Upwelling replaces surface waters that biological productivity has depleted in nutrients, with subsurface waters rich in nutrients that stimulate new production. It dominates primary productivity in the world's oceans. Much of the world's oceanic upwelling takes place in the coastal waters of major eastern boundary currents off California, Peru, Mauritania and Namibia, where the resultant productivity leads to major fishing grounds. Upwelling also occurs in the open ocean, especially along the equator and beneath the westerly winds in the subarctic Pacific and the Southern Ocean. This study uses an interdisciplinary approach to establish how upwelling systems work, how they vary through time, and whether or not they have a significant influence on the global carbon cycle. An understanding of how these largely wind-driven biogeochemical systems work today, and how they responded to past fluctuations in climate, is essential in predicting how they and their associated living resources may change in the future. This book recommends new strategies for observation, sampling, monitoring, experimentation and modelling as the basis for improving forecasts of the behaviour of upwelling systems.
