Assessment of chemical contamination in coastal water masses (Spain, Morocco, Tunisia, Sicily canal), using artificial stations of mussels. The MYTILOS1 cruise aimed to utilize the RINBIO network methodology around the western Mediterranean, in the northern part of the NW Basin. Experiments run in the French Mediterranean since 1996 by IFREMER were to be extended to Southern Mediterranean coasts, i.e. Spanish, Moroccan, Algerian and Tunisian coasts, as well as the Sicily Canal in Italy, on the basis of a standardized protocol. The data from MYTILOS2 cruise will supplement those obtained in 2004 and 2005 during the RINBIOC1 and MYTILOS1 cruises by including the coasts of North Africa, Southern Spain and the island of Pantelleria. In addition, the results will be used to complement the chemical contamination budget drawn up in the framework of the European Water Framework Directive's implementation. The survey was based on 2 major actions: 1) Artificial mussel stations were placed and recovered along a shoreline between Malaga (Spain) and Sicily (Italy), including Morocco, Algeria and Tunisia. 2) Sediment samples in addition to mussels samples were taken upon the partners' request. This falls under the MEDICIS project.

The cruise is a component of RAPID-WATCH, whose objectives are: to deliver a decade-long time series of calibrated and quality-controlled measurements of the Atlantic MOC from the RAPID-WATCH array and; to exploit the data from the RAPID-WATCH array and elsewhere to determine and interpret recent changes in the Atlantic MOC, assess the risk of rapid climate change, and investigate the potential for predictions of the MOC and its impacts on climate. Objectives of this cruise: to recover, calibrate and redeploy moorings from the eastern boundary and mid-Atlantic ridge subarrays of the 26.5N line of RAPID moorings.

<p>The purpose of WestMedFlux is to study thermal fields in ocean-continent transition zones in the Western Mediterranean, and the role of fluids and salt diapirs on the thermal field.</p>

The aims of this cruise were to elucidate the processes responsible for controlling iodocarbon concentrations and provide a dataset that can be used to develop modelled estimates of iodocarbon sea-air fluxes in tropical Atlantic waters.

<p>The Protevs Swot 2018 campaign aimed to explore the South Balearic zone in early spring to observe the small scales of the oceanic mixed layer using high-resolution sampling devices.</p> <p>The area was chosen because it was positioned below the SWOT satellite's planned swath in its validation/calibration period. In this sense, it is a precursor experiment of experiments for the year 2022 and as such exploratory of the scales that will be observable by this newly designed altimetry satellite.</p> <p>A particular focus was placed on an anticyclonic structure in the southern Balearic Islands that is systematically detectable by altimetry but which appears to be an artifact.</p> <p>These samplings were combined with fine analysis of the surface content of small phytoplankton by flow cytometry to study the shaping of the marine landscape by frontal physical processes.</p> <p> </p>

The objective of cruise JC103 was to service the moorings of the RAPID 26°N project that are deployed to monitor the Atlantic Meridional Overturning Circulation. For each mooring instruments were recovered, data were downloaded and instruments were redeployed. A number of CTDs were made to calibrate the instruments from the moorings. During passage from port of Spain to Nassau trial CTDs were completed in the waters of the Turks and Caicos Islands. After departing Nassau on 29th April work commenced on the western boundary sub-array comprising of moorings WBADCP, WBAL, WB1, WB2, WB2l, WB2h, WB4 and WB4L. The ship returned to Nassau on 6th May to disembark one person before sailing east once again. The final mooring of the wester sub-array was serviced on 8th May before continuing east to the mid-Atlantic Ridge (MAR) sub-array. Work on the MAR sub-array commenced on 13th May at mooring MAR0. The other moorings in this sub-array were MAR1, MAR1L, MAR2, MAR3 and MAR3L were all completed by 18th May. On the following day the NOG mooring was deployed and as the ship transited to the astern sub-array the first of 5 Argo floats was deployed on 21st May. The eastern boundary sub-array starts at EB1, which was serviced on 23rd May. Following this moorings at EB1L, EBHi, EBH1, EBH2, EBh3,EBh4 and EBH4L in the following days up until 31st May. A number of CTDs were completed form 31st may to 2nd June.

CD170 was a collaborative cruise with the Knorr cruise KN182_2. The latter cruise was conducted between 2 May 2005 and 26 May 2005. These cruises were completed as part of the UK Natural Environment Research Council (NERC) funded RAPID Programme and the US National Science Federation (NSF) funded MOCHA Programme to monitor the Atlantic Meridional Overturning Circulation at 26.5 degrees North. The primary purpose of both cruises was to service the 26.5 degrees North mooring array deployed in 2004 during RRS Discovery cruises D277 and D278. These cruises are the first annual refurbishment of this array.

Participation in validating the CAROLS airborne L band radiometer, during flights on ATR42. CTD/LADCP stations performed on repeated sections around the Bay of Biscay and calibration of CTD tags intended for deployment on sea elephants. The related projects are CAROLS, SMOS (TOSCA/CNES and ESA), EPIGRAM (LEFE/IDAHO).
