Latest Biological oceanography Stories
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.
Researchers studying the origin of Earthâ€™s first breathable atmosphere have zeroed in on the major role played by some very unassuming creatures: plankton.
For the first time, researchers have sequenced the genome of a harmful algal bloom species.
A panel of scientists speaking today at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled new research and models demonstrating how climate change could increase exposure and risk of human illness originating from ocean, coastal and Great Lakes ecosystems, with some studies projecting impacts to be felt within 30 years.
US scientists on Saturday said climate change could increase exposure to water-borne diseases originating in the worldâ€™s oceans, lakes and coastal ecosystems, adding that the impact will most likely be felt within the next 30 years, and as early as the next 10 years.
Blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants, and human health.
Scientists are reporting for the first time that previously unrecognized substances released by algae blooms have the potential to act as endocrine disruptors, which can interfere with the normal activity of reproductive hormones.
University of Tennessee, Knoxville, researchers have found that blue-green algae may be responsible for producing an estrogen-like compound in the environment which could disrupt the normal activity of reproductive hormones and adversely affect fish, plants and human health.
Our growing reliance on coastal waters for food, trade and tourism means that these delicate ecosystems need to be more closely monitored to guarantee their future sustainability.
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...
