More Intense Summer to Winter Swings in Oceanic Dissolved CO2
Ocean CO2 levels vary depending on the time of year. Landschützer and his colleagues are the first to show that human-emitted CO2 is making these seasonal swings more severe, potentially to the detriment of many marine organisms. Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is […]
What happens to CO2 levels during El Niño?
Thanks to NASA’s new Orbiting Carbon Observatory-2 satellite, we now know when and where CO2 levels change during El Niño, and can pinpoint the culprit of rising CO¬2 levels during El Niño events. Julia DohnerJulia is a PhD student at Scripps Institution of Oceanography in La Jolla, California. Her focus is on biogeochemistry, which, as […]
What can sea level tell us about long-term climate variability in the Atlantic?
Ocean circulation plays a major role in delivering heat to the subpolar North Atlantic and influence long-term changes in sea surface temperatures. A cleaver use of tidal gauge data shows that we are in for a natural transition to cooler temperatures in the North Atlantic with unfavorable consequences for coastal sea level rise along the […]
The results are in: Ecosystems attune to natural temperature changes
Understanding both physics and biology is crucial in identifying the impacts of climate change on marine ecosystems. This meta-analysis on the ecological responses to natural temperature swings provides an overview of the Atlantic biophysical marine system. Hillary ScannellHillary received her MS in oceanography from the University of Maine in 2014 and works in the Ecosystem […]
