Nain 970/134 RLR(1972) is 14.2m below BM YARD

Documentation added 1997-09-24

1963-88 gauge type=float/stilling well 1989-94 gauge= other pressure type

Documentation added 2010-08-19

There is a gap in the dataset from 1988-2002. However, the RLR factor remains unchanged.

Documentation added 2015-07-27

This year, rather than just sending the latest year of data, the complete dataset has been supplied. This has highlighted some differences in the data. From communications in the correspondence file for 2002 it appears that the Oceans and Fisheries meant to supply revised data for the stations supplied. This did not happen. The complete dataset includes these data revisions. Therefore, the whole dataset has now been re-entered.

Documentation added 2015-07-30

Historic data was included in the above complete dataset. The datum for the period 1963-1988 is currently being queried. Until the Fisheries and Oceans Canada confirm the datum this data has been made Metric. Previously this station was flagged on review this station flag has now been removed.

Documentation added 2017-06-29

Data for 2012-2015 updated for Canadian Atlantic network. The supplier provided a finalised version following a review by the regional office.
