| Abstract | The Galathea 3 expedition started 11 August 2006 and re-entered Copenhagen on 25 April 2007. The cruise was available for science and education internationally, which constituted a unique opportunity as the ship circumnavigated the globe. The ship was comprehensively equipped with modern in situ sensors and during the cruise measurements and parameters were available at high time and space resolution from satellites with coverage along the ship’s track. Thanks to the educational AO-project accepted by the European Space Agency (ESA), acquisition requests for Envisat covered the entire cruise, and at many occasions also the exact locations at the time the ship passed. The satellite data was available in near real-time. The project has developed an easy data access via Google Earth, allowing qualitative analyses of all satellite data. Based on a Java applet, another catalogue is also available permitting on-line display and analysis together with the ability to download the data in full resolution. The ship carries a 1.5 Mbits/second communication connection, so position and in-situ data were received every 5 minutes and plotted in near-real-time in both data access locations. Of primary interest both for scientific and educational projects were MERIS, AATSR and ASAR satellite data, but other sensors for ozone, cloud coverage, ice concentration and sea surface height were also acquired and published. Furthermore third party mission data from SPOT and PROBA were used for educational purposes to demonstrate to schools the changes in time of the harbour cities called during the cruise (comparing present images and images of the past decades). Schools were offered many opportunities to work with satellite data. The web sites were available for everyone to browse and follow the expedition, but in addition we offered so-called running projects and case studies. Experienced teachers together with scientists have developed exercises to analyse Envisat data (SST, Chlorophyll content, surface-phenomena observed with ASAR) along the route. Furthermore enhanced educational material (case studies) include different themes, such as the Gulf Stream, the different issues related to harbours visited, the trace gases in the atmosphere and many others. All the education material is also accessible via school web sites such as the ESA-EDUSPACE. It is the intention that the material will be integrated to become an activity within the already existing module “Envisat for Schools” in EDUSPACE. The educational material including a series of images taken from satellite and photographs by people on-board will be used to produce a special Atlas to document the scientific results comprehensive for |
