Peter Pulsifer is a postdoctoral researcher with the National Snow and Ice Data Center (NSIDC), University of Colorado at Boulder where he helps to lead the Exchange for Local Observations and Knowledge of the Arctic project (ELOKA, http://eloka-arctic.org). His research addresses questions related to the use of computer-based forms of geographic information representation with a particular focus on developing theory, methods and tools that inform and support system interoperability: a property that refers to the ability of a entity or system to readily share information and/or operations for a particular purpose. As an applied researcher, Dr. Pulsifer has focused on theory and practice in the context of polar information management. More recently, he has worked with members of arctic communities to facilitate the sharing of local observations and traditional knowledge. This work builds on previous research focused on the needs of small communities. Before coming to NSIDC, Peter was a doctoral candidate and postdoctoral fellow working under Prof. Fraser Taylor at the Geomatics and Cartographic Research Centre, Carleton University. During his doctoral studies he was the lead researcher for The Cybercartographic Atlas of Antarctica Project (CAAP), a research effort developed under the Cybercartography and the New Economy Project and through various International Polar Year initiatives. CAAP aimed to develop an on-line atlas portraying, exploring and communicating the complexities of the Antarctic continent for education, research and policy purposes and is built on a spatial data infrastructure model. He then led the data and knowledge management aspects of the federally funded IPY Inuit Sea Ice Use and Occupancy Project (http://gcrc.carleton.ca/isiuop/). Since 2002, Dr. Pulsifer has been an active member of what is now the SCAR Standing Committee on Antarctic Geographic Information where he has contributed to the conceptualization and development of The Antarctic Spatial Data Infrastructure. In 2003, he became the Canadian representative to what is now the Standing Committee on Antarctic Data Management. This role included contributions to the development of the data policy adopted by the International Polar Year ICSU-WMO Joint Committee. He participated in the IPY Data and Information Service (Project Proposal 49). Currently, Peter is contributing to the development of the Sustaining Arctic Observing Networks program and the establishment of the recently created Inuit Qaujisarvingat: The Inuit Knowledge Centre where he is a visiting research fellow.
