The EMSO-PT leg 2 oceanographic campaign was carried out on board RV Mário Ruivo, between 30 May and 02 June 2022, with the aim of deployment three EMSO-PT consortium equipments.

Portugal participates in the European consortium EMSO-ERIC (European Multidisciplinary Seafloor and water column Observatory, https://emso.eu/what-is-emso/ ) through the EMSO-PT project, a national consortium composed of members of R&D institutions and coordinated by IPMA.

The EMSO-PT leg 2 2022 oceanographic campaign was carried out on board IPMA research vessel (RV) Mário Ruivo, between May 30th and June 2nd, with the participation of technicians, scientists and students from IPMA, University of Algarve-CCMAR, INESC TEC, University of Évora, CoLAB +ATLANTIC and Polytechnic Institute of Setúbal.

The main objective of this campaign was to put into operation three equipments from the EMSO-PT consortium, namely: one EGIM (EMSO Generic Instrument Module), one Wirewalker and one ADCP. These equipment was placed at about 200 m depth for tests in a TUPEM (Title of Private Use of Maritime Space) off Sagres (Photos 1 and 2).

EGIM is equipped with several standardised sensors for comparison of time series of oceanographic parameters of the European sea, namely: conductivity (salinity), temperature, pressure, dissolved oxygen, hydrophone (acoustic sensor) turbidity and direction and intensity of the current. After the tests, EGIM will be placed at a depth of about 3000 m south of Sagres, constituting an observatory of the European EMSO-ERIC network.

The WireWalker is a sampler that runs a 150 m vertical profile in the upper ocean layer in yo-yo, driven by wave energy. It takes about 5 high resolution profiles (one reading every 0.2 m) per hour of temperature, conductivity (salinity), pressure, chlorophyll, turbidity and dissolved oxygen.

The ADCP (Acoustic Doppler Current Profiler) continuously samples a vertical current profile of 150 m in the upper ocean layer, with a vertical definition of 3 m.

The EGIM, Wirewalker and ADCP are part of the EMSO-ERIC European ocean observing network.
