Context and Overall Objectives
The Global Ocean Surface Underway Data (GOSUD) Project is an IOC programme designed as an end to end system for data collected by ships at sea.
The goal of the GOSUD Project is to develop and implement a data system for surface ocean data,
to acquire and manage these data
to provide a mechanism to integrate these data with other types of data collected in the world oceans.
For the purposes of this Project, the data concerned are those collected as a platform is underway and from the ocean surface down to about 15m depth.

Project Objectives
To organize the data that are presently collected and to work with data collectors to improve practices to meet the sampling and data accuracy set forth by GOOSto build a comprehensive archive containing sufficient meta-data that users will have clear information about accuracy and instrumentationto add value to the archive by refining and standardizing existing QA procedures on RT and DM data to provide data and information to users in timely fashionto return information to data collectors about the data they provideto work with scientific organizations interested in surace data to provide products to a broader community
The initial project plan is available from the web site:www.ifremer.fr/sismer/program/gosud/documentation.htm

GOSUD Real Time Quality Checks
Test 1 : platform identification
Test 2 : impossible date
Test 3 : impossible location
Test 4 : Position on Land Test
Test 5 : impossible speed
Test 6 : global ranges
Test 7 : regional ranges
Test 8 : spike test
Test 9 : gradient
Test 10 : climatology
Test 11 : instrument comparison
the result is a quality flag according to GTSPP flag scale

Links and CooperationARGO:Constant coopération. When combining TSG with surface data from profiles, better statistical computations and climatological analysis can be doneSatellite Community: presentation of GOSUD to the Aquarius/SMOS/Hydros joint meeting, April 2004. There is a strong interest in the GOSUD project, both from NASA and ESA, for calibration/validation of a sensor they are designing that can measure ocean surface salinity from space:
