Objective(s): To create a permafrost hazard/vulnerability map of the community of Whati, NT.

Project Description: The goal of this project is to create a permafrost hazard/vulnerability map of the community of Whati, NT. In addition to the general map, ideal location(s) for future graveyard and residential development will be identified. The three main deliverables outlined in conversations with representatives from Whati are: suitable location(s) for future graveyard development, suitable locations(s) for future residential development and a more general permafrost vulnerability map of the community. The field season in August 2019 will be dedicated to setting up weather stations and microclimate stations in Whati. Consultations with the community about possible locations for the stations will take place in the lead up to the field season as well as final confirmation when the research team arrive in Whati. In order to take in situ measurements used to verify the data the team will use a soil probe and shovel to test the soil/permafrost of the area. Soil samples may be collected in order to derive useful soil characteristics. Vegetation surveys of the sites will be performed by observation while in the field. Photos will be taken as well as GPS points in order to create accurate site descriptions and maps. The following field season will involve replacing broken sensors and equipment as well as downloading the data from the microclimate stations. In addition to station upkeep more in situ data will be recorded. Once again meeting with community members, consultation and a trip out to our sensors with community members will be part of the field season. The permafrost vulnerability mapping will be performed by creating spatially distributed climatological surfaces, soil properties surfaces, permafrost properties surfaces and vegetation cover surfaces. These will all act as inputs to the permafrost model. Existing climate data will be used to inform the understanding of the climate in the region as well as future decision making. In addition to using it as a model input the historic borehole data will be used to create a baseline and to understand the historic soil conditions of the area.
