This report describes the progress made by the Integrated Ecosystem Model (IEM) for Alaska and Northwest Canada Project for the full duration of the project (September 1, 2011 through August 31, 2016).

The primary goal of this project was to develop the IEM modeling framework to integrate the driving components for and the interactions among disturbance regimes, permafrost dynamics, hydrology, and vegetation succession/migration for Alaska and Northwest Canada.

The major activities of the project include: (1) development and delivery of input data sets, (2) model coupling, (3) evaluation and applications of fire and vegetation dynamics, (4) evaluation and application of ecosystem carbon and energy balance, (5) evaluation and application of regional permafrost dynamics, (6) permafrost infrastructure modeling research, (7) development of a landscape thermokarst modeling capability, and (8) development of wetland modeling capability based on field studies.

Here we briefly describe the key accomplishments for each of the major activities of the project as well as a summary of next steps for each of the major activities.
