In one study they composed from diatoms, chironomids, pollen and near infrared spectroscopy and in the other study they use pollen chironmids and diatoms, so no tree rings!
One study go back to 10,000 BP and the other 9,000 BP.
Should i look at the fact one site has more human impacts than the other site? As one site has a road and rail network built, and the other is relatively low impact environment?
The place where u can get the papers is
but you need to have suscribed, i dont think you can get them for free!
i am so rediculously stuck! I swear i am just missing some key piece of information and when i put my hand on it, i will wonder why i was so confused by it!
