The Global Ocean Surface Underway Data (GOSUD) Project is an 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 the mixed layer base.

Vision and mission

GOSUD aims at assembling in-situ observations of the world ocean surface collected by a variety of ships and at distributing quality controlled datasets.  Presently the variables considered by GOSUD are temperature and salinity.

Joining GOSUD

Contributions to GOSUD are encouraged. If you already operate a network, plan to set up a new network or have a dataset you estimate should be taken into account, please contact :
