Sean Lynch


Sean Lynch is a former BHAP Master's student who graduated in June 2013. Sean joined the project in 2011, aiding in the first field season excavation at the Hamanaka 2 site on Rebun Island. Sean returned to Hokkaido in 2012 for this MA research, and in 2013 as a teaching assistant for the MacEwan University archaeological field school on Rebun Island.

Sean worked with Dr. Weber in the Department of Anthropology, University of Alberta. For his Master's, Sean conducted an analysis of obsidian artifacts collected from a Middle Jomon and two Okhotsk period sites on Rebun Island, using portable X-ray fluorescence (pXRF). The results of his thesis suggest that changes in obsidian resource use on Rebun Island are directly tied to cultural change in Hokkaido.

Upon graduation, Sean entered the field of cultural resource management. Sean is currently a permit holding archaeologist at CH2M in Calgary, Alberta. As a permit holder, he is responsible for the implementation of archaeological impact assessments in western Canada. His duties include on-the-ground management of field crews, and the writing of concise reports which reconcile the preservation of archaeological materials and the development of natural resources.

In his spare time, Sean sits on the Board of Directors for the Archaeological Society of Alberta (ASA) - Calgary Centre. He is also the instructor for the ASA Strathcona Centre's annual flintknapping and stone tools workshop.
