Oyster_Volumes: Formula that calculates volume of the shell through time

In shelltrace: Bivalve Growth and Trace Element Accumulation Model

Description

Formula that calculates the volume of the bivalve shell during the time of deposition of each sub-increment. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

Oyster_Volumes(subincr_matrix, Z_mat, IncG, Xstep = 0.1)

Arguments

subincr_matrix	Data frame that contains characteristics of every sub-increment
Z_mat	Matrix of Z-values for each X-value and each sub-increment
IncG	Matrix of X- and Y-coordinates of all interpolated sub-increments
Xstep	Step value in X-direction for the interpolation of sub-increments

Details

Volume is calculated for each sub-increment and each X-value based on cross sections perpendicular to the XY-plane. Area of the shell in this cross section is calculated by constructing a circle section through the intercept with the base ellipse and the top of the shell sub-increment. See paper de Winter, GMD (in review) for details and illustrations

Value

A list of two data frames:

subincr_matrix	Updated data frame that contains characteristics of every sub-increment with modelled shell volumes added to the matrix
IncGAnet	Matrix of areas of cross sections in YZ-directions sorted by X-values and by sub-increment
