THE ZERO-ORDER MODEL REVISITED - SCHINDLER,PAUL INFLUENCE ON THE DEVELOPMENT OF TRACE-METAL SCAVENGING MODELS

In 1975 Paul Schindler produced the first oceanic trace metal scavengi ng model to explicitly include the role of surface chemistry as a cont rol on trace metal water column residence times. The eighteen years th at have elapsed since the publication of Schindler's seminal paper hav e seen the development of a variety of oceanic scavenging models; yet, the fundamental insight of his ''Zero-order Model'' remains the bench mark. This paper describes the role of Paul Schindler's work on surfac e chemistry in providing a framework for the current generation of tra ce element scavenging models.
