                             Level shifts were identified in the series and
                             adjusted as follows:
                                                            value added

                             These adjustments are uncertain to a few cm.
              Comment      : This series is separate from Arrecife-A because
                             of a sharp level shift on 27 Jan 1973 and on 30 Jul
                             1985.  Otherwise, no level shifts are apparent.
