Observed variations in the strontium concentration of sea water

Differences in the Trace Element Deposition in Otoliths Between Marine- and Freshwater-resident Japanese Eels, Anguilla japonica, as Determined by Laser Ablation ICPMS

“…The Sr concentration in seawater is relatively constant at approximately 8 mg/l throughout the world's oceans, which is higher than that in freshwater (0.02 -0.11 mg/l) (Angino et al 1966, Rosenthal et al 1970, Rosenthal 1981. The otolith Sr:Ca ratios found in the present study are consistent with the migration patterns of sea and river eels.…”

“…Following Fujikura et al (2003) and Riascos et al (2007) strontium chloride concentrations were used for the staining experiment 30, 120 and 360 times the strontium concentration of natural seawater of the South Atlantic Ocean (8.8 mg l − 1 on average: Mackenzie, 1964;Angino et al, 1966;de Villiers, 1999). For each treatment 15 randomly assigned wedge clams were available, which were pre-conditioned for two weeks, covering the full range of apSL.…”

Migrations in an extreme northern population of Arctic charr Salvelinus alpinus:insights from otolith microchemistry

“…Strontium is found in low concentrations in freshwater (0.07 ppm) compared to seawater (8 ppm) (Angino et al 1966, Mackenzie & Garrels 1966, Rosenthal 1981, Bowen 1988. Any movement of individual charr between these 2 environments should be reflected in a change of the Sr/Ca ratio in their otoliths.…”
