“…The site is about 12 km south of the Churchill Northern Studies Center, approximately 23 km east of the town of Churchill (Figure 1). The study area is underlain by continuous permafrost, where the active layer can be over 1.5 m deep (Brown, 1970; Hanis et al., 2013). The Churchill fen (CF) features microforms dominated by sedge lawns, hummocks and hollows, which have up to 0.4 m of peat over carbonate‐rich glaciomarine sediments (Hanis et al., 2013, 2015; Raddatz et al., 2009; Rouse et al., 2002).…”

Northern peatlands have been a persistent net sink of atmospheric carbon (C) due to the greater rates of gross primary production (GPP) compared to ecosystem respiration (ER). Global warming has raised concerns about the C sink strength of northern environments. In the vast peatlands of the Hudson Bay Lowlands (HBL) region of Canada, warming‐induced changes in sea ice dynamics over the Bay have altered its advective influence on the adjacent lowlands. Despite our knowledge of the short‐term C exchange in these peatlands, there remain uncertainties in the long‐term combined response of GPP and ER to climate change. In this study, the satellite‐data‐driven Vegetation Photosynthesis and Respiration Model was employed to investigate the response of peatland GPP, ER, and net ecosystem exchange to temperature and moisture changes. The results show contrasting net CO2 exchange at the two peatland sites over the last 20 years, with the fen acting as a net C source (+24 g C m−2) to the atmosphere and the bog serving as a net C sink (−130 g C m−2). There is ample evidence that a warmer and wetter climate enhanced GPP more than ER, while cooler temperatures weakened the peatland net C sink, regardless of the moisture conditions. Additionally, the advective influence of Hudson Bay on the lowlands produced markedly different C dynamics between offshore and onshore winds, with higher respiration rates (12%–26%) during offshore winds. We discuss the implications for peatland C balance under more frequent onshore winds in the region.

A Just Allotment of Memory: Witnessing First Nations Testimony in Isabelle Knockwood’s Out of the Depths

Isabelle Knockwood’s memoir, Out of the Depths: The Experiences of Mi’kmaw Children at the Indian Residential School at Shubenacadie, Nova Scotia, documents the testimony of survivors, educates non-Aboriginal readers, and reconnects the Mi’kmaw reader to traditional ways of knowing. This essay reconsiders the reception of Out of the Depths by contrasting scepticism towards historical representation with the objectives of survivors to offer testimony and document First Nations experience. In contrast to the Canadian government’s efforts to put the past behind us, the essay advocates the memoir as a model for understanding the living legacy of residential schools.
