This sample sea-level dataset is the 2003 record from Halifax Harbour in Nova Scotia, Canada. For reasons that are not mentioned on the data archive website, the record ends on the 8th of October.
The data were created as
sealevel <- read.oce("490-01-JAN-2003_slev.csv") sealevel <- oce.edit(sealevel, "longitude", -sealevel[["longitude"]], reason="Fix longitude hemisphere")
where the csv file was downloaded from reference 1. Note the correction of longitude sign, which is required because the data file has no indication that this is the western hemisphere.
