Figure 29. Comparison of alkenone SST from Site 1020 to "interglacial lowland forest" pollen percentages. This represents the sum of sitka spruce, western red cedar, western hemlock, redwood, oak, and fern pollen. It is evident that this aggregate basically responds to SST or they both respond to a common outside factor. However, individual plant groups within the interglacial community respond to much more specific needs (e.g., Sequoia) and have significantly different time series.
