Thompson. Total carbon dioxide During the Thompson cruise in 1978, a preliminary investigation of the total carbon dioxide in the water column was undertaken. The vertical distribution at three stations in the PROBES area is shown in Table 22-2. Station 3016 was in the outer frontal area (55°'N, 168°'W), station 3044 (55°'N, 165°'W) in the central domain, and station 3086 (56°'N, 166°'W) in the middle frontal area in a region of high chlorophyll a. All the values found were low compared to the concentration of mM normally found in surface sea water during unproductive periods in this region of the world's ocean (Park et al. 1974). Station 3044 was in an area
