| Abstract | : | After two years of intensive measurements along European coastal waters (Tara-Europa expedition and HyperBOOST research project funded by the European Space Agency (ESA)), the TARA vessel (https://fondationtaraocean.org/en/home/) sampled the open waters of the Mediterranean Sea during an oceanographic campaign in August 2024, from Greece to the south of France. This campaign marked the first deployment of an Hypernets station, featuring the Hypstar, a new European-developed autonomous hyperspectral sensor (https://hypernets.eu), alongside numerous other continuous water quality measurements. From August 8 to 18, 240 measurements were collected under optimal conditions: calm seas, clear skies, and non-turbid waters. These data were compared with satellite observations from the VIIRS, OLCI, and MODIS missions, and particularly from the National Aeronautics and Space Administration (NASA) first hyperspectral mission, PACE (https://pace.gsfc.nasa.gov), the Plankton, Aerosol, Cloud, ocean Ecosystem satellite mission. The results of these data matchups are remarkable, showing an exceptional correlation between the Hypstar measurements and the satellite data, highlighting the surprising quality of the Hypstar sensor and the PACE satellite products. This first deployment phase of the Hypernets system, initially designed for coastal studies, paves the way for its adaptation to offshore applications, with promising prospects for global ocean monitoring. The hyperspectral observation of both coastal and open-ocean environments will undoubtedly open new avenues for understanding ocean (e.g., phytoplankton) dynamics, particularly in response to climate change and anthropogenic effects. The combined use of new satellite sensors and next-generation in situ measurements, within the framework of international cooperation between major space agencies, will make this possible. We will highlight the first key results combining this over 2-year-long expedition aboard the TARA vessel along with satellite ocean observations. |
