Long-Term Ocean Climate Observations (LOCO) – D301/302
Cruise Diary – 7th April 2006	Launching profiling ocean drifters
Friday - Last day of the scientific program. A special mooring had to be recovered. Special, because this mooring contained a vertical moving platform with instruments that every 3 days moves from just above the seafloor to just below the surface. This platform is called a 'profiler'. It is an instrument that has been developed in recent years. It appeared to have functioned very well and had taken more than 100 profiles of temperature, salinity and currents in the past year. The scientific actions were finished with the launching of 4 Profiling Ocean Drifters (POD's) in the early afternoon. These instruments sink to the seafloor and with a time release they come to the surface. Once they are at the surface the temperature and salinity data that is measured is sent via satellite to the institute. After being at the surface they continue measuring and sending the data while drifting with the current.
