Latest Chemical oceanography Stories
A new technique to remove and store atmospheric carbon dioxide has been demonstrated by scientists. The new technique also generates carbon-negative hydrogen and produces alkalinity, which can be used to offset ocean acidification.
Along with other sea organisms, jellyfish are part of the ocean’s natural carbon recycling process. Jellyfish eat microscopic plankton and consequently ingest broken down carbon dioxide. Dead jellyfish then sink to the bottom of the ocean taking a large amount of carbon with them. This carbon becomes trapped in the deep sea water, allowing room for more carbon dioxide to dissolve into the ocean.
The saltiness of the oceans is being closely monitored from space by both ESA’s SMOS and NASA’s Aquarius missions, but in slightly different ways. By joining forces, researchers are exploiting these complementary missions to benefit climate science even further.
New research claims charcoal created from wildfires does not remain in the soil as previously believed, but is instead transported into the sea by rivers, where it ultimately enters the carbon cycle.
Marine scientists have long understood the detrimental effect of fossil fuel emissions on marine ecosystems.
To study the effects of ocean acidification, ten huge plastic containers called mesocosms are placed in the Gullmar Fjord in Sweden.
A continental-scale chemical survey in the waters of the eastern U.S. and Gulf of Mexico is helping researchers determine how distinct bodies of water will resist changes in acidity.
The salinity level of the world’s rivers, lakes and oceans has been a growing topic in response to global climate change. As NASA’s Aquarius instrument has shown previously, seasonal salinity has been on the rise in oceans all around the world.
Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago.
Phytoplankton are important for the sustainability of the aquatic food web. However, future warming oceans could significantly alter the populations of these important 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...
