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，包括大部分的流域喂养大型北极河流，并预计将经历一些最大的气候变化全球世纪。在过去的几十年里，越来越多的陆地有机物（TOM）从北方河流的出口表明气候引起的这些景观的变化与下游水生和海洋生态系统的影响。该研究计划将重点关注TOM在陆地-水生-海洋界面的转化和命运，以了解气候变化对（1）生态系统功能（碳，营养循环和食物网）和（2）北方流域及其相关沿海环境中的气候-碳反馈的影响。
