My research group works to determine how the marine environments of Arctic Canada have changed in response to climate change since the last Ice Age (~22,000 years ago) to the present. The focus of this research program, the Northwest Passage (NWP) – the historical route between the Atlantic and Pacific oceans via the shallow channels of the Canadian Arctic Archipelago (CAA) – is a crucial gateway for heat and water transport from the Arctic Ocean to the North Atlantic. This region has been affected by recent climate change, experiencing pronounced shifts such as decreasing seasonal sea-ice cover. Such changes urgently require Canadian stewardship to contribute to issues of growing social and economic importance. As such, my timely research program will generate new knowledge highly relevant to Arctic communities and decision makers in anticipation of expanded NWP use, as further climate change opens up this region for extensive ship traffic.

我的研究小组致力于确定加拿大北极地区的海洋环境如何自上一个冰河时代（约22，000年前）至今因气候变化而发生变化。该研究计划的重点是西北航道（NWP）-大西洋和太平洋之间通过加拿大北极群岛（CAA）浅海峡的历史路线-是从北冰洋到北大西洋的热量和水运输的重要门户。该区域受到最近气候变化的影响，经历了明显的变化，如季节性海冰覆盖面积减少。这些变化迫切需要加拿大的管理，以促进日益重要的社会和经济问题。因此，我及时的研究计划将产生与北极社区和决策者高度相关的新知识，预计NWP的使用将扩大，因为进一步的气候变化将使该地区成为广泛的船舶交通。
