Abstract

The Self Contained Autonomous Microstructure Profiler (SCAMP) is a free falling instrument, capable of measuring high-resolution profiles of temperature, salinity and fluorescence in the upper 100m. The falling velocity is controlled by moderating the buoyancy of the SCAMP with drifters or weights, in this case, pieces of lead. In order to obtain an approximate depth resolution of 1mm, during the expedition the velocity of the SCAMP was adjusted to 10 cm s-1, and verified after each cast. This high resolution allows us to resolve quantities related to the turbulence of the water column.
