This request from @EmiliaJarochowska needs some discussion because there are a number of aspects to decide on. It is a big topic and quite some work to implement this properly.

One could create a special version of this parameter file, not covering single parameter values but ranges of values for some parameters, with some bin size for the sampling. Then every combination of parameters could be mapped onto a single hdf5 file.
Also, a special setup is needed making sure that the runs for all the combinations of parameters are executed consecutively in an automated way.
Or in parallel, on multiple nodes of a cluster. That would be faster, but would require an mpi version of this codebase.

However, one could end up with a ton of hdf5 files, which requires further data reduction and analysis in order to draw any scientific conclusion.

Ideally, instead of a ton of hdf5 files, one might prefer a single multidimensional graph depicting the effect of the parameter variations on the depth profiles of the five fields, i.e. on aragonite and calcite compositions, on the pore water concentrations of the two ions and on the porosity.
Exactly how this graph should be compiled needs some thought.

But perhaps a ton of hdf5 files as output is good enough as a first step.
