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.
An arsenic surprise: How our buried past will catch up with us
Global sea level is expected to rise 0.8 to 1 meter by 2100 and may release arsenic trapped in soil. Researchers investigated how this arsenic release would impact the biogeochemical cycling of coastal water systems as they are inundated with water due to sea level rise.
I’m Gonna Soak Up the Sun: Sunscreen’s Impact on Coral Communities
Sunscreen prevents skin cancer but may also be linked to coral bleaching and harm to coral larvae. Read more to find out what scientists found in corals off the coast of Hong Kong when they sampled for common sunscreen UV protection chemicals.
Time to update the history books: the future of radionuclides in the ocean
Scientists measured three radionuclides (137-cesium, tritium, and radiocarbon) to understand how Fukushima derived radionuclides are distributed in the North Pacific Ocean.
More than cow burps: the many sources of methane
Methane is an important, and often forgotten, greenhouse gas. It comes from a variety of sources including wetlands, rice paddies, and natural gas operations. This article explores methane’s role in our changing climate and investigates some natural and anthropogenic sources.
What can tuna tell us about mercury emissions?
North America’s mercury emissions have declined over the last two decades. Researchers have found a connection between the declining emissions and the mercury level in tuna. Read more to find out how they made this link and what it could mean for the future.
