Latest Biological oceanography Stories
The phrase "forest loss" or "deforestation" brings to mind negative impacts such as a loss of habitat, the release of greenhouse gases, soil erosion and economic hardships. Such negative outcomes are seen in many of the world's forests.
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fueling further climate change, a study suggests.
Phytoplankton—tiny, photosynthetic organisms—are essential to life on Earth, supplying us with roughly half the oxygen we breathe. Like all other life forms, phytoplankton require the element phosphorus to carry out critical cellular activity, but in some parts of the world’s ocean, P is in limited supply.
New research reveals how the algae behind red tide thoroughly disables – but doesn't kill – other species of algae. The study shows how chemical signaling between algae can trigger big changes in the marine ecosystem.
A newly-discovered source of oceanic bioavailable iron could have a major impact on our understanding of marine food chains and global warming.
The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed
Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.
ForeverGreen Unveils New Product- SolarStrips will be available in over 160 countries Orem, Utah (PRWEB) April 02, 2014
Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe.
In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich.
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...
