immediately adjacent to these plots. More intensive studies were undertaken at College, adjacent 

 to an experimental buried hot pipe. The TAPS-sponsaed research projects are being reported 

 upon elsewhere by those directly involved and do not constitute a formal part of the Tundra Biome 

 Program. However, both approaches, the revegetation studies and the basic ecological studies, 

 stand to gain from their close proximity in time and space. The bioenvironmental subprogram is 

 under the direction of the Biome Deputy Director, George West, and Keith Van Cleve. 



The research was performed under a centrally designed and managed ecosystem prc^ram. At 

 Barrow, aU field projects and participants devoted considerable portions of their time to investi- 

 gating plots and study sites agreed upon under the design discussed in the following sections. 

 In return, central services in the form of data processing, laboratory processing of samples, and 

 automated acquisition of environmental data were provided by the central program wherever feasible. 

 This integration of individual projects in both time and space was carried over into several other 

 related research projects, particularly those concerning stressed ecosystems at Barrow, Cape 

 Simpson, and Prudhoe Bay. The planning and execution of integrated research on this scale are 

 criteria set forth by the U.S. IBP. 



Lists of participating projects and individuals are contained in Table I. Each major section 

 of the remainder of this report has one or more authors and many participants. All participants 

 are listed for each major section. This approach emphasizes cooperation and the interaction be- 

 tween the various subprojects listed in Table I, not only by people but mae importantly by 

 disciplines. Several sections of the report are structured according to the four major ecosystem 

 components: abiotic, producers, consumers and decomposers (microbiology and nutrient cycling).
