An important goal of the dxpedition is furthering our knowledge about Clipperton Atoll and its ecosystem. As part of our application for our landing permit, certain scientific studies would be performed during our stay on the atoll. This program was elaborated in collaboration with Professor Christian JOST, director of the geopraphical research center of Paul Verlaine University in Metz and specialist of the atoll.

Program of the observation and scientific activities: March 6-18, 2008
1) Setting up of a weather station WS 3600: This automatic station set up between Bougainville Wood and the stele will record: - the temperatures in the shade and out in the open - the atmospheric pressure - the rainfall - the humidity - the speed and direction of the wind. The recording will take place every 15 minutes during our stay on the island.
2) Study of the propagation of radio waves: Recording of the different contacts according to the correspondent's emitting area, the time, the frequency and the sun activity. Comparison of these data with the theoretical models - simulations - realized before the activity.
3) State of the herbaceous plant coverage on the ring: Recording and photography of the bindweed patches and the flora on the ring and on the inside islets next to the ring. (Îles aux Sternes, île le crochet)
4) Observation of the birds living on the atoll: Recording in situ of the usual places of the birds on the island – especially the masked boobies, brown boobies, red-footed boobies, frigate birds, brown noddies, terns, coots,…
5) Observation to detect any human presence or occupation. Observation, positioning, photography and description of any tracks of alien presence and/or occupation on the atoll – landing tracks, graffiti, coconut tree cuttings, trash, new wrecks…
6) Checking of the preservation state of the geodesic marker: The geodesic marker was embedded in a crevice in the rock during Passion 2001 mission. (see photos in the appendix) We are to check it is still there, together with the identification plaque, check the preservation state of the mortar and repair it if need be.
7) Tides timetable: Recording of the actual times of a few high and low tides to compare with the theoretical model given by Mr Laurent Testut from the LEGOS – Laboratory of Spatial Oceanography and Geophysics Studies – in Toulouse- France.
