Description
A dataset containing ages (Tnew), depth values (D), stable
oxygen isotope values (δ18O) and clumped isotope values
Δ47 of a simulated carbonate record based on environmental
parameters following Case 17 and employing a sampling resolution of
0.1 mm, 0.2 mm, 0.45 mm, 0.75 mm, 1.55 mm
and 3.25 mm.

Case simulating a tropical ecosystem – Slight seasonal change in growth rate
with slower growth in summer and linear growth decrease. Confined temperature
seasonality, relatively strong multi–annual trend. Strong
δ18Ow seasonality, light in summer, multi–annual trend
in antiphase with multi–annual SST (ENSO–style)
