Oyster_Shell_height function

Formula that calculates shell height through time

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

Oyster_Shell_height(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 height is calculated via the Pythagorean Theorem using the X- and Y-coordinates of both ends of the shell increment with extreme X-values

Returns

• 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
