Bondi Beach Closed Due To Algae Bloom
2012-11-27 19:59:28

Lee Rannals for redOrbit.com — Your Universe Online Tourists at Australia's Bondi Beach were surprised to see what looked like blood-soaked water heading their way this week. Bondi Beach is a popular tourists destination around Sydney Australia, but the area had to be closed after a huge algal bloom took over some of the area's waters. Ten News Sydney reported that despite the warnings, a number of beachgoers were still venturing into the water and swimming through the red...

Ocean Acidification Threatens Antarctic Marine Wildlife
2012-11-26 05:01:08

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has uncovered the first evidence that marine creatures living in the Antarctic region are being affected by ocean acidification. That evidence was discovered in 2008, when researchers from the British Antarctic Survey (BAS), the University of East Anglia (UEA), the Woods Hole Oceanographic Institution (WHOI) and the National Oceanic and Atmospheric Administration (NOAA) observed that the shells...

Movement Of Seawater Affects How Marine Bacteria Absorb Organic Material
2012-11-01 14:39:18

National Science Foundation New research shows that ocean turbulence directly affects the ability of microscopic marine organisms to recycle organic material back into the food web. Results of the study are published in this week's issue of the journal Science. Scientists John Taylor of Cambridge University and Roman Stocker at MIT found that there's a relationship between the natural movement of water in the ocean and the ability of marine bacteria to act as recyclers. "The...

Warming Oceans Will Play Major Role In Less Phytoplankton Diversity
2012-10-26 07:33:14

Lawrence LeBlond for redOrbit.com - Your Universe Online Phytoplankton (plant wanderers), organisms that exist in the sunlit layer of the world´s oceans, are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important organisms, further impacting climate change. Since phytoplankton play a major role in the food chain and the world´s carbon, nitrogen and phosphorous cycles, a significant...

Fish Poop May Be Critical To Ocean Carbon Cycle
2012-10-11 12:28:11

Alan McStravick for redOrbit.com - Your Universe Online Professor Deborah Steinberg of the Virginia Institute of Marine Science (VIMS) has dedicated her professional life to investigating crustaceans and their role in the “biological pump,” which is the process by which marine life transports carbon dioxide from the atmosphere and ocean´s surface to the deep sea. This cycle removes the carbon to a depth where it contributes nothing to global warming. In a new study...

Scientists at the University of Rhode Island's Graduate School of Oceanography have made the first observation of a predator avoidance behavior by a species of phytoplankton, a microscopic marine plant. Susanne Menden-Deuer, associate professor of oceanography, and doctoral student Elizabeth Harvey made the unexpected observation while studying the interactions between phytoplankton and zooplankton. Their discovery will be published in the September 28 issue of the journal PLOS ONE. "It...

Coral Reefs Will Suffer If Climate Change Goes Unchecked
2012-09-17 12:17:18

Brett Smith for redOrbit.com - Your Universe Online Time may be running out for the world´s coral reefs which could be severely victimized by rising global temperatures and carbon dioxide levels, according to a new report in Nature Climate Change. "Our findings show that under current assumptions regarding thermal sensitivity, coral reefs might no longer be prominent coastal ecosystems if global mean temperatures actually exceed 2 degrees Celsius (3.6 Fahrenheit) above the...

April Flowers for redOrbit.com - Your Universe Online "Out with the old and in with the new" is an adage we have all heard and probably lived by in this world of fast changing technology and fads.  But some tiny sea critters are showing us, newer isn't always better. Rhabdopleurids are small worm shaped animals that live on the ocean floor.  They build tube like homes of collagen on the shells of dead clams.  Rhabdopleurid colonies are small, and they are definitely not...

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,...

Life in the world´s oceans faces far greater change and risk of large-scale extinctions than at any previous time in human history, a team of the world´s leading marine scientists has warned. The researchers from Australia, the US, Canada, Germany, Panama, Norway and the UK have compared events which drove massive extinctions of sea life in the past with what is observed to be taking place in the seas and oceans globally today. Three of the five largest extinctions of the past...

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...
