+**MITprof** is a Matlab toolbox designed to (1) standardize ocean profile data collections for use with the [MITgcm][] ‘profiles’ and state estimation packages (Forget et al., 2015) and (2) manipulate and analyze [MITprof data sets][] in combination with the [gcmfaces toolbox][] and ocean state estimates such as [ECCO v4 r2][] (Forget et al., 2016). Download directions in [gcmfaces.pdf][] provide users with a set up to demo MITprof capabilities using [MITprof_demo.m][] and [example_MITprof.m][].
