Abstract:
The data set comprises time series of sea level data from coastal tide
gauges. The data holdings include over 1000 site years of data from
about 200 sites comprising about 10 million records. About 75 per cent
of the data are from some 100 sites around the British Isles - the
remaining data are from coastal sites and islands scattered across the
globe. Data are primarily hourly values. Recording
... periods vary from
one month at some sites to over 50 years in the case of Newlyn, Dover,
Southend, Tilbury and Tower Pier, London. There are three short series
from around the Irish coast which were collected in 1842.
The data set includes data collected via the UK Class A network. Data
from this network of about 40 sites around the coast of the UK are
received weekly via telephone links. The data are carefully quality
controlled by comparison with predictions and examination of
residuals. Incoming data are checked both weekly and monthly and are
added to the databank annually.
A large number of charts (originals and copies) together with
tabulations of data are also available, some of which date back to the
1850s. A more detailed description of these will be available once
they have been systematically catalogued and archived.
