ctdRaw {oce} | R Documentation

## Seawater CTD profile, without trimming of extraneous data

### Description

This is sample CTD profile provided for testing. It includes not just the (useful) portion of the dataset during which the instrument was being lowered, but also data from the upcast and from time spent near the surface. Spikes are also clearly evident in the pressure record. With such real-world wrinkles, this dataset provides a good example of data that need trimming with `ctdTrim`.

### Usage

    data(ctdRaw)

### Author(s)

Dan Kelley

### Source

The data were acquired near the centre of the Bedford Basin of the Halifax Harbour, during an October 2003 field trip of Dalhousie University's Oceanography 4120/5120 class. The original `.cnv` data file had temperature in the IPTS-68 scale, but this was converted to the more modern scale using `T90fromT68`.

### See Also

A similar dataset, but trimmed to the downcast, is provided as `ctd`. The documentation for `ctd-class` explains the structure of `ctd` objects, and also outlines the other functions dealing with them.
