The goal of SedDB is to provide a globally
integrated data set of sedimentary geochemistry,
easily and quickly accessible from any desktop.
This digital data collection aims to support
research and education on topics such as
geochemical cycles, mass-balances and fluxes,
paleoceanography and paleoclimatology. Initial
focus areas are the marine sediments from the
Izu-Bonin-Mariana and Central American Arcs, and
the Equatorial Pacific.

Creating a Query SedDB1.0 (to be released this
fall) has an enhanced interactive search tool
which allows queries to be made for any
combination of chemical data , creating
customized data sets directly relevant to
specific research topics.
SedDB0.1 Data Sites
Begin by selecting initial search criteria
Once selections are complete, the compiled
dataset and associated metadata can be downloaded
in .xls format

• Then either.continue with all items matching
  the criteria.orfurther refine the search by
  applying a variety of filters
• Lithology
• Age
• Data availability
• Sampling device
• Age model

Relevance of SedDB to the MARGINS community
Subducted sediments play a major role in
convergent margin magmatism, volatile cycling,
and mantle evolution. Geochemical data from
SedDB will provide a critical complement to data
in existing igneous databases
CHEMICAL ITEMS Majors Traces Stable
isotopes Radiogenic isotopes.. MATERIAL
TYPES Bulk sediment Pore waters Micro
fossils Leachates Minerals Grain size fractions
IBM sites containing sedimentary geochemical data
from SedDB (red) and igneous data from PetDB and
GEOROC (yellow) accessible through the EarthChem
website (www.earthchem.org).
CentAm sites containing sedimentary geochemical
data from SedDB (red) and igneous data from
PetDB and GEOROC (yellow).
The IBM and CentAm subduction areas are linked by
plate tectonics, in between lies the
carbonate-rich equatorial Pacific--one of the two
most important biogenic regimes in the oceans
which serves as a tectonic feeder of material
into these subduction zones. SedDB data is also
directly applicable to paleoclimate studies using
isotope data as proxies for ocean temperatures
and salinity.
META DATA Latitude/Longitude Elevation Lithology A

region
Contribute Data
SedDB actively encourages direct contributions of
geochemical data from investigators. Data sets
can be submitted in spreadsheet form, and should
include the metadata shown in the lower left box.
Data entry forms to guide you can be found at
www.seddb.org/seddbWeb/standards.jsp or contact
info_at_seddb.org and we will assist you. Visit
www.seddb.org to access the SedDB Dataset.
SedDB is supported by the National Science
Foundation and managed as part of the GfG Program
at Lamont Doherty Earth Observatory
