Port of returnBremerhaven, Germany
ObjectivesContinuous investigations of atmospheric and marine properties and energy and material fluxes between ocean and atmosphere. The cruise will end in Bremerhaven on 20 May 2011 after a short stop in Las Palmas. In order to provide a solid basis for the observational monitoring of energy and material exchange between ocean and atmosphere it is planned in the context of the OCEANET project to develop an autonomous observation system for operational use onboard available cargo- and research vessels. The project is based on a network of expertise from IFM-GEOMAR (CO2-/O2-fluxes, photosynthetic status, energy budget, remote sensing), IfT (lidar measurements), the GKSS research center (ferry box, remote sensing of marine biology with ENVISAT/MERIS) and AWI-Bremerhaven (CO2-system, marine infrastructure of Polarstern). Continuous rate measurements of cosmic particles allow to estimate their dependency on latitude due to the Earth's magnetic field. Simultaneous cloud observations allow to investigate whether the concentration of cosmic particles influences cloudiness or vice versa. The concentrations and stable carbon isotope distribution of methyl halides will be measured in air and surface water along a South-North transect from Cape Town to Bremerhaven. Living animals which have been caught during ANT-XXVII/3 will be kept in the aquarium and the laboratory containers at 0°C water temperature to be transferred alive to Bremerhaven. Besides first measurements of enzyme activities, the main task will be to keep up the water quality in the aquaria. On the way from Las Palmas to Bremerhaven a training course on the Parasound system P-70 will be held.
