GOSUD PROJECT

The Global Ocean Surface Underway Data (GOSUD) Project is an initiative of the International Oceanographic Data and Information Exchange ( IODE) of the Intergovernmental Oceanographic Commission (IOC) programme designed as an end to end system for data collected by ships as they traverse their ocean tracks. The goal of the GOSUD Project is to develop and implement the data system for ocean surface data, to acquire and manage these data and 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 from the ocean surface down to about 15m depth.

The main objective of GOSUD is to collect, process, archive and disseminate in real time and delayed mode, sea surface salinity and other variables collected underway, by research and opportunity ships.

GOSUD Data

About 50 vessels transmit thermosalinograph data in real-time. This map shows the latest 30 days of data acquired by this network and available from the Coriolis Argo GDAC ( Global DAta Center)

The dataset gathered within the GOSUD project is based on volunteer contributors which accept to share their data and to have a common data policy which includes common QC procedure, common distribution format and a central hub where the data are available

The existing GOSUD data providers are from various communities:

  • The ocean research community. In a routine mode, thermosalinograph (TSG) data from research vessels are transmitted either in near real-time or in delayed mode
  • Selected merchant ships have been equipped with thermosalinograph instruments. Most of the time, the data that comes from merchant ships are of a lower resolution than those from research vessels
  • From time to time, they are also punctual contributions. They may come from research vessels, sailing race ships or luxury cruise vessels
