CRATER EXPLORATION ACQUAINTANCES

CRATER EXPLORATION ACQUAINTANCES

Dr. Michael R. Dence and yours truly at a 2012 Sigma Xi Companions in Research meeting, Ottawa. Dr. Dence was prime on impact crater research within the Canadian Shield, 1961-81. He was one of the few indiviuals responsible for transforming terrestrial impact crater research into a respectable and scientific discipline of planetary science.
Dr. Ian Halliday and yours truly, Ottawa 2012. Dr. Halliday was a pioneer on impact crater research authoring several papers on the subject. His field research provided evidence in support of a meteoritic origin for West Hawk Lake, Manitoba, Canada.
Dr. Christopher Herd and yours truly at the 2012 RASC GA in Edmonton. Dr. Herd is Associate Professor, Department of Earth and Atmospheric Sciences at the University of Alberta. He was prime in the confirmation of the Whitecourt Crater as an impact structure. He has published papers regarding astromaterials and their significance.
Yours truly with Blyth Robertson. We are standing in front of a desiccation structure (fosilized creek). Dr. Blyth Robertson is Emeritus Scientist with the Geological Survey of Canada. Of the 37 years that he spent with Natural Resources Canada, Dr. Robertson spent 20 years researching impact craters in Canada and worldwide. In the 1970’s Dr. Robertson was instrumental in confirming the impact nature of a large site in northern Canada known as the Haughton Crater.
Yours truly with fellow crater explorer, Dr. Gordon Osinski at the 2016 RASC Ottawa Centre Annual Dinner. Dr. Osinski’s research interests are diverse and interdisciplinary in nature. His work synthesizes field, remote sensing, and laboratory observations with a range of geochemical data. His current research falls into three main areas: planetary geology, astrobiology, and economic geology. Meteorite impact craters provide a common cross-cutting theme. He approaches planetary geology with the fundamental view that interpretations of other planetary bodies must begin by using the Earth as a reference and fieldwork forms the basis for much of his research. His latest research is on the Tunnunik  Impact Structure.
