sealevelHalifax: Sea-level data set, from Halifax Harbour

Description

This sample sea-level dataset is the 2003 record from Halifax Harbour in Nova Scotia, Canada. Note that Hurricane Juan hit Halifax a half hour before midnight on September 28th of 2003, causing a strong storm surge; see example at plot.sealevel. For reasons that are not mentioned on the data archive website, the record ends on the 8th of October.

data(sealevelHalifax)
