The project will examine the effects of a major biological change that has occurred recently in the Bering Sea. Once a diatom-dominated ocean, the Bering Sea has changed to a coccolithophore-dominated ocean. The dramatic change in phytoplankton abundance has many ramifications, not the least of which is that coccolithophores emit the gases Dimethylsulfide (DMS) and dimethylsulfoxide (DMSO). DMS and DMSO are greenhouse gases and the introduction of these gases in the Arctic could lead to enhanced warming of the region and concomitant effects beyond the Arctic.

该项目将研究最近在白令海发生的重大生物变化的影响。 白令海曾经是一个以硅藻为主的海洋，现在已经变成了一个以颗石藻为主的海洋。 浮游植物丰度的巨大变化有许多影响，其中最重要的是颗石藻释放出二甲基硫醚（DMS）和二甲亚砜（DMSO）气体。 二甲硫醚和二甲基亚砜是温室气体，在北极引入这些气体可能导致该区域升温加剧，并对北极以外地区产生连带影响。
