该项目将检查最近在白令海发生的重大生物变化的影响。曾经以硅藻为主的白令海已经变成了以球石藻为主的海洋。浮游植物丰度的巨大变化有许多后果,其中最重要的是球石藻会释放二甲硫化物(DMS)和二甲亚砜(DMSO)气体。DMS和DMSO是温室气体,在北极引入这些气体可能导致该地区变暖加剧,并对北极以外地区产生伴随效应。
英文摘要
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.
