Tritium Time Series from Ocean Station P

Abstract We present time series of tritium (3H) concentrations at varying depths in the water column at Ocean Station P(50°N, 145°W) in the northeast Pacific. Measurements started in the fall of 1974, at the time of the GEOSECS mapping of the North Pacific, and extended through 1982. When combined with the GEOSECS spatial maps, various features of the observed tritium time series suggest that the vertical distribution of tritium (and presumably other conservative tracers) at Station P is determined mainly by advection along isopycnals.
