Findings by Rosenstiel School researchers have important implications for ocean life
A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science-led study shows that the North Atlantic absorbed 50 percent more man-made carbon dioxide over the last decade, compared to the previous decade. The findings show the impact that the burning of fossil fuels have had on the world's oceans in just 10 years.
To determine the total uptake and storage of carbon dioxide in the North Atlantic over the last several decades, researchers analyzed data collected from the same locations, but 10 years apart, to identify changes caused by man-made CO2.
The data were collected during two National Science Foundation-funded international ship-based studies, CLIVAR (Climate Variability CO2 Repeat Hydrography) and GO-SHIP (Global Ocean Ship-Based Hydrographic Investigations Program).
"This study shows the large impact all of us are having on the environment and that our use of fossil fuels isn't only causing the climate to change, but also affects the oceans by decreasing the pH," said Ryan Woosley, a researcher in the UM Rosenstiel School, Department of Ocean Sciences.
The oceans help to slow the growth of human produced CO2 in the atmosphere by absorbing and storing about a quarter of the total carbon dioxide emissions. The North Atlantic is an area of high uptake and storage due to large-scale ocean circulations.
The uptake of CO2 has many impacts on ocean-dwelling organisms by decreasing the pH. The findings have important implications for marine organisms, such as corals and mollusks, which require a certain pH level in the surrounding water to build their calcium carbonate-based shells and exoskeletons.
The researchers hope to return in another 10 years to determine if the increase in carbon uptake continues, or if, as many fear, it will decrease as a result of slowing thermohaline circulation.
The study, titled "Rapid Anthropogenic Changes in CO2 and pH in the Atlantic Ocean: 2003-2014" was published in the journal Global Biogeochemical Cycles. The study's authors include: Woosley and Frank J. Millero of the UM Rosenstiel School; and Rik Wanninkhof of NOAA's Atlantic Oceanographic and Meteorological Laboratory. The study was funded by the National Science Foundation through grant #OCE0752972. The study can be accessed at http://onlinelibrary.

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, the Italian Space Agency (ASI), and the Instituto Geofisico--Escuela Politecnica Nacional (IGEPN) of Ecuador, showed an increasing volcanic danger on Cotopaxi in Ecuador using a powerful technique known as Interferometric Synthetic Aperture Radar (InSAR).
The Andes region in which Cotopaxi volcano is located is known to contain some of the world's most serious volcanic hazard. A mid- to large-size eruption has...
