September 2015 Cruise in the Mediterranean Sea (Rhone River delta and shelf)

Deep sea lander retrofitted for shallow work (< 100 m)

AIS equipment (ISEA IV Electrochemical Analyzer on top, Microcontroller on bottom, and SUBMAN-1 Micromanipulator in the background)

Benthic chamber samples after lander recovery: Each syringe represents a time point (right syringe contains leftover of the chemical tracer injected to trace transport across the sediment-water interface)
