The fourth International Polar Year (IPY) has provided us with an unprecedented opportunity to conduct a large-scale, fully integrated study of an important part of the Arctic marine system using the concept of "Two Ways of Knowing" as a guiding framework. The success to date of the Circumpolar Flaw lead (CFL) system study is clearly due to the 692 collaborators, from 27 different countries, who conducted this unique and innovative research. We do not conclude this book in any formal way but rather recognize the people who each made key contributions to this grand adventure. We will leave it to history to judge the ultimate conclusions of our efforts.
