Technicians from the Instituto Hidrográfico da Marinha (IH) and PLOCAN deployed a glider from the hydrographic vessel NRP Andrómeda, embarking on a four-week scientific mission under the European project JERICO-S3. The glider was launched southwest of Sesimbra, Portugal.  The activity, known as CBONDEX-TNA, represents a transnational access (TNA) requested by IH utilising a SeaExplorer glider from PLOCAN's VIMAS fleet, navigating the waters surrounding the coastal region of Lisbon to address specific scientific and operational challenges posed by the JERICO-S3 project. To accomplish this, the glider unit has been equipped with specialised oceanographic sensors aimed at measuring biogeochemical parameters (temperature, salinity, pressure, dissolved oxygen, chlorophyll, and turbidity) of seawater, from the surface to a maximum depth…
