Integrated Global Ocean Services System

Project Description
IGOSS is an important data acquisition and management systems
that will form, with other existing systems, the "Marine
Meteorological and Oceanographic Operational Services" Module of
the Global Ocean Observing System (GOOS).

The Integrated Global Ocean Services System (IGOSS) is the
international SYSTEM for the collection and exchange of ocean
data (such as temperature and salinity) and the preparation and
dissemination of oceanic products and services. IGOSS is
coordinated jointly by the Intergovernmental Oceanographic
Commission (IOC) of the United Nations Educational, Scientific
and Cultural Organization (UNESCO) and the World Meteorological
Organization (WMO), and consists of national facilities and
services provided by participating member countries who share
data for mutual benefit.

The IGOSS system consists of three components: the IGOSS
Observing System (IOS), the IGOSS Data Processing and Services
System (IDPSS) and the IGOSS Telecommunications Arrangements
(ITA). In the IOS, naval ships, research vessels, and merchant
ships in the Ships-of-Opportunity Programme (SOOP) along with
fixed and floating buoys transmit oceanographic data such as
subsurface temperature and salinity in near-real time. The IDPSS
consists of several types of national, specialized and world
data centres for processing and dissemination data and data
products. The backbone of the ITA is the Global
Telecommunication System (GTS) of the WMO. BATHY and TESAC data
reports are transmitted over the GTS with headers that
correspond to the nation which made the observation and placed
the data on the GTS. The principal of free and open data
exchange for all member states is accomplished through the GTS.

Through IGOSS, observations, analyses and predictions of
important ocean features are available to users on an
operational basis, normally within 30 days or less. Ocean
observations of temperature, salinity, sea level, and currents
have a wide range of applications to commercial fishing,
hydrobiology, marine exloration, disaster prevention, marine
pollution and ocean modeling. IGOSS-derived data are used for
both operational and research applications. The data are quality
controlled at sea, by member states who acquired the data and at
data centres where they are archived. Data monitoring is
performed on a routine basis by the IGOSS Operations
Co-ordinator and a series of Data Monitoring and Statistical
Reports are available by FTP and via e-mail on the internet.

The most notable success of processing and quality controlling
global sets of temperature and salinity data is the Global
Temperature Salinity Profile Programme (GTSPP) There are also
groups such as the Group of Experts on Communications and
Products(GE/C&P) and the Task Team on Quality Control of
Automated Systems (TT/QCAS) that are comprised of experts from
member states that evaluate existing and new technologies for
acquiring more and improved oceanographic data, review WMO codes
and code tables for transmitting the data, and provide guidance
on equipment problems and corrections.

IGOSS products are disseminated promptly through the GTS and by
radio, radio facsimile, and various electronic and hard copy
mail systems. The IGOSS Products Bulletin, established in 1991,
compiles and publishes IGOSS global and regional products as a
valuable service to the scientific community and international
