This site draws on the hard work of thousands of scientists from all over the world for making high-quality measurements in huge numbers and then releasing the data as aggregated and harmonized data collections for general, public use. We express our sincere gratitude to all contributors. Many datasets on this site retain as part of the metadata the names of data originators or the DOI of the original publication. Users are asked to cite this original material in own publications when using these data.

Technical and logistical support by Roland Koppe, Michael Günster and Jörg Matthes from the AWI computing center is gratefully acknowledged.

Development of the webODV online services was financially supported by the European Union's Horizon 2020 SeaDataCloud project under grant agreement number 730960 and the EMODnet Chemistry phase 4 project.
