Objectif(s): To understand how permafrost slumping increases the mobilization of organic carbon from land to water, and the effects of this movement on stream communities.

Description du projet: The objective of this study is to understand how permafrost slumping increases the mobilization of organic carbon from land to water, and the effects of this movement on stream communities. The research team will measure the concentration of stream-water organic carbon upstream and downstream of slump sites. The research team will also examine the fate of this carbon by undertaking incubation experiments that measure bacterial uptake and degradation of carbon travelling from slump sites to downstream locations. The research team will collect water samples from upstream and downstream of slump sites. When possible, the team will also collect samples of runoff water directly from the slump sites. Water samples will be filtered in the field using a hand pump. Further analyses, including incubation experiments, will be conducted at the Aurora Research Institute. The research team will not be collecting any biological specimens other than the bacteria that occur naturally in filtered water samples. The research team are happy to give presentations about the research to local schools, or to any other group that would like to receive such a presentation. The team is happy to give any presentations about the research to any community organizations that would like to receive a presentation. Once this research is complete, a poster will be prepared, that can be displayed at the Aurora Research Institute that outlines our findings. The team will also send copies of any publications that result from this research to the Aurora Research Institute library. Finally, the research team plan to hire a local resident to assist with the sampling effort, as in previous years. This will both allow the resident to gain a better knowledge of field sampling techniques, and allow for the team to communicate the purpose of the research and methods for carrying the research out to a member of the local community. The fieldwork for this study will be conducted from July 4, 2014 to September 5, 2014.
