Salinity dissolution experiment
Bethany King, Dept. of Earth Sciences, University of Cambridge
Experiment was carried out between January and August 2024. Data collection was made in August 2024 at the University of Cambridge.
Spreadsheet 1: Resin_blocks_shell_loss
Salinity Measured as ppt using a handheld salinity meter (HI-98319, Hanna Instruments)
Microstructure As determined by the literature and SEM micrographs
Microstructure_b Common microstructures
Species Genus and species name
Mineralogy Aragonitic or calcitic polymorph
Block_ID Individual blocks were labelled on removal from the tubs
Measurement Max change in depth was measured using one transect across the whole surface shell, in addition to four 2-point measurements made from the centre out
Shell_loss Measured in micrometers
Magnification Magnification of the microscope when measurement was made
Organics Determined by thermogravimetric analysis as proportion of weight
Mg:Ca Ratio of magnesium to calcium in the calcitic microstructures
Crystal size Measured in micrometers on SEM micrographs
Spreadsheet 2: Crystal size
15 measurements of crystal size (measured in micrometers) using ImageJ on SEM micrographs. Average and standard deviations were calculated.
Spreadsheet 3: Organic content
Determined by thermogravimetric analysis as proportion of weight.
