This cruise is part of the UK science contribution to the international SOLAS project (Surface Ocean Lower Atmosphere Study www.uea.ac.uk/env/solas/) which aims to advance our understanding of environmentally important interactions between the ocean and the atmosphere. Data collected during the cruise will help to determine the influence of coastal/shelf regions (20-200 km offshore) on microbiological activity in the ocean and chemical interactions between the ocean and the atmosphere. Deep water containing high concentrations of nutrients such as nitrate, and gases such as nitrous oxide and methane, rises to the surface (upwells) at the Mauritanian shelf edge and moves offshore. These nutrients can be chemically altered by sunlight and used by bacteria and microscopic plants to grow. The gases escape to the atmosphere and contribute to global warming. This cruise will sample the upwelled water as it moves offshore measuring its temperature, salinity, nutrient and gas content and the impact this water has on microbiological growth and atmospheric composition in order to improve international global climate models. The cruise has three scientific objectives: 1. To determine the role of upwelling on the supply, loss and air-sea exchange of climatically important gases produced by plankton 2. To determine the role of light in breaking down upwelled and recently produced dissolved organic matter and in producing climatically important trace gases 3. To determine the impact of nutrient enriched upwelled water on the spatial and temporal variability of plankton community structure and activity and resultant influence on biogenic gas flux

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.

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.

This equipment trials cruise has provided opportunities for test and verification of technology under development at the Proudman Oceanographic Laboratory (POL), the Scottish Association for Marine Science (SAMS) and the National Oceanography Centre, Southampton (NOC,S). This includes equipment developed during the first year of funding under OCEANS 2025 (theme 8). Testing technology in the ocean environment is invaluable in assessing fitness for purpose. Specifically, the cruise tested: A Spar wave buoy (NOC,S) biogeochemical sensors (NOC,S); an UAV system (NOC,S); a video grab system "HyBis" (NOC,S), A benthic Multicore (NOC,S), A benthic lander and associated torroidal Telemetry buoy (POL), and a shallow tow towfish (POL). Testing in Spanish waters (near Tenerife, Gran Canaria and Fuerteventura) has been invaluable. The time on passage has been minimised (the transition from deep to shallow water is less than a days steaming) and the calm conditions to the southwest of the islands in the consistent prevailing north easterly winds have enabled deployment and recovery techniques to be tried and optimised in safety.

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.

Overall objectives in the EU GO project are to assess the promising potential of seismic imaging for physical oceanography, in view of its combination of fine resolution and coverage unmatched by conventional oceanographic measurements. D318 was to provide the means of assessment by obtaining a unique, comprehensive, oceanographic and seismic dataset at the same time and place. Specific objectives for R.R.S. Discovery cruise 318a were to deploy four ADCP moorings, three adjacent temperature-logger moorings and STABLE, in an L-shape array in 750-1000m depth east of Portimao Canyon, carrying out adjacent CTD stations, deploy two OBH moorings, carry out seismic sections using the Ifremer high-frequency air-guns and streamer, accompanied by regular XBT and less frequent XCTD casts. In addition underway data was logged including ship-borne ADCP, surface temperature and salinity, meteorology, gravity and magnetics (to test new NERC magnetometers).
