Trans. : No Distribution : 1957-1958 Refernce Levl: All heights have been referred to the station tide staff zero which is linked to fixed bench marks Comment : The daily and monthly means reveal no apparent changes in the reference level. Timing accuracy was extremely poor, no better than +/- 30 minutes. This series is distinguished from Fanning-B because the data have not been linked to a common datum.
