bc_stock()

Description

Estimate the stock of an element contained given its concentration along a sediment core.

Usage

bc_stocks(
  sample_data,
  core_id,
  sample_depth,
  element_concentration,
  maximum_depth,
  method = NULL,
  section_height = NULL,
  diagnostic_plot = FALSE
)

Arguments

sample_data	Sediment sample properties, after calculating elemental concentration and correcting compaction
core_id	Name of for core the identifier. Should be a string
sample_depth	Name of variable for the depth at which samples were taken
element_concentration	Name of the variable for the concentration of the element whose stock is being estimated
maximum_depth	Depth to which to estimate the stock.
method	Method used to estimate the stock, one of "rectangle" or "trapezoid"
diagnostic_plot	Should a plot of how the stock was estimated be shown? FALSE (default) or TRUE
section_start	(Optional, only for "rectangle" method) Depth at which the core section represented by each sample begins
section_end	(Optional, only for "rectangle" method) Depth at which the core section represented by each sample ends

Details

Calculate elemental stocks:

1. Trapezoid rule (Martins, M. et al 2021)

2. Rectangle rule (Howard, J. et al 2014)

• User provides start and end of sections represented by samples

• Heights of sections are automatically estimated 3.(optional) - Plots how the stock is being estimated, with a special draw towards any sections that have to be extrapolated
