Brief review of how this task contributes to
modernization and utilization of a climate
database

• Sea floor Lakebed sediments provide
  a valuable record of Climate
  Change
• The length, continuity, and time-resolution of
  data available from selected sediment cores
  is a unique resource for global change
  research
• Finely varved sediments from areas of rapid
  deposition provide a high-resolution record
  of past climates
• Volcanic ash layers contribute to climate
  studies on relatively short timescales
• Sediments from oceans lakes identify regional
  controls on the magnitude of climate change,
  and extend the record of climate change
  beyond ice core drilling data

Completed Core Logs Online
Oregon State University R/V Yaquina Cruise Y71-1
sample 2P is highlighted in pink. A portion of
the key-entered .PDF core log for Y71-1 sample 2P
is displayed. Boxes 7, 11, 12, 13 are waiting
for OSU to add supplementary information to the
logs before posting all other approved core
logs are online.

Proposed Work for 2007 Summary of Materials

• Scanning
• 18,720 8x11 grayscale printed pages
• 1,000 grayscale X-ray films, sizes up to 5 x
  20
• Key-entry
• 6,300 pages of handwritten core descriptions

See original proposal for scanning/entry
specifications
During 2006, LDEO fell behind in preparation of
photographs. They will have sufficient funding
and staff to make up the shortfall in 2007.
Original estimates were 14,000 per year for three
years.

Proposed Work for 2007 Participating Institutions

• Antarctic Research Facility, Florida State
  University (FSU)
• College of Oceanic and Atmospheric Sciences,
  Oregon State University (OSU)
• Graduate School of Oceanography, University of
  Rhode Island (URI)
• Lamont-Doherty Earth Observatory, Columbia
  University (LDEO)
• National Lacustrine Core Repository, University
  of Minnesota (LacCore)

Time Funding Estimates for 2007

• Estimated time needed to prepare data for CDMP
  contractors
• Less than 1 week per shipment has been needed to
  prepare data for the CDMP contractor.
• Funding requested for NOAA salaries in support of
  this task
• 10 of estimated cost for 2007 activities
• Approximately 18 of 1 FTE for data inventory,
  interactions with CDMP contractor, creation of
  FGDC-compliant metadata, updating databases for
  online access, and preparation and staging of
  digitized data for permanent archive.
• Part of a 2nd FTE for label generation and
  shipping.
• Part of a 3rd FTE for technical consultation on
  images.
