Ice sheets and glaciers constitute an enormous water storage, currently corresponding to a potential sea level rise of almost 70 meters if all ice was to melt completely. The ice sheets are dynamic components of the global climate system and numerical modeling is a useful tool that can help us understand and predict how the ice sheets develop. The most accurate model available for ice sheets is given by the Stokes equations, but to solve them for a real ice sheet on a relevant time scale would be way too computationally costly. Instead approximations of the Stokes equations are used such as the Shallow Ice Approximation (SIA). The SIA is valid for areas where the aspect ratio, the ice thickness divided by the horizontal extent of the ice, is small. In this project equations for temperature and surface evolution were implemented in a Matlab version of SIA. The model already had algorithms implemented for computation of stresses, velocities and pressures for an ice sheet with fixed geometry and temperature. Implementation of temperature and free surface equations also made the problem time-dependent. The result was evaluated by solving a simple test problem and comparing the solution to a full Stokes solution obtained with the code ElmerIce. The SIA solution was closer to the Stokes solution when the aspect ratio ε and slope α were decreased simultaneously such that ε=arctanα, but a similar improvement was also obtained when only the slope was decreased. The differences between the two solutions were satisfyingly small for both temperature, surface location and velocities for an aspect ratio of ε= 7.8 10−4 and ε=arctanα.

The 1980s witnessed a judicial “rights revolution” in Canada characterized by the Supreme Court of Canada striking down both federal and provincial legislation which violated the rights guaranteed by the 1982 Charter of Rights. The lack of a similar judicial “rights revolution” in the wake of the 1960 Canadian Bill of Rights has largely been attributed to the structural difference between the two instruments with the latter – as a “mere” statute of the federal parliament – providing little more than a canon of construction and (unlike the Charter) not empowering the courts to engage in judicial review of legislation. Yet this view contrasts starkly with how the Bill was portrayed by the Diefenbaker government, which argued that it provided for judicial review and would “prevail” over other federal legislation. Many modern scholars have dismissed the idea that the Bill could prevail over other federal statutes as being incompatible with the doctrine of parliamentary sovereignty. That is, a bill of rights could only prevail over legislation if incorporated into the British North America Act. As such, they argue that the Diefenbaker government could not have intended the Bill of Rights to operate as anything more than a canon of construction. However, such a view ignores the turbulence in constitutional thinking on parliamentary sovereignty in the 1930s through 1960s provoked by the Statute of Westminster. This era produced the doctrine of “self-embracing” sovereignty – in contrast to traditional “Dicey” sovereignty – where parliament could limit itself through “ordinary” legislation. The effective author of the Canadian Bill of Rights, Elmer Driedger, was an adherent of this doctrine as well as an advocate of a “purposive” approach to statutory interpretation. Driedger, thus, drafted the Bill based upon the doctrine of self-embracing sovereignty and believed it would enjoy a “purposive” interpretation by the courts, with the Bill designed to be as effective at guaranteeing rights as the Statute of Westminster was at liberating Canada from Imperial legislation.
