Doing science in a laboratory or on land, is something easy to do. But on a sailboat with limited resources and at sea, that’s another story.
This is why during our expeditions we implement science programs that only require few resources (energy, water, gas), so precious on board. The kits are all autonomous in energy.
The programs chosen are built to be feasible aboard a sailboat, both in terms of resources and logistics. The measurement kits to be deployed must therefore take up little space (except specific program) and are designed to be deployed quickly (about ten minutes, or up to an hour).
Some sensors require continuous operation and other measurements are done on an ad hoc basis, but in any case the science maneuvers to be carried out on board represent a minor part of the expedition logistics. Whether for the monitoring of measurements or the taking of a sample, we ask on average 1 hour per day every 3 to 4 days.
Among the programs that we propose for expeditions, there are some that we have developed , but also programs with which we have developed a partnership and for which we have become a relay structure.
Plankton sampling using a drift net, observation and photography under a microscope.
Launch of drifting floats ((JCOMMOPS)
Launch of observation beacons at sea for continuous monitoring of the oceans.
Measurement of current parameters continuously (temperature, pressure, acidity, etc …).
Meteorological observation (JCOMMOPS)
Pressure and temperature readings in the open ocean help improve global weather models while updating the local bulletin in real time.
Plankton sampling (Roscoff Marine Station)
Plankton sampling at sea for a DNA laboratory study (study of planktonic ecosystems).
Obs en Mer (Obs at Sea) programme
Opportunistic observation programme of marine mammals, seagrasses, jellyfish and rubbish. A very practical application to identify and report all observations of marine fauna.
Light pollution measurement (Globe at night)
By means of visual observation with a sky map or a measuring device, it is possible to measure the light pollution of the sky. The nocturnal luminosity produced by our civilisation has a major impact on the development of fauna and flora and on migrations.
