| We have generated a record of alkenone sea surface temperatures (SSTs) during the last 28000 years from Core MD97-2146 for the northern South China Sea (SCS). The SST record showed a typical pattern for change in the northern SCS SST. The SST during the LGM was similar to 25 degrees C, this decreased to similar to 24 degrees C to 17 ka, increased to similar to 25.5 degrees C to 14.5 ka, decreased again to similar to 24.5 degrees C to 11.8 ka, increased gradually to similar to 27 degrees C to 6 ka, and then increased more gradually to reach similar to 27.5 degrees C at present. The SST difference (Delta SSTNSCS = SSTMD97-2146 - SSTMD97-2141) between Cores MD97-2146 (the northern SCS; this study) and MD97-2141 (the Sulu Sea; Rosenthal et al. 2003) was used... |
