Boreal landscapes cover most of Canada, encompass the majority of the watershed feeding large Arctic rivers, and are predicted to undergo some of the largest climate changes globally this century. Increasing terrestrial organic matter (TOM) export from boreal rivers over the past few decades suggests climate-induced alterations of these landscapes with repercussions for downstream aquatic and marine ecosystems. This research program will focus on the transformation and fate of TOM across the terrestrial-aquatic-marine interface to understand climate change impacts on (1) ecosystem function (carbon, nutrient cycling and food webs) and (2) climate-carbon feedbacks within boreal watersheds and their associated coastal environments.

北方景观覆盖了加拿大的大部分地区，包括了流入北极大河的大部分分水岭，预计本世纪将经历一些全球最大的气候变化。在过去的几十年里，北方河流不断增加的陆地有机质(TOM)出口表明，气候诱导的这些景观发生了变化，对下游的水生和海洋生态系统产生了影响。这项研究计划将重点研究TOM在陆地-水生-海洋界面上的转化和命运，以了解气候变化对(1)生态系统功能(碳、养分循环和食物网)和(2)北方流域及其相关沿海环境中的气候-碳反馈的影响。
