Event-controlled sampling system for marine research

The investigation of processes of particle exchange and transport using filtration sampler, bottom water sampler, sediment traps, or other equipment is one important task in marine research. In this paper, we describe a modular hardware solution (microcontroller, flash memory, analog-to-digital converter, system interface) together with embedded software, which is suitable for event-triggered control of systems, which have to work autonomously for longer periods. The system developed is able to respond automatically to rapid changes at the bottom of the sea, because the decision control is available directly at runtime.
