Objectives/Activities
(i) Acquire, quality control, store and disseminate collected underway sea surface temperature and sea surface salinity data and metadata;
(ii) Maintain the database of sea surface salinity and temperature with appropriate metadata (including safeguarding high resolution delayed data);
(iii) Maintain and improve internationally agreed data management procedures and recommended practices, including metadata schemas, through close cooperation with relevant data centres (such as NCEI, SOCAT, OceanOps, SOOP,…);
(iv) Maintain, improve and implement procedures for the quality assessment of real time (RT) and delayed mode (DM) data, based on the GTSPP experience;
(v) Develop or adapt already existing, web interfaces to allow users to easily submit data and metadata, both in RT and DM;
(vi) Provide user access to data and metadata using state-of-the-art technologies;
(vii) Prepare proposals for the archival of additional underway data types;
(viii) Maintain a group of active experts involved in GOSUD.
Establishment/History
GOSUD was established as an IODE Project at IODE-XVI through Recommendation IODE-XVI/10 (see below) as the "Underway Sea Surface Salinity Data Archiving Project". In addition the JCOMM-1 meeting supported such a project urging that integration with other data collected at the same time be properly considered.
Governance/Management
The GOSUD project is managed by the Steering Group for GOSUD (SG-GOSUD).
The current co-chairs are:
Prior Mr Loic Petit de la Villeon (France) (until september 2020).
More information on the Steering Group is available here.
Data
Two types of TSG data files in GOSUD-NetCdf format can be downloaded from FTP directories.
Real time and Near real time data files: those files are created from the database as soon as they can be produced and are not updated.
Delayed mode data files. The last version submitted by the PIs is proposed.

Products
Products derived from thermosalinograph (TSG) observations of near surface temperature (SST) and salinity (SSS) are needed to serve many purposes. Find out more about the available data and scientific products from the GOSUD web site product page.
Recommendation IODE-XVI.10
UNDERWAY SEA SURFACE SALINITY DATA ARCHIVING PILOT PROJECT
The IOC Committee on International Oceanographic Data and Information Exchange,
Noting that the Ocean Observations Panel for Climate (OOPC) considers sea surface salinity data as critical for the study of the decadal and longer time-scale variations associated with deep ocean overturning,
Further noting that the number of countries collecting underway sea surface salinity data and the volume of data collected within coastal and open ocean monitoring programmes are rapidly growing,
Recognizing that presently there is little international co-operation in the exchange and management of these data,
Acknowledging the need to build effective international management of these data in co-operation with data providers and users to meet the requirements for temporal and spatial sampling resolution and measurement accuracy set forth by the OOPC,
Recommends the establishment of a Pilot Project for the management of these data with the Terms of Reference as attached in the Annex to this recommendation;
Invites the IOC Executive Secretary, in consultation with the Chairmen of IODE and OOPC, to establish a Steering Group to implement and monitor progress of the Pilot Project;
Invites the IODE Member States and other interested countries collecting underway sea surface salinity data to participate in the activities of the Steering Group.
Annex to Recommendation IODE-XVI.10
Terms of Reference of the Underway Sea Surface Salinity Data Archiving Pilot Project
Objectives of the Pilot Project:
(i) to acquire, quality control, store in standard format, and disseminate the collected underway sea surface salinity data
(ii) to establish close co-operation with relevant data centres to build a database and develop data management procedures and standards
(iii) to build a comprehensive archive for USSSAL data including appropriate metadata
(iv) to develop and implement procedures for quality assessment of real time and delayed mode data based on the GTSPP experience
(v) to provide data and information on line to users in a timely fashion
(vi) to ensure safeguarding of high resolution delayed mode data
(vii) to co-operate with data collectors to improve the data acquisition systems and to provide information on the data they provide
(viii) to maintain close links with other data collection and management programmes such as JCOMM and SOOP
(ix) to prepare proposals for the archiving of all potentially available underway data types
The Participants in the Pilot Project:
The Pilot Project will be carried out by a Steering Group composed of, inter alia, IFREMER/SISMER (France), MEDS (Canada), BSH (Germany), BODC (UK), ICES (Denmark), NCMR/HNODC (Greece), WDC for Oceanography - Silver Spring (USA).
