellyfish Numbers Shifting Climate Patterns
2013-10-24 15:47:31

Brett Smith for redOrbit.com - Your Universe Online Every month, 8 to 12 days after each full moon, Waikiki Beach is invaded by large numbers of box jellyfish. After witnessing the phenomenon countless times, Honolulu lifeguard Landy Blair, in conjunction with researchers at the University of Hawaii at Mānoa, started tracking the numbers of jellyfish that invade the beach with each cycle. Over 170 full moons after they began, the team’s published findings in the latest issue of PLOS...

Tiny Sea Creatures Headed For Extinction, Could Take Local Fisheries With Them
2013-10-18 09:46:54

Deakin University A species of one of the world’s tiniest creatures, ocean plankton, is heading for extinction as it struggles to adapt to changes in sea temperature. And it may take local fisheries with it. Research led by Deakin University (Warrnambool, Australia) and Swansea University (UK) has found that a species of cold water plankton in the North Atlantic, that is a vital food source for fish such as cod and hake, is in decline as the oceans warm. This will put pressure on the...

Phytoplankton In The Southern Ocean
2013-09-19 04:45:00

[ Watch the Video: Phytoplankton Observed By NASA Satellites ] April Flowers for redOrbit.com - Your Universe Online Until now, NASA satellites might have missed as much as 50 percent of the phytoplankton in the Southern Ocean. This would make it far more difficult to estimate the potential carbon capture of this vast area of the sea. A new study from the University of Tasmania's Institute for Marine and Antarctic Studies (IMAS), published in the Journal of Geophysical Research, has...

Tiny Plankton May Have Big Impact On Climate
2013-09-13 14:28:37

European Geosciences Union As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed. An international team of marine scientists has found that the smallest plankton groups thrive under elevated carbon dioxide (CO2) levels. This could cause an imbalance in the food web as well as decrease ocean CO2 uptake, an important regulator of global climate. The results of the study, conducted off the coast of Svalbard, Norway, in 2010, are now compiled in a special...

Rising Temperatures Could Upset Natural Ocean Cycles
2013-09-09 04:15:09

redOrbit Staff & Wire Reports - Your Universe Online Rising water temperatures will have an adverse impact on plankton, serving as the catalyst for a series of events that will upset the balance of essential oceanic chemical cycles, according to new research published in Sunday’s edition of the journal Nature Climate Change. Scientists from the University of East Anglia (UEA) in the UK examined the impact that ocean temperatures can have on the plankton ecosystems found in the...

Scientists Create Global Atlas On Oceanic Plankton
2013-07-19 10:05:40

April Flowers for redOrbit.com - Your Universe Online An international group of scientists has created a global atlas of oceanic plankton -- from bacteria to krill -- by recording times, places and concentrations of the organism's occurrences. Over 70 percent of the world's surface is covered by the oceans. Compared with terrestrial ecosystems, the animals and plant species of the oceans have been researched relatively little. Because of this, the knowledge base concerning the...

Ancient Algal Bloom Mystery Solved
2013-07-15 15:05:24

Brett Smith for redOrbit.com - Your Universe Online An ancient bloom of life that occurred just after the last ice age isn't what it seemed at first, according to new research in the journal Nature Geoscience. Scientists had long believed that the bloom, which occurred around 14,000 years ago, was spurred by rising sea levels washing iron into the ocean. However, the new study suggested that a "perfect storm" of conditions allowed for the bloom to happen, and not simply the abundance of...

Phytoplankton Ocean Turbulence Social Mixers
2013-07-15 12:58:35

[Watch the video: Phytoplankton Social Mixers] Lee Rannals for redOrbit.com - Your Universe Online The motility of phytoplankton allows the tiny ocean plants to determine their fate in ocean turbulence, according to scientists at MIT and Oxford University. Researchers wrote in the journal Nature Communications that the individual vortices that make up ocean turbulence are like social mixers for phytoplankton. This social mixer brings similar cells into close proximity, helping to...

Protecting Spiny Lobster Larvae
2013-06-13 13:04:09

University of Miami Rosenstiel School of Marine & Atmospheric Science The commercial value of spiny lobster (Panulirus argus) in the Caribbean reaches $1 billion annually, thus making it one of the most valuable fisheries in the region. In a new study of this iconic species, Ph.D. candidate Andrew Kough and Dr. Claire Paris of the Biophysical Interactions Lab at the University of Miami Rosenstiel School of Marine & Atmospheric Science, in collaboration with Dr. Mark Butler from Old...

A new study on the feeding habits of ocean microbes calls into question the potential use of algal blooms to trap carbon dioxide and offset rising global levels. These blooms contain iron-eating microscopic phytoplankton that absorb C02 from the air through the process of photosynthesis and provide nutrients for marine life. But one type of phytoplankton, a diatom, is using more iron that it needs for photosynthesis and storing the extra in its silica skeletons and shells, according to an...

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...
