| 英文摘要: | This study aimed to investigate the environmental controls on the oxygen isotope composition of shells of the European abalone, Haliotis tuberculata. Seasonal δ18O profiles from the outer prismatic layer of four abalone shells, collected live in northwest Brittany (France) in 2002 and 2012, were compared to local temperatures and salinities. According to the findings herein, δ18O variations in abalone shells corresponded to seasonal variations, and thus, shell composition represented a reliable tool for aging and growth studies. Seawater temperatures estimated from the abalone collected in 2012 reflected the in situ measured temperatures, but the reconstructed temperatures from shells of the three specimens collected in 2002 deviated from measured temperatures by 2.5°C. This overestimation of temperatures corresponded to a "kinetic effect" related to very high annual abalone growth rates; thus, it could be corrected by applying +0.53% to the δ18Oshell. This methodology was then applied to a fossil (6000calyr BP) collected in the Bay of Biscay. Given the worldwide distribution of both live and fossilized abalones, the results of the present study showed that this genus represents a promising paleoclimatic tool. We analyzed δ18O composition of modern and fossil abalones. δ18O variations corresponded to seasonal temperature variations. Overestimation of temperatures was related to high growth rates. Paleo and actual seawater temperatures can be reconstructed from δ18O of abalones. © 2015 Elsevier B.V.. |
