Formula that calculates shell height 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>
1 | Oyster_Shell_height(cross_section, incr_matrix)
|
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 |
Shell height is calculated via the Pythagorean Theorem using the X- and Y-coordinates of both ends of the shell increment with extreme X-values
incr_matrix |
Updated matrix listing characteristics of each digitized increment, shell height values as well as the coordinates of both ends of the shell increments are added |
