Using data from the latest UHSLC Joint Archive for Sea Level CD data for 2001-2006 has been added to the Cox's Bazaar 'METRIC' dataset. Even with overlapping values the data is not identical to that already held with differences in the order of +-20mm but it was felt the additional data would benefit the dataset.

Documentation added 2013-06-17

The RLR diagram for Cox's Bazaar has been revised.Previously rlrfac adjustments of 4.864m were made 1976-1982 and 1986 onwards and 4.929m for data 1983-1985.However, when the PSMSL data holdings were compared with those from UHSLC anomalies were found. As a result just one adjustment of 4.864m has been applied to the whole dataset.
