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

L-19 Accomplishments for 2008Materials
prepared/digitizedthrough October 27, 2008

• 21,653 photos, x-rays, logs, and descriptions
  were sent to HOV/Lason
• Another 5,000 x-rays and photographs are in
  preparation by participating institutions.
• All nonproprietary, approved scanned materials
  are publicly available online.
• Key-entry of all sampling logs for Oregon State
  University (OSU) will be completed in 2008.
• Progress was made on scanning cruise reports and
  descriptions of samples in the Scripps
  Institution of Oceanography (SIO) collection.
• Digitization of all seabed photographs taken by
  the LDEO ships Vema and Robert Conrad was
  completed in 2008.
• Several thousand color images of the sea floor
  from dives of the submersible Alvin were
  digitized.
• Additional pre-existing X-rays of climatically
  sensitive cores stored by the Antarctic Research
  Facility at Florida State University (FSU),
  newly-recovered from Principal Investigators, and
  from new cruises were also digitized.

2008 Highlight Seabed Photos in GeoMapApp
Project L-19 Seabed photos are available online
via the LDEO GeoMapApp viewer. http//www.geomapap
p.org
GeoMapApp was created by Dr. Ryan of LDEO, an
L-19 partner, with funding from the National
Science Foundation
GeoMapApp links to high-resolution photos on NGDC

L-19 Proposed Work for 2009

• Scanning
• 18,000 35mm color seabed photos (LDEO)
• 2,000 grayscale Antarctic core x-ray films
  (FSU)
• 31,500 pages of core descriptions (OSUSIO)
• Key-entry is complete, none proposed.

The 2009 extension, as proposed, should complete
project L-19.
FSU may have up to 6,000 x-rays if they do not
purchase digital x-ray equipment
