Oyster_incr_area {shelltrace}

Area between shell increments

Description

Calculates the area between this shell increment and the previous increment and the cumulative shell cross section area at the moment of deposition of the current increment and adds these to the previously created increment matrix. de Winter, N. J. (2017) <doi:10.5194/gmd-2017-137>

Usage

Oyster_incr_area(cross_section, incr_matrix)

Arguments

cross_section

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

incr_matrix

Matrix containing ages and calibrated ages for each shell increment

Details

Areas between shell increments are calculated by iterating through increments in X-direction (dx) and adding differences in Y-values between increments

Value

incr_matrix

Matrix containing ages and calibrated ages for each shell increment
