Purpose | Research |
Objectives | Continuous investigations of atmospheric and marine properties and energy and material fluxes between ocean and atmosphere. The following projects will be carried out:
Autonomous measurement platforms for energy and material exchange between ocean and atmosphere (OCEANET). In order to provide a solid basis for the observational monitoring of energy and material exchange between ocean and atmosphere it is planned to develop an autonomous observation system for operational use onboard of 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), the GKSS research centre (ferry box, remote sensing of marine biology with ENVISAT/MERIS) and AWI Bremerhaven (CO2-system, marine infrastructure of Polarstern). Remote sensing of (atmospheric column) aerosol composition. The main goals are to characterize aerosol column properties, check their consistency with associated measurements of broadband radiative fluxes, and to monitor temporal evolution of aerosol properties in order to explore aerosol-cloud interactions and to establish meridional gradients of tropospheric aerosols. Shipboard ADCP measurements with Polarstern will enhance the availability of current sections and thus allow in the future to address the intraseasonal to seasonal variability of the transports of the main current branches. Furthermore, they will be used as a reference data set for the moored observation at the equator at 23°W. Live fish will be transported to Bremerhaven for further molecular genetic and physiological analyses. Long-term changes of abyssal temperatures in Vema Channel. It is planned to extend the time series of abyssal temperatures beginning 1972 by an additional CTD station at the Vema Channel. Parasound training and POSIDONIA tests. In Las Palmas further participants will come on board for a training course for self-efficient operation of the new hull-mount Parasound system P-70 and tests of the POSIDONIA system. |
