High concentrations of brominated halocarbons(CH_3Br, CH_2Br_2, CHBr_3) were found in the mixed water region of the northwest Pacific(42-44°N, 145-160°E). Obvious concentration maximum of the halocarbons were found in the subsurface layer of the southern mixed water(30°N), while the uniform vertical distributions were found in the subarctic water(45°N) from surface to subsurface layer. The horizontal-vertical distribution of brominated halocarbons would be determined from mixed layer formation process, air-sea gas exchange, and phytoplankton production of halocarbons.

在西北太平洋混合水区(42-44°N，145-160°E)，溴代卤代烃(CH3Br2，CHBr3)浓度较高。南方混合水(30°N)次表层卤代烃浓度最高，而亚北极(45°N)次表层卤代烃垂直分布较为均匀。卤代碳化物的水平和垂直分布取决于混合层的形成过程、海-气交换和浮游植物的生产。
