400ka-year CH4 data from Vostok core
CTR :271
Key words Vostok core; over the past 400ka; CH4
Relevant data Ruddiman, W.F. and M.E. Raymo. 2003. A methane-based time scale for Vostok ice. Quaternary Science Reviews, Volume 22, Issues 2-4, February 2003, Pages 141-155.
Data shows that
Tuning the Vostok methane signal to mid-July 30°N insolation yields a new ice-core gas time scale. This exercise has two rationales: (1) evidence supporting Kutzbach's theory that low-latitude summer insolation in the northern hemisphere controls the strength of tropical monsoons, and (2) interhemispheric CH4 gradients showing that the main control of orbital-scale CH4 variations is tropical (monsoonal) sources.
