LAST UPDATE: 11/2016 (addition of site location table) (Original receipt date by NOAA Paleo 1/1993) GEOGRAPHIC REGION: NorthEast USA PERIOD OF RECORD: 0 - 2,000 YBP DESCRIPTION: Mean summer (JJA) temperatures and Total annual precipitation for the past 2000 years reconstructed from pollen from lakes with laminated sediments. The laminations ensure a more precise time control than normally obtained from radiocarbon. FILE FORMAT: 3 columns: Years BP(=1975), JJA Temperature DegC, Annual Precip mm.
