Recent Progress and Further Potential: High-resolution Holocene Climate Reconstruction with Coral Reefs in the South China Sea

PAGES NEWS, VOL.13, N°2, AUG. 2005 tion among the Dasuopu core, the Greenland cores, and the Antarctic cores. The Dasuopu values differ by an average of 66 ppbv from the Greenland values and 109 ppbv from the Antarctic values. The average difference between the Greenland and Antarctic records is 44 ppbv in the time interval of 0-1850 AD. The higher methane gradients between the Dasuopu core and the polar region suggest that the lowmiddle latitude acted as the most important methane source in the pre-industrial period.
