In Bartesto/monitoR: Functions to aid in reporting on the Swan and Canning Rivers

Description

swan_surfR takes a file path to Swan River sonde outputs and creates a four panel (single column) surfer plot of salinity, dissolved oxygen, chlorophyll a, and temperature in pdf format. The function creates a directory called ‘plots/' in the file path to store the pdf’s. Code expects only 2 excel workbooks for one monitoring run. Note sonde data from EXO models reads depth from the VPos metric. All other sonde models use a variant of a depth metric.

Usage

swan_surfR(path, ovit, ocav)

Arguments

path	Character string filepath to location of sonde data xlsx workbooks.
ovit	Character string ("green", "blue" or "red") indicating oxygenation plant status at site VIT.
ocav	Character string ("green", "blue" or "red") indicating oxygenation plant status at site CAV.

Details

Surfer plots display a cross-section of the river where the metrics of interest have been interpolated between sonde locations. Thin plate spline has been used for the interpolation.

A river "bottom" is displayed which puts the interpolation in context. The river bottom has been derived from a combination of historical maximum depths at sampling locations as well as station points extracted from a "best" navigation line over the latest corporate bathymetry. See project documentation for further details.

Value

Two pdf format four panel surfer plots of the Swan River. One shows the full extent of the monitoring run (river mouth to the just beyond the site POL - Upper Swan Power Lines). The second shows from the Narrows Bridge to site POL. Saved to a directory called 'plots/'.
