Unfortunately, Worthington?s efforts were devoted to a period of minimum production of this water. In contrast to this minimum period in 1976 (denoted by red curves of temperature and potential density), a period of maximum climatological production occurred in 1964 (blue curves). In both cases, the plot shows the annually averaged properties for both calendar years vs. pressure to reduce eddy noise. Note that the underlying thermocline at pressures of more than 600 decibars is similar in both periods: Changes are not induced from below.[back]
