uses of ocean profile data
Uses of ocean profile data
  • There are a number of specific uses for ocean profile data and products derived from such data including but not limited to:
  • 1) Diagnostic studies describing role of the ocean as part of the earth's climate system;
  • 2) Boundary and Initial conditions for numerical models;
  • Ocean Data assimilation
  • 4) Verification for ocean and atmosphere simulations;
  • 5) "Sea truth" for satellite ocean altimetry measurements";
  • 6) Initial state for acoustic tomography inversions;
  • 7) Establishing fields of temperature and salinity for paleoclimatic studies (e.g. CLIMAP).
importance of ocean variables for climate system science
Importance of ocean variables for climate system science
  • temperature: earth’s heat balance;
  • salinity: earth’s freshwater balance;
  • oxygen: biogeochemical cycles;
  • nutrients: biogeochemical cycles, heat balance;
  • chlorophyll: biogeochemical cycles, heat balance;
  • plankton: biogeochemical cycles, heat balance.
world ocean database 2001 a heterogeneous database
World Ocean Database 2001(a heterogeneous database)

Global, comprehensive, integrated, scientifically quality-controlled with all data in one well-documented format.

Available on-line (web accessible) and via CD-ROM.

Updates to WOD01 will shortly be available on-line at the end of every month.

Why is WOD01 characterized as a “heterogeneous” database?

1) Data from 55,897 cruises;

  • Data from 3057 ships and other platforms;
  • Data from 489 institutes;
  • Data from 112 countries.

*Green indicates a “new” instrument type.

what are the problems associated with building world ocean database
What are the problems associated with building World Ocean Database?
  • 1) Many data sets received at NODC/WDC have problems such as missing or incorrect documentation.
  • It is labor intensive dealing with these problems.
  • Many data are received multiple times from different groups.
  • Often the “same” data are not exactly identical. The problem of identifying “exact” duplicates is trivial, the problem of identifying “near” duplicates is non-trivial.
  • Even when data originators are submitting data using “standard” formats they sometimes change these “standard” formats without informing recipients of the changes.
  • There are many data types and detailed metadata are required to make the data useful.
  • 4) Stewardship is a labor intensive process, e.g., acquisition and preparation of data, metadata, documentation.

history

September, 1988: Workshop on Ocean Data Files held at NODC, Washington, D.C.

  • Suggestion by S. Levitus “establishment of a “Historical Data Validation Project” to
  • “recover as much historical data as possible”.
  • September, 1990: International meeting held at NODC, Washington, D.C.
  • June 1990: NOAA support for data archaeology and rescue at NODC, Washington
  • February, 1992: Workshop on Ocean Climate Data, Greenbelt, Maryland
  • e) December, 1992: IODE meeting (Paris)
  • Proposal submitted for an international data archaeology and rescue project to IODE.
  • f) IOC Assembly meeting March, 1993:
  • IOC accepts the proposal and establishes the "Global Oceanographic Data Archaeology and Rescue" project
History
international aspects of ocean data archaeology and rescue
International aspects of ocean data archaeology and rescue
  • 1) The Global Oceanographic Data Archaeology and Rescue (GODAR) Project was established in 1993 by the IOC. Syd Levitus is Project Leader
  • European Community has sponsored the MEDAR/MEDATLAS Project for several years. Data Archaeology and Rescue focused on the Mediterranean and Black Seas.
  • Japan is the host for the IOC GODAR/WESTPAC project focusing on countries bordering the western Pacific Ocean.
  • Numerous countries have internal data archaeology and rescue projects.

The IOC Global Oceanographic Data Archaeology and Rescue (GODAR) Project

Six regional GODAR workshops have been held worldwide that encompass all countries that make oceanographic measurements.

Approximately 175 oceanographic data managers and scientists.

i) GODAR I - Obninsk, Russia May, 1993

ii) GODAR II - Tianjin, China March, 1994

iii) GODAR III - Goa, India December, 1995

iv) GODAR IV - Malta April, 1995

v) GODAR V - Cartagena, Colombia April, 1996

vi) GODAR VI - Accra, Ghana March, 1997

These meetings have resulted in the identification of substantial amounts of data at risk of loss due to media decay (e.g., magnetic tape and paper)..

international program support for data archaeology and rescue activities
INTERNATIONAL PROGRAM SUPPORT FOR DATA ARCHAEOLOGY AND RESCUE ACTIVITIES

Support for data archaeology and rescue activities in oceanography and meteorology and specifically for the GODAR project has come from many sources with support increasing with time, e.g.:

World Climate Research program’s CLIVAR program (WCRP, 1995; 1999)

and

IPCC (1996).
