Karbe, Fritz Richard, Leibniz Institute of Marine Sciences, IFM-GEOMAR  OBJECTIVES AND BRIEF NARRATIVE OF CRUISE   enter sufficient information about the purpose and nature of the  cruise so                                                                                                                 as to provide the context in which the report data were collected.  After a breakdown of one engine during the previous leg, P380 was delayed by serveral days to sail on 20th March. Consequently, the planned hydrographic survey in the Logachev field area needed to be cancelled in order to not delay the following cruises to much. The research programme of P380 thus consisted of the recovery of 12 Ocean Bottom Seismometers (OBS), 12 Magneto Telluric Units (MT), the deployment and recovery of two Broadband Seafloor Compliance Stations (BSC) with 12 h and 24 h measurement period, as well as the recovery of a 120 m long mooring deployed in January 2009 in order to study mixing processes and near bottom currents in along rift valleys of the midatlantic ridge (MAR).  All these instruments were deployed in the vicinity of the Logachev Hydrothermal Vent Field (LHF) and are associated with the DFG project SPP 1144 "From the Mantle to the Ocean: Energy-, Material- and Lifecycles at Spreading Axes". Outside the 200 nm zone, during the transit from Fort de France, Martinique, to the working area and the following transit to Ponta Delgada, Acores, underway sampling of surface water intake took place in order to carry out onshore measurements of contaminants, i.e. concentrations of Nonylphenols and their Ethoxylates. During the whole cruise in international waters underway thermosalingraph (TSG) measurements of sea surface temperature (SST) and sea surface salinity (SSS), underway routine meteorological measurements with the on board DWD weather station, as well as current measurements with a vessel mounted RDI OS 75 kHz ADCP took place. On transit, 5 ARGO floats have been deployed.

Separate entries should be made for each distinct and coherent set of measurements or samples. Different modes of data collection (e.g. vertical profiles as opposed to underway measurements) should be clearly distinguished, as should measurements/sampling techniques that imply distinctly different accuracy’s or spatial/temporal resolutions. Thus, for example, separate entries would be created for i) BT drops, ii) water bottle stations, iii) CTD casts, iv) towed CTD, v) towed undulating CTD profiler, vi) surface water intake measurements, etc.  Each data set entry should start on a new line – it’s description may extend over several lines if necessary.  NO,    UNITS  :  for each data set, enter the estimated amount of data collected expressed in terms of the number of ‘stations‘; miles‘ of track; ’days‘ of                            recording; ‘cores‘ taken; net ‘hauls‘; balloon ‘ascents‘; or whatever unit is most appropriate to the data. The amount should be entered                            under ‘NO‘ and the counting unit should be identified in plain text under ‘UNITS‘.   PI  see page 2  NO  see above  UNITS  see above  DATA TYPE  Enter code(s) from list on cover page  DESCRIPTION  Identify, as appropriate, the nature of the data and of the instrumentation/sampling gear and list the parameters measured. Include any supplementary information that may be appropriate, e. g. vertical or horizontal profiles, depth horizons, continuous recording or discrete samples, etc. For samples taken for later analysis on shore, an indication should be given of the type of analysis planned, i.e. the purpose for which the samples were taken.
