Latest Chemical oceanography Stories
How is vital oxygen supplied to the tropical ocean? For the first time, oceanographers at GEOMAR Helmholtz Centre for Ocean Research Kiel were able to make quantitative statements regarding this question.
NOAA-supported scientists found a large Gulf of Mexico oxygen-free or hypoxic "dead" zone, but not as large as had been predicted.
The supply of dissolved iron to oceans around continental shelves has been found to be more variable by region than previously believed -- with implications for future climate prediction.
Scientists at the Virginia Institute of Marine Science have completed a 10-year study, providing the first quantitative evidence on a bay-wide scale that the distribution and abundance of "demersal" fishes -- fish species that live and feed near the Bay bottom -- are being impacted by low-oxygen "dead zones."
This year, scientists are expecting a very large “dead zone” in the Gulf of Mexico, according to several NOAA-supported forecast models. Those same models predict a smaller than average hypoxic level in the Chesapeake Bay.
The density of coral skeletons will be reduced by ocean acidification due to rising carbon dioxide levels, according to an international group of scientists led by the University of California, Santa Cruz.
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.
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...
