The JGOFS/GLOBEC Data Management System for Serving Physical and Biological Oceanographic Data and Plans to Enhance It
  • Presented at the Open Geospatial Consortium Technical Committee Meeting – Natural Resources and Environment Working Group
  • R.C. Groman, P.H. Wiebe, N.H. Vine
  • and M.D. Allison
  • 18 January 2005
initial goals
Initial Goals
  • To understand the population dynamics of key species in terms of their coupling to the physical environment and in terms of their predators and prey.
ultimate goal
Ultimate Goal
  • To be able to predict changes in the distribution and abundance of target species as a result of changes in their physical and biotic environment as well as to anticipate how their populations might respond to climate change.
us globec
US GLOBEC
  • Georges Bank
  • Southern Ocean
  • Gulf of Alaska
  • Northeast Pacific Program
  • Multi-national participation
key data policy characteristics
Key Data Policy Characteristics
  • Dissemination to scientific investigators on a timely basis
  • Available when "useful"
  • Available to others outside the Program
data and information
Data and Information
  • Field data
  • Retrospective studies
  • Laboratory experimental results
  • Modeling data
  • Information
jgofs globec data management system
JGOFS/GLOBEC Data Management System
  • Distributed data servers
  • Web accessible
  • Supports plotting and downloading
developed by flierl et al for us jgofs program
Developed by Flierl, et al. for US JGOFS Program
  • Distributed data - client/server system
  • Open access - read only
  • Quality control on-going
  • Emphasis on access to data and information as quickly as possible
data acknowledgement policy
Data Acknowledgement Policy
  • Data sets being collected are most worthwhile in the context of all the other data sets being collected
  • Investigators must respect the ownership of the data and should request permission to use data. Collaboration encouraged.
object server model
Object/Server Model
  • The data object receives requests and responds with data; and a server connects applications to objects.
clients and servers
Clients and Servers
  • Browser application (Netscape, Internet Explorer, etc.)
  • Platform independent
  • More than just data served, information too
  • Based on "http" protocol
centralized starting point
Centralized Starting Point
  • GLOBEC machine at WHOI
  • Directory shows data categories or hierarchy
  • Encourages use of common field names (thesaurus)
example
Example
  • Start at home page
  • Go to data directory
  • Select data object
  • Data selection and projection options
  • Simple plots
  • Download options
enhancements
Enhancements
  • Improve the visual interface to the data (map versus tabular)
  • Retain “data driven” attribute of system
map tools
Map Tools
  • Live Access Server (LAS) – used by US JGOFS Program
  • MapServer
  • Generic Mapping Tools (GMT)
  • Digital Earth
web based data access tools
Web Based Data Access Tools
  • WEBCOAST
  • GoMOOS
  • Joint Global Ocean Flux Study (JGOFS)
  • National Coastal Data Development Center (NCDDC)
  • The Federation GIS Services Cluster
  • Distributed Oceanographic Data System (DODS)
  • PO.DAAC Ocean ESIP Tool (POET)
  • Comprehensive Large Array-data Stewardship System (CLASS)
  • EarthRef.org
  • SIOExplorer
  • Federal Geographic Data Committee (FGDC)
  • Australian Spatial Data Directory (ASDD)
  • United Nations Environment Programme (UNEP)
  • Animated Earth (NASA)
metadata and data access
Metadata and Data Access
  • Metadata currently presented as text via the web. Current plan is to convert to XML
  • Data access is via wget application or JGOFS/GLOBEC list application
learning about existing standards
Learning About Existing Standards
  • ECS, FGDC, GCMD common metadata
  • Mapping DIF to FGDC
  • Mapping DIF to Dublin Core
  • Guide to WMS
what s next
What’s Next
  • Implement metadata access via XML
  • Create WMS-based application to display data
