Oyster_Shell_thickness {shelltrace}

Formula that calculates average shell thickness through time

Description

Formula that calculates average shell thickness at the moment of deposition of each shell increment from X- and Y-coordinates of the shell increments and adds the result to the matrix of increment characteristics. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

Oyster_Shell_thickness(cross_section, incr_matrix)

Arguments

incr_matrix

Matrix listing characteristics of each digitized increment

cross_section

Digitized cross section of the shell with shell top, bottom and growth increments relative to a common X-axis

Details

Shell thickness is calculated as the average difference in Y-values between the shell increment and the top of the shell (Increment 0)

Value

incr_matrix

Updated matrix listing characteristics of each digitized increment, shell thickness values are added

A plot of the change in shell thickness with shell age based on the digitized growth increments is produced in a new window
