Plot corrected speed of sound

## 1. USAGE

plotssp

## 2. DESCRIPTION

This Matlab scripts makes a plot of the speed of sound vs. time. The input file must contain the following columns:

1. Profile time in decimal days
2. Speed of sound

## 3. PARAMETERS

The following parameters must be edited:

ssp_file

  Name of input data file.

plot_title

  Title for plot.

year_base

  Base year used in input file.

const_ssp

  Constant speed of sound used. Since all VM-ADCP encountered until now are not equipped with a CTD,I dont configure the aquisiton software for speed of sound correction as a function of temperature',but use a contsant value. Corrections are carried out during post-processing,together with CTD data. This constant value will be plotted together with the speed of sound.
