Water with salinity less than °/oo oc- curred in the surface layers of stations 16, 17, and 18. The distribution profiles of particulate organic carbon and nitrogen are shown in Fig. 23-9. Partic- ulate organic carbon values higher than 100 MgC/1 were observed at all shelf stations with an increase eastward from station 12 to station 15 in the surface and subsurface layers, but not in the bottom waters. The distribution profile of particulate organic ni- trogen in this area was almost identical to that of particulate organic carbon. C/N values of the partic- ulate matter ranged from to at stations 12 through 16. Values of POC/chl. a ranging from 52 to 248 were observed in particulate matter at stations 12 through 16. These data indicate that the particulate organic matter consists of phytoplanktonic material to a large extent; however, no characteristic features of C/N and POC/chl. a were observed in core waters with low temperatures, as found centered at station 14. Particulate organic carbon and nitrogen were found to be very abundant at station 17 and the Secchi disk depth was only 7 m (Otabe et al. 1977). The particu- late matter of this station had C/N and POC/chl. a values of more than 15 and 700 respectively even in the euphotic zone. These data indicate that the standing stock of particulate matter was much affected by allochthonous materials at this station. Station 18 showed less effect of allochthonous materials on the standing stock of particulate matter than station 17. One of the most characteristic features o
