The ocean is the major element controlling the long-term stability of the e
arth's climate. It involves a complex pattern of interrelations between its
physical, geological, chemical and biological components: the greater the
complexity and diversity of these links the more robust is the stability of
the system, and the healthier the earth. A set of papers that resulted fro
m communications presented at a workshop held in Las Palmas on November 199
8 emphasises the need for an interdisciplinary approach to the ocean.
