Abstract : With the application of an ever increasing variety of CFF system designs, and the reports of spatial and seasonal differences in the abundance and composition of marine colloids (e.g. Baskaran et al., 1992; Moran and Buesseler, 1993), it was clear that a careful evaluation of the performance of currently available CFF technologies was needed. To begin this assessment, we conducted an intercomparison study of CFF for the isolation of marine colloids from seawater. Thirteen different groups gathered first at the Woods Hole Oceanographic Institution and later at the National Energy Laboratory of Hawaii to process simultaneously common seawater samples with their CFF systems. The goal of this study was to assess quantitatively whether ultrafiltration systems from different manufacturer's and used under different operating conditions provided results which were reasonably consistent in both nearshore and offshore environments.
