Oyster_Volumes function

Formula that calculates volume of the shell through time

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

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

Returns

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
