Reads in external data, combines with internal datasets and produces Canning River surfer plots
Source:R/canning_surfer.R
canning_surfR.Rdcanning_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 png format. The function creates a
directory called `plots/` in the file path to store the png'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.
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.
- SHELL
Logical (TRUE/FALSE) indicating whether to include the Shelley Bridge site.
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.
