Latest Biological oceanography Stories
During a summer expedition to the deepest region on the planet, the Mariana Trench, a team of researchers and engineers witnessed a breed of giant amoebas known as xenophyophores living at depths that had never been recorded before.
The tiny phytoplankton Emiliania huxleyi, invisible to the naked eye, plays an outsized role in drawing carbon from the atmosphere and sequestering it deep in the seas.
With toxic algal blooms — which can increase the amount of harmful toxins in the shellfish that California residents consume — ramping up in frequency and severity locally, scientists at USC have developed a new algae monitoring method in hopes of one day being able to predict when and where toxic "red tides" will occur.
Unprecedented algae growth in some lakes could be linked to the decline of water calcium levels and the subsequent loss of an important algae-grazing organism that helps keep blooms at bay.
Changes in ocean chemistry due to increased carbon dioxide (CO2) emissions are expected to damage shellfish populations around the world, but some nations will feel the impacts much sooner and more intensely than others.
Census of Marine Life reports in anthropogenic impact on deep sea.
During the 1970s and 1980s, researchers and policymakers became increasingly worried about multiple consequences of acidic emissions of sulfur dioxide and nitrogen oxides from the stacks of power stations, and eventually they were controlled.
Just as corn and peanuts stunned the world decades ago with their then-newly discovered multi-beneficial uses and applications, Texas AgriLife Research scientists in Corpus Christi think microalgae holds even more promise.
Zooplankton can use specialized adaptations that allow them to hide from predators in areas of the ocean where oxygen levels are so low almost nothing can survive - but they may run into trouble as these areas expand under climate change.
A new discovery reveals that the shrimp-like creature at the heart of the Antarctic food chain could play a key role in fertilising the Southern Ocean with iron â€“ stimulating the growth of phytoplankton (microscopic plant-like organisms).
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...
