The Glen flow law for glaciers is a common relationship linking stress to strain. At its simplest,
$\Sigma = k\tau^n$
where $\tau$ is stress, $\Sigma$ is strain, and $n$ is roughly 3.
I understand that $k$ depends on temperature and material properties of the ice, and that it can vary over two or three orders of magnitude.
I have been searching the literature to find some example values of $k$ (also called $B$ and $A$) but so far I've had a surprisingly hard time. Is there somewhere that has a compilation of $k$ values from various studies?
