Downcore variation involved subtle changes in distribution, C22 and C24 covarying and suggesting a similar source, perhaps partially aquatic, with an increase in recent decades perhaps related to indirect fertilization of the lake (Fig. 5a).

Rapid transfer from plant to sediment is likely within the small, steep-sided watershed, suggesting that the leaf wax record would be capable of reconstructing up to decadal resolution variation in leaf wax dD values.

These changes in moisture source have been further linked to SST anomalies (SSTa) in the Kuroshio Extension region of the N Pacific, which exerts steering on atmo- spheric circulation and hence moisture sources to the west coast of N America. ... These positive excursions may be linked to warm Kuroshio Extension SSTa, driv- ing greater amplitude waves in the circulation over the N Pacific entraining subtropical moisture sources but generally associated with drier conditions in coastal southern California. Conversely negative isotopic excursions centered on 300 and 800 yr BP may correspond to more N Pacific moisture flux and wetter conditions in coastal southern California, the former of these perhaps associ- ated with the Little Ice Age. In combination with other proxies recording wet/dry climate regime shifts, the information on mois- ture source from precipitation isotopes may thus be particularly helpful in understanding the dynamical causes of hydroclimate shifts. Warm SST anomaly --> less moisture flux -->more enriched precipitation. "Elevated dD values indi- cate more (sub)tropical moisture sources and/or drier conditions, whereas lower dD values are consistent with N Pacific moisture sources and/or more antecedent precipitation.
