(Credit: SECORE International / Valérie Chamberland) Researchers with the nonprofit SECORE International have developed a new technique for planting coral. The method could enable reef restoration efforts at larger scales. (From UPI.com/ By Brooks Hays) -- Currently, the process of replanting reefs is labor-intensive. Divers plant coral larvae or coral fragments individually. [...]
(Credit: Jay Johnson/ IDDO) There's a new way to measure the average temperature of the ocean thanks to researchers at Scripps Institution of Oceanography at the University of California San Diego. In an article published in the Jan. 4, 2018, issue of the journal Nature, geoscientist Jeff Severinghaus and colleagues at Scripps Oceanography [...]
(Credit: Arcadio Castillo/ Smithsonian) New research has found that in the past 50 years, the amount of ocean areas with zero oxygen has gone up more than fourfold. Low-oxygen sites, as they are called, are regions where water has lost its usual oxygen levels. In coastal water bodies, low-oxygen sites have increased 10-fold [...]
As climate change continues to grip the Arctic—causing the oceans to rise, permafrost to thaw and sea ice to melt—scientists believe they've discovered an unexpected consequence of the shifting landscape. Changes along the coastline are altering the composition of the Arctic Ocean, in ways that could fundamentally transform the local food chain. (From Scientific [...]
(Credit: Olive Ridley Project) Hundreds of marine turtles die every year after becoming entangled in rubbish in the oceans and on beaches, including plastic ‘six pack’ holders and discarded fishing gear. The rise in plastic refuse in the ocean and on beaches is killing turtles of all species, with a disproportionate impact on [...]
A concept image of the REV. (Credit: Nina Jensen) In February, construction will begin on a research and expedition vessel like no other. Nina Jensen, the new chief executive of the company behind the ship, hopes that it will be a “floating think tank” that will change the conversation about ocean health. (From [...]
The world uses 1 billion unrecyclable plastic straws a day – 500 million in the United States – an untold number of which end up in the ocean, polluting the water and coastlines and posing a deadly threat to sea turtles and other marine animals. The Lonely Whale Foundation’s “Strawless in Seattle” campaign resulted in the elimination of 2.3 million disposable plastic straws in the month of September in that city.
Conservation of dwindling fish stocks is being severely hampered by poor controls on global trade, according to research published today (Monday, October 9, 2017) in Scientific Reports. The study carried out by the Ecosystems and Environment Research Centre at the University of Salford looked at global production and trade statistics of the popular 'snapper' fishes and uncovered wide inconsistencies in records meant that the officially reported snapper trade may be underestimated by more than 70%.
An FAO study finds that more than 100 commercial seafood species ingest microplastic, which can be contaminated with toxins. More worrying are the unknown health effects of even smaller nanoplastics. There’s an estimated 51 trillion pieces of plastic in the ocean, most of it broken up into bits smaller than the nail on your pinkie finger. Marine animals eat this plastic when they mistake it for fish eggs, plankton and algae.
Environmental monitoring is an expensive and time-consuming endeavor. One solution: Tap data stored in tweets and Instagram photos to track the health of coral reefs and other marine ecosystems. Social media platforms such as Twitter and Instagram could be a rich source of free information for scientists tasked with monitoring the health of coral reefs and other environmental assets, our new research suggests.
For the first time ever, scientists successfully performed health assessments, including collecting blood and biological samples, taking measurements and attaching satellite tracking tags, to a population of wild whale sharks -- the world's largest fish, classified as "endangered" since 2016. The research advancement, which occurred in Indonesia's remote Cendrawasih Bay, has significant implications for unlocking the mysteries surrounding the overall health of whale sharks -- including the potential impacts of tourism on their health. These details can better inform future conservation policies to protect and encourage their population recovery.
Anchovies are known more as a pickled pizza topping than for their crucial place in the marine food chain. Now scientists have confirmed a disturbing new behavior by these tiny forage fish that could have larger implications for human health: anchovies are eating tiny pieces of ocean plastic, and because they, in turn, are eaten by larger fish, the toxins in those microplastics could be transferred to fish consumed by humans.
