sealevel: Sea-level data set, from Halifax Harbour
Description
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.source
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 [1]. Note the correction of longitude
sign, which is required because the data file has no indication that
this is the western hemisphere.References
