## Digitization of Marine & Lacustrine Records of Climate Change(L-19)2009 Continuation requestNESDIS/National Geophysical Data CenterCarla Moorecarla.j.moore@noaa.gov_x000b_303-497-6339

## How this task contributes to modernization and utilization of a climate database:

**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 2008**Materials prepared/digitizedthrough October 27, 2008

- All approved, nonproprietary, L-19 scanned images are available online via the Index to Marine and Lacustrine Geological Samples

## L-19 Accomplishments for 2008Materials prepared/digitizedthrough October 27, 2008

-  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.

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

## 2008 Highlight: Seabed Photos in GeoMapApp

- Project L-19 Seabed photos are available online via the LDEO GeoMapApp viewer.
- _[http://](http://www.geomapapp.org/)__[www.geomapapp.org](http://www.geomapapp.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 website**

## 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 (OSU&SIO)
**Key-entry** **is complete, none proposed.**

- **FSU may have up to 6,000 x-rays if they do not purchase digital x-ray equipment*

**The 2009 extension, as proposed, should complete project L-19.**

**Notes:**
LDEO = Lamont-Doherty Earth Observatory of Columbia University
FSU = Antarctic Research Facility, Florida State University
OSU = Oregon State University, College of Oceanic and Atmospheric Sciences
SIO = Scripps Institution of Oceanography, University of California, San Diego
