During a year away from studies in 1987-88, Dr. Paul Sanborn developed a successful grant proposal to the Science Council of BC (SCBC) to pursue a postdoctoral project with Dr. Tim Ballard in relation to sulphur-deficient soils in BC and prescribed fire. This project built on an existing broadcast burning study conducted by Macmillan Bloedel Ltd. near Port Alberni on Vancouver Island, led by Bill Beese (later at Vancouver Island University). Dr. Sanborn's work addressed sulphur forms and amounts in the soils at these sites, and the chemical processes influencing sulphur availability in relation to prescribed fire.

Only one part of this work was eventually published:
Sanborn, P.T. and T.M. Ballard. 1991. Combustion losses of sulphur from conifer foliage: Implications of chemical form and soil nitrogen status. Biogeochemistry 12: 129–134. https://doi.org/10.1007/BF00001810

The remainder of the work was documented in this Project Completion Report to SCBC, dated February 28, 1990, and entitled "Effects of Prescribed Fire on Sulphur in Forest Soils".

Thirty-four data files were selected for archival retention. There is some redundancy of content among these, with some formatted for incorporation as tables in the report appendices, and others containing some of the same data, but set up as input files for a statistics program. These account for almost all of the data listed in the Project Completion Report appendices. No glossary of variable names is provided, but these should be identifiable by referring to the Report.

The sequence starts from the base camp at the White River crossing on the Alaska Highway and heads south, to a point just upvalley of the debris-covered terminus (approx. 10-15 km from Alaska border), and turning back north to the landing spot on the Generc River floodplain close to the study site (see Fig. 1 in paper).

Fonds consists of the research and professorial records of Dr. Joselito Arocena, a founding faculty member of UNBC. Arocena was an internationally-recognized soil scientist and UNBC’s first Canada Research Chair. His records demonstrate his accomplishments as an academic and researcher, as well as his many and varied interdisciplinary research endeavours. Also included are selections from Arocena’s extensive photographic slide collection which illustrate his teaching, research projects, and personal interests.

File contains photographs depicting close view of drill bits used in the Cassiar mine. The photos were taken for documentary purposes during an evaluation procedure in which the bits were tested and compared. 32 of the photos are adhered to three reports containing detailed analysis of the condition and function of the drill bits used. Reports were addressed to "E. Komperdo / Assist. Mine Superintendent, Production," and were sent by "Bob Clark / Industrial Engineer" and "E. Isaaks / Engineer Trainee." All of the photos are heavily annotated on verso and recto, often documenting the date, bit number, drilling depth, and notes on general condition.

Photograph depicts dump truck under power lines and tramlines on gravel road. Buckets hang on line, mountains in background.
