About NOAA Paleoclimatology
• NOAA’s National Climatic Data Center is the world's
largest archive of climate and paleoclimate data.
NCDC - Asheville
Paleo Branch - Boulder
• The Paleoclimatology Branch operates the World Data
Center for Paleoclimatology, which is one of 52 World Data
Centers that house a wide range of solar, geophysical,
environmental, and human dimensions data, and the only
World Data Center devoted to paleoclimatic data.
About NOAA Paleoclimatology
• We follow standardized guidelines for data archive and
distribution developed by the International Council for
Scientific Unions (ICSU), supporting the ICSU goal to
strengthen international science for the benefit of society,
and making all data freely available without restriction.
• We archive information so that it can be used by
paleoclimate experts, scientists from other fields, resource
managers and decision-makers, students, educators, and
interested citizens -- in short, by anyone interested in
gaining a better understanding of long-term variations in
climate and environment.

ABSTRACT: The Antarctic Vostok ice core provided compelling evidence of the
nature of climate, and of climate feedbacks, over the past 420,000 years..
GEOGRAPHIC REGION: Antarctica
PERIOD OF RECORD: 0 - 741 kyr BP
DATA: 1. Deuterium data from EPICA Dome C ice cores, 6.6-3140.5 metres. Column
1: Depth (m) at top of averaging interval Column 2: Depth (m) at bottom of
averaging interval Column 3: Age (years before 1950 on EDC2 timescale) at top
of averaging interval Column 4: Age (years before 1950 on EDC2 timescale) at
bottom of averaging interval Column 5: Mean age (EDC2 timescale, mean of
columns 3 and 4) Column 6: dD, permill
