Latest Biological oceanography Stories
University of Miami scientists are using the geologic record of corals to understand how reef ecosystems might respond to climate change.
A team of scientists in the United Kingdom and the United States has warned that the native fauna and unique ecology of the Southern Ocean, the vast body of water that surrounds the Antarctic continent, is under threat from human activity.
The passage of icebergs through surface waters changes their physical and biological characteristics.
Research can help assess impacts of climate change, other threats to coral reef ecosystems.
Ongoing climate-driven changes to the Arctic sea-ice could have a significant impact on the blooming of tiny planktonic plants with important implications for the Arctic ecosystem.
Phytoplankton peak arising up to 50 days early, with unknown impacts on marine food chain and carbon cycling.
Diatoms account for a large proportion of the phytoplankton found in the water, and live both in the open sea and in freshwater lakes.
Adding particles to liquids to make currents visible is a common practice in the study of fluid mechanics, one that was adopted and perfected by artist Paul Matisse in sculptures he calls Kalliroscopes.
A team involving University of Tennessee, Knoxville, researchers has conducted the first-ever genetic sequencing of a harmful algal bloom (HAB) species, cracking the genome of the micro-organism responsible for the Eastern Seaboard's notorious brown tides.
Warming seas, rising levels of atmospheric carbon dioxide and other factors such as over-fishing could wipe out the worldâ€™s coral reefs by 2050 unless urgent action is taken to counteract these threats.
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...
