## 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.

### Usage

    data(sealevel)

### Author(s)

Dan Kelley

### 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.
