[Gmsh] Anisotropy and refinement

I've been using gmsh for some time now (but very basically), and there
is a couple of things I'd like to have a few hints for, if possible.
First, I want to mesh a glacier. For this, I mesh its bed by hand. I
don't care about its surface, because I am solving a free surface
problem, hence I mesh a bit more than the actual glacier. The shape of
the top of the mesh (I am referring to the part at the top of the
glacier surface) can be whatever, I don't care. However, I'd like to get
an anistropic mesh. How can I do that?
Second, I am doing parallel simulations, and I'd like to refine my mesh
in a certain way. For instance, I'd like to exactly double the amount of
nodes of my mesh. How do you do that with gmsh? There is a command
refine, but it doesn't do that, as far as I have understood.
