Cretaceous sedimentary basins in Western and Arctic Canada are the largest hydrocarbon producers in Canada. Sedimentation and paleobiological communities of Creataceous time are linked to a warm Greenhouse climate and commonly high sea levels forming the Western Interior Sea at times connectingthe Boreal and the Tethyan seas. Most work focused on the southern regions where the majority of petroleum wells are drilled. This research addresses the less studied cretaceous basins of Canada's North including the Eagle Plain and Mackenzie Plain located close to the northern entrance way of the Western Interior Sea and compare those with the Arctic islands relfecting paleoenvironments of the Boreal Sea. These are crucial areas to understandCretaceous paleoclimates, response of flora and fauna and the Boreal paleoceanographic influence on the seaway. Intergrated Cretaceous biostratigraphic frameworks will bring together multiple fossil groups in order to refine existing paleogeographic reconstructions and aid any new mapping efforts. Associated detrital zircon studies will enhance assessment of basin sedimentation and tectonic patterns and constrain provenance interpretations. Carbon isotopes studies will for the first time establish the response of these northern seas tooceanic anoxic events that were common throughout the Cretaceous. The identification of reliable pan-Artic biostratigraphic markers will support future hydrocarbon drilling activities. The project delivers an excellent student training component for industry-related, multidisciplinary field and laboratory based research.

加拿大西部和北极的白垩纪沉积盆地是加拿大最大的碳氢化合物生产商。沉积和古生物学群落的斑点时代与温暖的温室气候和通常形成西部内部海平面的高海平面有关，有时会连接北方和Tethyan海。 大多数工作着重于大多数石油井的南部地区。 这项研究介绍了加拿大北部研究较少的白垩纪盆地，包括鹰平原和麦肯齐平原，位于西部北部北部入口处，并将其与北极岛的河流相比，与北方海的古环境相比。 这些是了解纯净古气候，动植物的反应以及北方对海道的北方古环摄影影响的关键领域。 散布的白垩纪生物地层学框架将汇集多个化石组，以完善现有的古地理重建，并帮助任何新的地图工作。 相关的碎屑锆石研究将增强对盆地沉积和构造模式的评估，并限制出处解释。 碳同位素研究将首次建立这些在整个白垩纪很常见的北部海洋白毒缺氧事件的反应。 可靠的泛术生物地层标记的鉴定将支持将来的碳氢化合物钻井活动。该项目为行业相关的多学科领域和基于实验室的研究提供了出色的学生培训部分。
