cerning tundra structure and function. 



Along with the many authors and contributors to this volume, many 

 other investigators, undergraduates, graduate students, technicians, and 

 support staff participated in the Tundra Biome program. Appendix 1 

 contains a complete list of all Biome participants and the affiliation of 

 the principal investigators. In addition, a considerable number of inter- 

 national Tundra Biome members participated in various U.S. activities; 

 these individuals are also listed in Appendix 1. 



As this book goes to press, we are saddened to report that the Naval 

 Arctic Research Laboratory has closed its doors to the support of scien- 

 tific research. This results from the lack of funds to operate the Labora- 

 tory. Those of us who have literally spent hundreds of field seasons con- 

 ducting field and laboratory research in the Barrow environs hope that 

 the closure of this scientific facility on the shores of the Arctic Ocean is a 

 temporary action and that future generations of scientists will enjoy the 

 logistic opportunities we have been privileged to experience over the past 

 several decades.
