Table S2. Taxa classified as aquatic and lacustrine pollen types in the Global Pollen Database, as used in main Figure 2E. Table S3. Peat bog sites used to calculate the fen-to-bog transition timing as source data for main Figure 2D. Table S4. Radiocarbon dates from No Name Creek (latitude 60.633 N; longitude 151.083 W), Kenai Peninsula, Alaska, chronology data used in main Figure 3. Figure S1. Examples of aquatic pollen records from the Global Pollen Database. Shown here both aquatic pollen abundance (as percentage of total pollen sum) and z scores at each of 20 sites that have the longest (~10 ka at least) and most complete records among the 37 sites used in the synthesis. Figure S2. Average of aquatic pollen abundance and z scores at 500-year bins from 20 selected longest pollen records as shown in Figure S1 above.
