Oyster_subincr_av_thickness_X function

Formula that calculates average shell thickness through time

Formula that calculates average shell thickness at the moment of deposition of each shell sub-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

Oyster_subincr_av_thickness_X(IncG, subincr_matrix)

Arguments

• IncG: Matrix of X- and Y-coordinates of all interpolated sub-increments
• subincr_matrix: Data frame that contains characteristics of every sub-increment

Details

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

Returns

• subincr_matrix: Revised version of the "incr_matrix" data frame that contains average shell thickness recalculated for every sub-increment
