This sea-level dataset is provided with in Appendix 7.2 of Foreman (1977)
and also with the T_TIDE package (Pawlowicz et al., 2002). It results
from measurements made in 1975 at Tuktoyaktuk, Northwest Territories,
Canada.
Source
The data were based on the T_TIDE dataset, which in turn
seems to be based on Appendix 7.2 of Foreman (1977). Minor editing was on
file format, and then the sealevelTuktoyaktuk object was created
using as.sealevel().
Details
The data set contains 1584 points, some of which have NA for sea-level height.
Although Foreman's Appendix 7.2 states that times are in Mountain standard
time, the timezone is set to UTC in the present case, so that the
results will be similar to those he provides in his Appendix 7.3.
Historical note
Until Jan 6, 2018, the time in this dataset had been increased by 7 hours. However, this alteration was removed on this date, to make for simpler comparison of amplitude and phase output with the results obtained by Foreman (1977) and Pawlowicz et al. (2002).
