The Hudson Bay Integrated Regional Impact Study (IRIS 3)

Location or Study Area: Hudson Bay
Submitted by: Lauren Candlish



ArcticNet’s 41 research projects contribute to four Integrated Regional Impact Studies (IRISes) that each underpin an Integrated Regional Impact Assessment (IRIA). Each of the four IRISes corresponds to one of the main political-physiographic-oceanographic regions of the coastal Canadian Arctic.

Many ArcticNet projects operate across the Canadian Arctic and therefore contribute to several of the four assessments. Along with results of other Arctic studies and assessments, and the expertise of ArcticNet’s partners, the scientific conclusions and recommendations produced by the Network’s projects are compiled in the assessments developed for each region.

The Hudson Bay Complex IRIS has been written to summarize the current knowledge available for the coastal and marine environment of the Complex. This IRIS report incorporates results from scientific studies, traditional knowledge compiled in ‘Voices from the Bay’ (McDonald et al., 1997), the perspectives of Inuit and Cree represented through the IRIS steering committee and input from a variety of stakeholders who contributed to the editorial team. The goal of this document is to provide relevant and practical information for regional decision-makers in an accessible format.
