NSDSS Final Workshop - Agenda
• Introductions
1:00 – 1:45 Project Overview and Tool Functionality
1:45 – 2:30 Case Study #1 – White Hills Ice Road
2:30 – 2:45 Coffee Break

4:00 End
Ice Roads are Critical for Resource Exploration in the
Arctic…
• Relatively Inexpensive• Relatively Reliable• Require Little Remediation
Distribution of NorthSlope Lakes
Question:
How can we do a better job of Planning, Permitting, and Communicating Information about Ice Roads on Alaska’s North Slope?
Answer:
The North Slope Decision Support System

NSDSS.net
• MS Silverlight-based web application
• Enables exploration of data, analysis, and publication of findings
• Data stored in statewide cyber infrastructure, and is accessed directly through the web portal through web services
• Map-based application containing four modules that interact with map:
• Data Exploration
• Data Publishing
• Environmental Analysis
• Ice Road Planning
An example of how it Works?

NSDSS Web Tool: Data Publishing
• Add your own data• Point-based• Meteorological Data• Hydrologic Data• Any Data Can be published• Copy and Paste from Excel• Upload to Publish Database• Can be used by others in their analysis
NSDSS Web Tool: Ice Road Planning• Ice Road Planning
• Planning Level Assessment to Determine Potential Ice Road Routes based on:
• Cost• Length• Construction Time• Water Haul Distance• Grade• Water Availability• Environmental Impact
• Advanced Analyses:• Find best place to start
from along road• Landscape Iceroad
Suitability Analysis
NSDSS Web Tool: Environmental Analysis• Used to Assess Environmental Impact and Risk
• Lake Water Budget Analysis• Potential impact to lake water supply given uncertain weather• Takes into account fish presence and regulatory requirement
95% of models predict this much water will be available
5% of models predict this much water will be available
Water Required to build road
Because min level for blue line is higher than 55M gal, shows that 50% of models agree that there will be sufficient water, even in dry years.
50% of models predict this much water will be available
Because red line crosses 55M gal at 65%, shows that 5% of models predict there will be a 65% chance of insufficient water.
NSDSS Web Tool: Environmental Analysis
• Used to Assess Environmental Impact and Risk• Lake Dissolved Oxygen Analysis
• Potential impact to lake water quality given uncertain weather• Takes into account impact of thickening ice and extraction of water’s impact to
total liquid lake volume and resulting DO level.
