Putting Your Data on the Map Cyndy Chandler WHOI Marine Chemistry Department Woods Hole Data Mongers / Ocean Informatics Meeting 4 April 2007 - WHOI
Finding the OI in WHOI What is Ocean Informatics? The work of Ocean Informatics is represented at the union of oceanography, information science and social science domains. Participants range from data and information managers to scientific researchers and educators. for more information see Karen Baker s work at SIO http://oceaninformatics.ucsd.edu/
my recent & current OI projects... US JGOFS DMO US Joint Global Ocean Flux Study http://usjgofs.whoi.edu OCB DMO Ocean Carbon & Biogeochemistry http://ocb.whoi.edu BCO-DMO Biological and Chemical Oceanography http://www.bco-dmo.org
U.S. JGOFS legacy data is available online or in data reports published on CD and DVD-ROM online access is via http or OpenDAP access to data system subset, list, plot or download all data http://usjgofs.whoi.edu/jg/dir/jgofs/
Ocean Carbon & Biogeochemistry project is still active; acquiring data database is available online online access is via http subset, list, plot or download data http://ocb.whoi.edu/jg/dir/ocb/
Biological & Chemical Oceanography project was funded in Fall 2006 by NSF Peter Wiebe and Bob Groman (Biology) Dave Glover and Cyndy Chandler (MCG) data team: Dicky Allison (Biology), Nancy Copley (Biology), Dave DuBois (G&G), Terry McKee (PO)
Biological & Chemical Oceanography no data available yet intend to provide data management support for projects funded by NSF OCE Biology and Chemistry Divisions data access will be provided from http://www.bco-dmo.org
Data Access data are loaded into an object-oriented relational database, QC d and metadata records created access via http and OpenDAP Live Access Server interface for some controlled vocabulary for column names
U.S. JGOFS Data System Web interface
Data Listing select dataset select variable (columns) select range (rows) view metadata
Live Access Server Interface configurable Web server data and metadata interface provides access to geo-referenced scientific data presents distributed data sets as a unified virtual data base (DODS/OpenDAP) uses Ferret as the default visualization application visualize data with on-the-fly graphics request custom subsets of variables in a variety of file formats access background reference material (metadata) compare variables from distributed sources
LAS enables a data server to unify access to multiple types of data in a single interface create thematic data collections from distributed data sources offer derived products on the fly offer variety of visualization styles customized for the data
U.S. JGOFS LAS Interface interface to data and metadata data sub-selection (selections, projections) multi-variable support gridded vs. in-situ data differencing multiple views (property-property, depth horizon, cruise tracks, overplots) multiple products (ps, gif, text, NetCDF)
LAS v6 select dataset and variables
select dataset select variable set constraints select view (XYZT) select output type selections: lat/lon time depth range LAS constraints
LAS select dataset select variable set constraints output output
