A Blueprint for Alaska’s Broadband FuturePlanning for Alaska’s broadband future is imperative because the state lags in adequate statewide infrastructure. In fact, a 2012 “State Broadband Index” developed by TechNet, an advocacy group comprised of innovators and technology leaders, ranked Alaska 49th of all 50 states in broadband adoption, network quality, and economic structure.communication infrastructure
About the GIPL Permafrost Dynamics Model

The Geophysical Institute Permafrost Lab (GIPL) model was developed specifically to assess the effect of a changing climate on permafrost. The GIPL 1.0 model is a quasi-transitional, spatially distributed, equilibrium model for calculating the active layer thickness and mean annual ground temperature.

ALFRESCO Model Overview

State-transition type vegetation succession model that focuses on system interactions and feedbacks. User-defined spatial resolution (currently operational at 1 km pixels). User-defined temporal resolution (currently operational on annual time step w/ monthly fire-climate relationship). Pixels are randomly “ignited” and fire “spreads” as a function of climate and vegetation state.

Identifying Indicators of State Change and Forecasting Future Vulnerability in Alaskan Boreal Forest

This research is designed to understand the mechanistic connections among vegetation, the organic soil layer, and permafrost ground stability in Alaskan boreal ecosystems. Understanding these linkages is critical for projecting the impact of climate change on permafrost in ecosystems that are subject to abrupt anthropogenic and natural disturbances (fire) to the organic layer.

IEM Executive Summary

Alaska’s temperatures are rapidly increasing. The resulting changes in temperature, precipitation, permafrost, vegetation, and fire are closely linked. The Integrated Ecosystem Model for Alaska and Northwest Canada (IEM) aims to understand how changes in these processes are linked and how they will affect the broader region.

IEM Fact Sheet

The Integrated Ecosystem Model is designed to help resource managers understand the nature and expected rate of landscape change. Maps and other products generated by the IEM will illustrate how arctic and boreal landscapes are expected to alter due to climate-driven changes to vegetation, disturbance, hydrology, and permafrost.

IEM Final Report

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.

Peonies in a Changing Climate: A Case Study

Peony farming serves as an excellent case study for research on climate change and agriculture in Alaska. Why? Peonies represent a burgeoning niche market, and are a crop that is uniquely lucrative in Alaska for reasons linked directly to our climate. Peonies bloom in Alaska in July, August, and September—later in the year than in other locations—and are available commercially nowhere else in the world during this time.
