CKAN version. Reads in external data, combines with internal datasets and produces Canning River surfer plots

canning_surfR takes a file path to Canning River sonde output 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

CKAN_canning_surfR(path, obac, onic)

Arguments

path: Character string filepath to location of sonde data xlsx workbooks.
obac: Character string ("green", "blue" or "red") indicating oxygenation plant status at site BAC.
onic: Character string ("green", "blue" or "red") indicating oxygenation plant status at site NIC.

Value

A pdf format four panel surfer plot of the Canning River. Saved to a directory called `plots/`.

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.
