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...

Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world’s seagrass meadows. Seagrass meadows, such as eelgrass or Halophila, grow along most of the world's coasts where they provide important habitats for a wide variety of life...

U.S. National Oceanic and Atmospheric Administration (NOAA) has awarded a Phase II - Small Business Innovative Research (SBIR) grant to Polestar Technologies to develop methods of monitoring ocean acidification and coral reef decimation. Needham Heights, MA (PRWEB) September 28, 2013 The rapid decline of living coral reefs has been a major concern of oceanographers and aqua-agriculturists worldwide. The well-being of our planet is directly related to the health of our oceans. The White...

A new report looks at how extreme weather and an increase in non-point source pollution from agriculture and failing septic systems are spurring the spread of harmful algal blooms. It includes a first-of-its-kind national online map showing that 21 states issued health advisories related to toxic algae at 147 lakes and rivers this summer. Ann Arbor, Michigan (PRWEB) September 26, 2013 Summer should be a time for fishing, boating and swimming with family on our nation’s lakes. Yet...

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...

Ocean Management Essential to Life and Our Future Generations (PRWEB) September 11, 2013 Accounting for seventy one percent of planet Earth, the ocean is a natural ecosystem that not only sustains marine life; it quintessentially supports a mammoth amount of the economy in America. Fisheries, tourism, and recreation all depend on the ocean for its resources. Without it, billions of dollars are at stake and the delicate dance of the economy’s balance is at risk. The ocean needs to be...

X Prize For Measuring Ocean Health
2013-09-10 11:15:29

Brett Smith for redOrbit.com - Your Universe Online Global warming alarmists and deniers alike can probably agree on at least one thing: Scientists need the most accurate data and tools to make their climate assessments. In pursuit of more accurate climate data, the X Prize Foundation has announced a $2-million competition designed to kick-start technology innovations surrounding the accurate measuring of oceanic pH. Climatologists have been warning that the world's oceans are...

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...

Predicting Fish Habitats Months In Advance With New Ocean Forecast
2013-08-31 07:53:32

April Flowers for redOrbit.com - Your Universe Online As meteorological science advances, we have all become used to long-term weather forecasts, such as predicting what the coming winter might bring. A new study from the University of Washington and federal scientists, however, has developed the first long-term forecast of conditions that matter for Pacific Northwest fisheries. “Being able to predict future phytoplankton blooms, ocean temperatures and low-oxygen events could help...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

A salp is a barrel-shaped, free-floating tunicate (any living organism which has a saclike body enclosed in a thick membrane or tunic with two openings or siphons for the ingress and egress of water). It moves by contracting which pumps water through its body. The salp strains the water with internal feeding filters as it goes through the body. It consumes phytoplankton that are strained from the water. Salps are common throughout equatorial, temperate, and colder seas. They are most often...

The South American pilchard, Sardinops sagax, is a sardine of the Family Clupeidae, the only member of the genus Sardinops, found in the indo-Pacific oceans. Their length is up to 15.75 in (40 cm). It has a number of other common names: Australian pilchard, Blue pilchard, Blue-bait, Californian pilchard, Chilean sardine, Japanese pilchard, Pacific sardine, and Southern African pilchard. The South American pilchard is a coastal species that forms large schools. Coloration is blue green on...

  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
