GEOGRAPHIC REGION: Antarctica PERIOD OF RECORD: 418-2 KYrBP DESCRIPTION: Ruddiman and Raymo (2003) Methane-Based Time Scale for Vostok Ice The CH4 time scale originally published by Ruddiman and Raymo [2003] incorrectly specified an age of zero years at a depth of 149.2 meters, the level of the uppermost methane analysis in the Vostok ice-core sequence. The age for this depth should instead be placed at 2.35 ka, as used by Petit et al. [1999]. The ages of all ice-core levels interpolated between this uppermost control and the first methane maximum at 321.2 meters (at 11,000 years ago) are increased accordingly. All ages from 11,000 through 344,000 years ago are those specified in Ruddiman and Raymo [2003]. Ages younger than 2.35 ka are extrapolated upward from our top two control points. ABSTRACT: 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. The immediate basis for tuning CH4 to mid-July insolation is the coincident timing of the most recent (pre-anthropogenic) CH4 maximum at 11,000-10,500 calendar years ago and the most recent July 30°N insolation maximum (all ages in this paper are in calendar years unless specified as 14C years). The resulting CH4 gas time scale diverges by as much as 15,000 years from the GT4 gas time scale (Petit et al., Nature 399 (1999) 429) prior to 250,000 years ago, but it matches fairly closely a time scale derived by tuning ice-core 18Oatm to a lagged insolation signal (Shackleton, Science 289 (2000) 1897). Most offsets between the CH4 and 18Oatm time scales can be explained by assuming that tropical monsoons and ice sheets alternate in controlling the phase of the 18Oatm signal. The CH4 time scale provides an estimate of the timing of the Vostok CO2 signal against SPECMAP marine 18O, often used as an index of global ice volume. On the CH4 time scale, all CO2 responses are highly coherent with SPECMAP 18O at the orbital periods. CO2 leads 18O by 5000 years at 100,000 years (eccentricity), but the two signals are nearly in-phase at 41,000 years (obliquity) and 23,000 years (precession). The actual phasing between CO2 and ice volume is difficult to infer because of likely SST overprints on the SPECMAP 18O signal. CO2 could lead, or be in phase with, ice volume, but is unlikely to lag behind the ice response. DATA: 1.
