The Site Survey Data
Bank (SSDB) is a long-term repository for data submitted in support of
Integrated Ocean Drilling Program (IODP) proposals and expeditions.
Using tools available in the SSDB, Proponents submit digital files
(data, images, or documents) for evaluation by Reviewers, who make
recommendations to IODP through the panels of the scientific advisory
system. Submission deadlines are posted on the SSDB web site (http://ssdb.iodp.org),
and are typically one month before each panel meeting. Many of the
digital files in the SSDB are available for public access, although any
proprietary hold requirements specified by proponents are strictly
enforced. As proposals evolve into funded expeditions, the
SSDB also provides expedition packages of files to support drilling
operations and scientific analysis.
Uploading Data via
To upload data,
Proponents first need to request an account through the Register link
on the left hand menu, and then log on and use the My Account link to
request access to a specific proposal. SSDBupload is the
primary tool for uploading and submitting data files, along with the
metadata information that provides the necessary context for each
file. For step-by-step instructions on using SSDBupload, see
the guide on How to
Submit Files to SSDB. Proponents should check and revise
their metadata and data for accuracy and currency as needed before
clicking the final submit button in SSDBupload. After you submit your
final version with SSDBupload, SSDB staff takes over and performs
quality control and may contact you via email to any any
issues. Once quality control is complete, SSDB staff formally
publishes the files in the SSDB Digital Library.
Additional tools on
SSDB support the data submission process. SSDBstatus allows Proponents to check the status of all files that have been
uploaded, and as long as the final submit button was not pushed in
SSDBupload, SSDBstatus provides an independent opportunity to view and
edit metadata, and to make the final submission. SSDBquery is available to search for files that have been published. Although not
commonly used, SSDBCopy allows Proponents to copy sets of data from a previous proposal into a
new one, which may save time over re-loading each file.
SSDBcopy is also used by IODP-MI and Proponents to create expedition
The SSDB is also a
resource for data that have been released for public use.
Please note that Proponents are able to set the access
control to "hold" during the SSDBupload process; held data are never
served publicly. The SSDB will strictly enforce your
proprietary requirements. Security filters are in place to make sure
that any files you have placed on hold are only available to the
proponent and IODP-designated Reviewers, via password protection. The
metadata for files, however, such as the information that a file of a
particular type exists for a particular proposal, are made publicly
SSDB and the Proposal
The SSDB and the
Proposal Database are two separate systems that support the IODP
proposal process. When proposals are first submitted to IODP, the cover
sheet, supporting forms, and the narrative documents that describe the
scientific value of the project are stored in a "Proposal Database"
managed by IODP-MI. General information for Proponents, including
proposal submission deadlines and guidelines, is posted to http://www.iodp.org/drilling-proposals/.
Proposal documents are uploaded from http://proposals.iodp.org/cur/iodp_psp/.
The Site Survey Data
Bank (SSDB) holds data files that are submitted by Proponents in
support of their proposals, and serves the needs of Reviewers, as they
evaluate each drill site and proposal. It is a separate operation,
currently maintained at the Scripps Institution of Oceanography (http://ssdb.iodp.org),
under contract from IODP-MI, and hosted with high bandwidth and system
reliability at the San Diego Supercomputer Center.
Drill Site Names
controls the versioning of site names. Proposed drill sites tend to
move as ideas evolve, and to reduce confusion each new location is
given a new name in a sequence, rather than allowing an old name to
have new coordinates. Using information from proposal documents and
communications with Proponents, the official list of site names and
coordinates is maintained by IODP-MI and periodically updated in the
Downloading Published Data
SSDBquery is the
preferred tool for accessing data within the SSDB, and is available
from the menu bar on the left of the window. Searches can be
constrained by a variety of criteria, such as Proposal Number, Site
Names, Data Type (e.g., Bathymetry or SeismicMultiChannel), Data Object
Type (e.g., Map or Profile Image), Format (e.g., SEGY or PDF), Access
Control, Submission Date or lat-lon bounds.
The level of data
access depends on the kind of user. Those who are using the
site without an account can see metadata (a description of the kinds of
files held for each expedition), but not access any data.
Users with basic accounts, which are available from SSDB upon request,
can see the metadata and access data that have been released from
proprietary hold. Those with Proponent and Reviewer accounts
can access proprietary data for proposals for which they have
responsibilities. New accounts can be requested through the
Register link on the left menu, and changes in account status can be
requested from the My Account link visible on the left menu once logged
Each search produces a
results page (example below) that provides instructions on a number of
useful further actions, including sorting, viewing metadata, previewing
with a thumbnail browse image, downloading and viewing individual
files, viewing in Google Earth, and exporting selectable metadata into
spreadsheet format. For
users who do not have seismic viewing
software, a limited number of simultaneous licenses for the commercial INT Seismic Viewer Java
available for viewing and analyzing SEGY
files through the SSDB site. Clicking on the "INT" icon just to the
left of a SEGY filename in the SSDBquery results page will allow you to launch either the feature-rich, Java-based INT Seismic Viewer or the non-Java INT Simple Viewer.
For INT Seismic Viewer, you will need to authorize permission for the
application to run. Java is required on your computer for INT Seismic Viewer, but not for INT Simple Viewer. The actual SEGY file
remains on the SSDB server, while images are displayed on the user's

interactive Java application has now been retired. Most users preferred the simpler SSDBquery webform tool, with its Google Earth display.
SSDBlegacy provides a search interface for data, physical objects,
and basic proposal and site information submitted before 2005, when the SSDB library
was launched. Users can search by proposal numbers, site numbers, and a few
additional fields like proponent name (for proposals) and filename (for digital
