Line Plot from Scientific Research

Sr/Ca ratios (mmol mol -1) from the aragonite skeletons sampled at continuous ~ 2 yr (0.5 mm) intervals from the years 2012 back to 1700. Specimens were collected from OML depths of 33-91 m offshore Puerto Rico and St Croix. Published 25 lower-resolution sclerosponge Sr/Ca analyses (Ce-96 grey symbols) collected 25 from within the OML.
