MRSea and MRSeaPower

MRSea

Marine renewables strategic environmental assessment

Software for fitting one and two dimensional spatially adaptive smoothing splines.  This software was developed for the marine renewables framework but is suitable for most smoothing applications. Information about the package and tutorials can be found on the website.
