The ice cap isotopic signature will be more negative than that in the ocean sediments. The ice cap isotopic signature will be more positive than that in the ocean sediments. The same isotopic signature in both the ice cap and in the ocean sediments which will have a negative value. All pollen types are preserved equally. All pollen types can be identified to the species level.
All plants produce the same amount of pollen.
Only the exine of the pollen grain is resistant to bacterial decomposition. An acidic pH in peats increases the rate of bacterial decomposition of pollen. Younger Dryas Phase b. Full Glacial Period c. Oak c. Elm d.
