| The Lowest Sea Surface Temperatures for Stopping Secretion in Winter and Resuming Growth in Spring Recorded by the Living Pacific Oyster (Crassostrea gigas) Shell in the Bohai Bay |
| Oyster reefs are widely distributed along coastal and estuary areas. The in situ living oyster shell is a good object for studying and reconstructing the climate and environment change. With a living Pacific oyster (Crassostrea gigas) shell collected from the northwest coast of Bohai Bay as the study object and according to the analytical results of stable isotope of O in the continuous growth micro-layers of the shell as well as monthly average sea surface salinity (SSS) and sea surface temperature (SST), the authors obtained the lowest sea surface temperature recorded by the C. gigas shell in winter. In Bohai Bay area, the cease of shell growth of C.gigas lasts for up to 3 months per year from December to March, when the water temperature decreases to 5.5℃. |
