| contents | A depth transect of deep-sea bamboo corals along the California margin provides evidence that coral strontium to calcium ratios (Sr/Ca[coral]) record seawater Sr/Ca ratios (Sr/Ca[sw]). A calibration was constructed utilizing Sr/Ca[coral] ratios and previously published Pacific Sr/Ca[sw] data (R**2 = 0.53, n = 12, p < 0.01): Sr/Ca[coral] (mmol/mol) = 4.62*Sr/Ca[sw] (mmol/mol) - 36.64. Sr/Ca[sw] is ultimately governed by the remineralization of Sr-containing shells of surface water-derived marine organisms (e.g., Acantharia) at intermediate water depths. California margin Sr/Cacoral records from 792 and 1295 m document fluctuations in Sr/Ca[sw] that appear decadal-scale. These results suggest that Sr/Casw may not be as stable as previously assumed and may be influenced by surface productivity on short timescales. |
