Oyster_Mass_gain function

Formula that calculates mass increase of bivalve shell with time

Formula that takes the modelled volume of a bivalve shell by sub-increment and calculates mass increase using variable shell density. de Winter, N. J. (2017) doi:10.5194/gmd-2017-137

Oyster_Mass_gain(subincr_matrix, phase_mat, phases)

Arguments

• subincr_matrix: Data frame that contains characteristics of every sub-increment
• phase_mat: Matrix of amounts of pixels of each phase per sub-increment
• phases: Matrix containing colour, density and trace element data of the phases in the XRF phase map

Details

Calculates mass gain from modelled changes in volume based on the shell density

Returns

• subincr_matrix: Updated data frame that contains characteristics of every sub-increment with modelled shell mass calculations added to the matrix
