The goal of this research is to improve the observation and assimilation of summer sea ice conditions, using the leading-edge capabilities of satellite synthetic aperture radar (SAR) data, so that stakeholders can make informed and timely decisions when operating in ice-prone waters.
Government, industry, and residents of coastal Arctic communities are often required to delay or suspend marine-based activities during the summer due to a lack of tools for assessing risks associated with transient summer ice conditions, and inadequate safety guidelines. Demands for accurate summer sea ice information are expected to increase as vessel traffic increases, vessel technology improves, climate change causes Arctic transit routes to remain open for longer, and new industrial projects are developed.
Achievements of this project include the development of a research and application strategy for northern sea ice hazard assessments using satellite remote sensing, 5 publications in peer-reviewed literature, and 4 academic conference presentations. This project has resulted in the creation of a network of researchers from five Canadian Universities and two agencies of the Environment and Climate Change Canada department of the Canadian government (Meteorological Service and Canadian Ice Service). Four HQP have been trained through this project and three more recruited. Technology exchange achievements include the trial adoption of published results into Canadian Ice Service operational ice-charting workflows.
This project is one of nine research projects funded through MEOPAR's partnership with Irving Shipbuilding Inc. Read More
