ctdRaw: 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.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.
