Elements of Permafrost Science with Dr. Chris Burn (Carleton University)
This module focuses on the ground thermal regime – the temperatures observed within the ground and how they vary over the year.
In this video, Dr. Chris Burn defines fundamental permafrost terminology, describes the permafrost thermal regime, explains permafrost zones, and shows the distribution of permafrost in Canada.
Summary video |
In this video, Dr. Chris Burn explains the climatic factors affecting permafrost distribution across Canada.
Summary video |
In this video, Dr. Chris Burn describes how thermal properties and fluxes affect permafrost thickness.
Summary video |
In this video, Dr. Chris Burn explores the microclimatic factors that control the spatial variation in ground temperatures and the presence of permafrost in discontinuous permafrost zones.
Summary video |
In this video, Dr. Chris Burn covers parameters that govern the thermal regime of the active layer, including ground ice content, latent heat exchanges, thermal conductivity, and snow cover.
Summary video |
In this video, Dr. Chris Burn explains the relationships between air, ground surface, and permafrost temperatures and the indices that are used to quantify these relationships.
Summary video |
In this video, Dr. Chris Burn describes the mechanics of how heat flows through the ground and how ground temperatures vary throughout the year.
Summary video |
In this video, Dr. Chris Burn shows how the basic principles of heat flow can be used to calculate the depth of aggrading (or degrading) permafrost as a function of time.
Summary video |
In this video, Dr. Chris Burn reiterates key points from module 1.
Summary video |
These materials aim to summarize some of the basic ideas and information you may need to understand the behaviour and sensitivity of permafrost terrain. The videos are organized into 3 modules, where each module contains 8 lectures. For each lecture, there is a short summary video. Full-legnth lectures will be posted soon, so stay tuned!
Module 1: The Ground Thermal Regime
Module 2: Ground Ice Characteristics and Development
Module 3: Permafrost Geoscience
