Pteropods are Ptough: How one of the ocean’s most fragile creatures may cope with climate change
Climate change, due to the increase in atmospheric carbon dioxide from fossil fuel burning, is arguably the most important issue facing our planet. One of the most detrimental changes already in progress is the shifting pH of the world’s oceans, known as ocean acidification. Although the speed with which the planet is changing does not […]
A regional perspective on ocean acidification
The regional impacts of ocean acidification are unclear. Researchers measured pH in the intertidal waters off the western coast of the United States. Read more to find out if the water pH was consistent along the coast and whether it is higher or lower than the global average pH of 8.1. Victoria TreadawayI am a […]
Stressed-out microbes in an acidifying ocean
The ocean is acidifying in response to carbon dioxide emissions, but we are just beginning to learn how this effects the ocean’s most abundant lifeforms – microbes. Michael GrawI’m a 5th year PhD student at Oregon State University researching the microbial ecology of marine sediments – why do we find microbes where they are in […]
DIY Science: Scientists create a LED photometer that can measure the pH of seawater with an accuracy of 0.01, for under $50
Do you own an aquarium with high-maintenance saltwater fish that are happy within a narrow pH range? Maybe you just got your first Arduino (http://www.arduino.cc/) or Raspberry Pi (http://www.raspberrypi.org/) and you want to set up your own rig but don’t know what to do. Or maybe you are a citizen scientist who wants to do […]
Emissions from International Shipping Vessels Contribute to Ocean Acidification
Ship emissions of sulfur and nitrogen oxides (SOx, NOx) can be deposited and form sulfuric and nitric acid in surface water. Do heavily-trafficked trade routes result in “hotspots” of ocean acidification? Hassellöv and her team show “hotspots” that coincide with areas of heavy shipping traffic and seasonal stratification.
