| Research Abstract |
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.
