Abstract. The ATL2MED demonstration experiment involved two autonomous surface vehicles provided by Saildrone Inc. (SD) along a route from the tropical eastern North Atlantic to the Adriatic Sea between October 2019 and July 2020. This nine-month long experiment located in a transition zone between the temperate and tropical belts represents a major challenge in the use of SD. The sensors on board were subjected, to varying degradation degrees depending on the geographical area and the season, to biofouling with consequent deterioration of the acquired measurements. As a result, several maintenance along the mission's course were necessary.

We address the difficulty of correcting the data during a period of COVID-19 restrictions, which significantly reduced the number of discrete samples planned for SD salinity and dissolved oxygen validation. This article details alternative correction methods for salinity and dissolved oxygen. Due to the lack of in situ data, model products have been used to correct the salinity data acquired by the SDs, and then the resulting corrected salinity was validated with data from fixed ocean stations, gliders, and Argo floats. In addition, dissolved oxygen data acquired from SDs after correction using air oxygen measurements were tested and found to be in line with the oxygen values expected from temperature and chlorophyll-a data. The correction methods are relevant and useful in situations where validation capabilities are lacking, which was the case during the ATL2MED demonstration experiment. For future experiments, it is recommended that validation samples are collected more frequently. An overview over data availability is found in Section 5, Table 5.

Short summary
The ATL2MED experiment was a collaborative project involving European academic institutions and Saildrone Inc. These ASVs embarked on a nine-month mission that ranged from the tropical eastern North Atlantic to the Adriatic Sea, covering a region characterised by a transition zone between temperate and tropical climate belts. Nevertheless, challenges exist, with biofouling being one of the major problems affecting the measurement such as conductivity, dissolved oxygen and chlorophyll-a.
