Global Climate Change May Make Our Oceans Stinkier

A research team based at the Lawrence Livermore National Laboratory (LLML), the familiar fragrance of the sea is actually a sulfer-rich gas called dimethyl sulfide, or DMS, that is released by ocean plankton. And, as the team's findings suggest, the production of DMS influenced by local temperatures, which may mean that warmer oceans will be smellier as a result. From the LLML : Using climate simulations with a global ocean biogeochemical model, scientists looked at the impact of present-day (355 parts per million) and future (970 parts per million) concentrations of carbon dioxide in the atmosphere on DMS levels and emissions in the Southern Hemisphere. What they found was quite a surprise: In the future scenario, the average DMS emission to the atmosphere was 150 percent more than current levels in the Southern Ocean. Team members found that sea ice changes and ocean eco...
