The datasets provided by the various GOSUD contributors are collected and assembled in the database by Coriolis. They can be later accessed using a web selection tool or by downloading pre-formed files through FTP.
Different types of datasets are provided to GOSUD in Real Time (RT) or Near-Real Time (NRT). The main groups can be summarized as follows:

The delayed mode datasets:
To ensure a data quality in accordance with current research standards, in addition to the proper instalation, calibration and cleaning of the instrument, a delayed mode processing has to be applied to the dataset. It relies on:
- the carefull screening of the data to remove measurements performed in bad conditions (insufficient flow, air bubbles)
- the adjustment on external reference data from water samples or CTDs
DM-Data in GOSUD database
Some groups contributing to GOSUD provide delayed mode datasets.
The corresponding DM-data are included in the GOSUD database by replacing all real time data of the corresponding period, regardless of time sampling.
The original DM-datafiles are preserved and made available on FTP.
