This poster in Cree and English was presented at a climate summit organized by the Mushkegowuk Council (http://www.mushkegowuk.com/) in January 2018.

The Hudson Bay Lowlands (HBL) along the western coast of Hudson Bay is the world’s second largest permafrost peatland complex. Regardless of its relatively low latitude, sea-ice dynamics in Hudson Bay provide the HBL with a sub-arctic climate, allowing for continuous and discontinuous permafrost to be present at lower than normal latitudes. Recently, changing sea-ice dynamics have put the area at high risk for rapid warming, and therefore rapid degradation of permafrost. This poster presents preliminary results concerning the microbial production of CH4 and CO2 during incubations of peat and permafrost samples at two different temperatures.
